Step-by-step explanation:
1. x^2 + 10x + 25
2. x^2 - 25
.........
The answer is D
(5-1)/(-2-3)=4/-5
Answer: B. Population X will require a larger sample size
Step-by-step explanation:
- If a random variable say p has skewed distribution (whether right or left ) in a population then a bigger sample size is needed to make sure that the sampling distribution follows normal distribution.
Given : Two population distributions labeled X and Y.
Distribution X → highly skewed
Distribution Y → slightly skewed.
Since Distribution X more skewed so , we will need a larger sample size of population X as compared to Y.
Hence, the correct answer is B. Population X will require a larger sample size
Answer: Depends on the orders pairs
Step-by-step explanation: You didn’t include the ordered pairs so I’ll just do an example.
(1,5). (2,11). And(6,13) Theese orders pairs represent a function because, there are no repeating X values.
(2,5) (2,10) and (5,45)
Theese ordered pairs do NOT represent a function because, the X values repeat.
A function can be linear and nonlinear, they can have repeating Y values but NO repeating X values.
A trick for this is to put a piece of paper and cover sections and see if your line “turns back”.
Hope I helped ^u^
Put the bottom middle of the protractor on pt Q
Then put the bottom of the protractor on QR
Then whatever degree is on QP is your answer to the first question.
The answer to the second question depends on what angle you got.
90> = Acute
90 = Right
90< = Obtuse
