Answer:

f(- 7) = 147

Step-by-step explanation:

To evaluate f(- 7) substitute x = - 7 into f(x)

f(- 7) = 3(- 7)² = 3 × 49 = 147

Human blood may contain either or both of two antigens, A and B. Blood that contains only the A antigen is called type A, blood
Talja [164]

Answer:

A. 0.50

B. 0.85

C. 0.05

Step-by-step explanation:

A. Based on the initial statistics, 50% of the blood type is blood type O, hence the probability of choosing bold type O at random is 50/100, which is 0.50 to two decimal places.

B. The total number of donors that can donate to Blood type A is 85%, thus, the probability is 85/100, which is 0.85 to two decimal places.

C. The percentage of people that have the type AB blood is 5%, thus the probability of someone having the A antigen and blood type AB is 5/100, which is 0.05 to two decimal places.

Rohen decided to collect data to determine if the size of a student's home and the student's age are correlated. He determined t
Aliun [14]

To solve the problem we must know about the correlation coefficients.

<h3>What is the correlation coefficient?</h3>

The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.

  • 1 indicates a strong positive relationship.
  • -1 indicates a strong negative relationship.
  • A result of zero indicates no relationship at all, therefore, independent variable.

The correlation coefficient 0.2 denotes, "There is a weak positive relationship between the size of a student's home and the student's age".

Given to us

  • The correlation coefficient for the data is 0.2.

As we can see that the value of the correlation coefficient is 0.2, therefore, it is far from1 meaning the relationship is weak, while the '+' symbol denotes that the relationship is positive.

Hence, the correlation coefficient 0.2 denotes, "There is a weak positive relationship between the size of a student's home and the student's age".
