Answer:
$405.60
Step-by-step explanation:
If Isaac works for 40 hours will earn $8.45×40=$388. Since he worked 4 extra hours, he will earn $8.45×2×4 since he worked 4 extra hours. $8.45×2=$16.90, which is the amount he earns for every extra hour he works. $16.90×4=$67.60. Now if we add $67.60+$388=$405.60.
Hope this helps!
Answer:
7846
Step-by-step explanation:
two 'minus' signs cancel each other out and become an 'plus' sign
therefore
7512-(-334) = 7512 + 334
= 7846
I don't know why you wrote ' write your answer as a 'mixed number ' in 'simplest form'. A mixed number can only be formed when you have a fraction, an improper fraction no less, the answer is a whole number, and therefore cannot be written as a mixed number in simplest form. If I am wrong pls let me know and elaborate by what you mean by 'mixed number' in the comments.
I believe it may be a trick question, but who knows.
Examples of fractions expressed as a mixed number.
19/8 = 2 3/8
17/5 = 3 2/5
By assuming the standard deviation of population 2.2 the confidence interval is 8.67 toys,8.94 toys.
Given sample size of 1492 children,99% confidence interval , sample mean of 8.8, population standard deviation=2.2.
This type of problems can be solved through z test and in z test we have to first find the z score and then p value from normal distribution table.
First we have to find the value of α which can be calculated as under:
α=(1-0.99)/2=0.005
p=1-0.005=0.995
corresponding z value will be 2.575 for p=0.995 .
Margin of error=z*x/d
where x is mean and d is standard deviation.
M=2.575*2.2/
=0.14
So the lower value will be x-M
=8.8-0.14
=8.66
=8.67 ( after rounding)
The upper value will be x+M
=8.8+0.14
=8.94
Hence the confidence interval will be 8.67 toys and 8.94 toys.

Answer:
How to Graph a Linear Inequality
First, graph the "equals" line, then shade in the correct area.
There are three steps:
1.) Rearrange the equation so "y" is on the left and everything else on the right.
2.) Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
4.) Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
Hope This Helps! Have A Nice Day!!
About 3.7 inches. Look at the 12 on the x axis because that is one year and see where it hits the line
