Answer: You can divide a number by a fraction by flipping over the fraction and multiplying them together.
Step-by-step explanation:
For example:
Lets say we wanted to divide 8 by 3/4
8÷![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
Change the division symbol into multiplication, and flip over the fraction (a great way to remember doing this is to remember the phrase <em>Copy Dot Flip </em>- Copy the first digit as it is, put a dot for multiplication, and then flip the fraction over)
8 ·![\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D)
Now, just multiply and reduce/simplify the fraction if needed
<u>Final answer is </u>
<u>, no need to simplify or reduce</u>

Answer:
: The average time postal employees have worked for the postal service is 7 years.
: The average time postal employees have worked for the postal service is not 7 years.
Step-by-step explanation:
We need to know the significance level to decide if the average time worked for the postal service has changed according to the the random sample of 100 postal employees working time.
Aur hypothesis would use two tailed critical region, sice the hypothesis is an equality.

Answer:
60 inches
Step-by-step explanation:
Fill in the given numbers and solve for length. Then convert to inches.
18 ft = 2L +2(4 ft)
10 ft = 2L . . . . . . . . subtract 8 ft
5 ft = L = 5×(12 in) = 60 in
The length of Sarah's back yard is 60 inches.
Given:
Line of the graph
To find:
Equation of the line
Solution:
Take any two points on the graph of the line.
Let the points are (0, 3) and (3, 0).
Slope of the line:
![$m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%24m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Here, ![x_1=0, y_1=3, x_2=3, y_2=0](https://tex.z-dn.net/?f=x_1%3D0%2C%20y_1%3D3%2C%20x_2%3D3%2C%20y_2%3D0)
![$m=\frac{0-3}{3-0}](https://tex.z-dn.net/?f=%24m%3D%5Cfrac%7B0-3%7D%7B3-0%7D)
![$m=\frac{-3}{3}](https://tex.z-dn.net/?f=%24m%3D%5Cfrac%7B-3%7D%7B3%7D)
m = -1
b = y-intercept
y-intercept of the graph is the point which x = 0.
y-intercept is 3 when x = 0.
⇒ b = 3
Equation of a line:
y = mx + b
y = -1(x) + 3
y = -x + 3
The equation of the line is y = -x + 3.
