Answer:

$\mathbf{Margin\; of\; error} =$ .0942816

Step-by-step explanation:

Given

Sample size n = 150

Sample proportion ${\widehat{(p)}$ = $\frac{42}{150}$ = 0.28

Confidence interval = $\frac{99}{100}$ = .99

$Margin\; of\; error = z_{\frac{\alpha }{2}}\sqrt{\frac{{\widehat{(p)}}{(1 - \widehat{p})}}{n}}$

$\alpha =$ 1 - confidence interval = 1 - 0.99 = .01

$margin\; of\; error = z_{\frac{.01 }{2}}\sqrt{\frac{(.28) (1 - 0.28)}{150}$

For 99 $\%$ confidence interval

( Z = 2.576 )

$margin\; of\; error = z_{.005 }}\sqrt{\frac{(.28) (1 - 0.28)}{150}$

$margin\; of\; error = 2.576\times\sqrt{\frac{(.28) (1 - 0.28)}{150}$

= .0942816

HELP WITH THIS QUESTION ASAP!!

matrenka [14]

Answer:

$7a^{2} +20$

Step-by-step explanation:

Given: Area of one cupboard= $3a^{2} -5y+15$

Area of second cupboard= $4a^{2} +5y+5$

As per question, carpenter need to determine the amount of plywood required for two cupboard.

Lets, add the area of two cupboard to know the amount of plywood required.

∴ $3a^{2} -5y+15$ - Area of first cupboard.

$4a^{2} +5y+5$ - Area of second cupboard.

Adding both the area;

$(3a^{2} -5y+15)+(4a^{2} +5y+5)$

Now, opening the parenthesis

$3a^{2} -5y+15+4a^{2} +5y+5$

we will get $7a^{2} +20$ .

∴ Total area of cupboard= $7a^{2} +20$
