Represent the width as an inequality
First, we represent the area as an inequality.
max as used above means less than or equal to.
So, we have:
The area of a rectangle is:
So, we have:
Substitute 10 for L
Divide both sides by 10
Answer:Graph A
Step-by-step explanation: -3 is your y intercept and your slope is up 2 over 1.
Answer:
N< 10 and N>4
Step-by-step explanation:
-2+3n< 28. =. 3n < 30. =. N < 10
+2. +2 ÷3. ÷3
6n - 7 > 17. =. 6n > 24. =. N > 4
+7. +7. ÷ 6. ÷ 6
Answer:
The correlation coefficient of the data is -0.13, which means as the weekly mileage increases, it has no effect on the average mile time.Step-by-step explanation:
The correlation coefficient of a data set describes how closely related two variables are. Correlation coefficients close to positive 1 show a strong positive correlation, while correlation coefficients close to negative 1 show a strong negative correlation. When a correlation coefficient is close to 0, it shows no correlation between the data.
For the given data set, calculate the correlation coefficient using technology.
This r-value is closer to 0 then it is to -1. Thus, the correlation coefficient of the data is -0.13, which means as the weekly mileage increases, it has no effect on the average mile time.
