Respuesta :

1) fill the numbers into your equation
2) 130-135=-5
3) now you should have -5 divided by 5, divided by the square root of 28
4) simplify the equation to -1 divided by the square root of 28
5) you now need to multiply both the numerator and the denominator by the square root of 28 divided by the square root of 28
6) you have now got the square root of 784 and you can now simplify the denominator to 28
7) your equation should be Z= -1 multiplied by the square root of 28 over 28
8) depending on how your teacher wants you to simplify your answer can stop there or go even farther to -5.29/28

The value of z using the information and the formula provided in the question is -5.292.

What is the value of z?

Subsituting for the missing values in the formula, the formula becomes: [tex]\frac{130 - 135}{\frac{5}{\sqrt{28} } }[/tex]

Solving for the numerator, the number becomes -5. Solving for the denominator, the number becomes 0.94491

z = -5/0.94491

z = -5.292
