(d+6)^2=y or (d+6)(d+6)=y
(1/3)9^3 = (9/3)^3 = 3^3 = 27
Answer:
C. Bentley got $20 for her allowance.
Step-by-step explanation:
If Bentley was given $40 at first, then spent $10, we plot a line on the graph that decreases and then she receives $20. $20 is bigger than $10, therefore this is the scenario best represented by a linear increasing interval.
I hope this makes sense!! ^-^

Answer:
0.65
Step-by-step explanation:
Confidence interval can be calculated using the Mean and Margin of error with M±ME where
- M is the average expected cold days of typical cold.
- ME is the Margin of error for the confidence interval.
In the question it is given that the researchers reported a 95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.
The minimum value in the confidence interval is M-ME =6.9
The maximum value in the confidence interval is M+ME=8.2
Then we get 8.2-6.9=1.3=M+ME-(M-ME)=2× ME
From this we get ME=0.65
