The simplest fraction brake down is by 4 first so that gets you 4/10 then you go down by 2 and that gets you 2/5 when you put it in decimal you get .40 and if you put it in percentages you get 40%

Answer:

The probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216

Step-by-step explanation:

We are given that

The variance of the scores on a skill evaluation test=143,641

Mean=1517 points

n=343

We have to find the probability that the mean of the sample would differ from the population mean by less than 36 points.

Standard deviation, $\sigma=\sqrt{143641}$

$P(|x-\mu|$

$=P(|Z|$

$=0.9216$

Hence, the probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216

1 \ 3 ( 24p - 66) = 3p + 43

NeTakaya

1/3(24p-66) = 3p + 43= 1/3*24p-1/3*66=3p + 43= 8p-22=3p + 43=8p - 3p=43+22=5p=65=p=65/5=13 hope this helped!
