Given a mean of 7.6 and a standard deviation of 3.1, what is the z-score of the value 5 rounded to the nearest tenth?

kaheart [24]

Given mean μ = 7.6 and standard deviation σ =3.1

The z score value for x= 5 is given by

Z = $\frac{x - mean}{standard deviation}$

Z = $\frac{5 - 7.6}{3.1 }$

Z = -0.8387

The Z- score value rounded to nearest tenth is -0.8

The correct answer choice is A. -0.8

Answer:

96 yards

Step-by-step explanation:

This is basically just a huge addition problem that we can tackle (heh) in our heads.

If we gain yards, then we add.

If we lose yards, then we subtract.

If we started out at 50, the expression is

$50 + 7 + 2 - 1 + 4 - 5 + 27 + 4 + 5 + 0 + 3 - 2 - 1 + 1 + 2$ .

We can use the associative property of addition to simplify this. I'm just grouping together things that look easy to do in my head.

$50 + (7 + 2) - 1 + 4 - 5 + (27 + 4) + (5 + 0 + 3) (- 2 - 1) + (1 + 2)\\\\50 + 9 - 1 + 4 - 5 + (31 + 8) (-3 + 3)\\\\(50 + 9) - 1 + 4 - 5 + 39 \\\\59 - 1 + 4 - 5 + 39 \\\\58+4 + (-5+39)\\\\62+34\\\\96$

Hope this helped!
