Positive correlation is a relationship between two variables in which both variables move in tandem—that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.

Answer:

x = 68°

Explanation:

given ∠CBE = 22°
∠ABD is parallel to ∠CBE, thus has same angle of 22°
∠ADB is right angle and thus has 90° angle.
total sum of interior angles in triangle is 180°

We can find x by:

x + 90° + 22° = 180°

x + 112° = 180°

x = 180°- 112°

x = 68°

Answer:

PLEASE BUY ME BITEABLE ACCOUNT. COSTS 19 DOLLARS! PLEASE ANYONE!

Step-by-step explanation:

To find how many licks she does to 1 lollipop, 54 divided by 3 which is 18. So, 18 licks/lollipop. 36/18=2. Which means Olivia licks 2 lollipops in 36 licks. To find 5 lollipops, 18*5=90. She licks 5 lollipops in 90 licks.
