Answer:

26

Step-by-step explanation:

Data provided in the question:

set {1, 2, 3, 5, 11}

Now,

Total number of different choices of a number available = 5

Therefore,

Number of ways to choose 2 distinct numbers=  ⁵C₂

Number of ways to choose 3 distinct numbers=  ⁵C₃

Number of ways to choose 4 distinct numbers=  ⁵C₄

Number of ways to choose 5 distinct numbers=  ⁵C₅

therefore,

Total number we can get

= ⁵C₂ + ⁵C₃ + ⁵C₄ + ⁵C₅

= \frac{5!}{2!(5-2)!}+\frac{5!}{3!(5-3)!}+\frac{5!}{4!(5-4)!}+\frac{5!}{5!(5-5)!}

=  \frac{5\times4\times3!}{2!3!}+\frac{5\times4\times3!}{3!\times2!}+\frac{5\times4!}{4!\times1!}+\frac{5!}{5!\times0!}

= 10 + 10 + 5 + 1

= 26

The line plot shows the weight of the bags of beans.what is the average weight of the bags.
Setler79 [48]

Answer:

1/2

Step-by-step explanation:

So you have 12 bags total.

2 are 1/6 so their total weight is 1/3

2 are 1/3 so their total weight is 2/3

3 are 1/2 so their total weight is 3/2

4 are 2/3 so their total weight is 8/3

1 is 5/6 so their total weight is 5/6

Now add all of these up:

1/3 + 2/3 + 3/2 + 8/3 + 5/6 = 36/6 = 6

Then divide by the number of bags to get the average weight: 6/12 = 1/2
