Answer:
There are 252 possible outcomes.
Step-by-step explanation:
For each economic course, the student can select nine mathematic courses.
For each mathematic couse, the student can select four computer courses.
There are 7 economic courses.
So in all, there are 9*4*7 = 252 possible outcomes, that is, the number of different ways which the student can select his courses.
<u>Answer- </u>Wendy spent 3 hours on the train
<u>Solution-</u>
The distance between the cities= 500 mi.
She traveled part of the way by bus, and other part by train.
The bus averaged 40 mph, and the train averaged 120 mph.
The entire trip took 6.5 hours.
let d = distance traveled by train
the total distance was given as 500 mi ,
therefore, distance traveled by bus = (500-d) mi
time = distance/speed
⇒ train traveling time + bus traveling time = 6.5 hrs
⇒
⇒ d + 3(500-d) = 120(6.5)
⇒ d + 1500 - 3d = 780
⇒ 2d = 720
⇒ d = 360 mi
so d = 360 mi by train
⇒ 360/120 = 3 hrs on the train
Answer: 614
Step-by-step explanation:
Rounding to the nearest unit means to find the nearest integer to a given number.
Step 1: re write the number as
613 + 0.715 to see that 613. 715 is between
613 and 614, since 0.715 is more 613 but not up to 614. Also, the decimal 0.715 is greater than 0.5, therefore, we round up, please note that if decimal is less than 0.5, we round down.
Therefore, 613.715 rounded to the nearest unit is 614.
I hope this helps, mark as brainliest please
