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
This is false. An arbitrary number is the same as a random number. It is any number that is not specified, not restricted and not consciously thought of. Simply put, an arbitrary number or a random number is any number that you can think of.
Answer: 127 cookies
Step-by-step explanation:
1. If you look back to the text you will see that 12 is 1 in 1:3:4 and you multiply that by 2. 12 * 2 = 24.
2. Divide 24 by 3 and that gives you 8 than times it by 5 for it to give you 40
3. Divide 36 by 4 and that equals to 9 than multiply it by 7 which that gives you 63
4. Add 24, 40, and 63 for it to give you 127
Thank you for following these steps if it is correct and this is my first time so if I am incorrect I will look upon my mistake and correct and help many of you people who need help
Answer:
C. 5
Step-by-step explanation:
first expression 5 × (9-3) = 30
second one 45 - 3x
to make it 30 = 30
x should be = 5
