Answer:
.
It means that 673 of 9 inch tiles are required to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.
Step-by-step explanation:
Given:
The function relating number of 9 inch tiles required and area to cover is:
Now, plug in 400 for to evaluate .
Therefore, Don required 673 of 9 inch tiles to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.
We need to put the data set in ascending order
1.2 4.3 5.0 5.8 6.2 6.3 7.2 7.4 8.4
Interquartile range is given by upper quartile - lower quartile
Location of lower quartile = 1/4 of the data set
Location of upper quartile = 3/4 of the data set
Lower quartile = 1/4 of 9 = 2.25th (rounded down to 2nd value) = 4.3
Upper quartile = 3/4 of 9 = 6.75th (rounded up to 7th value) = 7.2
Interquartile value = 7.2 - 4.3 = 2.9
Answer: C
Why?
5x+y= 17
You need to get the y alone so you subtract 5x
Y=-5x+17
This is in y=mx+b form
M=slope
B= y intercept
I hope this help :D
