Answer:
25 sheets of plywood will be needed
Step-by-step explanation:
Each sheet of plywood measures 
.
We have to cover the surface of the house, minus the surface of the hole of the stairs.
To know how many sheets will be needed, we divide the surface to be covered by the surface of each sheet
As we can't buy 0,75 of a sheet, we round it up, i.e. we will need 25 sheets of plywood for subflooring.
Answer:
f(4) = 9
Step-by-step explanation:
f left parenthesis x right parenthesis equals x squared minus 3 x plus 5
f(x) = x² - 3x + 5
f left parenthesis 4 right parenthesis equals
f(4) =
f(x) = x² - 3x + 5
When x = 4
f(4) = 4² - 3(4) + 5
= 16 - 12 + 5
= 9
f(4) = 9
To make a frequency table, you will need to find the lowest and highest average number of movies.
Numbers go from 0.5 to 4.5.
And example of frequencies you could use are:
0-0.9 (1)
1-1.9(5)
2-2.9(5)
3-3.9(2)
4-4.9(1)
The frequencies are in parentheses beside the intervals.
Answer:
x=8 & x=6
Step-by-step explanation:
compare the divisor x-3 with x-a which will give a=3 and then use remainder theorem.
