Answer: 0.80
<u>Step-by-step explanation:</u>
P (2 ≤ x ≤ 4) is: P(X = 2) + P(X = 3) + P(X = 4)
= 0.36 + 0.12 + 0.32
= 0.48 + 0.32
= 0.80
It can also be calculated as: 1 - P(X = 1)
= 1 - 0.20
= 0.80
Answer:
f(2) =1
Step-by-step explanation:
f(2) is the y value of the graph when x =2
When x=2, y=1
so f(2) =1
Answer:
9.22
Step-by-step explanation:
6x6 + 7x7 = c^2
36 + 49 = c^2
85 = c^2
c = √85
c = 9.22
