Answer: 0.1824
Step-by-step explanation:
Given : The mileage per day is distributed normally with
Mean : 
Standard deviation : 
Let X be the random variable that represents the distance traveled by truck in one day .
Now, calculate the z-score :-
For x= 132 miles per day.
For x= 159 miles per day.
Now by using standard normal distribution table, the probability that a truck drives between 132 and 159 miles in a day will be :-
Hence, the probability that a truck drives between 132 and 159 miles in a day =0.1824
You would take the CUBED ROOT of 125 instead of the square root, this will help find your answer..
It’s 5, because 5^3 is 125
y=3 when x=15
this is because we can set up a ratio of when x/15 and set it equal to 6/30 and divide them, solve for x.
<span>The correct answer is: 21
Explanation:
Let's first assume few variables!
x = Ishann's age (in years)
y = Christopher's age (in years)
1. Ishann is 3 times as old as Christopher can be represented mathematically as:
x = 3y ---- (1)
2. Ishann is 14 years older than Christopher can be represented mathematically as:
x = y + 14 ---- (2)
Get the value of y from Equation (1) and plug it in Equation (2):
(2) => x = (x/3) + 14
3x = x + 42
2x = 42
x = 21
Hence Ishann is 21 years old!</span>
Answer:
V = 270 cm³
Step-by-step explanation:
Remember your volume formula: V=<em>lwh</em>
So, plug in all your variables and multiply:
(6)(5)(9) = 270
And we have our final answer!
