Answer:

x=15

Step-by-step explanation:

5x+25=100

Subtract 25 from both sides.

5x+25−25=100−25

5x=75

Divide both sides by 5.

5x÷5=75÷5

x=15

\(5x+25=100\\x=\)

Subtract 25 from both sides:

\(5x+25-25=100-25\\5x=75\)

The solution set of the equation is: x = -3, x = 3.

Given the equation, x² + 12 = 21, the solution set is the possible value of x that will make the equation true. To find the values of x, do the following as shown below:

x² + 12 = 21

Subtract 21 from both sides of the equation

x² + 12 - 21 = 21 - 21

x² + 12 - 21 = 0

x² - 9 = 0

Find the difference of the two squares

(x + 3)(x - 3) = 0

x = -3

Answer:

usage patterns are a variable used in market segmentation.

Step-by-step explanation:

Usage patterns are a variable used in behavioral segmentation.

Behavioral segmentation is a marketing strategy that divides a market into different segments based on consumer behavior, specifically their patterns of product usage, buying habits, and decision-making processes. This segmentation approach recognizes that customers with similar behavioral characteristics are likely to exhibit similar preferences and respond in a similar manner to marketing initiatives.

Usage patterns, as a variable, help marketers understand and classify customers based on how they interact with a product or service. This can include factors such as the frequency of product usage, the amount of product used, the timing of purchases, brand loyalty, product benefits sought, and other behavioral indicators.

By analyzing usage patterns, marketers can identify distinct segments within their target market and tailor marketing strategies to meet the unique needs and preferences of each segment. This enables companies to develop more targeted marketing campaigns, optimize product offerings, improve customer satisfaction, and drive customer loyalty.

Overall, behavioral segmentation, including the consideration of usage patterns, allows companies to better understand and connect with their customers by aligning their marketing efforts with specific behaviors and motivations.

Step-by-step explanation:

The environmental agency should sample at least 746 vehicles.

In order to determine how many cars should be sampled for a full investigation, we can use the formula for sample size:
n = (Z^2 * p * q) / E^2
where:
- n = sample size
- Z = the Z-score for the desired level of confidence (in this case, 1.645 for 90% confidence)
- p = the proportion of cars in the population with faulty emissions systems (which we can estimate as 12/60 = 0.2 based on the initial sample)
- q = 1 - p
- E = the desired margin of error (2% in this case, or 0.02)
Plugging in these values, we get:
n = (1.645^2 * 0.2 * 0.8) / 0.02^2
n ≈ 746
Therefore, the environmental agency should sample at least 746 vehicles for a full investigation in order to estimate the percentage of cars violating clean air emissions standards with a margin of error of 2% and 90% confidence.

The slope of the line passing through (-5, 1), (-6, 5), (-3, -7), and (-4, -3) is -4.

What is slope?

Slope is a measure of the steepness of a line on a graph. It describes the rate at which the y-coordinate of a line changes with respect to the change in the x-coordinate.

To find the slope of the line passing through the points (-5, 1), (-6, 5), (-3, -7), and (-4, -3), we can use the same formula:

slope = (change in y) / (change in x)

Again, we can choose any two points and find the change in y and change in x between them. The slope will be the same regardless of which two points we choose.

Let's choose the points (-5, 1) and (-6, 5) to start with:

change in y = 5 - 1 = 4

change in x = -6 - (-5) = -1

slope = 4 / (-1) = -4

Now let's choose the points (-3, -7) and (-4, -3):

change in y = -3 - (-7) = 4

change in x = -4 - (-3) = -1

slope = 4 / (-1) = -4

Since the slope is the same for both pairs of points, we can conclude that the points lie on the same line.

Therefore, the slope of the line passing through (-5, 1), (-6, 5), (-3, -7), and (-4, -3) is -4.

The given statement "Stack algorithms can never exhibit Belady's anomaly" is True because stack algorithms, including LRU, do not exhibit Belady's anomaly due to their inherent properties that prioritize recently accessed pages and prevent increased page faults when the number of frames is increased.

Belady's anomaly is a phenomenon that occurs in certain page replacement algorithms used in computer systems, where increasing the number of allocated frames for a process can lead to an increase in the number of page faults. This anomaly is usually observed in algorithms like First-In-First-Out (FIFO) and Second Chance.

Stack algorithms, such as the Last-In-First-Out (LIFO) policy and the Least Recently Used (LRU) algorithm, do not exhibit Belady's anomaly due to their properties. In a stack algorithm, the most recently accessed pages are kept close to the top of the stack, while the least recently accessed pages are at the bottom.

The LRU algorithm, in particular, has been proven to be free from Belady's anomaly because it possesses the stack property. When a page is accessed, it is moved to the top of the stack, making it the most recently used page. If a new page needs to be loaded, the LRU algorithm will replace the page at the bottom of the stack, which is the least recently used page. Due to this behavior, adding more frames to the system will not cause an increase in the number of page faults.

Step-by-step explanation:

The given integral is: $$\int (-2x^2 + 500)dx$$

To solve the above integral, we integrate both terms separately. Using the integral formulas, $$\int x^n dx= \frac{x^{n+1}}{n+1}+ C$$$$\int kf(x)dx= k\int f(x)dx$$

where C is a constant of integration and k is a constant.

The integral $\int -2x^2 dx$ is:\begin{align*} \int -2x^2 dx &= -2\int x^2 dx\\&= -2\times \frac{x^{2+1}} {2+1} + C\\&= -\frac {2}{3}x^3+ C\end{align*}

The integral $\int 500 dx$ is:\begin{align*}\int 500 dx &= 500\int dx\\&= 500\times x + C\\&= 500x + C\end{align*}

Thus, the integral $\int (-2x^2 + 500) dx$ is:\begin{align*}\int (-2x^2 + 500) dx &= \int -2x^2 dx + \int 500 dx\\&= (-\frac {2}{3}x^3+ C_1) + (500x + C_2)\\&= -\frac {2}{3}x^3+ 500x + C\end{align*}

where C is a constant of integration and $C=C_1+C_2$.

X to the power of 3/10 multiplied by x to the power of 1/4.

When dividing x to the power of 1/2 by x to the power of 1/5, the quotient property states that the exponents 1/2 and 1/5 can be subtracted.

However, to add or subtract fractions, the denominators need to be the same. So, we can change 1/2 to 5/10 and 1/5 to 2/10. Now, we can subtract the exponents to get (5/10) - (2/10) = 3/10.

Finally, we can apply the power of a power property, which states that when multiplying two exponents, the exponents can be multiplied together.

Therefore, the final answer is x to the power of 3/10 multiplied by x to the power of 1/4.

Step-by-step explanation:

1120 divided by 32 is 35, I used a calculator. If you divide the cost by the quantity you will get the cost for one quantity

Let $C$ be the event that the camera gets a 10% discount, $G$ be the event that the game gets a 25% discount, and $N$ be the event that neither item gets a discount. Then the probability of each event is:

\begin{align*}

P(C) &= 0.35\cdot 0.1 = 0.035 \\

P(G) &= 0.05\cdot 0.25 = 0.0125 \\

P(N) &= 0.6\cdot 1 = 0.6

\end{align*}

The amount saved on the camera is $0.1\cdot 200=20$, and the amount saved on the game is $0.25\cdot 80=20$. So, we want to find the probability that either event $C$ or $G$ occurs. Since the events are mutually exclusive, we can use the addition rule:

$$

P(C\text{ or }G) = P(C) + P(G) = 0.035 + 0.0125 = 0.0475

$$

The amount saved in dollars at the cash register is $X = 20 + 20 = 40$. To find the probability that the total amount saved is $20$, we need to sum the probabilities of all the ways to get $X=20$. There are two ways to do this: either the camera gets a 10% discount while the game gets no discount, or the game gets a 25% discount while the camera gets no discount. Using the multiplication rule and the probabilities above, we have:

\begin{align*}

P(\text{camera gets 10% discount, game gets no discount}) &= P(C)\cdot P(N) = 0.035\cdot 0.6 = 0.021 \\

P(\text{game gets 25% discount, camera gets no discount}) &= P(G)\cdot P(N) = 0.0125\cdot 0.6 = 0.0075

\end{align*}

Therefore, the probability that the total amount saved is $20$ is:

$$

P(X=20) = P(\text{camera gets 10% discount, game gets no discount}) + P(\text{game gets 25% discount, camera gets no discount}) = 0.021 + 0.0075 = 0.0285

$$

So the chance you save a total of $20$ is $\boxed{0.0285}$.
