Answer:

102cm²

Step-by-step explanation:

Surface Area = BH +Lp

B is the base area

H is the height of the Prism

L is the slant height

p is t perimeter of its base

B =1/2 ×3×4

B= 6cm²

H = 7cm

L = 5cm

P = 3cm+4cm+5cm

P = 12cm

Substitute

TSA = 6(7)+5(12)

TSA = 42+60

TSA = 102cm²

Hence the total surface area of the shape is 102cm²

coldgirl [10]

Answer:

The sample size required is 2500.

Step-by-step explanation:

z-score:

In function of the margin of error M, the z-score is given by:

$Z = \frac{M}{\frac{\sigma}{\sqrt{n}}} = \frac{M\sqrt{n}}{\sigma}$

In this question, we have that:

$\sigma = 51.02, M = 2, Z = 1.96$

$Z = \frac{M\sqrt{n}}{\sigma}$

$1.96 = \frac{2\sqrt{n}}{51.02}$

$2\sqrt{n} = 51.02*1.96$

$\sqrt{n} = \frac{51.02*1.96}{2}$

$(\sqrt{n})^2 = (\frac{51.02*1.96}{2})^2$

$n = 2500$

The sample size required is 2500.
