6 gallons, if there is 216 gallons in 36 tubs you have to take 216÷36 to get 6 gallons. To check your answer you can take 36 × 6
The answer is option A "Correlation, because time of day doesn't cause a person to run faster or slower." It's completely logic that the time of day doesn't affect the persons speed it's how fit the person that person is would effect his or her speed. Correlation is two data sets that are close together and are connected on a graph.
Hope this helps!
Set it up 180=(7x+10)+ z because angle b is on the flat line and then solve for x (180-10, then 170/7) and you’ll get the value of x and from there you can put it in all
Answer:
If x = -2, -1, 0, 1, then (In this order) y = 7, 5, 3, 1
Step-by-step explanation:
If you put in each value of "x" into the equation, you'll get the appropriate "y".
y= -2(-2)+3
y= 4+3
y= 7
y= -2(-1)+3
y= 2+3
y= 5
y= -2(0)+3
y= 0+3
y= 3
y= -2(1)+3
y= -2+3
y= 1
Answer:
Assuming ages are normally distributed, the 98% confidence interval for the population average age is [26.3, 35.7].
Step-by-step explanation:
We have to construct a 98% confidence interval for the mean.
The information we have is:
- Sample mean: 31
- Variance: 49
- Sample size: 15
- The age is normally distributed.
We know that the degrees of freedom are
Then, the t-value for a 98% CI is t=2.625 (according to the t-table).
The standard deviation can be estimated from the variance as:
The margin of error is:
Then, the CI can be constructed as:
