Answer:

Width of one side is 30 inches, Length of one side is 22 Inches and Areas is 660 Inches Squared

Step-by-step explanation:

W= 8 + L

P = ( W x 2 ) + ( L x 2 )

104 = 2( 8 + L )  + ( L x 2 )

104 = 16 + 2L + ( L x 2 )

104 = 16 + 2L + 2L

104 = 16 + 4L

-16     -16  

88 = 4L

88 / 4 = 4L / 4

22 = L

W  = 8 + 22

W = 30

Area = L x W

A = 22 * 30

A = 660

Answer:

The width of the rectangle is 56 and the length is 48

Step-by-step explanation:

divide the perimeter in half (52 + 52)

then subtract 4 from one of the 52's

you get the answer of 56 and 48

Your answer can be checked by conferming that 56 - 48 = 8 so the width of a rectangle is 8 inches longer than its length.

The mean annual tuition and fees for a sample of 15 private colleges was with a standard deviation of . A dotplot shows that it
Fudgin [204]

Answer:

Step-by-step explanation:

The question is incomplete. The complete question is:

The mean annual tuition and fees for a sample of 15 private colleges was $35,500 with a standard deviation of $6500. A dotplot shows that it is reasonable to assume that the population is approximately normal. You wish to test whether the mean tuition and fees for private colleges is different from $32,500. State the null and alternate hypotheses. A) H0: 4 = 32,500, H:4=35,500 C) H: 4 = 35,500, H7:35,500 B) H: 4 = 32,500, H : 4 # 32,500 D) H0:41 # 32,500, H : 4 = 32,500

Solution

We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

H0: µ = 32500

For the alternative hypothesis,

Ha: µ ≠ 32500

This is a two tailed test.

Since the number of samples is small and the population standard deviation is not given, the distribution is a student's t.

Since n = 15,

Degrees of freedom, df = n - 1 = 15 - 1 = 14

t = (x - µ)/(s/√n)

Where

x = sample mean = 35500

µ = population mean = 32500

s = samples standard deviation = 6500

t = (35500 - 32500)/(6500/√15) = 1.79

We would determine the p value using the t test calculator. It becomes

p = 0.095

Assuming alpha = 0.05

Since alpha, 0.05 < than the p value, 0.095, then we would fail to reject the null hypothesis.

Do any of you know how to easily and properly convert a mixed fraction to a decimal?​
arlik [135]

Answer:

Here's a 2 step conversion.

Step-by-step explanation:

1. Convert the fraction to a decimal: Divide the numerator by the denominator

2. Add this decimal number to the whole number part of the mixed number

A mixed number is a whole number plus a fraction. To find the decimal form of a fraction just divide the numerator by the denominator using a calculator or long division. Then add the decimal number to the whole number.

Example: Convert the mixed number 7 1/4 to a decimal

Convert the fraction to a decimal: Divide 1 by 4

1 ÷ 4 = 0.25

Add 0.25 to the whole number 7:

7 + 0.25 = 7.25

Find the area of a regular hexagon with the given measurement. 48-inch perimeter A = sq. in. the answer is a square root
svp [43]

The area of a regular hexagon is

... A = (3√3)/2×s² . . . . . where s is the side length

Of course, the 6-sided figure will have a side length that is 1/6 of the perimeter.

... s = (48 in)/6 = 8 in

... A = (3√3)/2×(8 in)² = 96√3 in² . . . area of your regular hexagon
