Solve the system by substitution . 5x- y =21 x=2y -3
Answer:
(5,4)
Step-by-step explanation:
To solve a system of equations by substitution, you need to solve one of the equations for one variable (either x or y). In this case, we can solve the second equation for x: x=2y-3. Then substitute this expression into the first equation and solve for y: 5(2y-3)-y=21. Solving for y gives us y=4. Substitute this value back into the second equation and solve for x: x=2(4)-3=5. Therefore, the solution is (5,4).

a factorial design involves a) manipulating two or more independent variables. b) an inability to specify the overall effect of an independent variable. c) having multiple dependent measures. d) all of these
The correct answer is
(a) manipulating two or more independent variables.
A factorial plan could be a sort of test plan utilized in investigating to examine the impacts of two or more free factors on a subordinate variable.
In a factorial plan, analysts control each free variable over different levels to watch the one-of-a-kind impacts of each free variable and how they connected with each other to impact the subordinate variable.
For case, in a ponder examining the impacts of two autonomous factors (e.g., temperature and mugginess) on a subordinate variable (e.g., plant development), analysts may control the temperature at three distinctive levels (moo, medium, and tall) and mugginess at two diverse levels (moo and tall) to watch how these components influence plant development individually and in combination.
Therefore, the correct answer is (a) manipulating two or more independent variables.

Answer:
-7/2
Step-by-step explanation:
Slope equals rise (vertical or y axis) over run (horizontal or x axis). So you need to find two points on this line that cross directly where the grid lines cross. If you look closely, the line seems to cross directly at ( -6, 3 ) and again at ( -4, -4). So the rise values (y axis) are 3 and -4 which is a total of 7 units apart.
The run values are -6 and -4 which is a total of 2 units apart.
So your slope with be 7/2 but since it slopes downward to the right, it is a negative slope.
The answer would be negative 7/2

Iris's checking account pays simple interest at 4% per year. She has $180 in her account. Write a linear function to model the amount of money in her checking account at any time t.
A(t)=
The amount of money in Iris's checking account can be modeled by a linear function of the form:
y = mt + b
where y is the amount of money in the account, t is the time (measured in years), m is the rate of interest, and b is the initial amount in the account.
In this case, we have m = 0.04 (since the interest rate is 4% per year) and b = 180 (since that's the initial amount in the account). Therefore, the linear function that models the amount of money in Iris's checking account at any time t is:
y = 0.04t + 180
For example, if t = 5 (years), then the amount of money in Iris's checking account is 0.04 * 5 + 180 = 198 dollars.

the probability that someone prefers the lemon-flavored water over both competitors' brands is approximately 13.3%
we need to look at the overlap between the two groups that preferred the lemon-flavored water over competitor A and competitor B. According to the survey results, 35% of the 1000 people surveyed preferred the lemon-flavored water over competitor A, and 38% preferred it over competitor B. However, we also know that 47% did not prefer the lemon-flavored water over either competitor's brand.
To calculate the probability that someone prefers the lemon-flavored water over both competitors' brands, we need to use conditional probability. We can start by subtracting the percentage of people who did not prefer the lemon-flavored water over either competitor's brand from 100% to get the percentage of people who preferred at least one of the three drinks.
100% - 47% = 53%
Next, we can find the probability that someone prefers the lemon-flavored water over both competitors' brands by multiplying the percentages of people who preferred the lemon-flavored water over competitor A and competitor B.
35% × 38% = 13.3%
In conclusion, based on the survey results, we can say that there is a 13.3% probability that someone prefers the lemon-flavored water over both competitor A and competitor B.

10 | 4.00
11 | 4.00
12 | 4.00
Exponential smoothing is a forecasting method that uses past data to predict future values. The smoothing constant (α) determines how much weight is given to the most recent data. In this case, we are using a smoothing constant of 0, which means that all of the weight is given to the most recent data. This means that the forecasted registrations for all years will be the same as the starting forecast of 4.00.
Here is the formula for exponential smoothing:
```
Forecasted registrations = α * most recent data + (1 - α) * previous forecast
```
In this case, α = 0, so the formula becomes:
```
Forecasted registrations = most recent data
```
Since the most recent data is always 4.00, the forecasted registrations will always be 4.00.

On a chemistry quiz, there are 5 multiple choice questions with 4 choices each. What is the probability that you get a 100% if you strictly guess.
Answer:
0.097%
Step-by-step explanation:
Since this is a series of events probability question, in order to calculate the probability you need to first find the probability of getting each individual answer right and then multiplying those probabilities together. This will give you the probability of getting 100% on the entire test. Since the questions are multiple-choice with 4 choices and only 1 correct choice then the probability of getting one right is 1/4 or 25%. Now that we have that probability we simply need to multiply it 5 times for each individual question.
1/4 * 1/4 * 1/4 * 1/4 * 1/4 = 1/1024 or 0.0009765 or 0.097%

The postfix expression of "7+5-3*2(6*7)/4" is "7 5 + 3 2 * 6 7 * 2 * - 4 /". Evaluating the postfix expression gives the result of the expression. The prefix expression for the given infix expression is "/ - + 7 5 * 3 * 2 ( * 6 7 ) 4".
To convert the infix expression "7+5-3*2(6*7)/4" into postfix expression, we follow the rules of operator precedence and associativity. The postfix expression is obtained by placing operators after their operands.
The postfix expression for the given infix expression is:
"7 5 + 3 2 * 6 7 * 2 * - 4 /"
To evaluate the postfix expression, we use a stack data structure. We scan the postfix expression from left to right and perform the corresponding operations.
Starting with an empty stack, we encounter the operands "7" and "5". We push them onto the stack. Then we encounter the operator "+", so we pop the last two operands from the stack (5 and 7), perform the addition operation (7 + 5 = 12), and push the result back onto the stack.
We continue this process for the remaining operators and operands in the postfix expression. Finally, after evaluating the entire expression, the result left on the stack is the final answer.
To convert the infix expression into prefix expression, we follow similar rules but scan the expression from right to left. The prefix expression is obtained by placing operators before their operands.

For Tom's Pizza Restaurant where expenses for the restaurant include raw material for pizza, monthly rent and insurance, total 35 slices must be sold in a month to break even.
There is Tom has a Pizza Restaurant. Now, the Expenses for the restaurant include raw material for pizza = $7.02 per slices
Monthly rental = $ 121.00
Monthly insurance= $56.00
So, Monthly fixed expense = Rent + Insurance = 121+ 56 = $177
The sell rate of pizza = $12.02/slice.
We have to determine the number of slices restaurant sell in a month to break even.
Contribution margin per share = selling price per slice - variable cost per slice = 12.02 - 7.02 = $5.00
Number of slice to be sold to break even = Fixed cost divided by Contribution margin per slice = \(\frac{ 177}{5}\)
= 35.4
