$\begin{cases}y=x-6\\y=2x\end{cases}\implies~x-6=2x\implies~x=-6$

which means

$y=x-6=y=-6-6=-12$

tekilochka [14]

Answer:

a) 25

b) 49

c) 97

Step-by-step explanation:

The sample size is calculated using the formula, n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

Now,

for 95% confidence level value of z-factor = 1.96

Given:

Mean = $3.94

standard deviation = $0.25

thus,

a) for margin of error = $0.10

n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

n = $(\frac{0.25\times1.96}{\textup{0.10}})^2$

n = 4.9²

n = 24.01 ≈ 25 (Rounded off to next integer)

b) for margin of error = $0.07

n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

n = $(\frac{0.25\times1.96}{\textup{0.07}})^2$

n = 7²

n = 49

c) for margin of error = $0.05

n = $(\frac{\sigma\times z}{\textup{Margin of error}})^2$

n = $(\frac{0.25\times1.96}{\textup{0.05}})^2$

n = 9.8²

n = 96.04 ≈ 97 (Rounded off to next integer)
