It is a timed quiz. 50 points. 6th-grade math. Answer the question in the picture!

its 3 hours.

Step-by-step explanation:

a. 3 hours

Step-by-step explanation:

So to calculate the mean, you have to add all the terms together, then divide by the number of terms, so:

1 + 1 + 2 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 3 + 4 + 4 + 4 + 4 + 5 + 5 + 5 + 6 + 6 = 68

68 ÷ 20 = 3.4

and since we don't have a 3.4 a an option, we're going to round it to 3

So the mean score of the hours spent on homework for the 8th grade math students is 3 hours

if this is wrong let me know

for the points

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
