(2 points 8. Triangle ABC is shown on the graph below! IL 6 1 c. Triangle ABC is translated 1 unit night and 2 units down. What are the coordinates of the translated triangle? d. Use arrow Rotation to write a rule for this translation,
Answer:
see explanation
Step-by-step explanation:
(c)
1 unit right means add 1 to the x- coordinate
2 units down means subtract 2 from the y- coordinate.
A (1, 3 ) → A' (1 + 1, 3 - 2 ) → A' (2, 1 )
B (4, 5 ) → B' (4 + 1, 5 - 2 ) → B' (5, 3 )
C (3, 1 ) → C' (3 + 1, 1 - 2 ) → C' (4, - 1 )
(d)
the translation rule is
(x, y ) → (x + 1, y - 2 )

the ages of all the patients in the isolation ward of the hospital are 38, 26, 13, 41, and 22. what is the population variance?multiple choice106.8240.391.442.4
106.8 is the population variance.
To calculate the population variance, we use the formula:
\(s^{2}\) = Σ [\((xi-u)^{2}\)] / N,
where xi is the ith observation, u is the population mean, and N is the population size.
First, we need to calculate the population mean:
u = (38 + 26 + 13 + 41 + 22) / 5 = 28.
Next, we calculate the sum of squares:
Σ [\((xi-u)^{2}\)] = \((38-28)^{2}+ (26-28)^{2}+(13-28)^{2}+(41-28)^{2}+(22-28)^{2}\)
= 100 + 4 + 225 + 169 + 36
= 534.
Finally, we divide by the population size:
\(s^{2}\) = Σ [\((xi-u)^{2}\)] / N = 534 / 5 = 106.8.
Therefore, the population variance is 106.8.
The closest choice to this answer is 106.8, which is the first option. So the answer is 106.8.

City received 3/4 inch of rain on July 31  This represents 3/10 of the total amount of rain this to received in July the equation 3/10r =3/4 can be used to find the amount of rain r in inches  The city received in July how much rain did the city receive in July ?
The amount of rain the city received in July is r = 2.5 inches
Given data ,
City received 3/4 inch of rain on July 31
Now , it represents 3/10 of the total amount of rain this to received in July
So , the equation is represented as A
Now , the value of A is
( 3/10 )r = 3/4
Multiply by 10 on both sides , we get
3r = 30/4
Divide by 3 on both sides , we get
r = 30/12
r = 2.5 inches

Which of the following systems is dependent?
x − y = 2 and x y = −2
x − y = 2 and −2x 2y = −4
x − y = 2 and 3x − 3y = 2
x − y = 2 and −x − y = −2
The system of equation x − y = 2 and −2x+2y = −4 is dependent becasue the they have same coefficient of x and y option second is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
As we know, if the two linear equations have the same coefficient of x and y they are dependent or if the graph of two linear equations is the same then the equations are dependent.
From the given options, we can see the system of equations:
x − y = 2 and −2x + 2y = −4 are the same equation.
Take the equation −2x + 2y = −4 and divide by -2 on both sides, we get:
x - y = 2
This is the same equation as x − y = 2
Thus, the system of equation x − y = 2 and −2x+2y = −4 is dependent becasue the they have same coefficient of x and y option second is correct.

Marissa selects a card in a hat, notes which color it is, returns the card to the hat, and repeats. The results of 70 trials are 12 red cards, 38 green cards, and 20 purple cards. What are the experimental probabilities of selecting each color, based on these results?
Probability of selecting a red card=
Probability of selecting a green card=
Probability of selecting a purple card=
Answer:
Red=17.1%
Green=54.3%
Purple=28.6%
All of these answers are rounded.
Step-by-step explanation:
To solve for all, all you have to do is divide the number of trials of the specific color by the total number of trials. To get a percentage you then multiply by 100%.
Red:
12/70=0.171*100%=17.1%
Green:
38/70=0.543*100%=54.3%
Purple:
20/70=0.286*100%=28.6%
To check if you've rounded correctly, add all your values and they should add up to 100 exactly. If it is slightly over or below you may need to go back and check for a rounding error.

if you wanted to perform a hypothesis test that the mean service time for vendor 1 (µ1) greater than vendor 2 (µ2), which one of the following would be an appropriate null and alternative hypothesis?
This hypothesis test is a one-tailed test, which is the response to the supplied question based on the hypothesis test.
What is Null hypothesis?A statement that there is no significant difference between two or more populations or that there is no correlation between two variables is known as the null hypothesis in statistical hypothesis testing. "H0" is a common notation for it.
Until contrary evidence is presented, the null hypothesis—which is typically the default position—is taken to be true. "H1" stands for the alternative hypothesis, which is the null hypothesis's opposite and is the hypothesis that is put to the test.
The following will serve as an appropriate null and alternate hypothesis when determining if vendor 1's mean service time (µ1) is longer than vendor 2's (µ2):
It is true that vendor 1's mean service time is shorter than or equal to vendor 2's mean service time (µ1 ≤ µ2).
As an alternative, vendor 1's mean service time is longer than vendor 2's mean service time (µ1 > µ2).
We are solely interested in the probability that the mean service time for vendor 1 is longer than that of vendor 2 in our one-tailed hypothesis test.

The steady state flow in a five-spot waterflooding (i.e. injecting water into the reservoir to displace oil towards production well(s)) is given by the following equation.
q=7.081*10-3 kh/Bμ Pw-Ppw /[In(d/rw)-0.619
What is the dimensionless productivity index for this well? In this equation Rix is the injection well pressure and Ppw is the production well pressure and d is the distance between the injection and production well. (Please see the five spot figure in your notes.) In order to be able to increase the injection rate q. how would you change the three controllable variables piw, ppw and d? Discuss with your friends and other experts if there are any restrictions on varying these variables freely.
To increase the injection rate q, we can increase the injection well pressure (piw), decrease the production well pressure (ppw), or decrease the distance between the injection and production well (d) any changes in these variables should be carefully evaluated and monitored to avoid any adverse effects on the reservoir performance.
How injection rate varies with different scenario?
The dimensionless productivity index for the well in the given equation can be calculated by dividing the flow rate (q) by the pressure difference (Pw-Ppw) and the distance between the wells (d).
The dimensionless productivity index = q / (Pw-Ppw)d
In order to increase the injection rate q, we can change the three controllable variables piw, ppw and d.
To increase the injection rate q, we can increase the injection well pressure (piw), decrease the production well pressure (ppw), or decrease the distance between the injection and production well (d).
However, there may be some restrictions on varying these variables freely. For example, increasing the injection well pressure beyond a certain limit may cause formation damage or fracture the reservoir rock. Similarly, decreasing the production well pressure too much may result in water coning or gas breakthrough.
Moreover, decreasing the distance between the wells may not be feasible due to the geological or physical constraints of the reservoir.
Therefore, any changes in these variables should be carefully evaluated and monitored to avoid any adverse effects on the reservoir performance.
