On a survey, 8 students reported how many minutes it takes them to travel to school. Here are their responses. 4, 16, 4, 13, 4, 7, 4, 15
Find the mean travel time for these students.
If necessary, round your answer to the nearest tenth.

9.6

Step-by-step explanation:

When it says find the mean, it basically means find the average. So we'll add the numbers and divide by the amount of numbers there are (7).

(4+16+4+13+4+7+4+15)/7 = 9.571

Round to the nearest tenth, 9.6.

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
