1. The mean of all the numbers is 41.
5. Median : 52
To see if these ratios make a proportion let us first change them into fractions
= 4:10 = 4/10 = 4 ÷ 2 / 10 ÷ 2 = 2/5
= 6:15 = 6/15 = 6 ÷ 3 / 15 ÷ 3 = 2/5
= Since both these ratios are getting simplified into a same fraction , they are proportional .
Therefore , 4 : 10 :: 6 : 15 ( 4 : 10 is proportional to 6 : 15 )
It is just 4 x 4 for each and everyside
Answer:
it has no solutions
Step-by-step explanation:
y = mx + b
y = -5x - 1......slope here is -5 and y int is -1
y = -5x + 7....slope here is -5 and y int is 7
FOIL = first, outside, inside, last
(x - 2)(x - 3)
x^2 -3x - 2x + 6
x^2 - 5x + 6
