Answer:
C
Step-by-step explanation:
Definition: Two events, A and B, are independent if the fact that A occurs does not affect the probability of B occurring.
Event A = getting a 4 on the first roll.
Event B = getting a 4 on the second roll.
True option C: A and B are independent events, because the probability of the first roll will not affect the probability of the second roll.
Answer:
C. Yes Devon should have evaluated f(3).
Step-by-step explanation:
She substituted the wrong value. For x - 3 to be a factor f(3) must equal 0.
f(3) = 3^3 + 3^2 - 10(3) + 8 = 27 + 9 - 30 + 8
= 14, so x- 3 is not a factor anyway but she did substitute the wrong value.
Answer:
x=75
Step-by-step explanation:
74 = x-1
+1 +1
75=x
Answer:
E
Step-by-step explanation:
i guess the dotted lines outline a square
so get the area of the square which is 6×6=36
then don't focus on the shaded part but unshaded you'll see two right angled triangles
you will get a total for both as 21
then get the area of the square 36-21=15
so the area becomes 15
Answer:
The answer is b=18/z
Step-by-step explanation:
Let's solve for b.
bz/2=9
Step 1: Divide both sides by z/2.
1/2bz/z/2=9/z/2
b=18/z
Answer:
b=18/z
