Answer:

2916 square inches

Step-by-step explanation:

Surface area of rectangular prism:

Here, area of the top of the prism is not included.

l = 24 in ; b = 20 in ; h = 16 in

Surface area = lb + 2bh + 2lh

= 24 * 20 + 2*20*16 + 2*24 *16

= 480 + 640 + 768

= 1888 sqaure inches

Surface area of triangular prism:

length = 24 in ; a = b = 16 in ; base = 20 in and height = 13 in

$\sf \text{Base area=$2*\dfrac{1}{2}*base *height = base *height$}$

= 20 * 13

= 260 square inches

Surface area = length*(a +b) + base area

= 24*(16+16) + 260

= 24 * 32 + 260

= 768 + 260

= 1028 square inches

Surface area of composite figure = 1888 + 1028

= 2916 square inches

vovangra [49]

Answer:

$ $4f$

Step-by-step explanation:

Let's assume $f$ represents the number of pounds of fruit.

We need to multiply the number of pounds of fruit by the cost per pound.

This is $ $f * 4$ , or in a simpler form, $ $4f$ .

83 random samples were selected from a normally distributed population and were found to have a mean of 32.1 and a standard devi

arlik [135]

Answer:

$\frac{(82)(2.4)^2}{104.139} \leq \sigma^2 \leq \frac{(82)(2.4)^2}{62.132}$

$4.525 \leq \sigma^2 \leq 7.602$

Now we just take square root on both sides of the interval and we got:

$2.127 \leq \sigma \leq 2.757$

Step-by-step explanation:

Information given

$\bar X=32.1$ represent the sample mean

$\mu$ population mean (variable of interest)

s=2.4 represent the sample standard deviation

n=83 represent the sample size

Confidence interval

The confidence interval for the population variance is given by the following formula:

$\frac{(n-1)s^2}{\chi^2_{\alpha/2}} \leq \sigma^2 \leq \frac{(n-1)s^2}{\chi^2_{1-\alpha/2}}$

The degrees of freedom given by:

$df=n-1=8-1=7$

The confidence level is 0.90 or 90%, the value of $\alpha=0.1$ and $\alpha/2 =0.05$ , and we can use excel, a calculator or a table to find the critical values.

The excel commands would be: "=CHISQ.INV(0.05,82)" "=CHISQ.INV(0.95,82)". so for this case the critical values are:

$\chi^2_{\alpha/2}=104.139$

$\chi^2_{1- \alpha/2}=62.132$

The confidence interval is given by:

$\frac{(82)(2.4)^2}{104.139} \leq \sigma^2 \leq \frac{(82)(2.4)^2}{62.132}$

$4.525 \leq \sigma^2 \leq 7.602$

Now we just take square root on both sides of the interval and we got:

$2.127 \leq \sigma \leq 2.757$

Find the value of x..........

Leviafan [203]

Answer:

x = 53.5

Step-by-step explanation:

x is one half the difference of the intercepted arcs, that is

x = 0.5(137 - 30) = 0.5 × 107 = 53.5
