Answer:
1. 50% or 0.5
2. 10/3
3. 1.12
4. 0.22
5. 2.49$
Answer:
0.619
Step-by-step explanation:
from the question we have the following data:
probability of motor 1 breaking = 65% = 0.65
probability of motor 2 breaking = 35% = 0.35
probability of motor 3 breaking = 5% = 0.05
since we have 3 motors the probability of any of them breaking down is = 
but what the question requires from us is the conditional probability of the first one being installed
we have to solve this questions using bayes theorem
such that:
= 
= 
= 0.618966
approximately 0.619
therefore the conditional probability ralph installed the first motor is 0.619
Answer:he would require 8.33 gallons of gas
Step-by-step explanation:
Mr Dow lives 16 miles from his workplace he drives to and from work five days a week. It means that the distance that he drives everyday to and from work would be
16 × 2 = 32 miles.
Then, the total distance that he drives in a week to and from work would be
32 × 5 = 160 miles
if his car gets 19.2 miles per gallon, it means that the amount of gas that he would use in one week, commuting to and from work would be
160/19.2 = 8.33 gallons
Answer:
-8b + 9 - 5k
Step-by-step explanation:
I am assuming the blue highlighted portion is your answer, and is not a part of the initial question
(-4b + 15 - 7k) - (6 + 4b - 2k)
Combine like terms
-4b - + 4b
Negative + Positive = Negative
-4b - 4b = -8b
15 - 6 = 9
-7k - - 2k
Negative + Negative = Positive
-7k + 2k = -5k
Put them all together:
0b + 9 - 5k
Simplify
-8b + 9 - 5k
I got the same answer as you (just in a different order)
Answer:
30) A) 0 / 15 = 0
31) A) 0/28 = 0
Step-by-step explanation:
30)
0 / 15 = 0
15/0 undefined
15 + 0 = 15
15 - 0 = 15
Answer:
0 / 15 = 0
31) Answer: A) 0/28 = 0
