Anni [7]

<h3>Solution</h3>

1.8 × 10⁴

= 18 × 10³

= 180 × 10²

= 1800 × 10

= 18000

The data on the right represent the number of traffic fatalities by seat location and gender. Determine P() and P(|). Are t

liubo4ka [24]

Answer:

The probability of selecting a male is 0.3151.

The events "male" and "driver" are not independent.

The correct option is B.

Step-by-step explanation:

The missing data is as follows:

Female Male Total

Driver 32759 11715 44474

Passenger 6534 6361 12895

Total 39293 18076 57369

The complete question is:

Determine P(male) and P(male|driver). Are the events "male" and "driver" independent?

Solution:

Compute the probability of selecting a male as follow:

$P(M)=\frac{n(M)}{N}=\frac{18076 }{57369}=0.3151$

Thus, the probability of selecting a male is 0.3151.

Compute the probability of selecting a male given that he is a driver as follows:

$P(M|D)=\frac{P(M\cap D)}{P(D)}=\frac{n(M\cap D)}{n(D)}=\frac{11715 }{44474}=0.2634$

Two events, say A and B, are independent if:

P (A|B) = P(A)

Here, P (M|D) ≠ P (M)

Thus, the events "male" and "driver" are not independent.

PLEASE HELP ILL MARK BRAINLIEST Simplify the expression. (a + 2b)3 – 3a

Wittaler [7]

Answer:

The answer is 6b

Step-by-step explanation:

1) Regroup terms.

$3(a + 2b) - 3a$

2) Expand by distributing terms.

$3a + 6b - 3a$

3) Collect like terms .

$(3a + 3a) + 6b$

4) Simplify.

$6b$

Therefor, the answer is 6b.

Fantom [35]

The formula is
A=p (1+r/k)^kt
A future value?
P present value 874
R interest rate 0.032
K compounded quarterly 4
T time 7 years
A=874×(1+0.032÷4)^(4×7)=1,092.46
