Answer:
(- 4, 1 )
Step-by-step explanation:
Given the 2 equations
y = x + 5 → (1)
x - 5y = - 9 → (2)
Substitute y = x + 5 into (2)
x - 5(x + 5) = - 9 ← distribute and simplify left side
x - 5x - 25 = - 9
- 4x - 25 = - 9 ( add 25 to both sides )
- 4x = 16 ( divide both sides by - 4 )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (1)
y = - 4 + 5 = 1
Solution is (- 4, 1 )
Hello!
The mean is the average. The median is the middle number of the data set, in terms of quantity. The mode is the number that appears the most. The range is the difference between the largest and smallest numbers in the set.
Therefore, our answers are below.
Range: Difference between largest and smallest data piece.
Median: Middle value of a set of data
Mode: most commonly occurring number(s)
Mean: the sum of the data divided by the quantity of the data items.

Answer:
The player will recieve $2.
Step-by-step explanation:
Since we are not told what color ball you chose at random, and instead are asked to find the expected value. Then the expected ball color would be the ball with the highest probability of getting chosen.
Therefore, we need to find the probability of each color ball inside the bag. According to the question there are,
2 red + 3 white + 5 blue = 10 total balls
So the probabilities would be the following,
- Red:
- White:
- Blue:
So we can see that the ball with the highest probability of getting picked is the blue ball. Since the <u>Blue ball has a value of $2,</u> then the player will recieve $2.
