2. 3876
EXPLANATION
1. We want to find the value of:
This is called "12 permutation 7"
Permutation function is defined as follows:
Therefore, we have that:
2. We want to find:
This is called "19 combination 15"
Combination function is defined as:
Therefore, we have that:
Answer:
median = 5
range = 2
mean = 11
Step-by-step explanation:
(-12 - 8)/(6 - 8) = -20/-2 = 10.
It's positive.
Answer:
Sample response:
To determine the relationship between quantities, you must determine what to do to the x-values to make them into y-values. The correct operation must turn every x-value into the corresponding y- value in the table. Once you know the relationship, you can use the same operation on all of the x-values that have unknown y-values.
OR:
In a table to get from x to y you have to multiply by a number. To find this you must divide x by y or y by x. So to get the missing quantities you must multiply the last known number by the number you found by dividing.
Answer: 1/2 and 3/6
