Step-by-step explanation:
When adding or subtracting fractions, they must have a common denominator....20 is the easiest for these...this then becomes
b + 16/20 = 35/20 now subtract 16/20 from both sides of the equation
b = 35/20 - 16/20
b = (35-16)/20 = 19/20
-16x^2+160x+120 in vertex form
The vertex form of the quadratic expression -16x² +160x+120 is -16(x - 5)² + 520.
What is vertex form?
Vertex form is a way to write a quadratic function in the form:
f(x) = a(x - h)²+ k
where "a" is the vertical stretch or compression factor, "h" and "k" are the x-coordinate and y-coordinate of the vertex of the parabola respectively. The vertex form allows you to easily identify the vertex and the direction of the parabola's opening.
To write -16x²+160x+120 in vertex form, we need to complete the square.
First, let's factor out the coefficient of x²:
-16(x² - 10x) + 120
Next, we need to add and subtract (10/2)² = 25 to the expression inside the parentheses:
-16(x² - 10x + 25 - 25) + 120
Now we can group the first three terms and factor the perfect square trinomial:
-16((x - 5)² - 25) + 120
Simplifying:
-16(x - 5)² + 520
Therefore, the vertex form of the quadratic expression -16x² +160x+120 is -16(x - 5)² + 520.

There are only Ured counters and g green counters in a bag. A counter is taken at random from the bag. The probability that the counter is green is 3
7
The counter is put back in the bag. 2 more red counters and 3 more green counters are put in the bag. A counter is taken at random from the bag. The probability that the counter is green is 6
13
Find the number of red counters and the number of green counters that were in the bag originally
Number of red counters in the original bag is 3, and the number of green counters is 7.
Let's use algebra to solve the problem. Let U be the number of red counters and G be the number of green counters originally in the bag.
From the first part of the problem, we know that
Probability (selecting a green counter) = G / (U + G) = 3/7
Solving for U in terms of G, we get
U = (7G - 3G) / 3 = 4G/3
So we know that there were 4G/3 red counters and G green counters in the bag originally. But since the number of counters must be a whole number, we can assume that there were 4R red counters and 3G green counters originally, where R and G are both integers and R + G is the total number of counters.
After adding 2 red and 3 green counters, the number of counters in the bag is now R + 2 + G + 3 = R + G + 5.
From the second part of the problem, we know that
P(selecting a green counter) = (G + 3) / (R + G + 5) = 6/13
Solving for R in terms of G, we get
R = (13G - 9G - 15) / 7 = 4G/7 - 15/7
Since R must be an integer, we can try different values of G to see if R is an integer. For example, if G = 7, then R = 3 and the total number of counters is 10.

An investment of $600 is made into an account that earns 6. 5% annual simple interest for 15
years. Assuming no other deposits or withdrawals are made, what will be the balance in the
account?
According to the investment, after 15 years, the balance in the account would be $1185.
To calculate the final balance after 15 years, we can use the formula for simple interest:
Simple Interest = Principal x Interest Rate x Time
In this case, the principal is $600, the interest rate is 6.5%, and the time is 15 years.
Simple Interest = $600 x 0.065 x 15
Simple Interest = $585
So the investment of $600 earns $585 in simple interest over 15 years. To find the final balance, we add the interest earned to the initial investment:
Final Balance = Principal + Simple Interest
Final Balance = $600 + $585
Final Balance = $1185

The market price of a dress was 80 000 at the botique
The dress was sold at a profit of 20%.
Profit percent is the percentage of profit earned on a product or investment, calculated as the profit divided by the cost price multiplied by 100%.
The profit or loss percent can be calculated using the following formula:
Profit/Loss percent = (Profit or Loss / Cost Price) x 100%
Here, the Cost Price (CP) of the dress is Rs. 2500, and the Selling Price (SP) is Rs. 3000.
Profit = SP - CP = Rs. 3000 - Rs. 2500 = Rs. 500
Therefore, the profit percent is
Profit percent = (Profit / CP) x 100%
Substitute the values in the equation
= (500 / 2500) x 100%

Congruent?Congruent is a mathematical term used to describe two figures or shapes that have the same size and shape. In other words, two figures are congruent if they have exactly the same dimensions and the same angles. When two figures are congruent, they can be superimposed on each other without any overlap or gap between them. Congruent figures are often denoted by the symbol ≅. For example, if two triangles have the same size and shape, we can write them as ∆ABC ≅ ∆DEF, which means that triangle ABC is congruent to triangle DEF. Congruent figures play an important role in geometry and other branches of mathematics.
Yes, the two triangles are congruent.
In Euclidean geometry, if two angles and a side of one triangle are equal to two angles and a side of another triangle, then the two triangles are congruent. This is known as the angle-side-angle (ASA) congruence criterion.

Therefore, the correct answer is A. We cannot determine whether g(-13) = 20 or not as -13 is outside the domain of g, but it is a possibility within the Domain range of g.
How are the domain and range determined?Determine the values of the independent variable x for which the function is specified in order to find the domain and range of the equation y = f(x). Simply write the equation as x = g(y), and then determine the domain of g(y) to determine the function's range.
Since g has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45, we can eliminate options B and D as they fall outside the range of g.
Since -13 is outside of the range of g, we are unable to verify whether g(-13) = 20 for option A.

A traffic expert wants to estimate the maximum number of cars that can safely travel on a particular road at a given speed. She assumes that each car is 20 feet long, travels at speed N, and follows the car in front of it at a safe distance for that speed. She finds that the number
of cars that can pass a given spot per minute is modeled by the function
N = 81s/20+20(s/24)^2
Answer: The given function is:
N = 81s / (20 + 20(s/24)^2)
where:
N = number of cars that can pass a given spot per minute
s = speed of the cars in miles per hour (mph)
To find the maximum number of cars that can safely travel on the road at a given speed, we need to find the value of s that maximizes the function N.
Taking the derivative of N with respect to s:
dN/ds = (81 / (20 + 20(s/24)^2)) * (20/24 - (2s/24^2) * (s/24))
Setting dN/ds to zero to find the critical point:
0 = (81 / (20 + 20(s/24)^2)) * (20/24 - (2s/24^2) * (s/24))
Simplifying and solving for s:
20/24 = (2s/24^2) * (s/24)
20 * 24 = 2s * s
s^2 = (20 * 24) / 2
s^2 = 240
s = sqrt(240)
s ≈ 15.4919 mph
Therefore, the maximum number of cars that can safely travel on the road at a speed of 15.4919 mph is:
N = 81s / (20 + 20(s/24)^2) = 81(15.4919) / (20 + 20((15.4919)/24)^2) ≈ 180.19 cars per minute.

show on the display monitors in the store. What is the probability that she selected 2 comedies and 1 action movie? EXPLAIN how the probability would
change if two more comedy movies were added to the list in place of the 2 mystery movies.
The probability of the store manager selecting 2 comedies and 1 action movie out of the list of 15 movies is 0.066
The probability of the store manager selecting 2 comedies and 1 action movie out of the new list of 15 movies is 0.165
Using this formula, we can find the total number of ways in which the manager can select any 3 movies from the list of 15, which is:
¹⁵C₃ = 455
Next, we need to determine the number of ways in which the manager can select 2 comedies and 1 action movie out of the list of 15 movies. To do this, we first need to determine the total number of comedies and action movies in the list, which is 4 and 5, respectively.
⁴C₂ x ⁵C₁ = 30
Therefore, the probability of the store manager selecting 2 comedies and 1 action movie out of the list of 15 movies is:
30/455 = 0.066
Now, if two more comedy movies were added to the list in place of the 2 mystery movies, the total number of comedies in the list would increase from 4 to 6, while the total number of action movies would remain the same at 5.
Using the same formula as before, the new total number of ways in which the manager can select any 3 movies from the list of 15 movies would still be 455.
The number of ways in which the manager can select 2 comedies and 1 action movie from the new list of movies can be found using the same product rule of probability as before. We can select 2 comedies from 6 in 6C2 ways, and 1 action movie from 5 in 5C1 ways. The new total number of ways in which 2 comedies and 1 action movie can be selected is:
⁶C₂ x ⁵C₁ = 75

Juliet concludes that short stories is the favorite type of book of the students in her school because 80% of the students in her class like short stories.
Use at least two sentences to explain why Juliet's sample may not be valid. Make sure to use facts to support your answer
Answer: See Bellow
Step-by-step explanation:
Juliet's sample may not be valid for several reasons. Firstly, her sample size of 20 students may not represent the entire student population at her school. If her class is not a random sample of the whole student population, her results may not generalize to the entire school. Additionally, the model may suffer from selection bias if she only surveyed students she knew liked short stories or if she conducted the survey in a way that only sure students responded. Therefore, it is essential to have a large and representative sample to ensure the validity of the conclusions drawn from the survey results.

The equation that represents the linear relationship in the table is D. y = 4x + 1.
Which equation represents the table of values?To find the equation that represents the linear relationship in the table, we need to determine the slope and y-intercept of the line that passes through the given points.
We can use the formula for the slope of a line, which is:
m = (y2 - y1)/(x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of two points on the line.
Using the first two points from the table, we get:
m = (1 - (-3))/(0 - (-1)) = 4/1 = 4
So, the slope of the line is 4.
To find the y-intercept, we can use the point-slope form of the equation of a line, which is:
y - y1 = m(x - x1)
Using the point (0, 1) and the slope m = 4, we get:

Therefore, the volume of the rectangular prism is 87.5 cubic yards.
What is prism?A prism is a transparent object, usually made of glass or plastic, that refracts or bends light as it passes through it. It has at least two flat surfaces, called faces, that are usually parallel and rectangular in shape, and two non-parallel faces, called bases, which are usually triangular in shape. When light enters a prism, it is refracted, or bent, as it passes through the prism and is separated into its component colors, creating a rainbow effect. Prisms are often used in optics and science experiments to study the properties of light, such as its wavelength and polarization. They are also commonly used in optical instruments such as binoculars, telescopes, and cameras to help focus and direct light.
The volume V of a rectangular prism is given by the formula:
V = length x width x height
In this case, the length is 5 yards, the width is also 5 yards, and the height is 3- and one-half yard.
To calculate the volume, we can plug this value into the formula:

2. INTEREST Marty invested $2000 in an account that pays at least 4% annual interest. He wants to see how much money he will have over the next few years. Graph the inequality y ≥ 2000 (1 + 0.04) ^× to show his potential earnings.
For the given inequality substitute the coordinates of x and y to form the graph of y ≥ 2000 (1 + 0.04)ˣ.
What is compound interest?Interest that is calculated on both the initial principle and any accrued interest is known as compound interest. This implies that the interest for the subsequent period is computed using the new total amount after the interest for the prior month has been added to the principal. If the interest rate and the duration are both high, the interest might add up to a sizable amount over time. Savings accounts, investments, loans, and other financial instruments frequently use compound interest.
For the given inequality we have:
For x = 0, y = 2000.
For x = 1, y = 2000(1 + 0.04) = 2080.
Plot the points on the graph to determine the graph.

Process control is based on comparing the current amount of outcome variation against outcome specifications.
Process control is a management approach that involves monitoring and adjusting a process to ensure that it meets its intended outcome specifications.
The goal of process control is to maintain consistent outcomes over time, despite natural variation in the inputs or other factors that may affect the process.
In order to achieve this goal, process control typically involves monitoring the process using statistical methods and comparing the current level of variation in the process outcomes against the desired outcome specifications.
If the variation is within acceptable limits, the process is considered to be under control.
If the variation is outside of acceptable limits, the process may require adjustment or other corrective action to bring it back into control.
Overall, process control is an important tool in quality management, manufacturing, and other fields where consistent outcomes are critical to success.
By monitoring and adjusting processes over time, organizations can ensure that their products and services meet the needs and expectations of their customers, while minimizing waste, errors, and other sources of variation.

Information provided; we can determine if the proportion of California college students who currently drink alcohol is different from the proportion nationwide by conducting a hypothesis test. Here are the steps:
The null hypothesis (H0) and alternative hypothesis (H1):
H0: The proportion of California college students who drink alcohol is the same as the nationwide proportion.
(p = 0.60).
H1: The proportion of California college students who drink alcohol is different from the nationwide proportion.
(p ≠ 0.60).
The sample proportion (p-hat), sample size (n), and the population proportion (p0):
p-hat = 0.66 (66% of the 450 California college students surveyed)
n = 450 (sample size)
p0 = 0.60 (nationwide proportion from CDC)
