One of the wagers in the game of roulette is to place a bet that the ball will land on a black number. (Eighteen of the numbers

are black, 18 are red, and two are green.) If the ball lands on a black number, the player wins the amount of his bet. If a player bets $1, find the player's expectation. (Round your answer to two decimal places.)

Vance used the associative property to write (4.5m+7/8)-9 as the equivalent expression 4.5(7/8-9). Did Vance apply the associati
baherus [9]
Answer: the fourth choice: <span>No, the addition symbol was dropped in the second expression

Justification:

1) The right operation is: </span><span>(4.5m + 7/8) - 9 </span><span>= 4.5m + (7/8 - 9), this is you have to keep the + operator, since you are just grouping the terms in an alternate form.

2) Droping the + operator leads incorrectly to the multiplication of the first term, 4.5m to the terms in parenthesis, instead to the addition, which is what corresponds.

If 10% of men are bald, what is the probability that fewer than 100 in a random sample of 818 men are bald? (Answers must be in
Greeley [361]

Answer: the probability that fewer than 100 in a random sample of 818 men are bald is 0.9830

Step-by-step explanation:

Given that;

p = 10% = 0.1

so let q = 1 - p = 1 - 0.1 = 0.9

n = 818

μ = np = 818 × 0.1 = 81.8

α = √(npq) = √( 818 × 0.1 × 0.9 ) = √73.62 = 8.58

Now to find P( x < 100)

we say;

Z = (X-μ / α) = ((100-81.8) / 8.58) = 18.2 / 8.58 = 2.12

P(x<100) = P(z < 2.12)

from z-score table

P(z < 2.12) = 0.9830

Therefore the probability that fewer than 100 in a random sample of 818 men are bald is 0.9830
