Answer:
The mean is 24.205
Step-by-step explanation:
Firstly, we need to get the z-score
From the question, the probability we have is the probability that commuters take more than 22 minutes to commute one-way
So the probability we had was;
P( x > 22)
So we need the z-score corresponding to 63.70% or simply 0.637
We can use the standard normal distribution table to get this
Mathematically, from the standard normal distribution table this is -0.35
z-score = (x- mean)/SD
-0.35 = (22-mean)/6.3
22-mean = -2.205
mean = 22 + 2.205 = 24.205
Answer:
55 = 550
Step-by-step explanation:
Aftershocks occur after the most major part of an earth quake happens. Earthquakes occur at fault lines near the tectonic border. They occur because of the sudden movement for staying rigid while they were edging closer and closer. So the sudden movement releases a large amount of tension buried deep below the earth creating or resulting in an earthquake.
Answer:
Choice A: y = 3x + 2
Step-by-step explanation:
<u>Given</u>
y = -1/3x +4
<u>Reciprocate and switch sign</u>
-1/3
-3/1
3/1
<u>Simplify</u>
3/1 = 3
m = 3
<u>Answer</u>
The only answer choice with the slope of 3 is choice A, therefore that would be the answer.
