Step-by-step explanation:
what is the measure of angle b
Answer:
34
Step-by-step explanation:
A triangle will add up to a degree of 180, so if you add those 2 angles then subtract it from 180 you will get the answer. So, 115+31=146 then 180-146=34
So the answer is 34
Answer:
b = 34 degrees
Step-by-step explanation:
*triangles have an interior angle of 180 degrees
to find b, take the known angles (115 and 31) add them together and subtract the sum from 180:
⇒ 180 - (115 + 31)
solve:
⇒ 180 - 146 = 34
b = 34

Ivy is in Las Vegas and bet on her favorite team, the Denver Dragons, to beat the Seattle Sea Turtles. If the Denver Dragons win, she will win 10 dollars. If the Seattle Sea Turtles win, she will lose 11 dollars (the extra dollar is commission). Ivy estimates that there is a 50% chance of the Denver Dragons winning (there cannot be a tie). Find the expected return of placing this bet.
Answer: -0.5
Step-by-step explanation:
5 + (-5.5) = -0.5 dollars
The expected return of placing this bet is -0.5 dollars.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favorable outcomes to all outcomes.
To calculate the expected return of this bet, we need to consider the possible outcomes and their probabilities. There are two possible outcomes:
The Denver Dragons win with a probability of 0.5. In this case, Ivy will win 10 dollars.
The Seattle Sea Turtles win with a probability of 0.5. In this case, Ivy will lose 11 dollars.
To calculate the expected return, we multiply each outcome by its probability and sum the results.
Expected return = (0.5 x 10) + (0.5 x -11)
Expected return = 5 - 5.5
Expected return = -0.5
Therefore, the expected return of placing this bet is -0.5 dollars, which means that over the long run, Ivy can expect to lose an average of 50 cents every time she places this bet.

1. Forty randomly-selected members of a high school music program were asked to report the number of hours they spend practicing each week. If you were to compute the mean number of hours, would you answer be a parameter or a statistic? Explain.
===========================================================
Explanation:
The fact that we have the phrasing "randomly-selected" in there is a big clue that we are working with a sample, and not a population. If 40 people represented the population, then we wouldn't be randomly selecting anyone. Everyone would be surveyed. No random process needed. We don't need to worry about the order of those surveyed.
However, we are applying a random selection process to form this sample. A statistic is some value that measures a sample. For instance, xbar is the sample mean which is a sample statistic. The xbar value estimates mu, which is a greek letter. Mu is the population mean and a population parameter.
To remember the difference between the two terms parameter and statistic, one useful memory trick is to think of it like this:
Statistic and sample both start with sPopulation and parameter both start with pAs the name "statistics" implies, it is the study of how to estimate a population based on a sample. After gathering the sample, we compute a statistic, which in turn estimates a parameter. So that explains why your math course and textbook has that label.

I need help and please give me an understandable answer because I need to go to bed right now. I used 31 and 40 feet and none of them worked
Answer:
35 feet
Step-by-step explanation:
We'll begin by calculating the resultant for you and your friend.
For you:
R² = 12² + 9²
R² = 144 + 81
R² = 225
Take the square root of both side
R = √225
R = 15 feet
For your friend:
R² = 16² + 12²
R² = 256 + 144
R² = 400
Take the square root of both side
R = √400
R = 20 feet
Finally, we shall determine the distance between you and your friend.
The distance between you and your friend is obtained by adding your resultant and that of your friend together i.e
You resultant = 15 feet
Your friend's resultant = 20 feet
Distance between you and your friend = 15 + 20 = 35 feet.
Therefore, you threw the baseball 35 feet away from your friend.

tmara is making a medium length necklace. write an expression that shows how nuch it will cost tamara for the chain,pendant,and b beads that cost $0.25 each.Then find the total cost of the necklace if tamara uses 30 beads.
Answer:
1/4(n), $7.50
Step-by-step explanation:
Expanded: cost = 0.25 * chains + 0.25 * pendants + 0.25 * beads
Simplified: c = (1/4)(total number of items)
Expression only: 1/4n where n = # chains + # pendants + # beads purchased
Total cost of 30 beads = 1/4(30) = 7.5 = $7.50

Given:
Account balance for:
Month 1 = $1285.12
Month 2 = $961.36
Month 3 = $1132.63
Required:
Average balance of account
SOLUTION:
Average balance of account = sum of account balance for the 3 months ÷ 3
The month in which the balance of Account A is become equal to the balance of Account B is 15th months.
How to find unknown values?Unknown variables are used to find the unknown values of the problem using the algebraic expressions.
The table shows the balances of two bank accounts for 3 months.
Month Account A Account B 0 $50 $350 1 $85 $365 2 $120 $380The amount in account A is growing with $35 each month. Thus, the amount in this account in nth month is,
[tex]50+35n[/tex]
The amount in account B is just growing with $15. Thus, the amount in this account in nth month is,
[tex]50+15n[/tex]
Let the balance of Account A be equal to the balance of Account B iin n month. Thus,
[tex]50+35n=350+15n\\35n-15n=350-50\\20n=300\\n=\dfrac{300}{20}\\n=15[/tex]
Thus, the month in which the balance of Account A is become equal to the balance of Account B is 15th months.

Find the value of x.
Answer:
80°
Step-by-step explanation:
42° + 58° + x = 180° [Angle sum property of triangle]
=> 100 + x = 180
=> x = 180 - 100
=> x = 80 (Ans)
Step-by-step explanation:
58° + 42° + x = 180° -- (Δ sum property)
100° + x = 180°
x = 180° - 100°
x = 80°
