Answer:
The probability of selecting a worker who earns more than $ 6.75 is 0.2877 or 28.77%
Step-by-step explanation:
We are given;
The wages are normally distributed;
Average wage per hour; μ = $6.50
Standard deviation; σ = $0.45
Now, we want to find the probability that the worker earns more than $6.75
So, we'll find the z-value of P(x > 6.75) using the formula Z = (x-μ)/σ
Thus,
Z = (6.75-6.50)/0.45
Z = 0.556
So, looking at the z-distribution table P(Z>0.556) = 1 - P(Z < 0.556) = 1 - 0.7123 = 0.2877
Thus, The probability of selecting a worker who earns more than $ 6.75 is 0.2877 or 28.7%
Ted has to read a book that is 1000 pages long
he read 100 pages on Tuesday
On Wednesday, He read twice the number of pages that he read on Tuesday
on Thursday he read 396 pages
how many more pages does he have to read?
so the solution would be 1000- (100+2(100)+396)=x find x
Answer:
22, 50, 106, 218
Step-by-step explanation:
Using the recursive formula with f(0) = 8
Substitute n = 1, 2, 3, 4 into the recursive formula and evaluate
f(1) = 2f(1-1) + 6 = 2f(0) + 6 = (2 × 8) + 6 = 16 + 6 = 22
f(2) = 2f(1) + 6 = (2 ×× 22) + 6 = 44 + 6 = 50
f(3) = 2f(2) + 6 = (2 × 50) + 6 = 100 + 6 = 106
f(4) = 2f(3) + 6 = (2 × 106) + 6 = 212 + 6 = 218
