Y = 3x + 48 where x is your number of years. I got 48 by multiplying 4 and 12 since there are 12 inches in a foot. (:
Answer:
FALSE
2.48 is greater than 2.4 because of the 8 at the end
The correlation coefficient between two variables, r, is always going to be between -1 and 1.
- If the correlation coefficient is 0, means that there is no strong correlation relationship in one direction or the other direction.
- If the correlation coefficient is -1, means that these two variables move in opposite directions.
- If the correlation coefficient is 1, means that these two variables move in the same direction.
Answer:
I only know how to solve it, it is -3
Step-by-step explanation:
-8x+3> or = 18-3x
3>or= 5x+18
-15> or = 5x
x>or=-3
Answer:
Step-by-step explanation:
shirt = x, pants: y
Katie equation: 3x + 2y = 80, Erin equation: 3x + 4y = 116
3x + 2y = 80
3x = 80 - 2y
x = 80/3 - 2y/3
3(80/3 - 2y/3) + 4y = 116
80 - 2y + 4y = 116
80 + 2y + 116
2y = 36
y = 18, pants cost $18
3x + 4(18) = 116
3x + 72 = 116
3x = 44
x = 14.66... (66 is repeating), shirts cost $14.66
check work:
Katie: 3(14.66) + 2(18) = 79.98 which is roughly 80.
