At a local veterinary office, 48% of dogs get their teeth cleaned, while 35% of cats get their teeth cleaned. Let po and be the sample proportions of dogs and cats at this veterinary office, respectively, who get their teeth
cleaned. Suppose 25 dogs and 32 cats from this veterinary office are selected at random to collect data on their
teeth-cleaning history
Which of the following is the correct calculation and interpretation of the standard deviation of the sampling
distribution of po-c?
O The difference (dogs - cats) in the sample proportions of those that get their teeth cleaned typically varies about
0.003 from the true difference in proportions
O The difference (dogs - cats) in the sample proportions of those that get their teeth cleaned typically varies about
0.017 from the true difference in proportions.
O The difference (dogs - cats) in the sample proportions of those that get their teeth cleaned typically varies about
0.054 from the true difference in proportions.
O The difference (dogs - cats) in the sample proportions of those that get their teeth cleaned typically varies about
0.131 from the true difference in proportions.

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
