Amy made a circle graph of the U.S. population for 2000. This is the data that she used and the graph that she made.

Answers

The true statement is (b). No, because males and females should add up to 100% of the population.

How to determine the true statement?

The complete question is added at the end of this solution.

From the complete question, we have the following percentages

Male = 26%Female = 27%

When the above percentages are added, we have

Total = 26% + 27%

Evaluate the sum

Total = 53%

The above shows that the display of the circle graph is accurate.

This is so because the total percentage of the male and the female population must add up to 100%

Hence, the true statement is (b). No, because males and females should add up to 100% of the population.

A mail carrier can deliver mail to 36 houses in 30 minutes. Mark wants to determine how many houses the carrier can deliver mail to in 7.5 minutes at this rate. He thinks that to find the answer, he should do the following.

1. First divide 36 houses by 30 minutes to find a unit rate of 1.2 houses per minute.
2. Then multiply 1.2 houses per minute by 7.5 minutes to get 9 houses.

Answers

Mark's method is correct, because even though it is impossible to deliver mail to 1.2 houses in minute,  it represents the unit rate of houses per minute .

Is Mark's method correct?

The first step is to determine the unit rate of houses per minute. This can be done by dividing 36 houses by 30 minutes.

36/30 = 1.2 houses per minute

The second step is to multiply 1.2 by 7.5: 1.2 x 7.5 = 9 houses

The future value of Investment A is 9511.81

The future value of Investment B is 68,351.02

The future value of Investment C is29.067.07.

What are the future values?

When an amount earns a compound interest, it means that both the amount invested and the interest rate already accrued increases in value at the next compounding date. For example, if interest is compounded quarterly, both the amount invested and the interest accrued increases every quarter.

The formula for calculating future value:

FV = P (1 + r)^nm

FV = Future value P = Present value R = interest rate m = number of compoundingN = number of years

Investment A = 7500 x [(1 + (0.08/4)]^(4 x 3) = 9511.81

Investment B = 53,000 x [(1 + (0.06/12)]^[(4 x 12) + 3) = 68,351.02

Answer:

x = 24°

Step-by-step explanation:

If two parallel lines are being intersected by the same line, the opposite inside angles are congruent. This means that ∠EFH should be equal to ∠JHF. However, we cannot set these angles equal because we do not know the value of ∠JHG.

Line IG is intersected by line HJ. This means the value of ∠JHG is 24° (180° - 156° = 24°). Know that we know this value, we can set up an equation to find "x".

∠EFH = 2x

∠JHG = 24°

∠GHF = x

∠EFH = ∠JHF                                  <----- Opposite interior angles are equal

∠EFH = ∠JHG + ∠GHF                   <----- Break ∠JHF into 2 angles

2x = 24 + x                                      <----- Insert values

x = 24                                             <----- Subtract x from both sides

Answers

A state uses a combination of three letters (A-Z) followed by three digits (0-9) for their license plates. So, there are 17576000 license plates can be made.

Given that, license plates consists of 3 letters followed by 3 digits.

Let the numbers on license plates be N

Let the letters on license plates be L

So, the license plate consisting of 3 letters and 3 digits will be LLLNNN.

Letters can be anything from A to Z.

There are 26 letter combinations for the first letter. That is applicable for the following 2 letters.

So, the combination for letters = 26×26×26 = 17576

Numbers can be anything from 0 to 9.

There are 10 combinations for each place.

So, the combination for numbers = 10×10×10 = 1000

Now, the combination for letters and numbers= 17576×1000

                                                                        =  17576000

Answers

The bond price 101.78

What is the price of a bond?

A bond price is the present value of its future cash flows discounted at the yield to maturity which is the appropriate discount rate.

Specifically, the bond price is the present value of annual coupons for 2 two years and the face value discounted at the 8% yield to maturity.

We can determine the bond price using the present value formula of a single cash flow for all cash flows.

PV=FV/(1+r)^N

FV=future cash flow(annual coupons for 2 years and face value)

annual coupon=face value*coupon rate

face value=100

coupon rate=9%

annual coupon=100*9%

annual coupon=9

r=discount rate=8%

N=year of cash flows, 1 for year 1 and 2 for year 2

bond price=9/(1+8%)^1+9/(1+8%)^2+100/(1+8%)^2

A 99% interval would be wider than both-the value of t for a 99% interval is greater than both that for a 90% interval and that for a 95% interval b. Choose the correct answer below 13 O A Increase the value of B. Manually reduce the sample standard deviation OC. Increase the number of observations by an appropriate amount OD. Decrease the number of observations by an appropriate amount FILL IN THE BLANK The same restriction enzymes are used to ____ a piece of DNA called donor DNA _____ a gene of a different organism, such as the gene that produces insulin or growth hormone. ILL GIVE BRAINLIEST!!!Two input-output pairs for function f(x) are (6,52) and (1,172). Two input-output pairs for function g(x) are (2,133) and (6,1). Paige says that function f(x) has a steeper slope. Formulate each function to assess and explain whether Paige's statement is correct. (4 points) An agent moves from one broker-dealer to another. Notification of the change of employer must be made by the: A. agent only B. agent and new broker-dealer C. old broker-dealer and new broker-dealer D. agent, old broker-dealer and new broker-dealer Calculate the resistance of a platinum wire that is 2 m in lenth and has a diameter of 0.1cm. The resistivity of platinum at 25 deg C IS 9.83 X 10^-6 OHMS-CM. What implications dose this result have for the construction of a resistance thermometer useing platinum? (q008) what term did salvador dal invent that describes the foundation for his painting persistence of memory? .The following table shows the relationship between a computer's CPU speed and its benefits and costs. Assume that all other features of the computer are the same (that is, CPU speed is the only source of variation), and only the CPU speeds listed below are available for purchase.CPU GHzTotal benefitMarginal benefitTotal costMarginal cost2.0$1,000$9002.5$1,400$1003.0$300$1,2003.5$1,900$1,5004.0$2,000$400a) Fill the empty cells.b) Find the optimal choice of CPU, given the cost of upgrades. Select all of the factors that determine the extent of nitration in a nitration reaction.

The capacity of the process is increased by less than 50%. The capacity of the process is increased by more than 33%. The capacity of the process may decrease. The capacity of the process is increased, but it is usually not doubled. find a gnf grammar equivalent to the following (cnf) cfg: s-> aa | 0 a -> ss | 1 find the dimensions of the box with volume 8000 cm3 that has minimal surface area. (let x, y, and z be the dimensions of the box.) (x, y, z) =
