The length of a rectangle is 5 more than twice the width. the perimeter is 130. what is the area?

vekshin1

L the length W the width

The length of a rectangle is 5 more than twice the width
L = 5+ 2W

the perimeter is equal the sum of sides =130

L+L+W+W =130

by subtitution we replace L by L = 5+ 2W

5+ 2W+5+ 2W +W+W = 130

6W= 120

w= 20 L = 5+ 2W= 5+ 40=45

A survey found that 35% of callers complain about the service they receive from a call center. Assume that the events of differe

sasho [114]

Answer:

0.336 or 33.6%

Step-by-step explanation:

It follows from the question that the probability of a complaint is 35% = 35/100 = 0.35. Let's call this probability, p.

The probability of no complaint is mutually exclusive of p since both are complements. Let's call this q. Then

q = 1 - p = 1 - 0.35 = 0.65

The distribution is a binomial distribution.

Events of each call are independent.

The probability of 2 calls with complaint out of 5 is

$\binom{5}{2}p^2 \timesq^3=10\times0.35^2\times0.65^3 = 0.336 = 33.6\%$
