8(2) + 15(2)
16 + 30
46(7.75)
356.5 = price of fence before tax

356.5 / 100
3.565 * 6.3
22.4595 = tax

356.5 + 22.4595 = 378.9595 (total)

Chicago, Illinois has an elevation of 600 feet. Seely, California is -200 feet. What does 0 represent in the context of this situation?

Answers

Answer:

Sea level

Step-by-step explanation:

In geography, 'Elevation' is measured in relation to sea level, so sea level would be zero.

Thus, Chicago is 600 feet above sea level and Seely, California is 200 feet below sea level.

If there were nothing but flat land all the way from Seely to the ocean, sea water would come in and cover Seely. Fortunately for the people in Seely. California's coastal mountain range is between the town and the ocean, so that does not happen.

Answer:

It represents the "SEA LEVEL"

what is the density of the oak board? it is 5.5 inches wide, 1.5 inches thick and 3 feet long

Answers

multiply 5.5 the width with 1.5 by 3 which gives you 24.75 inches feet long.

5.5 x 1.5 x 3=24.75 that's your answer.

Answer:297 cubic inches, other person is incorrect.




Step-by-step explanation:5.5 inches* 1.5inches * 3 feet
Convert 3 feet to inches and you have 36 inches. So now it becomes 5.5inches*1.5inches*36inches = 297 cubic inches

For f (x) = 2x+1 and g(x) = x2 - 7, find (fºg)(2).

Answers

Answer:

Step-by-step explanation:

Your first step will be to set up the problem:

f(x) - g(x)

Next you will substitute in your values:

(2x + 1) - (x2 - 7)

The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:

2x + 1 - x2 + 7

Then combine your like terms:

2x - x2 + 8

Lastly put your expression in standard form (highest exponent to lowest)

-x2 + 2x + 8

You put $500 in a savings account. The account earns $20 simple interest in 6 months. What is the annual interest rate? Write your answer as a percent

Answers

Answer:

8%

Step-by-step explanation:

For simple interest, we use the equation I = PRT, where I is the interest earned, P is the principal/amount invested, R is the rate as a decimal, not percentage, and T is the time in years.

For this problem, we have to use 0.5 for T, because 6 months is 1/2 a year.

20 = (500)(r)(0.5)

20 = 250r

r = 0.08 = 8%

A number is divided by 3 and decreased by 5 is 6. What is the number???

answer = 23

Step-by-step explanation:

x-5=6*3

x-5=18

x=18+5

x=23

Answer:

33

Step-by-step explanation:

let the number be n , then the number divided by 3 is [tex]\frac{n}{3}[/tex] and decreased by 5

[tex]\frac{n}{3}[/tex] - 5 = 6 ( add 5 to both sides )

[tex]\frac{n}{3}[/tex] = 11 ( multiply both sides by 3 )

n = 33

The number is 33

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Suppose x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]

Multiplying both sides by 100, we get

[tex]7x+16x+27x=15000[/tex]

[tex]50x=15000[/tex]

Dividing both sides by 50, we get

[tex]x=\dfrac{15000}{50}[/tex]

[tex]x=300[/tex]

So, the amount invested at 7% is [tex]300[/tex].

The amount invested at 8% is

[tex]2(300)=600[/tex]

The amount invested at 9% is

[tex]3(300)=900[/tex]

Hence, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

A group of veterinary researchers plan a study to estimate the average number of enteroliths in horses suffering from them. Previously research has shown the variability in the number to be σ = 2. The researchers wish the margin of error to be no larger than 0.5 for a 99% confidence interval. To obtain such a margin of error the researchers need at least:
A. 53 observations.
B. 107 observations.
C. 106 observations.
D. 54 observations.
2.

A group of veterinary researchers plan a study to estimate the average number of enteroliths in horses suffering from them. The number of enteroliths is determined by surgery or ultrasound. This requires the participation of a radiologist and a surgeon in the study. The researchers decide that they should only enroll horses seen at the best veterinary hospital in the country to ensure correct counts. Such a hospital will typically see the most severe cases. The researchers will enroll the first 100 horses seen beginning on the day the study is funded. The resulting interval is likely biased because:
A. the first 100 horses seen is not an SRS of all horses with enteroliths and therefore never representative.
B. a sample of 100 horses is too small to obtain an unbiased estimate.
C. the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths.
D. All of the above

This requires the participation of a radiologist and a surgeon in the study. The researchers decide that they should only enroll horses seen at the best veterinary hospital in the country to ensure correct counts. Such a hospital will typically see the most severe cases. The researchers will enroll the first 20 horses seen beginning on the day the study is funded. The researchers will calculate a 95% confidence interval. The procedure is not valid because the:
A. sample size is too small for the central limit theorem to apply.
B. average number is not an integer and does not reflect any actual observation.
C. None of the above. The procedure is valid.
D. data are counts and, therefore, not Normally distributed.

4.

In a test of hypothesis for a mean, which statement is CORRECT?
A. The test requires that the sample mean is normally distributed; this requires that either the population distribution is Normal or the sample size exceeds 30.
B. As long as the population distribution consists only of positive values, sample size does not matter.
C. The population distribution can be any distribution because the sample mean is always Normally distributed.
D. The population must be normal because that is the only case when the sample mean is Normally distributed.

A "false negative," in which no effect is detected when in reality one exists, is an example of:
A. a Type I error.
B. the power of the test.
C. a Type II error.
D. None of the above

Answers

Answer:

1.) 107 observations

2.) the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths

3.) A. sample size is too small for the central limit theorem to apply.

4.) The test requires that the sample mean is normally distributed; this requires that either the population distribution is Normal or the sample size exceeds 30.

5.) a Type I error

Step-by-step explanation:

n = [(Zcritical * σ) ÷ E]²

n = sample size

Zcritical at 99% = 2.58

E = error margin = 0.5

Standard deviation, σ = 2

n = [(2.58 * 2) ÷ 0.5]²

n = [5.16 ÷ 0.5]²

n = (10.32)²

n = 106.5024

n = 107 observations

B.) The thought or decision that the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths will introduce a bias in the study.

C.) For central limit theorem ; sample size must be considerably large ; at least sample size, n ≥ 30

D.) Distribution must be normal it approximately normal, obeying the central limit theorem ; sample size must be considerably large ; at least sample size, n ≥ 30

The Washington Monument in Washington, D.C. is surrounded by a circle of 50 American flags that are each 100 feet from the base of the monument. The distance from the base of a flag pole to the top of the monument is 564 feet. What is the angle of elevation from the base of a flag pole to the top of the monument?

Answers

Answer:

Step-by-step explanation:

cosx=100/564

x=arccos(100/564)

x=79.79 degrees (to the nearest hundredth of a degree)

The angle of elevation from the base of a flag pole to the top of the monument is to be considered as the 79.79 degrees.

Calculation of the angle of elevation;

Since there is 100 feet from the base of the monument.

And, The distance from the base of a flag pole to the top of the monument is 564 feet

Now the angle should be like

cosx = 100/564

x = arc cos(100/564)

x=79.79 degrees

hence, The angle of elevation from the base of a flag pole to the top of the monument is to be considered as the 79.79 degrees.
