Answer:
x=-30
Step-by-step explanation:
x+34=4
-34 -34
x=-30
Say she chooses topic A. She needs at least one book to arrive on time. The probability that no books arrive on time is 0.1 x 0.1 = 0.01 so the probability that at least one book arrives on time is 1 - 0.01 = 0.99.
Say she chooses topic B. She needs at least two books to arrive on time. The probability of no books arriving on time is 0.1 x 0.1 x 0.1 x 0.1 = 0.0001. The probability of exactly one book arriving on time is 4 x 0.1 x 0.1 x 0.1 x 0.9 = 0.0036 (binomial probability distribution formula - the 4 comes from 4C1). So the probability of her not getting enough books is 0.0001 + 0.0036 = 0.0037 and the probability she does get the books she needs on time is 1 - 0.0037 = 0.9963.
So she should choose topic B.
Answer:
the equation is - 
Explanation:
Given -
We have to find a line passing through the point 
nd parallel to the given line.
Find the slope of the given line.
It is the coefficeint of 
m₁ = 1
The two lines are parallel. Hence
m₂=m₁=1 Where m₂is the slope of the second line.
You have slope and the points
Find the Y intercept
Y-Intercept 
and slope m₂=1
Fix the equation
Answer:
7
Step-by-step explanation:
f(x) = x+2
The input is x=5
The output would be
f(x) = 5+2 = 7
