Z score=(data value-mean)/standard deviation
z=(90-100)/15=-0.6666666667
To find this I would use the pythagorean theorem which is:
a^2 + b^2 = c^2
Since we already know c = hypotenuse, and a side of the shorter sides we can plug them it like this:
11^2 + b^2 = 12^2
121 + b^2 = 144
b^2 = 23
√23 = 4.79
Round:
B. 4.8 would be your answer!
The answer is D
Because there are two x’s
And 5 number 1’s
So 2x=5
