Answer: 0.1061
Step-by-step explanation:
Given : An insurance company found that 9% of drivers were involved in a car accident last year.
Thus, the probability of drivers involved in car accident last year = 0.09
The formula of binomial distribution :-
If seven (n=7) drivers are randomly selected then , the probability that exactly two (x=2) of them were involved in a car accident last year is given by :-
Hence, the required probability :-0.1061
Answer:
<h3>0.2</h3>
Step-by-step explanation:
Given a linear function f(x) that varies at a constant rate of change 1.5 with respect to x, If x varies from x = 1.3 to x = 1.5, the to get the amount by which x change by, we will use the expression;
Δx = x₂-x₁
x₂ is the final value of x
x₁ is the initial value of x
Given x₁ = 1.3 and x₂ = 1.5
Substitute the values in the formula above;
Δx = x₂-x₁
Δx = 1.5 - 1.3
Δx = 0.2
Hence the value of x change by 0.2
Answer:
Step-by-step explanation:
Y=18.75x + 2500
Change the addition sign to a subtraction = Y=18.75x - 2500
Then bring 18.75x and divide it by 2500 = 133.33 so Y=133.33 if you were to round it would be 133.00
