Answer:
The greatest number of groups he could have made is 4 groups
Each of the four groups will have:
4 Squares each
7 circles each
Step-by-step explanation:
16 squares
28 circles
Find the highest common factor of 16 and 28
16: 1, 2, 4, 8, 16
28: 1, 2, 3, 4, 7, 14, 28
The highest common factor of 16 and 28 is 4
This means the greatest number of groups he could have made is 4 groups
Each of the four groups will have:
16 squares = 16 / 4
= 4 Squares each
28 circles = 28 / 4
= 7 circles each
Each of the four groups will have:
4 Squares each
7 circles each
Answer:
79.1
Step-by-step explanation:
Given that :
Mean, μ = 62
Standard deviation, σ = 5.7
The value, x that is +3 standard deviations from the mean :
x = μ + 3(σ)
x = 62 + 3(5.7)
x = 62 + 17.1
x = 79.1
It could be 2+1 beacuse it says there are twice as many
To calculate for the percent of decrease:
First: work out the difference between the two numbers that you are given with.
Decrease = Original Number - New Number
Second: divide the decrease by the original number and multiply the answer by 100.
In formula terms it would look like this percent of decrease = Decrease ÷ Original
Number × 100
= (87-75) / 87 x 100
= 12/87 x 100
= 0.137931034 x 100
=13.79%
