Brianna received an overall IQ score of 117 on the Wechsler Scale. This means that Brianna has scored approximately____________

Tresset [83]

Using the normal distribution, it is found that the correct option is:

D. 1; 100

In a <em>normal distribution</em> with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

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

It measures how many standard deviations the measure is from the mean.

In this problem:

The mean on the Wechsler Scale is of 100, hence $\mu = 100$ .

The standard deviation is of 17, hence $\sigma = 17$ .

Brianna had an score of 117, hence $X = 117$

Then:

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

$Z = \frac{117 - 100}{17}$

$Z = 1$

Hence, the option d is correct.

PLEASE SEE ATTACHED IMAGE.

The length of an arc, by definition is given by:
s = R * theta
Where,
R: radio
theta: angle of the bow.
We then have to replace:
s = (6) * (135 * (pi / 180))
s = 14.1 in
Answer:
The length of the arc s is:
s = 14.1 in
