a. The probability that the total number of brownies sold for a random sample of 56 days is less than 2070 is approximately 0.0107.
b. The probability that 2X₁ + X₂ + 3X₃ + X₄ is less than or equal to 17.6
Explain probability
Probability is the 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 will not occur, and 1 means the event will definitely occur. Probability is a fundamental concept in mathematics and is used in many fields, including statistics, science, and finance.
According to the given information
a. The total number of brownies sold for a random sample of 56 days, Y, is a normal random variable with mean µ_Y = 56µ_X = 5638 = 2128 and standard deviation σ_Y = √(56)*σ_X = √(56)*6 = 25.21.
We want to find P(Y < 2070). Standardizing Y, we get:
Z = (Y - µ_Y) / σ_Y = (2070 - 2128) / 25.21 = -2.31
Using a standard normal distribution table or calculator, we can find that P(Z < -2.31) is approximately 0.0107. Therefore, the probability that the total number of brownies sold for a random sample of 56 days is less than 2070 is approximately 0.0107.
b. 2X₁ + X₂ + 3X₃ + X₄ is also a normal random variable with mean 2µ₁ + µ₂ + 3µ₃ + µ₄ = 2(3.6) + 0.9 + 3(1.8) + 7.4 = 18.5 and variance 4o² + o² + 9o² + o² = 14o².
We want to find P(2X₁ + X₂ + 3X₃ + X₄ ≤ 17.6). Standardizing the variable, we get:
Z = (17.6 - 18.5) / √(14o²) = -0.5735 / √(o²)
To find P(Z ≤ -0.5735 / √(o²)), we need to know the value of o². If o² = 1, then P(Z ≤ -0.5735) = 0.2831. If o² is a different value, we would need to adjust accordingly.
Therefore, the probability that 2X₁ + X₂ + 3X₃ + X₄ is less than or equal to 17.6

Nate is renting a compact car for 8 days and wants to buy the additional insurance. Using the information below, what is the total cost of the car rental if Nate fills the gas tank before he returns the car? Vehicle Type Daily Rental Rate Compact $56 Luxury Sedan $75 SUV $98 Minivan $90 Optional insurance cost is $10 per day. Gasoline charge of $3.50 per gallon if car returned not full.
the total cost of the car rental for Nate if he rents a compact car with the optional insurance and fills up the gas tank before returning the car would be $[tex]570.[/tex]
What is the total cost?To calculate the total cost of the car rental, we need to first determine the rental rate for a compact car for 8 days, including the optional insurance.
The daily rental rate for a compact car is $ [tex]56,[/tex] and the optional insurance costs $10 per day. Therefore, the total daily cost of renting a compact car with insurance is:
[tex]56 + 10 = 66[/tex]
To determine the total cost of renting the compact car for 8 days, we simply multiply the daily cost by the number of days:
[tex]66 \times 8 = $528[/tex]
Next, we need to determine the cost of gasoline if Nate returns the car without a full tank. The gasoline charge is $ [tex]3.50[/tex] per gallon, but we don't know how many gallons Nate will need to fill up the tank.
If we assume that a compact car has a gas tank capacity of around 12 gallons, and that Nate will need to refill the tank to its full capacity, then the gasoline charge would be:
$[tex]3.50 \times 12 = $42[/tex]
Finally, we can calculate the total cost of the rental, including the optional insurance and the gasoline charge if Nate returns the car without a full tank:
$[tex]528 + $42 = $570[/tex]
Therefore, the total cost of the car rental for Nate if he rents a compact car with the optional insurance and fills up the gas tank before returning the car would be $[tex]570[/tex].

Write an Algebraic Equation for each problem (include a let statement) and use it to solve the world problem
On number is eight less than five times another. If the the sum of the two numbers is 28, find the two numbers.
The smaller number is __.
The larger number is __.
The smaller number is 6 .
The larger number is 22
To solve this problem
Let's let x be the smaller number and y be the larger number.
From the problem, we know that one number is eight less than five times the other, so we can write:
y = 5x - 8
We also know that the sum of the two numbers is 28, so we can write:
x + y = 28
Now we have two equations in two variables. We can solve for one of the variables in terms of the other, and substitute that expression into the other equation to eliminate one variable.
Let's solve the first equation for x
x = (y + 8)/5
Now we can substitute this expression for x into the second equation:
(y + 8)/5 + y = 28
Multiplying both sides by 5 to eliminate the fraction, we get:
y + 8 + 5y = 140
Combining like terms, we get:
6y + 8 = 140
Subtracting 8 from both sides, we get:
6y = 132
Dividing both sides by 6, we get:
y = 22
Now we can use the equation y = 5x - 8 to solve for x:
22 = 5x - 8
Adding 8 to both sides, we get:
30 = 5x
Dividing both sides by 5, we get:
x = 6
Therefore, the smaller number is 6 and the larger number is 22.

4. Assuming that the rectangles have whole number side lengths, why is it possible to draw two different rectangles that have an area of 30 square inches but not possible to draw two rectangles with an area of 7 square inches?
Answer:
hm
Step-by-step explanation:
The reason why it is possible to draw two different rectangles that have an area of 30 square inches is that there are multiple pairs of whole numbers that multiply to 30. For example, a rectangle with dimensions 5 inches by 6 inches has an area of 30 square inches, and so does a rectangle with dimensions 2 inches by 15 inches.
However, the number 7 is a prime number, which means it can only be divided evenly by 1 and itself. Therefore, the only way to get an area of 7 square inches for a rectangle is by multiplying 1 and 7, which means the dimensions of the rectangle would be 1 inch by 7 inches. Since there are no other pairs of whole numbers that multiply to 7, it is not possible to draw two different rectangles with an area of 7 square inches.
Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options.
x2 + (y – 3)2 = 36
x2 + (y – 5)2 = 6
(x – 4)² + y² = 36
(x + 6)² + y² = 144
x2 + (y + 8)2 = 36
Answer: option (a) and option (e).
Step-by-step explanation:
Answer:
(a) and (e) are correct
Step-by-step explanation:
(a) x² + (y - 3)² = 6²
(b) x² + (y - 5)² = (√6)²
(c) (x - 4)² + y² = 6²
(d) (x + 6)² + y² = 12²
(e) x² + (y + 8)² = 6²
The general equation of a circle is:
(x - a)² + (y - b)² = r², where (a, b) represents the x-y coordinates of the centre, and r represents the radius.
Hence, by process of elimination, the options that have a diameter of 12 units and therefore, a radius of 6 units, are (a), (c), and (e).
Therefore, the correct choices are (a), and (e), as (c) has a circle centre of (4,0) and does not lie on the y-axis.
Consider the statement “If you are under age 17, then you cannot attend this movie.”

a. The converse, inverse and contrapositive are "If you cannot attend this movie, then you are under age 17.", "If you are over age 16, then you can attend this movie." and "If you can attend this movie, then you are not under age 17."
Writing the other versions of the statementThe original statement is an example of a conditional statement, which is a statement of the form "if A, then B." The part that comes after "if" is called the hypothesis, and the part that comes after "then" is called the conclusion.
To find the converse of the statement, we switch the hypothesis and conclusion. The converse of a conditional statement may or may not be true. In this case, the converse is not true.
To find the inverse of the statement, we negate both the hypothesis and conclusion. The inverse of a conditional statement may or may not be true. In this case, the inverse is not true.
To find the contrapositive of the statement, we switch and negate both the hypothesis and conclusion. The contrapositive of a conditional statement is always true if the original statement is true. In this case, the contrapositive is true.

Which missing x-value would make the table a function?
we can replace the second occurrence of x = -2 with x = 1:
What is function?
In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range.
For the table to be a function, each x-value must correspond to a unique y-value. To determine the missing x-value, we need to find if there are any repeated x-values with different y-values.
The x-value 3 is paired with y-values -3 and -1, which means that the table is not a function. Therefore, we need to replace one of the x-values that appears twice with a different value.
Since x = 0 is already paired with y = 5, we cannot use 0 as the replacement. The only other x-value that appears more than once is x = -2. Therefore, we can replace one of the occurrences of x = -2 with a different value.
For example, we can replace the second occurrence of x = -2 with x = 1:
x y

1 4
-2 -1
-2 -2

Does standard deviation means independent events
Standard deviation does not mean independent events.
Does standard deviation means independent events?No, the standard deviation is a measure of the spread or variability of a set of data. It measures how much the individual data points in a dataset deviate from the mean or average of the dataset.
Independence, on the other hand, refers to the relationship between two or more events, where the occurrence of one event does not affect the probability of the other event occurring.
Standard deviation is not directly related to the concept of independence. However, when calculating the standard deviation of a dataset, it assumes that each data point is independent and identically distributed. This means that the value of one data point does not affect the value of another data point, and that each data point is drawn from the same underlying distribution.

b) How fast will the wheel spin in revolutions per minute?
a) The angular velocity of the wheel is approximately 1.0667 radians per second. b) The wheel will spin at approximately 10.16 revolutions per minute.
What is angular velocity?Angular velocity is a measure of how quickly an object rotates or revolves around a fixed point, such as an axis or a center of rotation. It is a vector quantity that describes the rate of change of an object's angular position with respect to time, and is usually expressed in units of radians per second (rad/s) or degrees per second (deg/s).
According to given information:a) To find the angular velocity of the wheel, we can use the formula:
angular velocity = linear velocity / radius
In this case, the linear velocity of the hamster is 16 centimeters per second, and the radius of the wheel is 15 centimeters. So, we have:
angular velocity = 16 / 15
angular velocity = 1.0667 radians per second
Therefore, the angular velocity of the wheel is approximately 1.0667 radians per second.
b) To find the speed of the wheel in revolutions per minute, we need to convert the angular velocity from radians per second to revolutions per minute. There are 2π radians in one revolution, and 60 seconds in one minute. So, we can use the following formula:
angular velocity (in revolutions per minute) = angular velocity (in radians per second) * 60 / 2π
Plugging in the angular velocity we found in part (a), we get:
angular velocity (in revolutions per minute) = 1.0667 * 60 / 2π
angular velocity (in revolutions per minute) ≈ 10.16 revolutions per minute
Therefore, the wheel will spin at approximately 10.16 revolutions per minute.

A random sale of 40 flower shop customers was surveyed to find customers' favorite flowers. The table shows the results. The shop expects to sell 50 bunches of flowers on Sunday. How many bunches of each flower should the shop order?
Answer:
below
Step-by-step explanation:
To find out how many bunches of each flower the shop should order, we need to calculate the percentage of customers who preferred each flower, and then use that percentage to estimate the number of bunches needed for each flower.
First, we need to calculate the total number of customers who were surveyed:
Total customers surveyed = 8 + 4 + 8 + 20 = 40
Next, we can calculate the percentage of customers who preferred each flower:
Percentage of customers who preferred daisy = (8/40) x 100% = 20%
Percentage of customers who preferred gardenia = (4/40) x 100% = 10%
Percentage of customers who preferred mum = (8/40) x 100% = 20%
Percentage of customers who preferred rose = (20/40) x 100% = 50%
Now, we can use these percentages to estimate how many bunches of each flower to order.
Let's assume that each bunch contains 10 flowers (this is just an example, the actual number may vary):
Number of bunches of daisy to order = 20% of 50 bunches = 10 bunches
Number of bunches of gardenia to order = 10% of 50 bunches = 5 bunches
Number of bunches of mum to order = 20% of 50 bunches = 10 bunches
Number of bunches of rose to order = 50% of 50 bunches = 25 bunches
So, the shop should order 10 bunches of daisy, 5 bunches of gardenia, 10 bunches of mum, and 25 bunches of rose to meet the expected demand on Sunday.

You own 23 CDs. You want to randomly arrange 5 of them in a CD rack. What is the probability that the rack ends up in alphabetical order?
The probability that the CDs are in alphabetical order is
The probability of choosing 5 CDs in alphabetical order out of a collection of 23 CDs is approximately 0.00003 or 0.003%.
What is combination?
In mathematics, a combination is a way of selecting objects from a larger group of objects, where the order of selection is not important. A combination is a subset of objects that are chosen from a larger set without regard to the order in which they are selected.
The formula is given by:
C(n, r) = [tex]\frac{n!}{r!* (n - r)!}[/tex]
The total number of ways to choose 5 CDs from a collection of 23 CDs is given by the combination formula:
C(23, 5) = [tex]\frac{23!}{5!* (23 - 5)!}[/tex]
= 33649
This means there are 33649 different ways to arrange 5 CDs out of the 23 CDs.
Out of these 33649 ways, only one arrangement is alphabetical. For this to happen, the first CD chosen must be the first one alphabetically, the second CD chosen must be the second one alphabetically, and so on.
The first CD can be any of the 23 CDs. However, once the first CD is chosen, there is only one CD that can be the second one alphabetically, two CDs that can be the third one alphabetically, and so on. Therefore, the probability of choosing 5 CDs in alphabetical order is:
P = 1 / C(23, 5)
P = 1 / 33649
P ≈ 0.00003
So the probability of choosing 5 CDs in alphabetical order out of a collection of 23 CDs is approximately 0.00003 or 0.003%.
