Step-by-step explanation:

the total area = the area of full circle + the area of parallelogram = (π ×(8/2)²) + (28×7)

= (3,14 ×16)+(196)

Answer: 138 inches

Step-by-step explanation:

We can use proportions here, let h = height of the statue

height/height = shadow/shadow

\(\frac{h}{69} = \frac{94}{47}\)

h/69 = 2

*69 (h/69 = 2) *69

h = 138 inches

Answer:

-84+(-11)= -95

-84 + (-11) = -84 - 11 = -95

By the commutative property, adding a negative number is the same as subtracting that number as a positive; therefore, something + (-11) = something - 11. After changing the equation from -84 + (-11) to -84 - 11, we use regular addition properties, adding the tens place and ones place to get -95.

Answer:

The 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.133, 0.161).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which

z is the zscore that has a pvalue of \(1 - \frac{\alpha}{2}\).

For this problem, we have that:

\(n = 2305, \pi = \frac{339}{2305} = 0.147\)

95% confidence level

So \(\alpha = 0.05\), z is the value of Z that has a pvalue of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).

The lower limit of this interval is:

\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.147 - 1.96\sqrt{\frac{0.147*0.853}{2305}} = 0.133\)

The upper limit of this interval is:

\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.147 + 1.96\sqrt{\frac{0.147*0.853}{2305}} = 0.161\)

The 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.133, 0.161).

The test statistic is given as follows:

z = -1.77.

As the test statistic is less than the critical value for the left-tailed test, this evidence demonstrates that the direct mail campaign is not cost effective.

The equation for the test statistic is given as follows:

\(z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}\)

In which:

The parameters for this problem are given as follows:

\(p = 0.28, n = 165, \overline{p} = 0.2182\)

The critical value for a left tailed test with a significance value of 0.05 is given as follows:

z = -1.645.

The test statistic is then given as follows:

\(z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}\)

\(z = \frac{0.2182 - 0.28}{\sqrt{\frac{0.28(0.72))}{165}}}\)

z = -1.77.

i) If the duration of usage is 120 minutes, the total monthly charges for the mobile plan are $44.

ii)  If the total monthly charges for the mobile plan are $50, the duration of usage is 150 minutes.

iii) A formula, equation, or function connecting C, the total monthly charges, and n, the number of minutes of usage is C = 20 + 0.20n.

An equation is a mathematical statement defining that two or more mathematical expressions are equal or equivalent.

Equations use the equation symbol (=) to show equality.

Fixed cost per month = $20

Variable cost per minute = $0.20

i) Total minutes used = 120 minutes

Total cost, C = 20 + 0.20(120)

= $44

ii) Total monthly charges = $50

Duration of minutes = 150 (50 - 20 ÷ 0.20)

iii) Formula connecting C and n:

Total cost, C = 20 + 0.20n.

Thus, using the equation or formula of the total monthly charges C = 20 + 0.20n, we can determine the duration or the total costs, given any variable.

Perimeter of the parallelogram = 210 in.

Area of parallelogram = 2,484 in.²

Perimeter of parallelogram = 2(a + b), where a and b are its sides.

Area of parallelogram = (b)(h), where h is its height and b is the length of one of its bases.

Given:

a = 51 in.

b = 54 in.

h = 46 in.

Perimeter of the parallelogram = 2(54 + 51) = 210 in.

Area of parallelogram = (b)(h) = (54)(46) = 2,484 in.²

The solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7

The system of equations is given as

2x - y + 2z = -6

-3y + z = -2

2x - 3z = -4

Subtract 2x - 3z = -4 from 2x - y + 2z = -6

This is represented as

(2x - y + 2z = -6) - (2x - 3z = -4)

This gives

- y + 5z = -2

Multiply - y + 5z = -2 by 3

-3y + 15z = -6

Subtract -3y + 15z = -6 from -3y + z = -2

This is represented as

(-3y + z = -2) - (-3y + 15z = -6)

This gives

-14z = 4

Divide by -14

z = -2/7

Substitute z = -2/7 in - y + 5z = -2

- y - 5 * 2/7 = -2

This gives

- y - 10/7 = -2

Rewrite as:

y = 2 - 10/7

Evaluate

y = 4/7

Substitute z = -2/7 in 2x - 3z = -4

2x - 3 * 4/7 = -4

This gives

2x - 12/7 = -4

So, we have:

2x = 12/7 - 4

Evaluate

2x = -16/7

Divide by 2

x = -8/7

Hence, the solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7

Answer:

If your saying estimate this number in a decimal without calculators I think I might be able to help as illustrated below:

Step-by-step explanation:

2 5/6 shows that the whole number will be a 2. The 5/6 is a decimal below one as it is not one whole fraction. This means that we have to estimate the value of 5/6 and add that value to the number 2. 1/3 is a common fraction that is equal to about 0.33. This is because 0.33 + 0.33 + 0.33 is almost 1, which means 1/3 of one is indeed equal to 0.33.

This means we divide 0.33 by 2, because that would be equal to (1/3)/(2), or 1/6. 0.33/2 seems like it would be 16.5. 16.5 * 5, as in 5/6, would be 82.5.

I would then say that the estimate of 2 5/6 is 2.83.

4 shirts and 3 keychains

Step-by-step explanation:

1 shirt cost $30

So 4 shirts cost 4×30=$120

1 keychain cost $ 4.50

3 keychains cost 4.50×3=$13.50

Total =$120+$13.50=$133.50

Answer:

  4 shirts

Step-by-step explanation:

An equation can be written that relates the number of items bought and their cost. Let s represent the number of shirts bought. Then (7-s) is the number of keychains. The total cost was ...

  30s +4.50(7 -s) = 133.50 . . . . total cost of items bought

  25.50s +31.50 = 133.50 . . . . simplify

Answer:

The answer is 255.906

Step-by-step explanation:

multiply the value in meters by the conversion factor '39.370078740154'.

So, 6.5 meters = 6.5 × 39.370078740154 = 255.906 inches.

The required, 6.5 meters is approximately equal to 255.91 inches.

To convert 6.5 meters to inches, we can use the following steps:

Step 1: Convert meters to centimeters.

1 meter is equal to 100 centimeters. Therefore, to convert meters to centimeters, we multiply the value by 100:

6.5 meters * 100 = 650 centimeters.

Step 2: Convert centimeters to inches.

1 inch is equal to 2.54 centimeters. To convert centimeters to inches, we divide the value in centimeters by 2.54:

650 centimeters / 2.54 = 255.91 inches.

Step 3: Round to the desired precision.

If you want to round the result to a specific number of decimal places or significant figures, you can do so at this step. For example, rounding 255.91 inches to two decimal places gives us 255.91 inches.

Therefore, 6.5 meters is approximately equal to 255.91 inches.
