Answers

Answer:

5 / 12

Step-by-step explanation:

You must have common denominators in order to add or, in this case, subtract.

Answer:

[tex] \frac{15}{12} - \frac{5}{6} [/tex]

We have a simple formula that can be reduced We will put it into a combined form [tex]1 \times \frac{3}{12} - \frac{5}{6} [/tex]Find a common numerator [tex]1 \times \frac{3}{12} - \frac{10}{12} [/tex]So our answer is [tex] \frac{5}{12} [/tex]

Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. For the scenario below, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem.

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.

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

Answers

Answer:

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

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%

This is due in 10 minutes please help me

Answers

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%.
