Answer:

∠ EAC = 50°

Step-by-step explanation:

Since AE is an angle bisector of ∠ BAC , then

∠ EAC = ∠ BAE , that is

3x - 10 = x + 30 ( subtract x from both sides )

2x - 10 = 30 ( add 10 to both sides )

2x = 40 ( divide both sides by 2 )

x = 20

Then

∠ EAC = 3x - 10 = 3(20) - 10 = 60 - 10 = 50°

Answer:

The answer is option D: the advertiser is bidding $0.70 between 9 pm-12 am on weeknights.

Step-by-step explanation:

The normal bid is $0.40 and the bid multiplier is 75%.

This amount becomes:

$0.40+(0.75\times0.40)$

= $0.70 (OPTION D)

So, the advertiser is bidding $0.70 between 9 pm-12 am on weeknights.

QUESTION 7.

Elan Coil [88]

The probability that exactly 4 of the selected adults believe in reincarnation is 5.184%, and the probability that all of the selected adults believe in reincarnation is 7.776%.

Given that based on a poll, 60% of adults believe in reincarnation, to determine, assuming that 5 adults are randomly selected, what is the probability that exactly 4 of the selected adults believe in reincarnation, and what is the probability that all of the selected adults believe in reincarnation, the following calculations must be performed:

0.6 x 0.6 x 0.6 x 0.6 x 0.4 = X
0.36 x 0.36 x 0.4 = X
0.1296 x 0.4 = X
0.05184 = X
0.05184 x 100 = 5.184

0.6 x 0.6 x 0.6 x 0.6 x 0.6 = X
0.36 x 0.36 x 0.6 = X
0.1296 x 0.6 = X
0.07776 = X
0.07776 x 100 = 7.776

Therefore, the probability that exactly 4 of the selected adults believe in reincarnation is 5.184%, and the probability that all of the selected adults believe in reincarnation is 7.776%.
