Liz wants to estimate the percentage of people who rent their home. She surveys 320 individuals and finds that 176 rent their ho
SOVA2 [1]

Answer: 0.065

Step-by-step explanation:

Given : Sample size : n= 320

The sample proportion of people who rent their home : p=\dfrac{176}{320}=0.55

Significance level : \alpha:1-0.98=0.02

Then , Critical value : z_{\alpha/2}=2.33

The formula to find the margin of error : -

E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}\\\\\Rightarrow\ E=(2.33)\sqrt{\dfrac{0.55(1-0.55)}{320}}\\\\\Rightarrow\ E=0.064799034281\approx0.065

Hence, the margin of error for the confidence interval for the population proportion with a 98% confidence level =0.065

What is the perimeter of this shape?
Korvikt [17]

Answer:

59.4 km

Step-by-step explanation:

First you need to find the circumference of the circle. 20*3.14=62.8. Then, you divide this by two, because there is only half of a circle, to get 31.4.

Then you can just add 16 + 12 + 31.4 to get 59.4.

Veseljchak [2.6K]

Answer:

Step-by-step explanation:

First we know triangle WXY is an equilateral which means all its angles are 60 degrees.

Next we know triangle WZY is an isosceles so it has 2 angles that are equal to each other.  

Since angle Z is an obtuse angle. We can calculate the other angles which we will assume are equal because 138+138 is greater than 180 degrees.

180-138 = 42                

42/2 = 21              <-- divide by 2 because we know we're looking for 2 angles

For the angles of WXY.

60-21 = 39

Therefore

Angle I = 60

Angle 2 = 39

Angle 3 = 21

Angle 4 = 39

Angle 5 = 21
