Here is a list or numbers. 6,7,2,4,6,6,9,5,3,3
Work out the medium
Work out the mean

Answers

Answer:

The medium - 6,6

The mean - 5.1 or 5

Step-by-step explanation:

The medium is the middle number(s)

The mean is when you average the numbers (adding them all up then dividing by how many numbers there are).

Answer: before u do all of this put the number in smallest to biggest the mean is u add all the number then when u get the answer u divide the number by how many numbers are there so 2 + 3+3+4+5+6+6+6+7+9= 51 now 15 divided by 10 =5.1 that is the mean

Now the medium is u put the number in smallest to biggest again 2334566679 now u have to find the numbers that are the same so u see how there is two 3's and three 6's in the numbers right so u have to look very carefully u could put 3 has the answer put that is not the answer because there is only two 3's and there is three 6's so which is bigger two 3's or three 6's three 6's is bigger so that is the answer.

A charity distributed 80 000 emergency packages during 2018. This number is
expected to increase by 15% each year.
Calculate how many emergency packages the charity expects to distribute in 2021.

Answers

Answer:

121670

Step-by-step explanation:

The number of packages can be defined with the function:

P(t) = P(t-1)*1.15 where t = the years and 1.15 represents the 15% increase.

Packages during 2018: P(2018) = 80000

Packages during 2019: P(2019) = P(2018)*1.15 = 92000

Packages during 2020: P(2020) = P(2019)*1.15 = 105800

Packages during 2021: P(2021) = P(2020)*1.15 = 121670

A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes. Each small box can hold 25 books and each large box can hold 50 books. There were 3 more large boxes sent than small boxes, which altogether can hold 450 books. Determine the number of small boxes sent and the number of large boxes sent.
There were ____ small boxes sent and ____ large boxes sent.

Answers

Answer:

there were 4 small boxes sent and 7 large boxes sent

Step-by-step explanation:

let s= number of small boxes

let y= number of small boxes

each small box can hold 25 books, so s small boxes can hold 25s books. Each large box can hold 50 books, so l large boxes can hold 50lbooks. Therefore, the total number of books 25s+50l equals 450.

Since there were 3 more large boxes sent than small boxes, if we add 3 to the number of small boxes, we will get the number of large boxes, meaning l equals s+3.

system of equations:

25s+50l=450

l=s+3

substitute values

7a - 4b

Step-by-step explanation:

Add the numbers ending with 'a' together, and then add the numbers ending with 'b' together.

First of all, I will put the letters beside each other.

2a + 5a = 7a

3b - 7b = - 4b

Therefore, the answer is 7a - 4b.
