Answer:
$1.20
Step-by-step explanation:
9.20 x 4 = 36.8
7.60 x 5 = 38
38 - 36.8 = 1.20
Answer:
She saves $1.2
Step-by-step explanation:
Given:
5 golf balls for $9.20 - Golf Central
4 golf balls for $7.60 - Strictly Golf
20 golf balls
Solution:
First divide 20 by 5 and 4
20 ÷ 5 = 4 (Golf Central)
20 ÷ 4 = 5 (Strictly Golf)
Now multiply 4 by 9.20 and 5 by 7.60
4 x 9.20 = 36. 80 or 36.8
5 x 7.60 = 38
Now subtract 38 to 36.8 to find how much will she save
38 - 36.8
= $1.2

How would you solve absolute value equations with "or" and "and"? Sometimes even with coefficients.
9514 1404 393
Explanation:
In general, a system of equations has a solution that satisfies all of the equations. That is, the solution set is the intersection (and) of the solution sets of the individual equations in the system. Equations involving the absolute value function are no different.
That being said, you need to consider the meaning of an equation involving the absolute value function.
The function itself is piecewise defined:
\(\displaystyle |x|=\left\{ {x, x\ge0} \atop {-x, x<0}} \right.\)
So, any equation involving the absolute value function automatically resolves to two equations, each with its own condition on the function value.
__
Example 1:
|x+1| > 3
is equivalent to the two disjoint conditional equations ...
(x +1) > 3 and (x +1) ≥ 0 . . . . OR
-(x +1) > 3 and (x +1) < 0
the first of these has the solution x > 2; the second of these has the solution x < -4. The solution set of this equation is the OR of the two solution sets:
x < -4 or x > 2
__
Example 2:
|x +1| < 3
is equivalent to the two disjoint conditional equations ...
(x +1) < 3 and (x +1) ≥ 0 . . . . OR
-(x +1) < 3 and (x +1) < 0
The first of these has the solution -1 ≤ x < 2, and the second of these has the solution -4 < x < -1. Again, the solution set of this equation is the OR of the two solution sets. However, we find we can write that union as a single compound inequality:
-4 < x < 2
__
When an absolute value equation involves more than one absolute value function, then the equation will probably resolve into multiple equations, each defined on its own domain. Sometimes keeping those domains straight can be tedious.
Above, we have considered inequalities. If you have an equation, you need to consider that it will likely resolve to two equations. The solution set will be the OR of the solutions to those two equations.
Example 3:
|x +1| = 3
is equivalent to the two conditional equations ...
(x +1) = 3 and (x +1) ≥ 0 . . . . OR
-(x +1) = 3 and (x +1) < 0
The first of these has the solution x = 2; the second has the solution x = -4. The solution set is the OR of these two solutions:
x = -4 or x = 2
__
The "and" condition restricts the domain of each of the individual pieces of the equation. The "or" condition applies to the collection of solutions that may exist in each of those restricted domains.
mplement the task of simulation in computation language of your choice to validate the central limit theorem (concept in §4.11)
The Central Limit Theorem is a fundamental concept in statistics that states that the sampling distribution of the mean of a random sample approaches a normal distribution as the sample size increases, regardless of the shape of the population distribution.
To validate the Central Limit Theorem, you can follow these steps in any computation language of your choice:
1. Define the population distribution: Choose a probability distribution, such as a uniform, exponential, or binomial distribution, to represent the population from which samples will be drawn.
2. Generate random samples: Use the chosen distribution to generate random samples of different sizes. For example, you can generate 100 samples of size 10, 100 samples of size 30, and so on. Make sure to record the means of these samples.
3. Calculate the sample means: For each sample, calculate the mean by summing up all the values in the sample and dividing by the sample size.
4. Plot the sampling distribution: Create a histogram or a density plot of the sample means. This plot will show the distribution of the sample means.
5. Compare with the theoretical distribution: Overlay the theoretical normal distribution on the plot of the sample means. The mean of the sample means should be close to the mean of the population, and the shape of the distribution should resemble a normal distribution.
6. Repeat the process: Repeat steps 2-5 with different sample sizes to observe how the shape of the sampling distribution changes as the sample size increases. The Central Limit Theorem predicts that the distribution of the sample means will approach a normal distribution as the sample size increases.
By following these steps and comparing the distribution of the sample means with the theoretical normal distribution, you can validate the Central Limit Theorem in your chosen computation language.

Which of the sets of ordered pairs represents a function? (1 point)
P = {(6, −7), (3, −2), (−9, 2), (−5, −7)}
Q = {(−7, 8), (4, −6), (−3, 1), (1, 5)}
Answer:
Conclusion:
Both sets represent the function.
Step-by-step explanation:
We know that a function relates an input to an output.For example, a certain plant grows 10 cm each year. Thus, the height of the plant is associated with its age using the function
h (age) = age × 10
Thus, if the age of the plant is 2 years, the height is:
h(10) = 2 × 10 = 20 cm
Set P
P = {(6, −7), (3, −2), (−9, 2), (−5, −7)}
The set P represents the function because the function relates an input to an output. In other words, here each input is related to exactly one output.
The x-values are 6, 3, -9, and -5.
Thus, there are no duplicated inputs or x-values.
Therefore, the set P of ordered pairs represents a function.Set Q
Q = {(−7, 8), (4, −6), (−3, 1), (1, 5)}
The set P represents the function because the function relates an input to an output. In other words, here each input is related to exactly one output.
The x-values are -7, 4, -3, and 1.
Thus, there are no duplicated inputs or x-values.
Therefore, the set Q of ordered pairs also represents a function.Conclusion:
Both sets represent the function.

at a carnival game, the chance of winning a prize is 0.45. kylee plays the game 3 times. using the table, what is the probability that she wins at most 2 prizes?
The probability that Kylee wins at most 2 prizes in 3 attempts is 0.95625.
To answer this question, we can use the binomial distribution formula:
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)
where X is the number of times Kylee wins a prize, and P(X = k) is the probability of winning k prizes in 3 attempts.
Using the binomial distribution formula, we can calculate these probabilities using the following formula:
\(P(X = k) = (n choose k) × p^k × (1-p)^(n-k)\)
where n is the number of trials (in this case, 3), p is the probability of winning a prize (0.45), and k is the number of
successes we want to calculate the probability for.
Now, let's plug in the values for k = 0, 1, and 2:
\(P(X = 0) = (3 choose 0) × 0.45^0 × (1-0.45)^3 = 0.342
P(X = 1) = (3 choose 1) × 0.45^1 × (1-0.45)^2 = 0.4095
P(X = 2) = (3 choose 2) × 0.45^2 × (1-0.45)^1 = 0.20475\)
Now, we can add up these probabilities to find the probability that Kylee wins at most 2 prizes:
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.342 + 0.4095 + 0.20475 = 0.95625

The arithmetic mean of the monthly salaries of two people is $4360. One person earns $3479 per month. What is the monthly salary of the other person?
If arithmetic mean of the monthly salaries of two people is $4360. One person earns $3479 per month then the monthly salary of the other person is $5241
The arithmetic mean of the monthly salaries of two people is $4360
One person earns $3479 per month
We have to find the monthly salary of the other person
Arithmetic mean = a+b/2
4360 = 3479+b/2
4360×2 = 3479+b
8720 = 3479+b
Subtract 3479 from both sides
8720-3479 =b
$5241 =b
Hence, $5241 is the monthly salary of the other person.

Step-by-step explanation:
write the equation of a parabola with focus and directrix
The equation of a parabola with a given focus and directrix is:
x^2 - 2ax + 2by + (a^2 + b^2 - c^2) = 0
In this equation, (a, b) represents the coordinates of the focus, and c represents the y-coordinate of the directrix. This equation describes a parabola where all points on the parabola are equidistant from the focus and the directrix.
To write the equation of a parabola with a given focus and directrix, we can use the geometric definition of a parabola. A parabola is the set of all points that are equidistant from the focus and the directrix.
Let's assume the focus is denoted as F(a, b) and the directrix is a horizontal line given by y = c. The vertex of the parabola is at the midpoint between the focus and the directrix, which is V(a, (b + c) / 2).
The distance from any point (x, y) on the parabola to the focus F(a, b) is given by the distance formula:
sqrt((x - a)^2 + (y - b)^2)
The distance from the point (x, y) on the parabola to the directrix y = c is given by |y - c|.
According to the definition of a parabola, these two distances are equal. Thus, we can set up the equation:
sqrt((x - a)^2 + (y - b)^2) = |y - c|
Squaring both sides of the equation eliminates the square root:
(x - a)^2 + (y - b)^2 = (y - c)^2
Expanding and rearranging the terms:
x^2 - 2ax + a^2 + y^2 - 2by + b^2 = y^2 - 2cy + c^2
Simplifying and canceling out the y^2 terms:
x^2 - 2ax + a^2 + b^2 - 2by = c^2 - 2cy
Rearranging the terms to obtain the standard form of the equation:
x^2 - 2ax + 2by + (a^2 + b^2 - c^2) = 0
Thus, the equation of the parabola with focus F(a, b) and directrix y = c is given by:
x^2 - 2ax + 2by + (a^2 + b^2 - c^2) = 0
