Answer:

each square is 5". the base is 4x4 squares- so 20 inches square. 20x20= 400sq inches.

the semicircle at the top is 20 inches in diameter, which makes the radius 10 inches.

pi× 10^2= 314.16.

duvide that by 2 to get a semicircle- 157.8

so, the total area is the 400+ 157.8, for a total area of 557.8 square inches

Find the 13th term of the arithmetic sequence -3x+7, -5x+3, -7x-1, ...
oksano4ka [1.4K]

Answer:

a₁₃ = - 27x - 41

Step-by-step explanation:

The nth term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 3x + 7

d = a₂ - a₁ = - 5x + 3 - (- 3x + 7)

                 = - 5x + 3 + 3x - 7

                 = - 2x - 4

Then

a₁₃ = - 3x + 7 + 12(- 2x - 4)

     = - 3x + 7 - 24x - 48

     = - 27x - 41

A researcher records the repair cost for 8 randomly selected washers. A sample mean of $60.46 and standard deviation of $18.36 a
Anuta_ua [19.1K]

Answer:

The critical value is T = 1.895.

The 90% confidence interval for the mean repair cost for the washers is between $48.159 and $72.761

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 8 - 1 = 6

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 6 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.9}{2} = 0.95. So we have T = 1.895, which is the critical value.

The margin of error is:

M = T\frac{s}{\sqrt{n}} = 1.895\frac{18.36}{\sqrt{8}} = 12.301

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 60.46 - 12.301 = $48.159

The upper end of the interval is the sample mean added to M. So it is 60.46 + 12.301 = $72.761

The 90% confidence interval for the mean repair cost for the washers is between $48.159 and $72.761

(-3,7), (5,11) what is the slope and can u show me how u got it please ​
HACTEHA [7]

Answer:

<u>The formula for the slope is:</u>

\frac{y_2-y_1}{x_2-x_1}

<u>Assign each given point to a variable:</u>

  • (x₁, y₁) = (-3, 7)
  • (x₂, y₂) = (5, 11)

<u>Substitute in the values into the formula:</u>

\frac{y_2-y_1}{x_2-x_1}=\frac{11-7}{5-(-3)}=\frac{4}{8} =\frac{1}{2}

Therefore, the slope is 1/2.

const2013 [10]

Answer:

If we have to model a decimal using fraction , This is the way you should write

 1.\rightarrow a.b_{1}=\frac{ab_{1}}{10\text{or}(10^1)}\\\\2.\rightarrow a.b_{1}b_{2}=\frac{ab_{1}b_{2}}{100\text{or}(10^2)}\\\\ 3.\rightarrow a.b_{1}b_{2}b_{3}=\frac{ab_{1}b_{2}b_{3}}{1000\text{or}(10^3)}\\\\............\\\\\text{General rule}\\\\n.\rightarrow a.b_{1}b_{2}b_{3}.......b_{n}=\frac{ab_{1}b_{2}b_{3}.....b_{n}}{1000.....0\text{or}(10^n)}
