Answer:
The sample size for the data set = 56
Step-by-step explanation:
The sample size or number of individuals (n) is gotten from a histogram by summing up the total frequencies of occurrences.
In this example, the frequencies are: 2 4 6 8 10 12 14
Therefore, the sample size (n) is calculated as follows:
n = 2 + 4 + 6 + 8 + 10 + 12 + 14 = 56
Therefore the sample size for the data set = 56
Answer
The answer is x^2 + 5x - 6
Step by step explanation
You are given four trinomials, we have to find which trinomial is factorable.
x^2 + 3x - 6 cannot be factored.
x^2 + 5x -6 can be factored.
= (x + 6)(x -1)
The factors are (x-1) and (x - 6)
Other twos are cannot be factored.
The answer is x^2 + 5x - 6
Thank you.
Solving for part A

Domain of composition: x ≠ 0 i.e. Domain is the set of "Real numbers excluding number 0".
Solving for part B

Each tricycle has 3 wheels and one seat, so the ratio of seats to wheels is 1:3
Answer:
Slope=2
Step-by-step explanation:
Slope=rise/run
We can start at 2, 3 (you can start anywhere on the line)
Then go to 3, 5 (you can end anywhere on the line)
Rise=2
Run=1
2/1=2
Slope is 2. The uses up there were examples. It doesn't have to be the exact points.
