Answer:
Step-by-step explanation:
The z-score tells us how many standard deviations a value is away from the mean.
The formula is:
where x is the value, is the mean, and s is the standard deviation.
We want to find the z-score for the score of an 83, the mean is 72, and the standard deviation is 5.
Substitute the values into the formula.
Solve the numerator.
Divide.
The z-score is 2.2, which means the score of 83 is 2.2 standard deviations above the mean.
Hello russell6333!
Solve for x.
- 144 = 12x
- 45 = 4x - 27
- 2x - 2 = 14
- 12x = 44 - 10x

<h3><u>NOTE </u><u>:</u><u>-</u></h3>- To solve questions of these sorts, bring all the terms to one side & simplify it leaving x alone in the other side of the equation (other side of the equal to sign). After simplification you'll get the value of x.
- Remember that the signs & operations will change when you bring a term to the other side of the equation.
- So, addition will become subtraction, subtraction will become addition, multiplication will become division & division will become multiplication.
