Answer: The answer is 6.
The number sentence is
3-3=0
10-4=6
So, 13-7=6
Step-by-step explanation:
To solve
, by making ten
First break 13 and write 
Then break 7 as 
Now to subtract 7 from 13,
Step 1. Subtract 3 (a part of 7), from 3(a part of 13) or cross 3 circles, then we have left 10-4

Step 2. Subtract 4 from 10 or cross 4 circles out of 10, we get 6.
The answer is 6.
The correct answer is …..3, 2 1/4, 2 1/2
Answer:
Standard score z=0.07
Step-by-step explanation:
The z-score, or standard score, represents an equivalent value for X but in the standard normal distribution, where μ=0 and σ=1.
For X=28.3 in a normal distribution with μ=26.3 and σ=28.1, the standard score can be calculated as:

This value is 0.07 standard deviations right to the mean.
In the picture attached, we have located the z-score.
Answer:
b is 10 times greater
Step-by-step explanation:
If we multiply the first ratio by 2/2, we get 2/10. Since b=10 and c=1, b is 10 times greater.
