Answer:
Step-by-step explanation:
The length and the width are based on the height.
height: h
length: 5h + 2
width: 3h - 2
If the sum of those is 126, then:
h + 5h + 2 + 3h - 2 = 126 and
9h = 126 so
h = 14
length is 5(14) + 2 which is 72
width is 3(14) - 2 which is 40
The volume is found by multiplying the length times the width times the height:
14 * 72 * 40 = 40,320 inches cubed
1.x2x
+x.4x7
5.036 (sorry the underline function is no longer available)
In the thousandth column we have x +7 and we wind up with a 6 in that column.
Since 7 is already more than 6 that means the only number that will work is 9 and there will be a carry of one into the hundredths place.
1.x29
+x.4x7
5.036
Now let's look at the tenths column. 2 becomes 3 in the answer and there was a carry of 1 from the thousandths so the other number must be a zero
1.x29
+ x.407
5.036 Now I need a number that goes with 4 and puts a zero in the answer.
That number has to be 6 and does cause a carry of one into the ones
place
1.629
+x.407
5.036
Finally (remembering there is a carry of one in the ones place) I have two (1 + 1 carried) toward my five in the answer. I need three more.
Here is the final example:
1.629
+3.407
5.036

Step-by-step explanation:
Answer:
75% of college students exceed 6.63 minutes when trying to find a parking spot.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 10 minutes
Standard Deviation, σ = 5 minutes
We are given that the distribution of time for parking is a bell shaped distribution that is a normal distribution.
Formula:
P(X < x) = 0.25
We have to find the value of x such that the probability is 0.25.
P(X < x)
Calculation the value from standard normal z table, we have,
Hence, 75% of college students exceed 6.63 minutes when trying to find a parking spot.
