Answer:

x = 8.4

Step-by-step explanation:

The area of a rectangle is equal to the length times the width.

126 = 5x * 3x

126 = 15x

8.4 = x

Since the side length of the square is equal to x, it is equal to 8.4.

Meh need some help.Question 2 of 8

jeka94

I am a little confused about the question you are trying to ask. It is an isosceles triangle because it has two sides of equal length.

The other angle would be...
180-2(55)=70 degrees

Answer:

The confidence interval is -5.3444 to 6.453 .

Step-by-step explanation:

We are given that In a survey of 458 likely voters, 254 said that they would vote "yes" on the referendum.

So, n = 458

x = 254

We will use sample proportion over here

$\widehat{p}=\frac{x}{n}$

$\widehat{p}=\frac{254}{458}$

$\widehat{p}=0.5545$

Confidence level = 95% = 0.95

Level of significance = 1-0.95 = 0.05

z value at 0.05 significance level = 1.96

Formula of confidence interval : $\widehat{p}-x\times \sqrt{\frac{\widehat{p} \times (1-\widehat{p})}{n}$ to $\widehat{p}+x\times \sqrt{\frac{\widehat{p} \times (1-\widehat{p})}{n}$
