Maria and Jeff collect data on the number of cars that pass through an intersection every Monday morning for 2 months. They record the findings as 78, 158, 63, 71, 56, 67, 75, and 64. They each use different methods to summarize the typical number of cars that pass through the intersection at the specified time and compare their findings. Jeff says that, on average, 79 cars pass through the intersection each Monday morning. Maria disagrees and says that the mean should not be used and uses the median instead to describe the typical number of cars that passes through the intersection on any given Monday morning.A) What is the median value of the data?

Answers

Answer 1

Answer: 56, 63, 64, 67, 71, 75, 78, 79, 158 (putting numbers in least to greatest makes this easier) so what you would do to find the median is remove the first and last number until you have one number remaining.
Therefore the answer should be 71

Andrew solved the following inequality, and his work is shown below:−4(x + 8) + 25 ≤ −2 + 1(x − 50)
−4x − 32 + 25 ≤ −2 + 1x − 50
−4x − 7 ≤ 1x − 52
−5x ≤ −45
x ≤9

What mistake did Andrew make in solving the inequality?

Answers

For this case we observe that we have the following inequality:

-4 (x + 8) + 25 ≤ -2 + 1 (x - 50)

The first step is the distributive property on both sides of the inequality:

-4x - 32 + 25 ≤ -2 + 1x - 50

This step is written correctly.

The second step is to add similar terms:

-4x - 7 ≤ 1x - 52

This step is written correctly.

The third step is to pass the number 7 adding on the right side of the inequality:

-5x ≤ -45

This step is written correctly.

The last step is to divide between 5 both sides of the inequality. Then, multiply by -1. When multiplied by -1, the direction of the inequality changes:

x ≤9

This step is written incorrectly.

Answer:

Andrew did not change the symbol of the inequality in the last step.

(B) when dividing by -5, he did not change the < to >

Olivia has 21 coins in her drawer. Nine of the coins are nickels, and the rest are pennies. What is the total value of the coins in her drawer?

Answers

21 COINS
9 are NICKLES
all the other are pennies
21 - 9 =12
so 12 pennies
1 nickle is 5 cents so
5*9 = 45 cents so
45 + 12 = 57
so the answer is 57 cents

do 21-9=12. So there are 12 pennies. then since you are finding the value of the coins you do 9*5=45 since there are 9 nickels and each nickel is 5 cents. Then you add 45+12=57. So the value is 57 cents.

An original piece of artwork is 2.75 feet by 2.25 feet a reprint of the artwork is 22 inches by 18 inches are the pieces similar? if so what is the ratio of their corresponding side lengths?

Answers

Yes, the Repainted Artwork is similar to the Original. The 22*18 inch repaint can be recaclculated into a 1.83*1.5 feet repaint. Both can be multiplied by about 1.5 to equal 2.75*2.25. Therefore, the ratio is 1.5.

PLEASE HELP!!!!! "A country's population in 1991 was 70 million. In 1998 it was 74 million. Estimate the population in 2010 using the exponential growth formula. Round your answer to the nearest million."

Answers

Answer:

81 million

Step-by-step explanation:

A = Pe^rt

Let's break this equation down.

A is the total you will have.

P is the starting value.

R is the rate

T is the time.

Let's find the rate first.

74000000 = 70000000e^7r

Divide each side by 70mil

74000000/70000000 = e^7r

Then take the ln() of each side.

ln(74000000/70000000) = 7r

0.0556 = 7r

r = 0.0079

Now we can find how many people will be there in 2010.

A = 70,000,000e^(19 * 0.0079)

A = 81336530.2373

Now we round to the nearest million, leaving us with 81 million.
