Answer:
d
Step-by-step explanation:
from usatestprep:
The situation is not an example of uniform probability because freshmen, sophomores, juniors, and seniors do not have equal probabilities of being selected.; Uniform probability → equal probability of being selected
P(freshman) =
8/
26
; P(sophomore) =
7
/
26
; P(junior) =
6

26
; P(senior) =
5

26
; unequal probabilities → not uniform
2 3/8 - 1/4 = 2 1/8 x 1/8 = 17/64.
To do this, you first need to do the problem in the (). You have to turn 1/4 with a denominator of eight, so the fraction becomes 2/8. 2 3/8 - 2/8 = 2 1/8. Now we have to turn 2 1/8 into an improper fraction by doing whole number x denominator + numerator. 17/8 x 1/8 = 17/64.
You will lose money. Because $50 to make subtract $45 to sell (50-45) leaves you losing $5.
Well they both have integers in it there the same thing except your adding and subtracting. <span>Subtraction is the same thing as adding the opposite of the number. </span>
First term (a) = -15
common difference(d)= -9-(-15)
= -9+15=6
So,
12th term(a12)= a +(n-1)d
= -15+(12-1)×6
= -15 + 11×6
= -15+66
= 51
