Answer: 18.25
Step-by-step explanation:
5.5*4=22
401.5/22=18.25
The value of co-efficient of determination is 0.241.
<h3>What is the relationship between linear co-relation co-efficient and co-efficient of determination ?</h3>
The co-efficient of determination R² is similar to the linear correlation co-efficient.
We can think of co-relation of determination as a percentage. It gives us the data for how much percentage of data will fall within the linear co-relation.The higher the percentage the more data falls within.If the coefficient is 0.5 then 50% of data falls within the linear co-relation.
According to the given question
Linear correlation coefficient is -0.491
∴ Co-efficient of determination is (-.491)² which is equal to 0.241.

Step-by-step explanation:
3(3u-5)=39
9u - 15 = 39
9u = 15 + 39
9u = 54
divide both by 9
u = 54/9
u = 6
Answer:
240 cubic units
Step-by-step explanation:
5*6=30 (the base they show)
30*8=240
Well we know that the ratio is 2 boys : 4 girls, 2*2=4, if there are 12 boys the ratio would be 12 boys : 24 girls because 12*2=24. Thus, the new ratio is 12 boys : 24 GIRLS
