Step-by-step explanation:
Answer:
A) 0.335; B) 0.343; C) 0.599
Step-by-step explanation:
For part A,
To find the probability that the user has more than one infection per year, we can either add together the probabilities for 2, 3, 4 and 5; or we can add together the probabilities for 0 and 1 and subtract them from 1:
1-(P(X = 0)+P(X = 1))
= 1-(0.343+0.322) = 1-0.665 = 0.335
For part B,
The probability that the user has no infections per year is P(X = 0); this is 0.343.
For part C,
The probability that the user has between 1 and 3 infections (inclusive) per year is
P(1 ≤ X ≤ 3) = 0.322+0.201+0.076 = 0.599
Answer:
135 degrees
Step-by-step explanation:
2π radians is the central angle of a full circle, so 2π radians is 360 degrees.
That means that π radians = 180 degrees.
3π/4 radians * (180 degrees)/(π radians) = 135 degrees
The expression is 9*
+2+
.
9*
+2+
---> First square
by squaring the top and bottom number.
=9*
+2+
---> Multiply 9 and
=1+2+
---> Add
=3
---> Optional: turn into improper fraction
