A major car dealership has several stores in a big city. The owner wants to determine if there is a difference in the proportion of SUVs that are sold at stores A and B. The owner gathers the sales records for each store from the
past year. A random sample of 55 receipts from store A shows that 30 of the sales were for SUVs. Another random
sample of 60 receipts from store B shows that 42 of the sales were for SUVs. Assuming conditions for inference
are met, what is the 99% confidence interval for the difference in proportions of sales that are SUVs?

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
