Aleks04 [339]

Answer:

The elevation to the top of the building from the point on the ground where the shopper is standing is = 17.35°

Step-by-step explanation:

From the ΔABC

AB = height of the building = 250 feet

BC = 800 ft

Angle of elevation = $\theta$

$\tan \theta = \frac{AB}{BC}$

$\tan \theta = \frac{250}{800}$

$\tan \theta$ = 0.3125

$\theta = 17.35$ °

Therefore the elevation to the top of the building from the point on the ground where the shopper is standing is = 17.35°

Solve this linear equation for p:<br> 2.6(5.5p – 12.4) = 127.92

Ymorist [56]

HI :)
First we must distribute the 2.6 to everything inside the ()

The new equation would then be
14.3p-32.24 = 127.92

Then you would add a -32.24 to each side of the equal sign, so that the 32.34 would become a zero pair on the right side of the equal sign and cancel.

The new equation would then be
14.3p = 160.16

Then you divide each side of the = by 14.3, that way the p becomes isolated.
14.3p/14.3 = 160.16/14.3

Then you're left with
p = 11.2

Hope this helped :)

slega [8]

A. How many different selections are possible?

B. What is the probability of winning?

C. If you win, what is your net profit?

D. Find the expected value

Answer :

A. sequence of three digits (from 0 to 9). so 10 numbers.

We know 3 lottery games. So possible selections = 10^3 = 1000

B. Probability of winning = one outcome / total outcomes

P( winning) = $\frac{1}{1000}$ = 0.001

c. Net profit = winning amount - paid amount

= 384.13 - 1.33 = $382.8

D. expected value

E(x) = net profit * winning probability - paid amount * lost probability

E(x) = 382.8 * 0.001 - 1.33 * 0.999 = -0.95

you expect to lose 95 cents per ticket.
