6^{2} + b^{2} = 8^{2}

Answers

Answer 1

Answer:

-{2√7} or {2√7}

Step-by-step explanation:

1) Simplify the exponents 6^2 and 8^2 by multiplying 6*6=36 and 8*8=64.

2) Write an equation, 36+b^2=64

3) Subtract 36 from both sides, b^2=28

4) Apply a square root to both sides, √(b^2)=√(28)

5) Simplify the equation, b=-√(28) or b=√28

6) If you want, factor the square root by finding a factor that is a square number, -{√(4)*√7} or  {√(4)*√7};  -{2√7} or {2√7}

Answer 2

For a school project, Derek is investigating cell phone use in his hometown, Somerville. So far, he has found that the residents of Somerville used their cell phones for 11,609 minutes this year. Compared to last year, that is 30% more. For how many minutes did the residents of Somerville use their cell phones last year?

Answers

Answer:

Therefore, the residents of Somerville used their cell phones for approximately 8,930 minutes last year.

Step-by-step explanation:

To find out how many minutes the residents of Somerville used their cell phones last year, we can use the information given that this year's cell phone usage is 30% more than last year's.

Let's assume the cell phone usage last year was represented by the variable "x" (in minutes).

According to the information given, this year's cell phone usage is 30% more than last year's, so we can express this as:

x + 0.3x = 11609

Combining like terms, we have:

1.3x = 11609

To isolate the variable, we divide both sides of the equation by 1.3:

x = 11609 / 1.3

Simplifying the calculation, we find:

x ≈ 8930

Answer:

Therefore, the residents of Somerville used their cell phones for approximately 8,930 minutes last year.

Step-by-step explanation:

To find out how many minutes the residents of Somerville used their cell phones last year, we can use the information given that this year's cell phone usage is 30% more than last year's.

Let's assume the cell phone usage last year was represented by the variable "x" (in minutes).

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning

Answers

Answer: Please refer below mentioned explanation.

Step-by-step explanation:

Part A:

For Bay Side School: To find the median, we arrange the data in ascending order: 0, 0, 2, 3, 4, 5, 5, 5, 6, 6, 8, 8, 8 There are 13 data points, so the median is the 7th value, which is 5.

To find the mean, we sum up all the data points and divide by the number of data points: Mean = (0 + 0 + 2 + 3 + 4 + 5 + 5 + 5 + 6 + 6 + 8 + 8 + 8) / 13 = 66 / 13 ≈ 5.08

For Seaside School: To find the median, we arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 5, 5, 5, 6, 7, 7, 8, 8 There are 15 data points, so the median is the 8th value, which is 5.

To find the mean, we sum up all the data points and divide by the number of data points: Mean = (0 + 0 + 0 + 1 + 1 + 2 + 2 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8) / 15 = 57 / 15 ≈ 3.80

Part B:

For Bay Side School: Range = Maximum value - Minimum value = 8 - 0 = 8

For Seaside School: Range = Maximum value - Minimum value = 8 - 0 = 8

Part C:

Based on the measures of the center, Bay Side School has a higher mean and median compared to Seaside School. This suggests that, on average, Bay Side School tends to have larger class sizes than Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice. Additionally, both schools have the same range of 8, indicating that the spread of class sizes is similar between the two schools.

it’s y =x +32 it should be right

Answer:

y=x+32

Step-by-step explanation:

The initial value is the y-value when the x-value equals zero. In this case, the initial value is 32. In the equation y=mx+b, the initial value is the "b."

The slope is going to be the y-value divided by the x-value.

Count how many numbers to x-value goes up or down. In this case, it's positive 1. Count how many numbers the y-value goes up or down. In this case, it's also positive 1.

Now, divide the y-value by the x-value. It's 1/1, which equals 1.

So, that means that y=x+32 is the answer.

What is the interquartile range of this data set?

Answers

Answer:

IQR = 13

Step-by-step explanation:

First, lay out the set of data in a line.

20, 25, 30, 30, 31, 40, 41, 49

Next, we have to find the median, which is the middle of the set of data.

It is between 30 and 31, which is 30.5. Another way to find it is:

30 + 31 = 61

61 ÷ 2 = 30.5

Using that, we mark it between 30 and 31. Next, use the line of the mark, you use to separate the data into two.

20, 25, 30, 30 | 31, 40, 41, 49

Now, you find the median for each side. The left side will be the lower quartile, and the right side will be the upper quartile.

LQR = 25 + 30 = 27.5

UQR = 40 + 41 = 40.5

Now to find the IQR, you subtract the LQR from the UQR:

40.5 - 27.5 = 13

IQR = 13

Add all the numbers together to leave just the missing number (?)
7=(37+?)/6

To get rid of the 6 multiply it over to the other side
6x7=37+?
42=37+?

Now subtract the 37 to the other side to find the missing number (?)

What is the sum of the angle measures in this shape?

A) 180∘

B) 540∘

C) 720∘

D) 360∘

Answers

Answer:

B) 540

Step-by-step explanation:

To find the sum of interior angles of a polygon, we can use the following formula:

(n-2)·180, where n is the number of sides the polygon has.

In this case, this polygon has 5 sides, which makes it a pentagon.

(n-2)·180

substitute

(5-2)·180

simplify

3·180

=540

So, the total sum is 540°.

Hope this helps! :)

Answer: B) 540 degrees

Step-by-step explanation:

The formula for interior angles of a polygon is 180(n-2). N is the number of sides.

Plug the given values into the equation:

180(5-2)=180*3=540

The sum of exterior angles of any polygon is 360 degrees. This problem didn't specify, so I would assume it's talking about interior angles, so the answer would be 540 degrees.

Answers

Answer:

Step-by-step explanation:

The Allstars team has the higher mean and median compared to Champs team. Therefore, the Allstars has the tallest players.

Using Mean and Median to Decide the Tallest Team

By using mean and median, we can know which team typically has the tallest players

For the Allstars:

Mean: The mean height of the Allstars team is obtained by summing up all the heights and dividing by the total number of players:

Mean = (73 + 62 + 60 + 63 + 72 + 65 + 69 + 68 + 71 + 66 + 70 + 67 + 60 + 70 + 71) / 15 ≈ 67.1 inches

Median: The median height of the Allstars team is the middle value when the heights are arranged in ascending order:

Arranging the heights in ascending order: 60, 60, 62, 63, 65, 66, 67, 68, 69, 70, 70, 71, 71, 72, 73

Median = 68 inches

For the Champs:

Mean: The mean height of the Champs team is obtained by summing up all the heights and dividing by the total number of players:

Mean = (62 + 69 + 65 + 68 + 60 + 70 + 70 + 58 + 67 + 66 + 75 + 70 + 69 + 67 + 60) / 15 ≈ 66.4 inches

Median: The median height of the Champs team is the middle value when the heights are arranged in ascending order:

Arranging the heights in ascending order: 58, 60, 60, 62, 65, 66, 67, 67, 68, 69, 69, 70, 70, 70, 75

Median = 67 inches

The Allstars team typically has the tallest players. The mean height of the Allstars team is about 67.1 inches, while the mean height of the Champs team is about 66.4 inches. Additionally, the median height of the Allstars team is about 68 inches, while the median height of the Champs team is about 67 inches. Both the mean and median heights of the Allstars team are higher, indicating that, on average, the Allstars team has taller players compared to the Champs team.

What is an equation for the linear function whose graph contains the points (−1,−2) and a slope of 3?

Enter your answers in the boxes.

y+ ? = ? (x+1)

Answers

Answer:

The point-slope form of the equation of a line is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. In this case, we have a point (-1,-2) and a slope of 3. Substituting these values into the equation, we get:

y - (-2) = 3(x - (-1))

Simplifying this equation, we get:

y + 2 = 3(x + 1)

So, the equation for the linear function whose graph contains the point (-1,-2) and has a slope of 3 is y + 2 = 3(x + 1).

Answer:
Y + 2 = 3( X + 1 )


Explanation:
The equation is
Y - Y1 = M(X - X1)

Y1 is the y value:
The y value for the point (-1,-2) is -2 so we can plug that in

Y - (-2) = M( X - X1 )
If you subtract a negative you are adding so:
Y + 2 = M( X - X1 )

X1 stands for X
The X value for (-1,-2) is -1 same as the last one it will be positive because if you subtract a negative you are adding it:
Y + 2 = M( X + 1 )

Finally we plug in M
M is the slope and slope = 3 so plug 3 in
Y + 2 = 3( X + 1 )

Answer is Y + 2 = 3( X + 1 )

The fileFlightDelays.cv contains information on allcommercial flights departing theWashington, DC area and arriving at NewYork during January 2004. For each flight,there is information on the departure andarrival airports, the distance of the route,the scheduled time and date of the flight,and so on. The variable that we are trying topredict is whether or not a flight is delayed.A delay is defined as an arrival that is atleast 15 minutes later than scheduled.Data Preprocessing. Transform variable dayof week (DAY WEEK) info a categoricalvariable. Bin the scheduled departure timeinto eight bins (in R use function cut)). Usethese and all other columns as predictors(excluding DAY_OF_MONTH). Partition thedata into training and validation sets.a. Fit a classification tree to the flight delayvariable using all the relevant predictors. Donot include DEP TIME (actual departuretime) in the model because it is unknown atthe time of prediction (unless we aregenerating our predictions of delays afterthe plane takes off, which is unlikely). Use apruned tree with maximum of 8 levels,setting cp = 0.001. Express the resultingtree as a set of rules.b. If you needed to fly between DCA andEWR on a Monday at 7:00 AM, would you beable to use this tree? What otherinformation would you need? Is it availablein practice? What information is redundant?C. Fit the same tree as in (a), this timeexcluding the Weather predictor. Displayboth the pruned and unpruned tree. You willfind that the pruned tree contains a singleterminal node.i. How is the pruned tree used forclassification? (What is the rule forclassifying?)il. To what is this rule equivalent?ill. Examine the unpruned tree. What are thetop three predictors according to this tree?iv. Why, technically, does the pruned treeresult in a single node?v. What is the disadvantage of using the toplevels of the unpruned tree as opposed tothe pruned tree?vi. Compare this general result to that fromlogistic regression in the example in what happens to the partial pressure of carbon dioxide in the blood during rapid breathing? Refer to the Johnson Filtration problem introduced in this section. Suppose that in addition to information on the number of months since the machine was serviced and whether a mechanical or an electrical repair was necessary, the managers obtained a list showing which repairperson performed the service. The revised data follow.Repair Time in HoursMonths Since Last ServiceType of RepairRepairperson2.92ElectricalDave Newton36MechanicalDave Newton4.88ElectricalBob Jones1.83MechanicalDave Newton2.92ElectricalDave Newton4.97ElectricalBob Jones4.29MechanicalBob Jones4.88MechanicalBob Jones4.44ElectricalBob Jones4.56ElectricalDave Newtona) Ignore for now the months since the last maintenance service (x1) and the repairperson who performed the service. Develop the estimated simple linear regression equation to predict the repair time (y) given the type of repair (x2). Recall that x2 = 0 if the type of repair is mechanical and 1 if the type of repair is electrical.b) Does the equation that you developed in part (a) provide a good fit for the observed data? Explain.c) Ignore for now the months since the last maintenance service and the type of repair associated with the machine. Develop the estimated simple linear regression equation to predict the repair time given the repairperson who performed the service. Let x3 = 0 if Bob Jones performed the service and x3 = 1 if Dave Newton performed the service.d) Does the equation that you developed in part (c) provide a good fit for the observed data? Explain.e) Develop the estimated regression equation to predict the repair time given the number of months since the last maintenance service, the type of repair, and the repairperson who performed the service.f) At the .05 level of significance, test whether the estimated regression equation developed in part (e) represents a significant relationship between the independent variables and the dependent variable.g) Is the addition of the independent variable x3, the repairperson who performed the service, statistically significant? Use = .05. What explanation can you give for the results observed? Please do the question using the integer values provided. Pleaseshow all work and steps clearly thank you!5.
