Step-by-step explanation:

Question 18

Diameter = Difference in y-coordinates
Diameter = 12 - 2 = 10
We know : Radius = Diameter/2
Radius = 10/2
Radius = 5 cm
(1) 5 cm

Question 19

3x² - 34x - 24 = 0
(3x + 2)(x - 12) = 0
Solution set = {-2/3, 12}
(3) {-2/3, 12}

Determine the SCALE FACTOR. Original image: 1.5 inches tall, 2 inches long. Scale Drawing: 3.75 inches tall, 5 inches long. (pic

Virty [35]

Answer:

scale factor is 2.5

Step-by-step explanation:

Notice that the original image is smaller than the scale drawing. Examine the ratios of the sizes:

Image/ Original :

height: 3.75 in / 1.5 in = 2.5

length: 5 in / 2 in = 2.5

The scale factor is clearly 2.5

Assume that adults have IQ scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equa

aleksley [76]

Answer: 0.5467

Step-by-step explanation:

We assume that the test scores for adults are normally distributed with

Mean : $\mu=100$

Standard deviation : $\sigma=20$

Sample size : = 50

Let x be the random variable that represents the IQ test scores for adults.

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

For x =85

$z=\dfrac{85-100}{20}\approx-0.75$

For x =115

$z=\dfrac{115-100}{20}\approx0.75$

By using standard normal distribution table , the probability the mean of the sample is between 95 and 105 :-

$P(85$

Hence, the probability that a randomly selected adult has an IQ between 85 and 115 =0.5467
