Answer:

? = 5.12

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin B = opp/ hyp

sin 65= 5/ ?

? = 5/ sin 65

? =5.516889595

To the nearest hundredth

? = 5.12

Airplane at 19,200 feet descending at a rate of 40 feet per second. Another airplane takes off and ascends at a rate of 60 feet

AleksandrR [38]

Answer:

Step-by-step explanation:

Let t = flying time in seconds for each plane

Descending rate = 40 ft/s

Ascending rate = 60 ft/s

Descending height, hd= 19200 - 40t

Ascending height, ha = 60t

Equating hd = ha, therefore:

60t = 19200-40t

60t + 40t = 19200

100t = 19200

t = 19200/100

t = 192 seconds

h = 19200 - 192(40)

h = 19200 - 7680

= 11,520 ft.

James Desreumaux, VP of Human Resources of American First Banks (AFB), is reviewing the employee training programs of AFB banks.

BartSMP [9]

Answer: (24.02,25.98)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given : Sample size : n= 100

Sample mean : $\overline{x}=25\text{ hours}$

Standard deviation : $\sigma=5\text{ hours}$

Significance level : $\alpha: 1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

The confidence interval for population mean is given by :-

$\overline{x}\pm\ z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=25\pm(1.96)\dfrac{5}{\sqrt{100}}\\\\=25\pm0.98\\\\=(25-0.98,\ 25+0.98)=(24.02,25.98)$

Hence, the 95% confidence interval for the population mean of training times is (24.02, 25.98).

A movie theater sells 3 sizes of popcorn as described in the table. Small=$2 Medium=$3 Large=$4 a.)Write a polynomial with 3 ter

nevsk [136]

To answer this item, we let the number of small, medium, and large popcorns sold be equal to x, y, and z such that the total amount that can be obtained from the sales is,
2x + 3y + 4z = total sales
If the 9p is the total number of popcorns sold, the equation is,
x + y + z = 9p
