Step-by-step explanation:

That triangle in the corner is an right angle isosceles triangle as that line the midpoint of both sides :

the base angle of this triangle (x) will be :

180 = 90 + 2x

90 = 2x

x= 45

Angles on a straight line add up to 180. So to work out a :

180 = 45 + a

135 = a

Hope this helped and brainliest please

Nitella [24]

Answer:

651 is the minimum number of people over age 30 they must include in their sample.        

Step-by-step explanation:

We are given the following information:

Confidence level = 90%

Significance level = 10%

Maximum error = 0.09

Variance = 1.96

\text{Standard Deviation} = \sqrt{\text{Variance}} = \sqrt{1.96} = 1.4

Formula:

\text{Error} = z_{critical}\dfrac{\sigma}{\sqrt{n}}

Putting all the values,

z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.64

0.09 = 1.64\times \dfrac{1.4}{\sqrt{n}}\\\\n = (\dfrac{1.64\times 1.4}{0.09})^2 = 650.81 \approx 651

651 is the minimum number of people over age 30 they must include in their sample.
