Answer:
50% probability that a randomly selected respondent voted for Obama.
Step-by-step explanation:
We have these following probabilities:
60% probability that an Ohio resident does not have a college degree.
If an Ohio resident does not have a college degree, a 52% probability that he voted for Obama.
40% probability that an Ohio resident has a college degree.
If an Ohio resident has a college degree, a 47% probability that he voted for Obama.
What is the probability that a randomly selected respondent voted for Obama?
This is the sum of 52% of 60%(non college degree) and 47% of 40%(college degree).
So
50% probability that a randomly selected respondent voted for Obama.

Answer:
y = (1/2)x - (15/2)
Step-by-step explanation:
goal: to rearrange the expression such that it is in the form
y = f(x); where f(x) is an expression in terms of x
given:
x - 2y = 15 (subtract x from both sides)
-2y = 15 - x (multiply both sides by -1 to make left side positive)
2y = -15 + x (divide both sides by 2 and rearrange)
y = (1/2)x - (15/2)
Answer: Ned received 86 Points overall on the test and Ned lost 24 points overall on his test.
Step-by-step explanation: Ned got 19 questions correct and 6 questions incorrect. He as well got 10 bonus points for answering a bonus question correctly. We know each of the questions on the test (excluding the bonus question) is worth 4 points.
If Ned got 19 questions correct that means 19 x 4 = he received 76 points.
If Ned got 6 questions incorrect that means 6 x 4 = he lost 24 points.
If Ned got 1 question correct that is worth 10 points, that means he got an additional 10 points to his score.
We can add the amount of points Ned scored to the amount of bonus points he earned; 76 + 10 = 86 points total on his test.
