A purchaser of electric relays buys from two suppliers, A and B. Supplier A supplies two of every three relays used by the compa
Reptile [31]

Answer: Our required probability is 0.3162.

Step-by-step explanation:

Since we have given that

n = 60

Probability of success = \dfrac{2}{3}

Probability that at most 39 of these relays come from supplier A would be

P(X\leq 39)=binomcdf(60,\dfrac{2}{3},39)=0.3162

Hence, our required probability is 0.3162.

What is the mean ? i don’t need work but it could help

Answer:

The median is the middle number; found by ordering all data points and picking out the one in the middle.

You want to put the numbers in order:

47, 49, 49, 50, 52, 57, 57, 57, 61

Then you go one number at a time from both ends until you get into the middle:

47, 49, 49, 50, 52, 57, 57, 57, 61

47, 49, 49, 50, 52, 57, 57, 57, 61

47, 49, 49, 50, 52, 57, 57, 57, 61

47, 49, 49, 50, 52, 57, 57, 57, 61

47, 49, 49, 50, 52, 57, 57, 57, 61

So the answer is 52.

Tip: when you do this and you are left with two numbers that are in the middle, add them and divide them by 2.
