Answer:

C)78.5

Step-by-step explanation:

∠BOZ = X

∠WOB = 7X - 4

X + 7X -4 = 180     {STRAIGHT LINE }

8X = 180 + 4

8X = 184

X = 184/8

X = 23

∠WOB = 7X - 4 = 7*23 - 4 = 161 - 4 = 157

OA  bisects ∠WOB. So, ∠WOA =∠AOB

∠AOB = 1/2 of ∠WOB = 157/2 = 78.5

Find the perimeter of the figure to the nearest hundredth.<br><br><br> Ps: it is not 30
frutty [35]

Answer:

Perimeter = 36.8 ft

Step-by-step explanation:

<u>Step 1:  Add the straight sides together</u>

3+3+3+3+3+3 = 18 ft

<u>Step 2:  Find the perimeter of the semi-circles</u>

The formula for the perimeter of semi-circle:  1/2 π × d

Diameter = 12 - 3 - 3 = 6, because the whole length is 12 minus the 6 ft of other stuff.

Now, 1/2π * 6 = 9.4 ft

But, there are two semi-circles so it will be 9.4 + 9.4 = 18.8 ft

<u>Step 3:  Add all of them</u>

18 + 18.8 = 36.8 ft

M+1 3/8=5 What does m equal?
Arte-miy333 [17]

\text{ The value of m is equal to 3.625 or }\frac{29}{8} \text{ or } 3\frac{5}{8}

<em><u>Solution:</u></em>

Given that we have to find the value of "m"

Given expression is:

m + 1\frac{3}{8} = 5

<em><u>Let us first convert the mixed fraction to improper fraction</u></em>

Steps to follow:

Divide the numerator by the denominator.

Write down the whole number answer.

Then write down any remainder above the denominator.

Therefore,

1\frac{3}{8}=\frac{8 \times 1+3}{8} = \frac{8+3}{8} = \frac{11}{8}

Now the expression becomes,

m + \frac{11}{8} = 5

Keep the variable "m" on L.H.S and move the constant to R.H.S

m = 5 - \frac{11}{8}\\\\m = \frac{5 \times 8 -11}{8}\\\\m = \frac{40-11}{8}\\\\m = \frac{29}{8}\\\\\text{In mixed fractions, we can write as }\\\\m = \frac{29}{8} = 3\frac{5}{8}

Thus value of m is equal to 3.625 or \frac{29}{8} \text{ or } 3\frac{5}{8}

What is a 96% confidence interval for the proportion of weight-lifting injuries in this age group that were accidental?
loris [4]
<span>A 96% confidence interval means that 96% of the time you can believe that the result will fall into a range of numbers. In the case of weight lifting this would mean that 96% of the time, the proportion of weight-lifting injuries were accidental would fall in between the two parameters set forth.</span>
