A quadrilateral has angles that measure 60°, 95°, and 150°. What is the measure of the fourth angle?

A.
25°

B.
55°

C.
85°

D.
125°

Answers

Answer 1
Answer: The sum of all angles of a quadrilateral is equal to 360º.

x=fourth angle;
Therefore:

x+60º+95º+150º=360º
x=360º-60º-95º-150º=55º

Answer: B. 55º

A container contains balls numbered from 1 through 55. A ball is drawn randomly and replaced. Then a second ball is drawn randomly. What is the probability that the first ball is number 9 and the second ball is number 41?

Answers

Answer:

1/3025

Step-by-step explanation:

Prob. of getting a 9 is 1/55; likewise for 41. multiply the 2 probs. together. (1/55)^2=1/3025≈0.00033057851

Final answer:

The probability of drawing ball number 9 first and then drawing ball number 41 from a container of balls numbered 1 to 55, with replacement is 1/3025.

Explanation:

The question pertains to the field of probability in Mathematics. It is asking for the probability of first drawing ball number 9 and then drawing ball number 41 from a container that contains balls numbered from 1 to 55. Since the ball is replaced after the first draw, the total number of possibilities remains the same for both draws. Therefore, the individual probability of drawing either one of those balls at a certain draw is 1/55.

Given that these are independent events, we multiply the probabilities. Hence, the probability of drawing ball number 9 first and then drawing ball number 41 is: P(9 and 41) = P(9) x P(41) = (1/55) x (1/55) = 1/3025.

JoAnne is depositing money into the bank account.After 3 months there is $150 in the account.After 6 months, there is $300 in the account.Find the constant rate of change of the account.

Answers

The constant rate of change for the account is +50.
If JoAnne started off with $150 at three months, she would go up by $50 each month after that to get to 300.
Month 4: 150+50=200
Month 5: 200+50=250
Month 6: 250+50=300

Answer:

I believe that it is 150 per month but im not sure

Step-by-step explanation:

150 * 3 = 300
