Hope this helps I'm 80% sure this right.
Step-by-step explanation:
there should be at least
1) <span>30x4 − 20x3 + 15x2
This is the answer to 1. Don't forget to rearrange the terms in ascending order. That can trip people up.
2) </span><span>x3 + 8x2 + 13
Don't forget to check the terms sign. The subtraction symbol switches them all. </span>
Answer:
B. the lower the father's blood sugar level the lower the son's blood sugar level
Step-by-step explanation:
Correlation coefficient is the measure of relationship or association between two variables. It ranges between -1.0 and 1.0, negative correlation coefficient(-1.0 to 0) means there is negative relationship between the two variables, an increase in one variable leads to a decrease in the other. Positive correlation coefficient (0 to 1.0) means that there is a positive relationship between the two variables, an increase in one variable leads to an increase in the other variable. And correlation coefficient of 0.0 shows that there is no relationship between the two variables. For the case above, the correlation coefficient of 0.84 shows that there is a strong positive correlation coefficient between father's blood sugar levels and son's blood sugar levels, so the lower the father's blood sugar level the lower the son's blood sugar level
