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:
17
Step-by-step explanation:
Second square number is 9; 3×3
second cube number is 8; 2×2×2
9+8=17.
188.8 meters because you have to add 103.2+85.6 = 188.8 meters
Answer:
<h3>Y=1/3x+3</h3>
Step-by-step explanation:
To solve this problem, first, you have to use the slope formula of y₂-y₁/x₂-x₁=rise/run. Remember to solve this problem, use slope-intercept form of y=mx+b.
m represents the slope.
b represents the y-intercept.
Y₂=4
Y₁=1
X₂=3
X₁=(-6)
Solve & simplify.
The slope is 1/3.
Y-intercept is 3.
y=1/3x+3
In conclusion, the correct answer is y=1/3x+3.
