The measure of variation for a numerical data set describes how
the values of a number vary with the single number. This measurement shows the
difference in the properties of a certain number to the rest of the numbers in the
numerical data set.
Answer:
30
Step-by-step explanation:
Shoes + Shoes + Shoes = 30 (Shoes = 10)
Person + Person + Shoes = 20 (Person = 5)
Newspaper + Newspaper + Person = 13 (Newspaper = 4)
= Shoes + Person * Newspaper
= Person * Newspaper + Shoes
= 5 * 4 + 10
= 20 + 10
= 30
You’re solving for x, and you need to isolate x so it equals one number on the other side. Multiply by both sides by 14. 4x - 1x = -3, which reduces to 3x = -3, so x = -1. For 5, multiply both sides by 4. -3x + 1 = 2 which reduces to -3x = 1, so x = -1/3. For 6, multiply both sides by 4. x + 8 = 3. So x = -5. Make sure to check by plugging in x for each problem.
