A. Median number is the middle number. We can cross one off from left to right to get 4.
B. Interquartile range is Q3-Q1. Q1 is 2 and Q3 is 5, so the interquartile range is 3.
C. I don't know the original set, but an outlier can affect the mean.

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.

Coach velez took the basketball team out for ice cream sundaes.He bought 8 sundaes at $5.35 each.He left a 15% tip.How much did

joja [24]

To find the value of Coach Velez's total bill, first we must figure out how much the total of all of the ice cream sundaes were.

To do this, we must multiply the number of sundaes (8) by the cost of each sundae ($5.35).

8 * 5.35 = $42.80

However, Coach Velez also left a tip of 15%. To find out how much Coach Velez tipped, we have to multiply his regular bill ($42.80) times the amount he is tipping (15% or 0.15)

$42.80 * 0.15 = $6.42

Finally, we just have to add the bill ($42.80) and the tip ($6.42) together to find Coach Velez's total amount.

$42.80 + $6.42 = $49.22

Coach Velez spent $49.22 in all.

In a genetics experiment on peas, one sample of offspring contained 376 green peas and 117 yellow peas. Based on those results

scZoUnD [109]

Answer:

Step-by-step explanation:

Given that in a genetics experiment on peas, one sample of offspring contained 376 green peas and 117 yellow peas.

Total no of peas = 376+117=493

No of green peas = 376

Probability of selecting a green pea = $\frac{376}{493} =0.7627$

Yes it is reasonably close to 3/4 = 0.75 since difference is only 0.0127 negligible.
