<span>Assuming that 2 people who will repair a refrigerator equally fast will do it twice as fast when working together:
Jannete repairs 1/60 refrigerator per minute.
Lisa repairs 1/40 refrigerator per minute.
Togheter they repair 1/60+1/40= 1/60 + 1,5/60 = 2,5/60=5/120=1/24 refrigerator per minute
thus it will take them 24 minutes</span>
Answer:
b
Step-by-step explanation:
24*pi=75.4
circumference is found when diameter is multiplied by pi
For a probability distribution to be represented, it is needed that P(X = 0) + P(X = 1) = 0.44. Hence one possible example is:
<h3>What is needed for a discrete random variable to represent a probability distribution?</h3>
The sum of all the probabilities must be of 1, hence:
P(X = 0) + P(X = 1) + P(X = 3) + P(X = 4) + P(X = 5) = 1.
Then, considering the table:
P(X = 0) + P(X = 1) + 0.15 + 0.17 + 0.24 = 1
P(X = 0) + P(X = 1) + 0.56 = 1
P(X = 0) + P(X = 1) = 0.44.
Hence one possible example is:

Put 8 into fraction form: 8/1
Put 1 2/5 into a mixed number: 1*5+2 as numerator and 5 as denominator (7/5)
Now multiply 8/1 by the reciprocal of 7/5, which is basically just the numerator and denominator flipped, so 5/7. This is like dividing.
8/1*5/7= 40/7
40/7= about 5.7.
So, your answer would be 5.7 batches, or 5 complete batches would be a better answer.
That no matter what if you feel good about yourself you do better at what your doing. Hope I helped!
