. Seven balls are randomly withdrawn from an urn that contains red, 16 blue, and 18 green balls. Find the probability that

a. red, blue, and green balls are withdrawn;

b. at least red balls are withdrawn;

c. all withdrawn balls are the same color;

d. either exactly red balls or exactly 3

answer: i'm not sure

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.

pls mark as brainliest

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
