Answer:
D. 5.6 ft
Step-by-step explanation:
- 40 ft - 12 ft = 28 ft (You subtract the leftover wire(12 ft) from the total amount(40 ft) so you can see how much wire was used to make the 5 cables. There was 28 ft of wire in total used to create the 5 cables.)
- 28 ÷ 5 = 5.6 ft (You divide 28 by 5 so that you can see how much wire was used for each cable.)
- <u>Final Answer: The length of each cable was 5.6 ft or just 5.6 ft.</u>
Answer:
True
Step-by-step explanation:
True
Answer: 31%
Step-by-step explanation:
Formula : Percent of the variability =
, where = Coefficient of Determination.
SSR = sum of squares of regression
SST = total sum of squares
is the proportion of the variation of Y that can be attributed to the variation of x.
As per given , we have
SSR = 14.55
SST= 46.8
Then, the percent of the variability in y that can be explained by variability in the regression model =
Hence, the percent of the variability in y that can be explained by variability in the regression model = 31%
Answer:
10.5 inches
Step-by-step explanation:
250% = 250/100 = 2.5
The plant grew 2.5 times its height in 5 weeks.
Be careful with the way you interpret "The plant grew by 250% of its height after 5 weeks." It means that in 5 weeks, the plant grew an amount equal to 2.5 times the original length of the plant. It does not mean that the total height at the end of 5 weeks was 2.5 times the original height.
growth is 5 weeks: 250% of 3 inches = 2.5 × 3 inches = 7.5 inches
height after 5 weeks: 3 inches + 7.5 inches = 10.5 inches
