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.

a ski shop has a markup rate of 50% find the selling price of skis that cost the store owner $300. tell me how you got the answe

rusak2 [61]

If nthe shop has a mark up rate of 50% and they cost 300 to buy you multiply 300 by 50% convert 50% to decimal
so you do .5*300=150
then you add 150 to 300 which means that the shop sells the skis for 450 dollars.
