Answer:
-4-6x
Step-by-step explanation:
Distribute the -2
Answer:
y = 3x + 8
Step-by-step explanation:
to find slope intercept if we have 2 points use this formula:
find the slope first: m= (y2-y1)/ (x2-x1)
after get the slope, use this formula:
y-y1 = m(x-x1)
Answer:
m= (y2-y1)/ (x2-x1)
= (2-8)/ (-2-0)= -6/-2 = 3
y-y1 = m(x-x1)
y-8 = 3 (x-0)
y = 3x + 8

Answer:
0.081,0.2621,0.645,0.919
Step-by-step explanation:
Let X be the average speed of a car driving down freeway
Given that X is normal with mean as 70mph with a standard deviation of 5mph.
To convert to Z score we do

a) the probability that a randomly selected car is driving more than 77mph

b) probability that a randomly selected car is driving between 65 and 69 mph
= 
c) the probability that a randonly selected car is driving between 67 and 77mph
=
d) the probability that a randomly selected car is driving less than 77mph

Answer:
x=2/5
Step-by-step explanation:
Answer:
100 or 150 units of the product.
Step-by-step explanation:
R = x(1000-4x)
What is the value of x if R = 60,000?
x(1000-4x) = 60000
-4x^2 + 1000x = 60000
x^2 - 250x = -15000
x^2 - 250x + 15000 = 0
Factorize:
(x-100)(x-150) = 0
x-100 = 0 V x-150 = 0
x = 100 V x = 150
