The correct answer is choice D, or (-3, 2). We can tell because if we plot out the points, we go left 3, down 3 for (-3, -3), then right 7, down 3 for (7, -3), then right 7, up 2 for (7, 2), therefore the remaining point would have to be left -3, up 2, which is shown in choice D.
Hope that helped =)
Answer:
a. C = 7x
b. $1820
Step-by-step explanation:
Let the number of students the bus carries be x.
a. It costs $7 for every student that they bus.
Therefore, the cost of the school hiring the bus is:
C = 7 * x
C = 7x
b. To bus 260 students, then, the cost will be:
C = 7 * 260
C = $1820

48.16
Step-by-step explanation:
Answer: 0.4
Step-by-step explanation:
We know that the standard deviation of the sampling distribution of mean is given by:-

Given : Standard deviation : 
Sample size : n= 25
Then, the standard deviation of the sampling distribution of mean times will be :-

Hence, the standard deviation of the sampling distribution of mean times=0.4
