Answer:

(a) z(105)= (105-95)/10

= 1

z(85)= (85-95)/10

= -1

P(85< x < 105) = P(-1< z < 1) = 0.6825

Quantity of people of 1600 that have IQ between 85 and 115 = 0.6825*1600= 1092

(b) z(105) = (115-95)/10 = 2

z(85) = (75-95)/10 = -2

P(-2< z < 2) = 0.6827

quantity of people of 1600 that have IQ between 75 and 115 = 0.6825x1600=1092

(c) Z(>125)=( 125-100)/10=3

What is the slope of the line that passes through the points ( 5 , − 10 ) (5,−10) and ( 11 , − 12 ) ? (11,−12)? Write your answe

yan [13]

The slope of the line that passes through (5,−10) and ( 11 , − 12 ), in simplest form is: -1/3

Recall:

The slope of a line passing across through two points can be calculated using: $m = \frac{y_2 - y_1}{x_2 - x_1}$

Given two points:

(5,−10) and ( 11 , − 12 )

Let,

$(5,-10) = (x_1, y_1)\\\\( 11 , - 12) = (x_2, y_2)$

Substitute

$m = \frac{-12 - (-10)}{11 - 5}$

Slope (m) = -2/6

Slope (m) = -1/3

Therefore the slope of the line that passes through (5,−10) and ( 11 , − 12 ), in simplest form is: -1/3
