<h3>Answer: The fraction 1/6</h3>

This is approximately equal to 0.167

====================================================

Explanation:

A = event of getting either a 1 or 2

P(A) = probability event A occurs

P(A) = 2/6 = 1/3, since there are two ways to get "1 or 2" out of six total

B = landing on heads

P(B) = 1/2, there are two sides and only one is heads

P(A and B) = probability getting a 1 or 2 and flipping heads on a coin

P(A and B) = P(A)*P(B) .... only possible if A and B are independent

P(A and B) = (1/3)*(1/2)

P(A and B) = (1*1)/(3*2)

P(A and B) = 1/6

Expand (x^2-3/2)^9 using binomial process

BaLLatris [955]

Use the Binomial expansion theorem to find and simplify each term.

$x^{18} - \frac{ 27x^{6} }{2}+ 81x^{14}- \frac{ 567x^{12} }{2}+ \frac{ 5103x^{10} }{16}- \frac{ 15309x^{8} }{16}+ \frac{ 15309x^{6} }{16} - \frac{ 59049x^{2} }{256}-$ $\frac{19683}{512}$

Man that was a lot to type out, hopefully i helped, and Gosh I hope I get a brainly for all that freaking typing. hehe~ ^.^

Nikita's distance from her for the second part of the race was 1.5 kilometers.

Since Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour) without training beforehand, and in the first part of the race, her average speed was 8.75 kilometers per hour, while for the second part of the race, she started to get tired, so her average speed dropped to 6 kilometers per hour, to determine which expression represents Nikita's distance for the second part of the race the following calculation must be performed:

8.75 x 0.65 + 6 x 0 = 5.68
8.75 x 0.50 + 6 x 0.15 = 5.275
8.75 x 0.40 + 6 x 0.25 = 5
100 = 60
40 = X
40 x 60/100 = X
24 = X
39 - 24 = 15
15 = 1/4 hour
6/4 = 1.5

Therefore, Nikita's distance from her for the second part of the race was 1.5 kilometers.
