In year, 2004, I put $20.00 into an account to save. This account annual interest fee is 0.002%. However, every 10th year the interest rate get doubled and is now 0.004%. After, the 10th year it goes back to the original interest rate of 0.002% annually. If I check the amount I know have in total included my principal of $20.00, in the year of 2021. What would the total amount be of putting it there

Using the sample data to test the hypothesis, we have that:

77% of the sample of 1176 adults rated themselves as above average drivers, that is:

[tex]0.77(1176) = 906[/tex].

Thus, the actual number of respondents who rated themselves as above average drivers is 906.

At the null hypothesis, we test if the proportion is [tex]\displaystyle \frac{7}{10} = 0.7[/tex], that is:

[tex]H_0: p = 0.7[/tex]

At the alternative hypothesis, we test if the proportion is greater than 70%, that is:

[tex]H_1: p \geq 0.7[/tex]

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

In this problem, the parameters are [tex]\overline{p} = 0.77, p = 0.7, n = 1176[/tex].

Thus, the value of the test statistic is:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.77 - 0.7}{\sqrt{\frac{0.7(0.3)}{1176}}}[/tex]

[tex]z = 5.24[/tex]

The p-value of the test is the probability of finding a sample proportion above 0.77, which is 1 subtracted by the p-value of z = 5.24.

Looking at the z-table, z = 5.24 has a p-value of 1.

1 - 1 = 0.

The p-value of the test is 0, which is less than the standard significance level of 0.05, thus we can conclude that the proportion respondents who rated themselves as above average drivers is greater than 0.7.

Answer:

Step-by-step explanation:

L = Length

W = Width

W = 2L

   2W + 2L = 174

2(2L) + 2L = 174

            6L = 174

              L = 29 ft

W = 2(29) = 58 ft

Step-by-step explanation:

complementary angles sum to 90°

Let angle 1 =  x

    angle 2 =  3x - 8

  3x - 8 + x = 90

             4x = 98

               x = 24.5°

3(24.5) - 8 = 65.5°

or

90 - 24.5 = 65.5°

Answer: 5/11

Step-by-step explanation:

Answer:

558

Step-by-step explanation:

The sum of the first n numbers is ½n(n + 1)

which is the left most number in each row number n

so finding the row containing 526

½n(n + 1) > 526

½n² + ½n > 526

n² + n > 1052

n² + n - 1052 > 0

n > (-1 + √(1² - 4(1)(-1052))) / 2(1)

n > 31.938

so 526 is almost to the end of the 32 row.

The end of that row is ½(32(33)) = 528

so 526 resides two spaces to the right of 528

The end of the row below it, row 33, is ½(33)(34) = 561

As each row is one number longer than the previous row, we count back

2 + 1 = 3 numbers from the end to find what is under 526

561 - 3 = 558

Answer:

Step-by-step explanation:

From the intercept of the line of best-fit, the car’s approximate initial velocity was of 5.7 m/s.

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator. These points are given on a table or in a scatter plot in the problem.

For this problem, the input and the output are defined as follows:

Hence the points are given by:

(2, 13.1), (4, 19.8), (6, 28.1), (8, 34.6).

Using these points and a calculator, the equation is:

v = 3.64s + 5.7

The intercept of 5.7 represents the initial velocity in m/s.

Answer:

what is the question please tell me on comment

Answer:

18 gallons

Step-by-step explanation:

We'll find out how much of the total container was lost when pouring out by subtracting 2/3 from 1/2.

2/3 = 4/6

1/2 = 3/6

4/6 - 3/6 = 1/6

1/6 of the total amount the container could hold was lost when 3 gallons was poured out. This means that 1/6 of the container equals to 3 gallons. We can then simply multiply 3 by 6 to find the number of gallons of liquid the container can hold.

3 * 6 = 18 gallons

Checking my answer:

18 * 2/3 = 6 * 2 = 12

12 - 3 = 9

1/2 of 18 = 9

This means that our answer is correct.
