Which of the following has a slope of –2 and a y-intercept of 4?

1 answer:

6 0

The coefficient of x is the value for slope in y-intercept form, and the number that we add or subtract is our y-intercept. So in this case, we want to look for a "-2" in front of x and a +4 in the equation.
Answer choice A fulfills those conditions. (I am also assuming that answer choice A should have had an x in it, but you accidentally forgot to type it.)

Answer:

Step-by-step explanation:

Given that fish length X is having the normal distribution for which the mean is 9 inches and the standard deviation is 2 inches.

X : N(9,2)

A) $P(X$

B) Here sample size = 300

$P(X$

Out of 300 fish we can expect 300(0.3085) to be shorter

i.e. 92.55=93 fish

Find the measure of angle AOB

klasskru [66]

Answer:

101°

Step-by-step explanation:

20 + 25 = 45

3+2 = 5

5x + 45 = 180

Subtract 45 from 45 and 180 (both sides)

5x = 135

Divide 5x and 135 (both sides) by 5, to finally get..

x=27

3 x 27 + 20 = 101

2 x 27 + 25 = 79

Angle B.O.C = 79

Angle A.O.B = 101
