1 answer:

7 0

To solve the problem above, we will be using the equation in solving the surface area of a cylinder which goes. A = 2pi r^2 + 2pi r h, A is for the surface area, pi is 3.1416; h is the height and r is the radius. Basing on this formula the radius will be 0.3982 ft both top and bottom.

Answer:

A) 1/3200000

B) 19/20

Step-by-step explanation:

Percentage population of graduates = 5

Proportion of graduates from 100 random samples = percentage × number of samples

Proportion of graduates = 0.05 × 100 = 5

Probability of having 5 graduates among the 100 random samples:

P(1 graduate) = possible outcome / total required outcome

P(1 graduate) = (5 / 100) = 1/20

P(5 graduates) = (1/20)^5

P(5 graduates) = 1/3200000

Probability of never being a graduate = (1 - probability of being a graduate)

Probability of never being a graduate = ( 1 - (1/20)) = 19/20

Which equation can pair with x - y=-2 to create a consistent and dependent system?

kirill [66]

Answer: B; -3x+3y=6

Step-by-step explanation:

When you put -3x+3y=6 and x-y=-2 in slope intercept form, you get the same equation. Which is y=x+2. Therefore the equations are graphed on the same line and share infinitely many solutions and are consistent as well as independent.
