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
Answer:
EBD is 135, ABE is 45
Step-by-step explanation:
Completing the square
alrighty
minus 31 both sides
x²+12x=-31
take 1/2 of the linear coefient and square it
12 is the linear coefient
12/2=6, (6)²=36
add that to both sides
x²+12x+36=36-31
factor perfect square trinomial
(x+6)²=5
square root both sides, remember to take positive and negative root
x+6=+/-√5
so what you want to write is
x+6=√5 and
x+6=-√5
the solutions
minus 6 both sides
x=-6+√5 and -6-√5
Answer: AB> AC> BC
Step-by-step explanation:
A+B= 134
A+C= 124
B+C= 102
Therefore, the sides from greatest to least are AB>AC>BC.
Answer: 40%
Step-by-step explanation:
Let the percent be x , then
x 110 = 44
110x = 4400
x = 4400/110
x = 40
Therefore : 44 is 40 percent of 110
