Answer: 10 + 7x 
40
We can use exclusion method:
A and C is not correct because Ms Hernandez doesn't want to spend more than 40 dollars --> so it must be less than or equal to 40
The answer is A. or B. because it states that both the central and inscribed angle have the same endpoints.
Answer:
30 and 3.4641
Step-by-step explanation:
The mean of a binomial distribution is:
μ = np
And the standard deviation of a binomial distribution is:
σ = √(npq)
Here, n = 50, p = 0.60, and q = 0.40.
μ = np = 50 × 0.60 = 30
σ = √(npq) = √(50 × 0.60 × 0.40) = 3.4641
P(t)=number of sheet of paper after t minutes.
p(t) will have to be equal to 0, wnen the printer use all 100 sheets of paper;
Therefore;
if p(t)=0
Then:
-8t+100=0
We solve this equation.
-8t+100=0
8t=100
t=100/8
t=12.5
Answer: the printer prints 100 sheets of paper in 12.5 minutes.
