A survey was conducted to determine how many movies were seen in one month among the 26 students in Mrs. Hampton's sixth-grade class. The results are shown in the dot plot below. Mrs. Hampton's Sixth-Grade Class Х х X X Х Х Х Х Х X Х Х X X X Х x Х Х X Х Х Х X 0 1 1 2 3 5 6 7 8 9 10 a) Calculate the measures of center for the data in the dot plot, rounding your answers to the nearest tenths place.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
