Answer:

$1,824 \: {in}^{2}$

Step-by-step explanation:

Area of the figure = Area of rectangle with dimensions 48 in and 32 in + Area of triangle with base 48 in and height 12 in.

$= 48 \times 32 + \frac{1}{2} \times 48 \times 12 \\ \\ = 1,536 + 24 \times 12 \\ \\ = 1,536 + 288 \\ \\ = 1,824 \: {in}^{2}$

Answer:

The right answer is " $0.2$ ".

Step-by-step explanation:

The given values are:

$\bar{x_0} = 3.7$

$s_o=4.95$

$t_{\frac{0.05}{2} }=2.2621$

As we know,

95% confidence for $\mu_0$ will be:

= $\bar{x_0} \pm t_{\frac{0.05}{2} },n-1\times \frac{s_o}{\sqrt{n} }$

The lower bound will be:

= $3.7-2.2621\times \frac{4.95}{\sqrt{10} }$

= $0.16\simeq 0.2$

The upper bound will be:

= $3.7+2.2621\times \frac{4.95}{\sqrt{10} }$

= $7.23\simeq7.2$

Thus the right answer is " $0.2$ "
