Which statement describes the mapping? Group of answer choices

A. The mapping does not represent y as a function of x, because two of the x-values corresponds to the same y-value.

B. The mapping represents y as a function of x, because each y-value corresponds to exactly one x-value.

C. The mapping does not represent y as a function of x, because there are more x-values than different corresponding y-values.

D. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.

What is the remainder when 3x^2-x-10 is divided by x-1 -6,-7,-8, or -9

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
