Answer:
6 = 1(3) + b
Step-by-step explanation:
this is following the equation y = mx + b, so you can just take the y and x of the point and plug them into this equation, along with the slope (m)
Hello there!
3. The questions asks for the amount of simple interest. The formula for simple interest is prt, where p = principal, r = rate, t = time. In this case, we are talking about 3 of them. 25,000 * 3 is 75,000. Now, let's multiply that number by 3% to find the amount of interest. 75,000 * 3% (0.03) is 2,250. Because this is only for one year, the number remains the same, so we don't have to multiply anything. There. The Branson family earns $2,250 in interest in one year. The answer is C.
4. Okay. For this inequality, we already have it set up. All we have to do is divide each side by 4 to isolate the x. 4x/4 cancels out. 22/4 is 5.5. There. x ≥ 5.5. The answer is B.
5. For this one, she hits the ball 22% of the time. To find out how many hits she will make, all you have to do is multiply the times at bat by 22%. In this case, she's at the bat 50 times. 50 * 22% (0.22) is 11. There. She will get about 11 hits. The answer is A.
Answer:
0.6946 = 69.46% probability that a randomly selected Republican voter from the exit poll is from a household that makes at least $50,000.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Republican
Event B: From a household that makes at least $50,000.
Probability of Republican:
43% of 36%(makes less than $50,000).
55% of 64%(makes more than $50,000).
So
Republican and from a household that makes at least $50,000.
55% of 64%. So
What is the probability that a randomly selected Republican voter from the exit poll is from a household that makes at least $50,000?
0.6946 = 69.46% probability that a randomly selected Republican voter from the exit poll is from a household that makes at least $50,000.
