Answer: 40%
=========================================
Work Shown:
"given that it's a senior" is an important piece of info that tells us to only focus on the "seniors" column. The word "given" is an indication that we know this information 100%
There are 5 seniors (2+3 = 5) and 2 of them are male. So 2/5 = 0.40 = 40% of the seniors are male. The probability of selecting a male, if we know this person is a senior, is 40%
Answer:
y = -cos(2x)
Step-by-step explanation:
Mean/mid line: y = 0
It's a negative cos, with period pi.
So, y = -cos(2x)

Answer:
x=15 y=24
Step-by-step explanation:
This is because the rule is x goes up 3 y goes up 4
(9,12)->(x,20)
it skips one, so instead of adding 3 we add six
x=15
(15,20)->(18,y)
you follow the rule and 4.
Y=24
The ordered pairs ( 1 , 4 ) , ( 2 , 1 6 ) , ( 3 , 6 4 ) , ( 4 , 2 5 6 ) , ( 5 , 1 , 0 2 4 ) ( 1 , 4 ) , ( 2 , 1 6 ) , ( 3 , 6 4

Answer:
The rule is f(x) = 2^(2x).
Step-by-step explanation:
Note that 4 = 2^2, 16 = 4^2, 64 = 8^2, 256 = 16^2 and 1024 = 32^2
and the first numbers in the ordered pairs are 1 , 2 ,3, 4, 5
compare this with 2, 4 , 8, 16 , 32.
We see that the rule for this is 2^x where x is the sequence number.
So the rule for the original ordered pairs is (2^x)^2.
= 2^2x.
