If Lee has a catering company. His staff is making pies for an event. there are 41 pies that have only rhubarb filling.
How many pies have only rhubarb in them?To find the number of pies that have only rhubarb filling, we need to subtract the pies that have rhubarb filling and another filling(s) from the total number of pies that have rhubarb filling.
We can use the given information to create a Venn diagram to visualize the relationships between the different fillings:
_______________
/ (3) \
/______ 14 ______\
/ / \ \
/ (1) / (5) \ (2) \
/_____/_______ \______\

(1) represents the number of pies that have only cherry filling,
(2) represents the number of pies that have only strawberry filling,
(3) represents the number of pies that have only rhubarb filling,
(4) represents the number of pies that have cherry and strawberry filling, but not rhubarb filling,
(5) represents the number of pies that have rhubarb and strawberry filling, but not cherry filling.
We can use the given information to fill in the values in the Venn diagram:
68 pies have cherry filling (1) + (4) + (6) + (7) + (8) + (9) + (10) + (14) = 68
73 pies have strawberry filling (2) + (4) + (5) + (7) + (8) + (9) + (10) + (14) = 73
30 pies have rhubarb and cherry filling (6) + (7) + (10) + (14) = 30
23 pies have rhubarb and strawberry filling (5) + (7) + (9) + (10) + (14) = 23
12 pies have only strawberry and cherry filling (7) = 12
14 pies have all three fillings (14) = 14
To find the number of pies that have only rhubarb filling, we can start by adding up the pies that have rhubarb filling and no other fillings: (3) + (6) + (9) + (10).
(3) is already the number of pies that have only rhubarb filling. For the other three regions, we need to use the values in the Venn diagram to calculate the number of pies with the given combinations of fillings:
(6) is the number of pies that have both rhubarb and cherry fillings, but not strawberry filling. Therefore, the number of pies that have rhubarb and no other fillings is 30 - 6 = 24.(9) is the number of pies that have both rhubarb and strawberry fillings, but not cherry filling. Therefore, the number of pies that have rhubarb and no other fillings is 23 - 9 = 14.(10) is the number of pies that have all three fillings, so they do not have only rhubarb filling.Adding up the number of pies that have only rhubarb filling from each region, we get:
Number of pies that have only rhubarb filling = (3) + (24) + (14) + (0) = 41.
Therefore, there are 41 pies that have only rhubarb filling.

Therefore, it is not even chance, but it is also not very unlikely. It is moderately likely that a yellow marble will be selected on the first draw.
What is Probability?Probability is a branch of mathematics that deals with the study of random events and their likelihood of occurring. It is a measure of the likelihood or chance of an event happening. Probability is expressed as a number between 0 and 1, where 0 means the event is impossible, and 1 means the event is certain.
In other words, probability is a way of quantifying uncertainty. It is used in various fields, such as statistics, physics, finance, engineering, and more, to help make predictions and decisions based on uncertain information. Probability theory provides a set of rules and tools for analyzing and manipulating random variables and events, and for calculating the probability of complex events.
The likelihood of a yellow marble being selected on the first draw can be calculated by dividing the number of yellow marbles by the total number of marbles in the bag:
likelihood of selecting a yellow marble = number of yellow marbles / total number of marbles

How to calculate the area of rectangle?The area of a rectangle is a measure of the amount of space it occupies in two-dimensional (2D) space. It is calculated by multiplying the length of the rectangle by its width. Mathmatically,
[tex]Area=length*width[/tex]
Now, Solving given problem,
The total area of the grid will be:Length of grid = 16 ft, Width of grid = 13 ft
Total area of grid = Length x Width = 16 ft x 13 ft = 208 sq ft
The area of the rectangle in the top right :Length of rectangle = 12 ft, Width of rectangle = 2 ft
Area of rectangle = Length x Width = 12 ft x 2 ft = 24 sq ft
To remove the top right rectangle from the tile dining area, subtract its area from the total area of the grid:
(Total area of grid) - (Area of rectangle in top right) = (208 sq ft -24 sq ft )= 184 sq ft
So, the expression for this calculation will be: (16 x 13) - (12 x 2) = 184 sq ft
The area of the vertical rectangles on the far left and right sides is calculated as follows:Width of vertical rectangles = 4 ft, Length of grid = 13 ft
Area of vertical rectangles = Width of vertical rectangles x Length of grid = 4 ft x 13 ft = 52 sq ft
The area of the rectangle in the top right:Length of rectangle = 12 ft, Width of rectangle = 11 ft
Area of rectangle = Length x Width = 12 ft x 11 ft = 132 sq ft
Add the areas of the vertical rectangles and the rectangle in the top right to get the total area of the tile dining area:
Area of vertical rectangles + Area of rectangle in top right = 52 sq ft + 132 sq ft = 184 sq ft
So, the expression for this calculation is: (4 x 13) + (12 x 11) = 184 sq ft
Hence, both of these expressions- (16 x 13) - (12 x 2) and (4 x 13) + (12 x 11) gives the square footage of the tile dining area based on the given information.

The probability of picking a blue marble or a marble with an odd number is 7/9.
How to solve the probabilityWe can use set theory to calculate the probability of picking a blue marble or a marble with an odd number. Let B be the set of blue marbles and O be the set of marbles with odd numbers. Then, we need to calculate the probability of the union of B and O.
P(B or O) = P(B U O) = P(B) + P(O) - P(B and O)
We know that P(B) = 4/9 and P(O) = 5/9. To calculate P(B and O), we need to count the number of marbles that satisfy both conditions, i.e., they are blue and have an odd number. There are two such marbles: B1 and B3.
Therefore, P(B and O) = 2/9, and the probability of picking a blue marble or a marble with an odd number is:
P(B or O) = P(B U O) = P(B) + P(O) - P(B and O) = 4/9 + 5/9 - 2/9 = 7/9

(b) [2 marks] Write a cosine function for Eva, who is just boarding the ride.
(c) (2 marks] Write a sine function for Matthew, who is on his way up, and is at the same height as the central axle of the wheel.
If Riders have to climb a m staircase to board the ride at its lowest point.
a. sine function for the height of Emma, who is at the very top of the ride when t = 0 is: h(t) = 60 sin(π/6 t).
b. a cosine function for Eva, who is just boarding the ride is: h(t) = m + 60 cos(π/6 t).
c. a sine function for Matthew is: h(t) = 30 sin(π/6 t).
What is the sine function for the height of Emma?(a) Let's assume that the Ferris wheel completes one full revolution in 12 minutes. The height of the Ferris wheel can be modeled by a sine function as it moves up and down periodically. When the Ferris wheel completes one revolution, it returns to its original position, so the period of the sine function is 12 minutes.
The maximum height of the Ferris wheel is 60 m, so the amplitude of the sine function is 60 m. When t = 0, Emma is at the very top of the ride, which means she is at the maximum height of the Ferris wheel. Therefore, the sine function for Emma's height, h(t), can be written as:
h(t) = 60 sin(2π/12 t)
Simplifying this equation, we get:
h(t) = 60 sin(π/6 t)
(b) Eva is just boarding the ride, which means she is at the lowest point of the ride when t = 0. The cosine function is ideal for modeling this situation, as it starts at its maximum value and reaches its minimum value after one-fourth of the period. Therefore, the cosine function for Eva's height, h(t), can be written as:
h(t) = m + 60 cos(2π/12 t)
Simplifying this equation, we get:
h(t) = m + 60 cos(π/6 t)
where m is the height of the staircase that Eva has to climb to board the ride.
(c) Matthew is at the same height as the central axle of the Ferris wheel, which means he is halfway between the maximum and minimum height of the ride. Therefore, the sine function for Matthew's height, h(t), can be written as:
h(t) = 30 sin(2π/12 t)
Simplifying this equation, we get:
h(t) = 30 sin(π/6 t)
Therefore sine function for the height of Emma, who is at the very top of the ride when t = 0 is: h(t) = 60 sin(π/6 t).

the area of Rectangle is 112 in sq. if the height is 8 in, what is the base length
Answer:
14cm
Step-by-step explanation:
112÷8=14
base length=14cm
Answer:
To find the base length of a rectangle, given its area and height, you can use the formula for calculating the area of a rectangle, which is:
Area = Length x Width
In this case, you are given that the area is 112 square inches and the height is 8 inches. Let's denote the base length as "x" inches.
So, the equation for the area of the rectangle becomes:
112 = x * 8
To solve for "x", you can divide both sides of the equation by 8:
112 / 8 = x
x = 14
Therefore, the base length of the rectangle is 14 inches.

7/10 divided by 1/3
Answer:
To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction.
So, 7/10 divided by 1/3 can be written as:
(7/10) ÷ (1/3) = (7/10) x (3/1)
Multiplying the numerators and denominators, we get:
(7 x 3) / (10 x 1) = 21/10
Therefore, the answer is 21/10, which is an improper fraction. We can simplify it to a mixed number by dividing the denominator into the numerator.
21 ÷ 10 = 2 with a remainder of 1, so the mixed number is:
= 1 1/10
Hence, the answer is 1 1/10 or 11/10.
Step-by-step explanation:
7/10 / (1/3) is equal to 7/10 * 3/1 = (7*3) / (10*1) = 21/10 = 2 1/10

A doctor wants to estimate the mean HDL cholesterol of all 20- to 29-year-old females. How many subjects are needed to estimate the mean HDL cholesterol within 3points with99 % confidence assuming s=14 based on earlier studies? Suppose the doctor would be content with 95 %confidence. How does the decrease in confidence affect the sample size required?
We need a sample size of at least 154 subjects to estimate the mean HDL cholesterol within 3 points with 95% confidence.
Dcreasing the confidence level from 99% to 95% reduces the required sample size. This is because a higher confidence level requires a larger z-value, which increases the sample size needed to achieve the desired margin of error.
What is Standard deviation?The standard deviation is a measure of the amount of variation or dispersion of a set of data values. It is calculated as the square root of the variance, which is the average squared difference between each value and the mean.
What is mean?The mean is a measure of central tendency that represents the average value of a set of data. It is calculated by summing up all the values in the set and dividing by the number of values.
According to the given information:
To estimate the required sample size, we can use the formula:
n = (z-value)² × s² / E²
where:
z-value = the z-score corresponding to the desired level of confidence
s = the population standard deviation (given as 14)
E = the desired margin of error (3 points)
For a 99% confidence level, the z-value is 2.576 (obtained from a standard normal distribution table). Plugging in the given values, we get:
n = (2.576)² × 14² / 3²
n = 267.89
We need a sample size of at least 268 subjects to estimate the mean HDL cholesterol within 3 points with 99% confidence.
For 95% confidence, the z-value is 1.96. Using the same formula, we get:
n = (1.96)² × 14² / 3²
n = 153.44
We need a sample size of at least 154 subjects to estimate the mean HDL cholesterol within 3 points with 95% confidence.
As we can see, decreasing the confidence level from 99% to 95% reduces the required sample size. This is because a higher confidence level requires a larger z-value, which increases the sample size needed to achieve the desired margin of error.

Answer: The type of probability illustrated here is theoretical probability, and option A correctly identifies it as such.
Theoretical probability is based on mathematical reasoning and analysis of possible outcomes. In this case, we know that there are 52 cards in a deck, and 13 of them are hearts. So, the probability of drawing a heart on the first card is 13/52. After the first card is drawn, there are 51 cards remaining in the deck, including 12 hearts. So, the probability of drawing a heart on the second card is 12/51. Continuing this process, we find the probability of drawing five hearts in a row to be:
P(heart) = (13/52) x (12/51) x (11/50) x (10/49) x (9/48) = 0.0104 or about 1.04%
This probability is based purely on mathematical reasoning and analysis of possible outcomes, and does not involve any actual experimentation. Therefore, it is an example of theoretical probability.

Calculating Income Tax Expense
Given the following.
Taxable Income $500k
Future taxable amounts $45k
Future deductible amounts $55k
Beginning Balances DTA $20k
Beginning Balances DTL $50k
Tax rate 40%.
1. What is the income tax payable?
2. What is the DTA year end balance?
3. What is the DTL year end balance?
4. What is the income tax expense?
5. What is the originating/reversing amount for the future taxable amount and for the deductible amount of the current year?
The income tax payable can be calculated as follows:
Taxable income = $500,000
Tax rate = 40%
Income tax payable = $500,000 x 40% = $200,000
What is the DTA year end balance?The DTA (Deferred Tax Asset) year-end balance can be calculated as follows:
Beginning balance DTA = $20,000
Future deductible amounts = $55,000
DTA year-end balance = $20,000 + $55,000 = $75,000
The DTL (Deferred Tax Liability) year-end balance can be calculated as follows:
Beginning balance DTL = $50,000
Future taxable amounts = $45,000
DTL year-end balance = $50,000 - $45,000 = $5,000
The income tax expense can be calculated as follows:
Income tax payable = $200,000
Add: Increase in DTL = $5,000
Less: Increase in DTA = $55,000 - $20,000 = $35,000
Income tax expense = $200,000 + $5,000 - $35,000 = $170,000
The originating/reversing amount for the future taxable amount and for the deductible amount of the current year can be calculated as follows:
Future taxable amount:
Origination amount = $45,000 x 40% = $18,000
Reversing amount = $18,000
Future deductible amount:
Origination amount = $55,000 x 40% = $22,000
Reversing amount = $22,000 - $20,000 = $2,000 (since the beginning balance of DTA was $20,000)

You are offered the following terms on a loan of $2250: 9.25 % interest per year paid back over 36 months. If monthly payments are $79.84, how much interest will you have paid once this loan is paid in full?
a) $624.24
b) $655.24
c) $2874.24
d) $1242.50
e) None of the above
Answer: $624.24.
Step-by-step explanation:
To find the total amount of interest paid on the loan, we first need to find the total amount of money repaid over the course of 36 months.
The total amount repaid is the monthly payment multiplied by the number of months:
Total amount repaid = Monthly payment x Number of months
Total amount repaid = $79.84 x 36 = $2,874.24
To find the total amount of interest paid, we need to subtract the original amount borrowed from the total amount repaid:
Total interest paid = Total amount repaid - Original amount borrowed
Total interest paid = $2,874.24 - $2,250 = $624.24
Therefore, the total amount of interest paid on the loan is $624.24.

The slope of g(x) is equal to the slope of f(x)
Therefore, the correct answer is: The slope of g(x) is less than the slope of f(x).
Where do the X and Y axes intersect on the coordinate plane, at position 0 0?The origin is the location where the two axes meet. On both the x- and y-axes, the origin is at 0. The coordinate plane is divided into four portions by the intersection of the x- and y-axes. The term "quadrant" refers to these four divisions.
We can use the slope formula to get the slopes of the lines f(x) and g(x):
slope of f(x) = (change in y)/(change in x) = (1 - (-2))/(1 - 0) = 3/1 = 3
slope of g(x) = (change in y)/(change in x) = (2 - 0)/(0 - (-4)) = 2/4 = 1/2
The slope of g(x) is 1/2, which is less than the slope of f(x), which is 3.
Therefore, the correct answer is: The slope of g(x) is less than the slope of f(x).

Explain probability
Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain. Probability is calculated by dividing the number of favourable outcomes by the total number of possible outcomes. Probability is used in many fields, including mathematics, statistics, science, economics, and finance, to make predictions and decisions based on uncertain events.
According to the given information

The following data values represent a population. What is the variance of the population? u = 12. Use the information in the table to help you.
A. 18 B. 41 O C. 12 OD. 80
x 3 11 13 21
(x-μ)² 81 1 1 81
The variance of the population according to the given table is option B 41.
What is variance?The spread or dispersion of a set of data around its mean is measured by variance. It has the same units as the original data and is calculated as the average of the squared deviations from the mean. Variance is a frequently used statistical term to describe the diversity or variability of a population or sample. When the variance is modest, the data points are closely grouped around the mean, whereas when the variance is great, the data points are widely dispersed.
The variance is given by the formula:
variance = (sum of squared deviations from the mean) / (number of observations)
Using the table we have sum of squared deviations from the mean:
81 + 1 + 1 + 81 = 164
variance = 164 / 4 = 41
Hence, the variance of the population according to the given table is option B 41.

April buys soil for her flowerpots. she uses 9 kilograms of soil for her violets and 4 kilograms of soil for her tulips. she has 3,000 grams of soil left for some daisies (1 kilogram = 1,000 grams) use the drop down menus to show how much soil she bought
April bought 16 kilograms of soil in total.
To show how much soil April bought
We need to add the amounts of soil she used for her violets and tulips. Since April used kilograms for violets and tulips, we need to convert the 3,000 grams to kilograms before we can add them up.
April bought:
9 kilograms of soil for violets
4 kilograms of soil for tulips
3 kilograms of soil for daisies (since 3,000 grams is 3 kilograms)
Therefore, April bought 16 kilograms of soil in total.

A 4-sided die, labeled 1–4 is rolled twice. Which outcome is not part of the sample space?
Answer: Let the experienced one help you out! Read the explanation down below! Brainliest?
Step-by-step explanation:
The sample space for rolling a 4-sided die twice consists of all possible pairs of outcomes, where each outcome is a number from 1 to 4. To find which outcome is not part of the sample space, we can list all the possible outcomes and then look for a number pair that does not appear.
Possible outcomes:
(1,1), (1,2), (1,3), (1,4)
(2,1), (2,2), (2,3), (2,4)
(3,1), (3,2), (3,3), (3,4)
(4,1), (4,2), (4,3), (4,4)
There are 16 possible outcomes, so one of the numbers from 1 to 16 is not part of the sample space. The missing outcome is (3,4) or (4,3), depending on the order in which the dice are rolled.
if 4-sided die, labeled 1–4 is rolled twice then 5,3 is not part of the sample space because the outcomes 5 and 3 are not part of the sample space.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
A sample space is a collection or a set of possible outcomes of a random experiment.
The sample space of rolling a 4-sided die twice can be represented by all possible ordered pairs of the outcomes, which can be listed as follows:
{(1,1), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (2,4), (3,1), (3,2), (3,3), (3,4), (4,1), (4,2), (4,3), (4,4)}
Therefore, if 4-sided die, labeled 1–4 is rolled twice then 5,3 is not part of the sample space because the outcomes 5 and 3 are not part of the sample space.
