Answer:
a) y = n – 0.26n
Step-by-step explanation:
a) y = n – 0.26n
Answer:
2,2 is 4 minutes and 3,1 is 1/4 miles
(1.) 35-3m
m= 4
35-3m
= 35-3(4)
= 35-12 (do the multiple/division first before doing the addition/subtraction)
= 23
C. 23
(2.) 1 + x ÷ 5
x = 80
1 + x ÷ 5
= 1+80÷5
= 1+16
= 17
(3.) mx-y
m=5, x=3, and y=8
mx-y
= 5(3)-8
= 15-8
= 7
(4.) 3a+15+bc−6
a=7, b=3, and c=15
3a+15+bc-6
= 3(7)+15+3(15)-6
= 21+15+45-6
= 75

Step-by-step explanation:
Hi, you have not provided the distribution, I'll solve the problem for a particular distribution and you can apply the same method for yours.
Answer:
0.39
Step-by-step explanation:
X is the random event and P(X) is the probability of the event X, therefore, X is the number of televisions
Distribution:
X 0 1 2 3 4 5
P(X) 0.24 0.37 0.20 0.11 0.05 0.03
When they ask for the probability of at least Two televisions, they are asking for the probability that the householder has two or more television or P(X>2). To calculate the probability we need to add the probability of each event in the range:
P(X>2) = P(2) + P(3) + P(4) + P(5) = 0.20 + 0.11 + 0.05 + 0.03 = 0.39
