Answer:
-1/6(-a+1)
Step-by-step explanation:
1. Factor out -1/6 from the expression: -1/6(4a-5a+1)
2. Collect the terms: -1/6(-a+1)
Final Answer: -1/6(-a+1)
Answer:
let m be minutes, p be pages
pages read = times(in minutes) * reading speed(pages per minutes)
p=m*(60/20)
p=3m
For every increase of a minute of reading time, pages that Wesly have read will increase by 3

Answer:
a) 8*88*10⁻⁶ ( 0.00088 %)
b) 0.2137 (21.37%)
Step-by-step explanation:
if the test contains 25 questions and each questions is independent of the others, then the random variable X= answer "x" questions correctly , has a binomial probability distribution. Then
P(X=x)= n!/((n-x)!*x!)*p^x*(1-p)^(n-x)
where
n= total number of questions= 25
p= probability of getting a question right = 1/4
then
a) P(x=n) = p^n = (1/4)²⁵ = 8*88*10⁻⁶ ( 0.00088 %)
b) P(x<5)= F(5)
where F(x) is the cumulative binomial probability distribution- Then from tables
P(x<5)= F(5)= 0.2137 (21.37%)
