To find the mean, add all the numbers, then divide by the amount of numbers there are. I'll do the first one as example.
6+5+6+9+9+11=46.
46 divided by 6 = 7.66
To find the median, put all the numbers in order from biggest to smallest.
5, 6, 6, 9, 9, 11.
Since there is an even amount of numbers, you have to add the two middle numbers (6,9) and divide by two.
6+9= 15
15 divided by 2 = 7.5
To find the mode, you just have to find the most common number. In this case, there are two most common numbers (6,9) so the answer would be both.
5,6,6,9,9,11
Answer:
Mean: 7.66
Median: 7.5
Mode: 6,9

A rectangular metal plate is measured to be 7.6cm long and 3.1cm wide, both correct to one decimal place.

ElenaW [278]

Answer:

We know that the rectangular plate has measures of:

length = 7.6 ± 0.05 cm

width = 3.1 ± 0.05 cm

(the error is 0.05cm because we know that both measures are correct to one decimal place)

First, the upper bound of the length is equal to the measure of the length plus the error, this is:

L = 7.6 cm + 0.05 cm = 7.65 cm

The upper bound of the area is the area calculated when we use the upper bound of the length and the upper bound of the widht.

Remember that the area for a rectangle of length L and width W, is:

A = W*L

Then the upper bound of the area is:

A = (7.6cm + 0.05cm)*(3.1cm + 0.05cm) = 10.8 cm^2

PLEASE HELP!!!!! 3, 8, 13, 18, 23, .... The recursive formula for this sequence is:

rodikova [14]

Answer:

a₈ = 37

Step-by-step explanation:

The given arithmetic sequence is: 3, 8, 13, 18, 23, . . .

The recursive formula for the sequence is: $a_n = a_{n - 1} + 5$

Here, $a_n$ represents the $n^{th}$ of the sequence.

And, $a_{n - 1}$ represents the $(n - 1)^{th}$ of the sequence.

'+5' denotes that '5' is added to the $(n - 1)^{th}$ term to get the $n^{th}$ term. In other words, the difference between two consecutive numbers in the sequence is 5.
