Answer:

y = 2x+4

Step-by-step explanation:

We need to find the slope

m = (y2-y1)/(x2-x1)

 = (8--6)/(2--5)

  = (8+6)/(2+5)

  = 14/7

  =2

Now we can use the point slope form of a line

y-y1 = m(x-x1)

y--6 = 2 (x--5)

y+6 = 2(x+5)

If we want it in slope intercept form

Distribute the 2

y+6 = 2x+10

Now subtract the 6 from both side

y+6-6=2x+10-6

y = 2x+4

Answer:

y = 2x - 1

Step-by-step explanation:

The line passes through points A(1, 1) and B(2, 3).

The slope-intercept form of the equation of a line is

y = mx + b,

where m = slope, and b = y-intercept.

We see from the graph that the y-intercept is -1, so b = -1, and we have

y = mx - 1

Going from point A to point B, we go up two units and right 1 unit. Slope = m = difference in y over difference in x, so

m = 2/1 = 2

The equation is

y = 2x - 1

Answer: 2x + -1

Step-by-step explanation: In this problem, we're asked to write the equation of the given line in slope-intercept form.

Slope-intercept form is the same thing as y = mx + b form where m represents the slope of the line and b represents the y-intercept. So our first step is to find the slope and the y-intercept of the given line.

To find the slope, we use the ratio rise over run between any two points on the line. To get from point A to point B along this line, we rise 2 units and run 1 unit. So our slope or rise over run is 2/1 or just 2.

Next, to find the y-intercept, it's important  to understand that the y-intercept is the point where the line crosses the y-axis. Notice that this line crosses the y-axis at the point (0,-1) which means that the y-intercept is -1.

Therefore, m = 1/2 and b = -1 and we substitute these values into our formula for m and b to get y = 2x + -1.

So the equation of the given line in slope-intercept form is y = 2x + -1.

First multiply C by F by multiplying each row in C by each column in F:

12 * -2 + 0*0 + 1.5*2   12*0 + 0*8 + 1.5*1

1*-2 -6*0 +7.2       1*0-6*8 +7*1

to get a matrix of:

-21   1.5

12   -41

Now subtract that matrix from B:

2- -21 = 2+21 = 23

8 - 1.5 = 6.5

0.6 - 12 = -11.4

3 - -41 = 3+41 = 44

So you have:

23   6.5

-11.4   44

Which makes C the correct answer.

Answer:

We have to find the equation of least squares regression line in order to find the number of ice cream cones that the shopkeeper to sell if the temperature is 106 degrees. We can use excel regression data analysis tool to find the equation of the regression line. The excel output is attached here.

The equation of the least squares regression line is:

[tex]\hat{y}=46.587+5.080x[/tex]

Now, if the temperature is 106 degrees, then the number of cones expected to be sold is given below:

[tex]\hat{y}=46.587+5.080 \times 106[/tex]

         [tex]=585.1 \approx 585[/tex]

Therefore, the number of ice cream cones that the shopkeeper would expect to sell if the temperature is 106 degrees is 585.

Given Equations :

✿  5x + 3y = -6 -------------- [1]

✿  3x - 2y = 4 -------------- [2]

Multiplying Equation [1] with 2, We get :

⇒ 10x + 6y = -12 ----------- [3]

Multiplying Equation [2] with 3, We get :

⇒ 9x - 6y = 12 ---------- [4]

Adding Both Equations [3] and [4], We get :

⇒ (10x + 6y) + (9x - 6y) = -12 + 12

⇒ 19x = 0

⇒ x = 0

Substituting x = 0 in Equation [1], We get :

⇒ 5(0) + 3y = -6

⇒ 3y = -6

⇒ y = -2

⇒ (x , y) = (0 , -2)

Option (a) is the Answer

Answer: A (0, -2)

Step-by-step explanation:

5x + 3y = -6   →   2(5x + 3y = -6)   →   10x + 6y = -12

3x  - 2y =  4   →   3(3x  - 2y =  4)   →   9x  - 6y = 12

                                                          19x           =  0

                                                              x          =  0

Now, input "x = 0" into one of the equations and solve for y:

5x + 3y = -6

5(0) + 3y = -6

         3y = -6

           y = -2

Answer:

38.4

Step-by-step explanation:

48*20%=9.6 48-9.6=38.4

The question requires us to use the exponential distribution to calculate the probability of waiting more than 15 minutes between two successive calls given a Poisson process with β parameter 1/6. We achieve this by using the cumulative distribution function. The probability is approximately 96.4%.

This question is essentially asking us to use the exponential distribution to calculate the probability of waiting for more than 15 minutes (which is 0.25 hour because we are dealing with hours as units of time) between two successive calls when the parameter β =1/6 is given. The exponential distribution is used to model the time between events in a Poisson process, and the probability density function is given by f(x) = βe^(-βx) for x ≥ 0.

The cumulative distribution function is F(x) = 1 - e^(-βx), so to compute the probability of waiting time that is more than 0.25 hour, we subtract the cumulative distribution function from 1.

So, P(X > 0.25) = 1 - P(X ≤ 0.25) = 1 - [1 - e^(-β * 0.25)] = e^(-β * 0.25) = e^(-(1/6) * 0.25) ≈ 0.964, or 96.4% as the answer.

Answer:

351 adults and 275 students

Step-by-step explanation:

We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 626 tickets were purchased, then s+a=626.

We also know that 74 fewer student tickets then adult tickets. So s+76=a, the number of student tickets plus 76 will be the number of adult tickets.

We will solve by substituting one equation into the other. We substitute a=76+s into s+a=626. Simplify and isolate the variable a.

s+a=626

s+76+s=626

2s+76=626

2s+76-76=626-76

2s=550

s=275

This means that 275 students attended and 351 adults attended since 275+351=626.

By setting up a system of equations and solving for the number of adult tickets, we are able to determine that 350 adult tickets were sold for the school play.

To find out how many adult tickets were sold, we can set up an equation to model the situation. Let A be the number of adult tickets and S be the number of student tickets. We are given that a total of 626 tickets were sold, which can be described by the equation A + S = 626. We are also told that there were 74 fewer student tickets sold than adult tickets, described by the equation S = A - 74.

To solve for A, we can substitute (A - 74) for S in the first equation, giving us A + (A - 74) = 626. Simplifying this, we get 2A - 74 = 626. Adding 74 to both sides, we get 2A = 700. Finally, dividing both sides by 2, we find A = 350.

Therefore, 350 adult tickets were sold.

Therefore, the interpretation of [tex]R^{2}=12.7\%[/tex] is 12.7% of variation in gpa response variable is explained by the jobs explanatory variable in the given linear regression model.

the R-squared statistic of 12.7% suggests that there is a weak linear relationship between the number of hours worked and GPA among the sampled students, and the majority of the variation in GPA is due to factors beyond the number of hours worked.

The R-squared statistic, often denoted as R², measures the goodness of fit of a linear regression model. In this context, where the R-squared statistic is 12.7%, it means that approximately 12.7% of the variability in GPA can be explained by the linear relationship with the number of hours per week students work.

More specifically:

- 12.7% of the variation in GPAs among the students in the sample can be accounted for by the linear regression model with the number of hours worked as the predictor variable.

- The remaining 87.3% of the variability in GPAs is not explained by this model and is attributed to other factors or sources of variation that are not included in the model.

In summary, the R-squared statistic of 12.7% suggests that there is a weak linear relationship between the number of hours worked and GPA among the sampled students, and the majority of the variation in GPA is due to factors beyond the number of hours worked.

Answer:

Step-by-step explanation:

The edge length (s) of an equilateral triangle is (2/3)√3 times the height. This means the edge length of your triangle is ...

... s = (2/3)√3 × 12√2 = 8√6

The perimeter is 3 times the side length:

... p = 3s = 3×8√6 = 24√6 . . . cm

The area is half the product of edge length and height:

... a = (1/2)sh = (1/2)(8√6)(12√2) = 48√12 = 96√3 . . . cm²

The perimeter of the equilateral triangle is 24√6 cm, and its area is 96√3 cm².

To find the perimeter and area of an equilateral triangle with a given height, we can follow these steps:

First, let's denote the side length of the equilateral triangle as a. In an equilateral triangle, the height (h) can be found using the formula:

h = (a√3)/2

We know the height is 12√2 cm. Therefore,12√2 = (a√3)/2

To find the side length a, we can rearrange the equation: a = 2 * 12√2 / √3

Simplify the expression: a = 24√2 / √3

Multiplying numerator and denominator by √3 to rationalize the denominator: a = 24√6 / 3

a = 8√6

Now, the perimeter (P) of the equilateral triangle is given by: P = 3a

Substitute the value of a: P = 3 * 8√6

P = 24√6 cm

Next, we calculate the area (A) using the formula: A = (base * height) / 2

In an equilateral triangle, the base is equal to the side length a, and the height is given as 12√2 cm:

A = (8√6 * 12√2) / 2

Multiplying the bases and simplifying: A = (96√12) / 2

Since √12 can be simplified to 2√3: A = (96 * 2√3) / 2

A = 96√3 cm²

The perimeter of the equilateral triangle is 24√6 cm, and its area is 96√3 cm².

To find out how much longer we have before we finish the movie, subtract the time already watched from the total duration of the movie.

Explanation:

To find out how much longer we have before we finish the movie, we need to subtract the time we have already watched from the total duration of the movie.

Given that the movie is 28 minutes and 58 seconds long, and we have already watched 13 minutes and 44 seconds, we subtract the time already watched from the total duration:

28 minutes 58 seconds - 13 minutes 44 seconds = 15 minutes 14 seconds.

Therefore, we have 15 minutes and 14 seconds left before we finish the movie.

Answer for question number 7 is 58.4

Step-by-step explanation:

Nicolas sells 5.125 pounds of shrimp per hour.

Therefore, he can sell 46.125 pounds of shrimp in 9 hours.

To determine how many pounds of shrimp Nicolas sold in one hour, we need to divide the total pounds of shrimp by the total number of hours.

Nicolas sold 20 1/2 pounds of shrimp in 4 hours.

Therefore, we divide 20.5 (which is the decimal equivalent of 20 1/2) by 4 to find the rate per hour:

20.5 ÷ 4 = 5.125

Nicolas sold 5.125 pounds of shrimp per hour.

To find out how many pounds he can sell in 9 hours, we multiply the rate per hour by 9:

5.125 × 9 = 46.125

Nicolas can sell 46.125 pounds of shrimp in 9 hours.

Answer: (1,3)

All you're doing is looking for where the two lines cross, or the point of intersection. What you can do is draw a vertical line through this intersection point to see that the vertical line lands on x = 1 on the x axis. At the same time, draw a horizontal line to the y axis and it will get to y = 3.

So together x = 1 and y = 3 pair up to get (x,y) = (1,3)
