Answer:
If f(x) = +4, which of the following is the inverse of f(x)?
O A. ƒ˜¹(x) = 2(2+4)
B. ƒ˜¹(x) = 7(2-4)
C. ƒ˜¹(x) = 7(2+4)
D. f¯¹(x) = ²(2-4)
Step-by-step explanation:
The mean of the data set is 4. Find the absolute deviation of each of the red data values
The absolute deviation of 0 is
The absolute deviation of 3 is
The absolute deviation of 7 is
The absolute deviation of each of the data values are 4, 1 and 3 respectively.
Absolute deviationThe absolute deviatuon gives the distance of any given value in a dataset to the mean value. The absolute deviation is always positive as it does not consider the side to which the value belongs.
Absolute deviation = |value - mean|
Mean = 4
Absolute deviation of 0 = |0 - 4| = 4
Absolute deviation of 3 = |3 - 4| = 1
Absolute deviation of 7 = |7 - 4| = 3
Hence, The absolute deviation of each of the data values are 4, 1 and 3 respectively.

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that makes skateboards can be modeled by the polynomial 2x3 + 30x – 130. The cost, in dollars, of producing the skateboards can be modeled by 2x3 – 3x – 520. The variable x represents the number of skateboards sold.
what expression would represent profit.
The expression would represent profit is expressed as the polynomial, 33x + 390.
How to Find the Expression of a Model?To represent the profit, we need to subtract the cost from the revenue. The revenue is given by the polynomial 2x³ + 30x - 130, and the cost is given by the polynomial 2x³ - 3x - 520.
Therefore, the expression representing profit can be obtained by subtracting the cost from the revenue:
Profit = (2x³ + 30x - 130) - (2x³ - 3x - 520)
Simplifying the expression, we have:
Profit = 2x³ + 30x - 130 - 2x³ + 3x + 520
Combining like terms, we get:
Profit = (2x³ - 2x³) + (30x + 3x) + (520 - 130)
Simplifying further:
Profit = 33x + 390

The probability of rain on a particular day is 0.4. If it rains, the probability that Pablo goes jogging is 0.15. If it does not rain, the probability that he goes jogging is 0.85. What is the probability that Pablo goes jogging on that day?
The probability that Pablo goes jogging on that day is 0.57 or 57%.
Given that,
The probability of rain on a particular day is 0.4.
When it rains, the probability that Pablo goes jogging is 0.15.
And, it does not rain, the probability that he goes jogging is 0.85.
Now, The probability for Pablo goes jogging on that day is find as,
The probability that it rains and Pablo goes jogging,
0.4 x 0.15 = 0.06
And, The probability that it does not rain and Pablo goes jogging,
0.6 x 0.85 = 0.51
Therefore, the total probability that Pablo goes jogging on that day is:
0.06 + 0.51 = 0.57
Thus, the probability that Pablo goes jogging on that day is 0.57 or 57%.

The sample mean is more than the population mean by 4.33.
To determine how much the sample mean is more than the population mean, we need to calculate the mean of the entire population and the mean of the given sample.
The population data set is: 4, 6, 7, 11, 12, 18, 26, 23, 14, 31, 22, and 12.
To find the population mean, we sum up all the values and divide by the total number of values:
Population Mean = (4 + 6 + 7 + 11 + 12 + 18 + 26 + 23 + 14 + 31 + 22 + 12) / 12
Population Mean = 176 / 12
Population Mean = 14.67 (rounded to two decimal places)
Next, let's calculate the mean of the given sample: 11, 31, 22, and 12.
Sample Mean = (11 + 31 + 22 + 12) / 4
Sample Mean = 76 / 4
Sample Mean = 19
To determine how much the sample mean is more than the population mean, we subtract the population mean from the sample mean:
19 - 14.67 = 4.33

There are 27 balls in a pouch. 9 green, 3 blue, 7 red, & the rest are purple. What is the
probability of a green or blue ball being chosen at random?
The probability for this event is 0.44
How to find the probability?All the balls have the same probability of being selected at random, then the probability that the ball chosen at random is either green or blue, is equal to the quotient between the number of balls green or blue and the total number.
The total number is 27.
9 are green.
3 are blue.
Then the probability is:
P = (9 + 3)/27

Given: p || q, and r || s.
Linear pair theorem that is angle 1 is supplementary to angle 2 moves down to angle 2 equals angle 6. As for parallel lines cut by a transversal, corresponding angles are congruent. This moves down to blank box with question mark.
Prove: ∠1 and ∠14 are supplementary angles.
Two vertical parallel lines p and q runs through two horizontal parallel lines r and s to form 16 angles numbered from 1 to 16.
What is the next step in the proof? Choose the most logical approach.

What is corresponding angles theorem?In Mathematics and Geometry, corresponding angles theorem can be defined as a postulate (theorem) which states that corresponding angles are always congruent when the transversal intersects two (2) parallel lines.
This ultimately implies that, the corresponding angles will be always equal (congruent) when a transversal intersects two (2) parallel lines.
By applying corresponding angles theorem to parallel lines p and q, and parallel lines r and s, we can logically deduce the following congruent angle:
