C)
Step-by-step explanation:
Given:
Number of freshmen = 3
Number of sophomores =3
Number of juniors =3
Number of seniors = 3
The team's captain is randomly selected from any grade level.
To find the the probability that a freshman will not be selected as captain.
Solution:
Total number of members in the team = = 12
Probability that a freshman will be selected as captain will be:
⇒
⇒
Reducing to simple fraction by dividing numerator and denominator by 3.
⇒
⇒
Thus, probability that a freshman will not be selected as captain will be given as:
⇒
Taking LCD.
⇒
Subtracting the numerators.
⇒ (Answer)
1. Volume of the sphere
Choice c
2. Algebra making a token effort to pretend to be geometry. Complementary angles add to 90 degrees.
(x+1) + (x-3)=90
2x -2 = 90
2x = 92
x = 46
Angles x+1=47 and x-3=43
Choice b
3. midpoint A=-5, E=5
The midpoint is just the average of A and E, here zero, point D
choice b
4. I can't really tell if x is supposed to be an angle or a length in this figure; presumably a length. I suppose we're to assume parallel lines; so this makes similar shapes, i.e. a proportionality:
Choice a
The length of the other leg is 40 millimeters.
