Lemur [1.5K]

SOLUTION

We will use the formula

$\begin{gathered} Z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}} \\ where\text{ } \\ x=51.3,\mu=50,\sigma=6,n=40 \end{gathered}$

Applying we have

$\begin{gathered} Z=\frac{51.3-50}{\frac{6}{\sqrt{40}}} \\ Z=\frac{1.3}{\frac{6}{\sqrt{40}}} \\ Z=1.37032 \end{gathered}$

Now using a Zscore calculator for 1.370320, we have

storchak [24]

Answer:

Surface area = 85.84 ft²

Step-by-step explanation:

Considering the fact that large rectangle area = 6 x 12 = 72 ft²

Also, the two triangles area => 2(0.5 * base * height) = 2(4 x 3.46 x 0.5) = 13.84 ft²

Hence, the total surface area is

72 + 13.84 = 85.84 ft²

Therefore, the surface area of the fabric is 85.84ft²
