<span>a linear function from the real numbers to the real numbers is a function whose graph is a line in the plane</span>
Answer:
A
Step-by-step explanation:
In that example the plane is going up constantly whereas in example B the plane in going down, in example C the plane it going up but the stops and goes at the same speed, and in D the plane it once again going down.
Answer:
4 M + 2 N = 120
Step-by-step explanation:
If we name "M" the number of tables for four people, and "N" the number of tables for two people, then the total number of people to be seated using M tables (of four people) would be the product "4 * M".
Similarly, the total number of people to be seated if the owner has N number of two person tables, would be: "2 * N".
Therefore, if the owner has M four people tables and N two person tables, the total number of people seated at the restaurant would be the addition:
4 * M + 2 * N. Since he wants this number to be 120, we complete the equation making this expression equal to 120:
4 * M + 2 * N = 120
Answer:
yes
Step-by-step explanation:
|-12| = |12| they always equal to 12
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
