Answer:

Step-by-step explanation:
Given
A roll of a pair of dice
Required
The probability of getting different numbers
First, list out the sample space;
We have:


The total is:

The outcomes of the different numbers are:



The total is:

So, the probability of having a different outcome is:



A z-score<span> is the number of standard deviations from the mean a data point is.
</span>
Standard deviation explains by how much the members of a group differ from the mean value for the group.
Using the z-score formula:
z = ( x - μ ) ÷ σ
Where;
x = score
μ = Mean
σ = Standard deviation
Z- Score (Tara) = ( 52 - 64 ) ÷ 8
= - 12 ÷ 8
= - 1.5
Z- Score (Jamal) = ( 82 - 64 ) ÷ 8
= 18 ÷ 8
= 2.25
Z- Score (Samuel) = ( 66 - 64 ) ÷ 8
= 2 ÷ 8
= 0.25
Answer:
x=1
Step-by-step explanation:
4x+3=7
7-3 = 4
4x=4
4/4 = 1
