Answer:

NOT a function
domain: [-2, 2]
range: [-4, 4]

Step-by-step explanation:

A vertical line intersects the graph twice, so the relation is not a function. It is only allowed to intersect once if the relation is a function.

The domain is the horizontal extent, which is from -2 to +2.

The range is the vertical extent, which is -4 to +4.

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

A scale for a drawing is 5 centimeters= 1 meter. What is the scale in terms of centimeter to centimeters

umka2103 [35]

The scale in cm to cm is:

1 cm = 20 cm

Step-by-step explanation:

Scales are used to draw maps and blueprints of large objects on paper.

Given scale is:

5 centimeters = 1 meter

WE have to find the centimeter to centimeter scale. In order to do so, we have to convert the meters into centimeters

As there are 100 centimeters in a meter

So,

the scale will be:

5 cm = 100 cm

Simplifying:

The scale in cm to cm is:

1 cm = 20 cm
