Answer:
58%
Step-by-step explanation:
Out of 60 students who take math, 35 of them will also have science. The desired probability is ...
35/60 = 0.58333... ≈ 58%
__
More formally, ...
P(S | M) = P(S&M)/P(M)
= 35%/60% = 7/12 ≈ 58%

Answer:
Step-by-step explanation:
because you are finding the total they both had in September, you add. 12 + 9 = 21
Answer: a) reflected over x-axis and reflected over y-axis
<u>Step-by-step explanation:</u>
Reflection over the x-axis changes the sign of the y-coordinate
Z = (x, y) → Z'(x, -y)
Reflection over the y-axis changes the sign of the x-coordinate
Z' = (x, -y) → Z''(-x, -y)
A = (-4, 1) → A'' = (4, -1)
B = (-3, 2) → A'' = (3, -2)
C = (-1, 2) → A'' = (1, -2)
D = (-2, 1) → A'' = (2, -1)
