1. -7(6v+4)+3v(v+3)
-42v-28+3v ²+9v
-33v-28+3v ²
=3v ²-33v-28

2. -3k(2k-3)+7(k-7)

Answer:

The number of weeks required = 216 weeks

Step-by-step explanation:

Given that:

Margin of Error E = 200

Confidence interval = 95% = 0.95

Level of SIgnificance = 1 - C.I

= 1 - 0.95

= 0.05

Standard deviation = 1500

The Critical value for Z :

$Z_{\alpha/2} =Z_{0.05/2} \\ \\ = Z_{0.025} = 1.96$

The number of weeks( i.e the sample size (n) ) required is :

$n = (\dfrac{Z_{\alpha/2} \times \sigma}{E})^2$

$n = (\dfrac{1.96 \times 1500}{200})^2$

$n = (14.7)^2$

n = 216.09

n ≅ 216 weeks
