Answer:
$ 8.72
Step-by-step explanation:
- How much does Joe make per hour now?
$8.15 + 7%·$8.15 =
= $8.15 + 7×8.15/100
= $8.15 + $57.05/100
= $8.15 + $0.57
= $ 8.72

Answer:
The range of the 95% data (X) = 238.3 days < X < 289.9 days
Step-by-step explanation:
Given;
mean of the normal distribution, m = 264.1 days
standard deviation, d = 12.9 days
between two standard deviation below and above the mean is 96% of all the data.
two standard deviation below the mean = m - 2d
= 264.1 - 2(12.9)
= 238.3 days
two standard deviation above the mean = m + 2d
= 264.1 + 2(12.9)
= 289.9 days
The middle of the 95% of most pregnancies would be found in the following range;
238.3 days < X < 289.9 days
Answer:
Erich planted 7 seeds ...
he had to remove 17 plants ....
he expected to have less or equal 46 plants ...
Step-by-step explanation:
Look at keywords like remove ~ => which indicates that something is being subtracted
Since x represents seed packets, and the amount he planted is a number multiplied by x, we can deduce he planted 7 seeds ( 7 * x)
1 step (B): raise both sides of the equation to the power of 2.
.
2 step (A): simplify to obtain the final radical term on one side of the equation.
.
3 step (F): raise both sides of the equation to the power of 2 again.
.
4 step (E): simplify to get a quadratic equation.
.
5 step (D): use the quadratic formula to find the values of x.
.
6 step (C): apply the zero product rule.
.
Additional 7 step: check these solutions, substituting into the initial equation.
