Correlation coefficient of the data is 0.9.
Answer: Option C.
<u>Explanation:</u>
Correlation is the relation of one variable with the other variable. It shows the effect on one variable because of the other variable. The coefficient of the correlation varies from 1 to -1.
The correlation coefficient of this scatterplot is 0.9 because the data points are not scattered in this scatterplot and are rather clustered. Moreover the slope is from left to right which is in the upward direction. So the coefficient is positive.
Answer: $45
Step-by-step explanation:
Simple interest is calculated as Principal x Rate x Time/100
From the information given,
Principal = $250
Rate = 12% = 12/100 = 0.12
Time = 18 months; because time is given in months, we divide by 12; time is therefore stated as 18/12.
Step 2: Plug the values into the formula:
Simple interest = 250 x 0.12 x 18/12
= $45
14/12=1 and 2/12= 1 and 1/6
31/10= 3 and 1/10
