Answer:
D
Step-by-step explanation:
The x-values are evenly-spaced, so any linear function table will have constant differences between the y-values. Here are the y-differences for the different options:
A 1, 2, 4
B 1, -1, 3
C -1, -2, 1
D 5, 5, 5 . . . . this represents a linear function
Answer:
The probability the student studies Art and
Biology is 0.2143.
Step-by-step explanation:
Denote the events as follows:
A = a students studies Art
B= a students studies Biology
The information provided is:
N = 42
n (An B) = 9
n (A' n B) = 10
n (A' n B') =7
Then the number of students who study Art
but not Biology is:
n(An B') = N -n (An B) -n (A' nB) - n (A'n B')
= 42 - 10 - 7 - 9
= 16
The number of students who study Art but
not Biology is 16.
Compute the probability the student studies
Art and Biology as follows:
P(ANB)
n(ANB)
= 0.2143
Thus, the probability the student studies Art
and Biology is 0.2143.
The answer is 45. there are 5 sides. each one is 9cm. 9*5= 45.
hope this helps.
