(15, 12, 15, 17, 11, 16, 19, 11, 3, 11, 13} Use the above data to calculate the mean, median, and mode ?

mean = sum of data / no of data

mean= 15+ 12+15+17+11+16+19+11+3+11+13/11

mean = 143/11

mean = 13

median = 13

because it is the one in the middle.

mode = 11

because it is the one appears many

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

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
