On a recent quiz, the class mean was 72 with a standard deviation of 4.2. Calculate the z-score (to 2 decimal places) for a pers

barxatty [35]

Answer:

The Z score of the person is -3.09.

Step-by-step explanation:

The standard normal deviate (Z) for a normal distribution is given by

$Z=\frac{X-\bar{X}}{\sigma }$

where,

X = the value of observation

$\bar{X}$ is mean of the observations and

σ = standard deviation of the score

Applying values we get

$Z=\frac{59-72}{4.2}=-3.09$

one x-intercept for a parabola is at the point (-6,0) find the other x-intercept for the parabola defined by this equation y=x^2

Tanya [424]

Hello.

First off, you can factor this equation to find the missing x-intercept.

y = x² + 8x + 12
y = (x + 6)(x + 2)

Then, you can use the zero product property to find the x values.

x + 6 = 0 x + 2 = 0
- 6 - 6 - 2 - 2
x = -6 x = -2

As an ordered pair: (-6, 0) and (-2, 0)

Thus, your answer is x = -6, -2.
