So. We are going to take the first example which is -2. The rule is what your going to "plug" or put -2 into. So your equation should look like -2^2-5 (^2 is that exponent) put that into your calculator and you should get -9. That -9 is your Y value. Your -2 is your X value . So your ordered pair is (-2,-9) just repeat steps for -1, 0, and 1. Hope this helps!
Number 9 is : it’s the constant of proportionality for this table because each time you arenumber 9 : because each time you are multiplying that number by 100
Answer:
-1 ≤ x ≤8 (don't care about the equal sign)
Step-by-step explanation:
-6+4≤2x≤12+4
=-2≤2x≤16
=-1≤x≤8
Answer: The explanation is correct.
Step-by-step explanation:
The interpretation of 95% confidence interval for population mean is that "A person can be 95% sure that the true population mean lies in it."
Given : The admissions director from Big City University found that (107.8, 116.2) is a 95% confidence interval for the mean IQ score of all freshmen.
Interpretation: The admissions director can be 95% sure that the true population mean IQ score of all freshmen lies in (107.8, 116.2).
i.e. There is a 95% probability (chance) that the interval from 107.8 to 116.2 contains μ.
Hence, the explanation is absolutely "correct" .
