For each of the examples below, decide if X is a binomial random variable. If so, specify n and p. If not, explain why not. a. X 5 number of heads from flipping the same coin ten times, where the probability of a head 5 1/2. b. X 5 number of heads from flipping two coins five times each, where the probability of a head for one coin 5 1/2 and the probability of a head for the other coin 5 1/4. c. X 5 number of cities in which it will rain tomorrow among five neighboring cities located within 10 miles of each other. d.

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
