Answer: c) About 16% of the variation in value of the car is explained by a linear relationship with the age of the car.
e) The correlation coefficient, r, is 0.397.
Step-by-step explanation:
Given that:
Coefficient of determination (r²) between two variables, age of car (x) and value of car (y) = 0.158
Correlation of determination (r²) of 0.158 = (0.158 × 100% = 15.8% of the variation between the two variables can be explained by the regression line). Hence, about 16% of the variation between age and value of car can be explained by the linear relationship.
Coefficient of correlation (r) = sqrt(r²) = sqrt(0.158) = 0.397
Answer:
5.6 x 5.6 x 6.16 x 6.16=1190
Step-by-step explanation:
5.6 x 5.6 x 6.16 x 6.16=1189.974016
Rounded up will be 1190.
Answer:
1 r= 68/55
2 no solution
Step-by-step explanation:
Since we need to determine how long it takes for the watt hours to consume 4320 watt hours, we would need to divide.
We would simply divide.
4320/950= 4.5
The 4.5 represents how long it would take for the light bulb to consume 4320 watt hours.
Therefore, the answer would be 4.5 days.
<u>Answer</u>
4.5 days
<u>Recap</u>
1. We read the problem and determined that in order to solve the problem we would need to divide.
2. We then divided 4320/960= 4.5
3. We came to the conclusion that 4.5 days would be the answer.
