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).
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 )

Key: 2 | 1 | 0 means 12 for Bay Side and 10 for Seaside
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.

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.
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

we only want to find the probabilty for pink
so we are gonna put 12 over 38 ( which looks like this : 12/38)
we want to simplify it and the simplified verson of 12/38 is 6/19
that could be your total number if they want it as a fraction if they want it as a decimal put 6/19 in your calcalator and that will come up as 0.315789473684 then press times 100 which will put it in the correct spot with will come up as 31.5789473684 since there is a 7 next to the 5

Step-by-step explanation:
Let me break it down into simple terms:
The question states, "cube with this net".
A cube has all 6 surfaces that are equal. The surface area is the area of each side added up.
In this case, since this net would form a cube, we can use the formula:
6·area of 1 square to get the surface area of the entire net.
We know that to find the area of a shape, it's simply length times width:
2.5x2.5
=6.25
Now, substitute that into the original equation (6·area of 1 square)

The Champs, with a median of about 67 inches
Answers
Answer:
45
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 TeamBy 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.

A manufacturer inspects 50 computer monitors and finds that 45 have no defects. What is the experimental probability that a monitor chosen at random has no defects?
Answers
Answer:
The experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials or observations.
In this case, the event is choosing a monitor with no defects, and the number of times the event occurs is 45. The total number of monitors is 50.
So, the experimental probability of choosing a monitor with no defects is:
45/50 = 0.9
Therefore, the experimental probability that a monitor chosen at random has no defects is 0.9 or 90%.

Because 8+8+8+6+7+5=42
Then divide that by 6 to get the mean - so 42/6=7 so that’s the correct mean
Explanation:
Mean = average

Mean=7+8+6+8+?+8/6
The mean is given: 7
So plug it in:
7=(7+8+6+8+?+8)/6
Factor to solve:
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 (?)
42-37=?

Jeff spends $2.52 per gallon of gas and buys 14 gallons. Anna spends $2.16 per gallon of gas and buys 15 gallons.
How much more does Jeff spend than Anna on gas?
Answers
Step-by-step explanation:
Jeff spends $2.52 per gallon and buys 14 gallons, so his total expenditure is:
Total spent by Jeff = $2.52/gallon * 14 gallons = $35.28
Anna spends $2.16 per gallon and buys 15 gallons, so her total expenditure is:
Total spent by Anna = $2.16/gallon * 15 gallons = $32.40
To find the difference in their expenditures, we subtract Anna's total from Jeff's total:
Difference = Total spent by Jeff - Total spent by Anna
Difference = $35.28 - $32.40 = $2.88
Therefore, Jeff spends $2.88 more than Anna on gas.
Jeff's total expense = $2.52/gallon * 14 gallons = $35.28
Anna's total expense = $2.16/gallon * 15 gallons = $32.40
The difference in their expenses is $35.28 - $32.40 = $2.88.
Therefore, Jeff spends $2.88 more than Anna on gas.
What is the interquartile range of this data set?

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
