Answer:
His time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.
Step-by-step explanation:
With an standard deviation of 3.2 minutes, it is clear that the maximum time taken by Roman to complete his run of 3 miles would be
Average time + standard deviation = 24.7 minutes + 3.2 minutes = 27.9 minutes
The minimum time taken by Roman to complete his run of 3 miles would be
Average time - standard deviation = 24.7 minutes - 3.2 minutes = 21.5 minutes
Hence, his time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.
Answer:
y = 0.5x +10
Step-by-step explanation:
If x represents the number of days since Rosie planted her tomato plant, then 0.5x is the number of centimeters it has grown. This growth is added to its initial height (10) to get the number of centimeters high the plant is after x days:
y = 0.5x +10
to get the equation of any straight line we simply need two points off of it, hmmm let's use the points in the picture below.
0.25% bc he is charged 5% per year so just multiple 5% times 5=0.25%
Answer:
B: 13.5 in^2
Step-by-step explanation:
The average length of this trapezoid is (4 in + 5 in)/2, or 4.5 in.
The height is 3 in.
Thus, the area is A = (average length)(height) = (4.5 in)(3 in) = 13.5 in^2
