Answer:D)78
Step-by-step explanation:70+71+75+75+88+89/6
Answer:
C=12
Step-by-step explanation:
2x12=24
3x12=36
5x12=60
There are 1760 yards in a mile
2 miles = 3520 yards
he runs 80 yards per practice (4×20)
3520÷80= 44
he needs to do the practice 44 times.
--------------
There are 128 oz in a gallon
he brought two gallons, meaning 256 oz
each cup holds 8 oz
256 ÷ 8 = 32
he can serve 32 cups.
Answer: Last Option

Step-by-step explanation:
In this case we have a uniform probability. In the graph the horizontal axis represents the possible values of the variable x and the vertical axis represents the probability P(x).
To calculate the probability that x is between 4.71 and 7.4 we calculate the area under the curve.
The horizontal length between 4.71 and 7.4 is:
.
Then notice that the vertical length in this interval is 0.125.
Then the area of a rectangle is:

Where l is the length and w is the width.
In this case we have to:


So
