Answer: 140cm 2
Step-by-step explanation: 8 x 5 = 40 x 4 = 115 + 25 = 140
Answer:
30.666 repeating
Step-by-step explanation:
Answer: 12
40% = 40/100 = 0.40
"of" means "multiply" in percent word problems like this. Multiply 0.40 with 30 to get 0.40*30 = 12
Optionally, you can solve the equation below for x
part/whole = percent/100
x/30 = 40/100
x/30 = 0.40
x = 0.40*30
x = 12
much of those steps follow a similar pattern to what was mentioned earlier.
2 1/3 = 7/3
Both numbers should be improper fractions.
11/3 + 7/3 = 18/3
Now the fractions must be simplified
18 ÷ 3 = 6
So 11/3 + 2 1/3 = 6
For this case we observe that we have a scatter diagram.
the values of "x" and the values of "y" are shown for the scatter diagram.
We observe that we have a trend line.
The trend line is a good approximation because it passes very close to all points of the scatter diagram.
Answer:
It can be a line of best fit because it is closest to most data points.
