Determine the probability distribution's missing value. The probability that a tutor will see 0, 1, 2, 3, or 4 students x 0 1 2 3 4
p(x) 0 0 7/17 ? 5/17

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

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

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
