Answer:
-3 
= -3
Step-by-step explanation:
Add up the numbers on either side of the equal sign. If it helps, you can convert everything to improper fractions so that the math is easier.
Answer:
C
Step-by-step explanation:
Note that each of the y- coordinates is the x- coordinate raised to the power of 4.
(1, 1) → y = 
= 1
(2, 16) → y = 
= 16
(3, 81) → y = 
= 81
(4, 256) → y = 
= 256
(5, 625) → y = 
= 625
Thus the rule is y = 
→ C
The slope should be 3/2, since you rise 3 and go over 2
The formula of the measurement of an exterior angle of a regular polygon is
β = 360°/n
where β = exterior angle and n = number of sides
Therefore,
n = 360°/β = 360°/18° = 20 sides

Answer: 7/10</h3>
==========================================================
Explanation:
There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.
If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.
The empirical probability of it not raining on the first of May is therefore...
1 - (probability it rains)
1 - (3/10)
(10/10) - (3/10)
(10-3)/10
7/10
We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.
