Toss five fair coins and let x equal the number of tails observed. a. identify the sample points associated with this experiment, and assign a value of x to each sample point. then list all the possible values of x. b. calculate p(x) for the values xequals2 and xequals4. c. construct a probability histogram for p(x). d. what is p(xequals1 or xequals5)?

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

pi x^2

step-by-step explanation:

pi times x squared

mariah is studying the life cycle of the monarch butterfly. she must choose one stage in the cycle to present in science class: egg, caterpillar, chrysalis, or adult. she plans to make her choice randomly using a custom spinner divided into four sections. first, however, she spins the spinner 50 times to see the frequencies it generates.

stage times landed on

egg 10

caterpillar 12

chrysalis 15

adult 13
