A bag contains 10 coloured balls. 5 of them are red and 3 of them are blue. A ball is taken from the bag at random, then replaced. A second ball is then selected at random. Find the probability that the first ball is red and the second ball is blue.
The probability that the first ball drawn is red and the second ball drawn is blue is 3/20.
The probability that the first ball drawn is red and the second ball drawn is blue, we need to multiply the probability of drawing a red ball on the first draw by the probability of drawing a blue ball on the second draw.
Given that there are 10 balls in total, with 5 red balls and 3 blue balls, the probability of drawing a red ball on the first draw is 5/10 = 1/2.
Since the ball is replaced after the first draw, the total number of balls remains the same for the second draw.
The probability of drawing a blue ball on the second draw is also 3/10.
To find the probability of both events occurring (the first ball being red and the second ball being blue), we multiply the probabilities:
Probability = (Probability of drawing a red ball) × (Probability of drawing a blue ball)
= (1/2) × (3/10)
= 3/20

Sam and Pam's pennies add up to 22. Same has 1 more penny than twice Pam's pennies. How many pennies do Sam and Pam have?
Answer:
pam has x = 7 pennies
sam has 2x + 1 = 14 + 1 = 15 pennies
Step-by-step explanation:
let's take the number of pennies that pam owns be x
sam's pennies = 2× ( pam's pennies ) + 1
=》2x + 1
if the total pennies owned by both = 22
then,
x + 2x +1 = 22
3x = 22 - 1
x = 21 ÷ 3
x = 7
so, pam has x = 7 pennies
sam has 2x + 1 = 14 + 1 = 15 pennies
Identify the percent of change as an increase or a decrease. 4/5 to 3/5 Increase Decrease Find the percent of change. Round to the nearest tenth of a percent if necessary.
The required percent of change from 4/5 to 3/5 is a decrease of 25%.
What is the percentage?The percentage is the ratio of the composition of value to the overall composition of value multiplied by 100.
Here,
The fraction 4/5 is greater than the fraction 3/5, so the change from 4/5 to 3/5 represents a decrease.
To find the percent of change, we first need to find the amount of change. We can do this by subtracting the original value (4/5) from the new value (3/5),
3/5 - 4/5 = -1/5
The amount of change is -1/5. To express this as a percent, we can use the formula.,
Percent change = (amount of change / original value) * 100%
Substituting the values we have,
Percent change = (-1/5 / 4/5) * 100%
Percent change = -0.25 * 100%
Percent change = -25%
Therefore, the percent of change from 4/5 to 3/5 is a decrease of 25%.

Each of students reported the number of movies they saw in the past year. Here is what they reported. 17,19,10,4,16,20
Answer:
14.3
Step-by-step explanation:
What you would do is add all 6 numbers together. After finding the sum, divide by 6. The 6 represents the amount of numbers in the data set. So you would find 86/6 and get 14.3333. That would be rounded to 14.3. Hope this helped!

State the domain and range of both the function and the inverse function. f(x) = 8 x + 8 f -1(x) = Domain of f(x): Range of f(x): Domain of f -1(x): Range of f -1(x)
Answer:
[tex]f^{-1}(x) = \frac{x+8}{8}[/tex]
Domain of f(x): All real values.
Range of f(x): All real values.
Domain of f -1(x): All real values.
Range of f -1(x): All real values
Step-by-step explanation:
We are given the following function:
[tex]f(x) = 8x + 8[/tex]
Since it is a line, we have that both the domain is the range is the real set.
Inverse function:
The domain of the inverse function is the range of the original function, and the range of the inverse function is the domain of the original function.
Finding the inverse function:
Exchange x and y in the original function, and isolate y. So
Original
[tex]y = 8x + 8[/tex]
Exchanging:
[tex]x = 8y - 8[/tex]
Isolating y:
[tex]8y = x + 8[/tex]
[tex]y = \frac{x+8}{8}[/tex]
[tex]f^{-1}(x) = \frac{x+8}{8}[/tex]

Answer:
10a. No
10b. No
10c. Yes
10d. Yes
Step-by-step explanation:
10a. This equation does not because 3/4 x 8 = 6 and not 9.
10b. This equation doesn’t because 3x8 does not equal 28.
10c. This equation does because 5 x 8 = 40 which means y = 8.
10d. This equation does because 8/2 = 4. Fractions are just division problems and 8 divided by 2 equals 4, meaning y = 8 was n this equation.

the temperature fell 16 degrees fahrenheit from 50 to 34 degrees in 10 hours. How much would the temperature fall over 15 hours if the pattern continued?
Answer:
[tex]x = 24\ degrees[/tex]
Step-by-step explanation:
Given
16 degrees = 10 hours
Required
Determine the change over 16 hours
Let the change be represented with x,
So, we have:
16 degrees = 10 hours
x = 15 hours
Cross Multiply:
[tex]x * 10\ hours = 16\ degrees * 15\ hours[/tex]
[tex]x * 10 = 16\ degrees * 15[/tex]
Divide through by 10
[tex]x = \frac{16\ degrees * 15}{10}[/tex]
[tex]x = 16\ degrees * 1.5[/tex]
[tex]x = 24\ degrees[/tex]

Mary’s annual salary is $38,500 plus 22% in employee benefits. Her yearly job expenses are: uniforms, $500; transportation and parking, $5,350; and tools and certifications, $1,200. What are her net job benefits?
Answer: $39,920
Step-by-step explanation:
Her net job benefits would be the benefits and salary she receives less the expenses she incurs in relation to the job:
= Salary + Benefits - Uniforms - Transport - Tools
= 38,500 + (22% * 38,500) - 500 - 5,350 - 1,200
= 46,970 - 7,050
= $39,920
