Answer:

A. -0.87

Step-by-step explanation:

The correlation coefficient is a measure of the strength and nature of the linear relationship between two variables, one dependent and one independent. This coefficient takes values between -1 and 1, indicating with its sign whether the relationship is direct or inverse between the variables involved and with its absolute value indicates the strength of the linear relationship between them. A coefficient with absolute value close to 1 indicates great strength and better fit.

Conclusion: The best coefficient, of the propuetso in the problem, is that of -0.87, which indicates a strong relationship between the variables, a good fit and an inverse relationship between them.

A random sample of 12 students used Method A, and their increase in points averaged 46.31, with a sample standard deviation of 6
Kitty [74]

Answer:

The null hypothesis is   H_o  :  \mu_A  - \mu_B  =  0

The alternative hypothesis is  H_a :  \mu_A - \mu_B > 3  

Step-by-step explanation:

From the question we are told that

  The mean of method A is \mu_A =  46.31

  The standard deviation of method A is  \sigma  = 6.44

   The  mean of method B is  \mu_B   =  42.79

   The standard deviation of  method B  is  \sigma_B  =  7.52

An appropriate set of null and alternative hypothesis to determine whether Method A increases students points by more than 3 points is

The null hypothesis is   H_o  :  \mu_A  - \mu_B  =  0

The alternative hypothesis is  H_a :  \mu_A - \mu_B > 3

The measures of two angles of a triangle are 36° and 28°. What is the measure of the third angle?
galina1969 [7]

Answer: 116 degrees.

Step-by-step explanation:

Interior angles of a triangle add to 180.

Knowing the first two angles are 36 and 28, you can subtract them from 180 to find the answer:

180 - 36 - 28 = 116

Alex17521 [72]

Answer:

W is 6

L is 19

Step-by-step explanation:

L= 4W - 5

P= 2L + 2W

P= 2(4W-5) +2W

50=8W -10 +2W

60 = 10W

W= 6

L= 19
