Answer:

\frac{2}{3} (x+6)

Step-by-step explanation:

\frac{2}{3} x+4= \frac{2}{3} (x+4÷\frac{2}{3})

\frac{2}{3}x+4 = \frac{2}{3} (x+4×\frac{3}{2})

\frac{2}{3}x+4 = \frac{2}{3} (x+\frac{12}{2})

\frac{2}{3}x+4 = \frac{2}{3} (x+6)

Assume that adults have IQ scores that are normally distributed with a mean of mu equals 105 and a standard deviation sigma equa
kondor19780726 [428]

Answer:   0.6827

Step-by-step explanation:

Given : Mean IQ score : \mu=105

Standard deviation : \sigma=15

We assume that adults have IQ scores that are normally distributed .

Let x be the random variable that represents the IQ score of adults .

z-score : z=\dfrac{x-\mu}{\sigma}

For x= 90

z=\dfrac{90-105}{15}\approx-1

For x= 120

z=\dfrac{120-105}{15}\approx1

By using the standard normal distribution table , we have

The p-value : P(90

P(z

Hence,  the probability that a randomly selected adult has an IQ between 90 and 120 =0.6827

Statisticians use ______ scores to divide the ______ under a curve the way people use a knife to cut pizza. Just as the pizza is
solong [7]

Answer:

Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.

Step-by-step explanation:

Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.

z-score:

  • A z-score is a numerical measurement which is measured in terms of standard deviations from the mean.
  • Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

  • If a z-score is 0, it tells that the data point is same as the mean.
  • Area under the normal curve is 1.
