Explanation:
If y has an exponent of 2, 4, 6, etc (basically any even number) then it leads to having inputs with multiple outputs.
Consider something like y^2 = x. If x = 100, then y = 10 or y = -10 are possible. A function can only have exactly one y output for any valid x input. Similar issues happen for things like y^4 = x and so on. So this is why A and C are not functions.
The other equations do not have y values with such exponents, so we can solve for y and have each x input lead to exactly one y output. Therefore, they are functions.
To solve this question, you need to first look at the total amount of birds and then at the percentage of the blue jays that fed on the bird feeder out of all the other birds.
To calculate the total you add them all together:
59+68+12+1 = 140 birds
Then the percentages of the blue jays that fed on his bird feeder are:
59/140 *100 = 42.143%
You want to see how many blue jays we can expect to see out of 300 birds.
So you divide 300 by 100 to see what 1% is = 3 birds
Then you multiply this amount (1% = 3 birds) by 42.134% which is the percentage of blue jays we can expect to see out of the 300 birds.
3*42.134 = 126.43
You round this off to 126 because you cant expect to see half a bird. Even if the answer had been 126.9, you would have rounded it of to 126 because no matter how close it is to the next whole number; you either have a whole bird or you don't.
Final Answer = 126

Answer:
$93.72
Step-by-step explanation:
To be able to find how much is deducted from our paycheck monthly, we have to compute for the total amount left to pay for the health insurance.
Insurance = $4500
Company % = 75% or 0.75
Total amount left = $4500- $4500x0.75
Total amount left = $1125
Now that we know the total amount left, we simply divide the total by 12 to find the monthly payments.
Monthly Payment = $1125/12
Monthly Payment = $93.72
So a total of $93.72 will be deducted from our monthly paycheck for the health insurance.
