Answer:
7 is the mean
Step-by-step explanation:
because you add 5 in Jan 8 in Feb 6 in Mar 9 in April and then divide by 4 because that how many numbers there are in total
5+8+6+9=28
28/4=7
divide 28 and 4
It’s better to have a low score and for the second one thumber I think....
Answer:
There are 8 cans on each of the equal shelves
Step-by-step explanation:
Total number of cans put in display = 35
Shelves with equal no of cans = 4 Shelves
And one shelf displays only 3 cans
Therefore, 4 shelves with equal no of cans + 1 shelf with 3 cans = 35 cans
Let us assume equal no. of cans be x
We get, 4x + 3 = 35
4x = 35 - 3
4x = 32
x = 32 ÷ 4
x = 8
<u><em>Thus, 4 shelves with equal no of cans contains 8 cans each.</em></u>
The formula for this type of question is z=x-u/y
z=-2 (z-value)
u = 27 (mean)
y = 4 (standard deviation)
Therefore -2=x-27/4
You now figure this out like a normal equation
4x-2=4 X x-27/4
-8+27= x-27+27
19=x
Therefore the data value of x is 19
