A new night club opens. The first night 100 patrons attend. For each successive night for a month, 20 more attend. How many attend on the 7th night?

Arithmetic sequence formula finding the nth number:

an = a1 + (n – 1)d

A(7) = 100 + (7-1) 20

A(7) = 100 + (6)20

A(7) = 100 + 120

A(7) = 220

So, on the 7th night, there 220 patrons.

Suppose that past history shows that 60% of college students prefer brand c cola. a sample of 5 students is to be selected. base

creativ13 [48]

The probability is 0.337.

The probability that more than 3 prefer brand c is the same as finding the probability that 4 or 5 prefer brand c. Using a binomial distribution,

$_5C_4(0.6)^4(0.4)^{5-4}+_5C_5(0.6)^5(0.4)^{5-5}
\\
\\=\frac{5!}{4!1!}(0.6)^4(0.4)^1+\frac{5!}{5!0!}(0.6)^5(0.4)^0
\\
\\=5(0.6)^4(0.4)+1(0.6)^5(1)=0.33696\approx0.337$
