Answer:
they made 5 pies
Step-by-step explanation:
total sold = 40
3 pies from the cafeteria times 5 cut pieces = 15
40 - 15 = 25
25 / 5 = 5
the expression is 5x + 15 = 40
5 is how many slices were cut
15 is the slices from the 3 from the cafeteria
40 is how many were sold
5 is how many were made
Answer:
1; -1
Step-by-step explanation:
As x approaches 0 from the left, the graph goes up to the point (0, 1), where the solid dot indicates that is the function definition for x=0.
As x approaches 0 from the right, the graph goes down toward the point (0, -1), to which it comes arbitrarily close. The limit from that direction is -1.
The two limits are +1 and -1.
Answer:
87.4
Step-by-step explanation:
Recall, that the average is simply the sum of all the scores divided by the number of individual scores
in this case,
the sum of scores = 87+94+76+86+94=437
the number of individual scores = 5
average = sum of scores / number of individual scores
= 437 ÷ 5
= 87.4
Answer:
21.16
Step-by-step explanation:
Starting from the theory we have the following equation:
Using the data supplied in the exercise, we have subtracting the mean and dividing by the standard deviation:
solving for "c", knowing that fi is a tabulating value:
therefore the value of c is equal to 21.16
