Answer:
Positive
Step-by-step explanation:
As height is increasing, shoe size is also increasing (positive slope)
Negative correlation is when one variable increases and the other decreases (negative slope)
Answer:
x = 0
Step-by-step explanation:
Subtract 25x^2 from both sides
24x^2 + bx^2 - 25x^2 - 25x^2
Simplify
bx^2 - x^2 = 0
Factor bx^2 - x^2: x^2(b - 1)
bx^2 - x^2
Factor out common term x^2
= x^2 (b - 1)
x^2(b - 1) = 0
Using the Zero Factor Principle: If ab = 0 then a = 0 or b = 0
x^2 = 0
Apply rule x^n = 0 x = 0
x = 0
Step-by-step explanation:
2 + 3 × (8 + 53 ÷ 1)
we first work out the equation in the brackets
so...
(8 + 53 ÷ 1)
division comes first so we divide 53÷1 which is 1 so the equation looks like this:
(8+53)
we work this out and get
61
then we work the rest out
2 + 3 × <u>61</u>
multiplication comes first so...
3×61= 183
and
2+ 183= 185
Therefore 2 + 3 × (8 + 53 ÷ 1)= <u>185</u>
Hope this helped- have a good day bro cya)
