ANSWER:
The definition is in the step by step
STEP-BY-STEP EXPLANATION:
The opposite of a number is the number that, when added to it, results in the number 0.
Every integer number has its opposite.
The opposite of a number has the same absolute value, but the opposite sign.
Which means that a pair of opposite integers are the negative and positive versions of a number together, for example, 3 and -3 are a pair of opposite integers.
Answer 1 3/5 × 40=64
Step-by-step explanation:
4×2/5=1 3/5 4×10=40
Using a calculator for the chi-square distribution, the critical value is given by:
A) 20.090
<h3>How to find the critical value of the chi-square distribution?</h3>
For a chi-square critical value, three parameters are needed:
- The number of degrees of freedom, which is one less than the sample size.
In this problem, we have a one-tailed test(as we are testing if the mean is greater than a value), with a significance level of 0.01 and 8 df, hence, using a calculator, the critical value is of 20.09, hence option A is correct.
