Answer: the probability that a truck drives between 166 and 177 miles in a day is 0.0187
Step-by-step explanation:
Since mileage of trucks per day is distributed normally, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = mileage of truck
µ = mean mileage
σ = standard deviation
From the information given,
µ = 100 miles per day
σ = 37 miles miles per day
The probability that a truck drives between 166 and 177 miles in a day is expressed as
P(166 ≤ x ≤ 177)
For x = 166
z = (166 - 100)/37 = 1.78
Looking at the normal distribution table, the probability corresponding to the z score is 0.9625
For x = 177
z = (177 - 100)/37 = 2.08
Looking at the normal distribution table, the probability corresponding to the z score is 0.9812
Therefore,
P(166 ≤ x ≤ 177) = 0.9812 - 0.9625 = 0.0187

Answer:
y = mx + b y = 1/4x + 1
m = 1/4
b = 1
Step-by-step explanation:
first you should distribute
y - 2 = 1/4(x - 4)
y - 2 = 1/4x - 1
and then isolate y by adding 2 to both sides of the equal sign to cancel out the negative 2 on the left
y - 2 = 1/4x - 1
+2 +2
y = 1/4x + 1
the slope (m) = 1/4
the y-intercept (b) = 1
