Find the mean and median of the data set.
There are 50, 52, 51, 48, 53, and 52 students in a school's 6 Algebra 1 classes.
The mean is-
The median is-
Answer:
Mean: 50.8 or 51 (rounded)
Median: 51.5 or 52 (rounded)
Step-by-step explanation:
To find the mean I added all the numbers then divides my sum but the number of numbers.
To find the median I listed the numbers from least to greatest.There are two middle numbers so I added the two numbers and divided the same by 2.

Enter your answer in the answer box and then click Check Answer
Answer:
i. [tex]x^{2}[/tex] + 26x + 144 - 299 = 0
ii. x = 5
Step-by-step explanation:
The area of the figure = 299 cm²
The figure has a shape of a rectangle, so that;
Area of rectangle = length x width
length of the figure = 18 + x
width of the figure = 8 + x
Area of the figure = (18 + x) x (8 + x)
299 = (18 + x) x (8 + x)
299 = [tex]x^{2}[/tex] + 26x + 144
[tex]x^{2}[/tex] + 26x + 144 - 299 = 0
[tex]x^{2}[/tex] + 26x - 155 = 0
applying the trigonometric formula;
x = (-b ± [tex]\sqrt{b^{2} - 4ac}[/tex]) ÷ 2a
= (-26 ± [tex]\sqrt{(26)^{2} - 4(1*-155)}[/tex]) ÷ 2
= (-26 ± [tex]\sqrt{676 +620}[/tex]) ÷ 2
= (-26 ± [tex]\sqrt{1296}[/tex]) ÷ 2
= (-26 ± 36) ÷ 2
x = (-26 + 36) ÷ 2 OR x = (-26 -36) ÷ 2
= 10 ÷ 2 OR -62 ÷ 2
= 5 OR -31
Thus, x = 5

the graph shows the depth,y, in meters, if a shark from the surface of an ocean for a certain amount of time, x, in minutes:
part a: describe how you can use similar triangles to explain why the slope of the graph between points a and b is the same as the slope of the graph between points a and c?
part b: what are the initial value and slope of the graph, and what do they represent?
Answer: Look at the step-by-step
Step-by-step explanation:
Part A: We can use two right triangles that represent rise over run to explain the slope of points A and B which has the same slope of points A and C. Since there will be two right triangles, they are considered similar triangles.
AB: 154 - 110= 44
44/2= 22
AC: 154 - 66 = 88
88/2=44
This means that the slope of the two sets of points is 44, and it represents the rate of change of the shark travelling away from the ocean’s surface every minute.
Part B: The initial value is 66 (m), and it represents the initial position of the shark at 0 minutes.
The equation of line is y = where y is the distance from ocean surface and x is the time taken in minutes , where the slope is m = 44 m/min
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the number of minutes be x
Let the distance from ocean surface be y
Let the first point be P ( 0 , 66 )
where P is the initial point of the graph
Let the second point be Q ( 2 , 110 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 110 - 66 ) / ( 2 - 1 )
Slope m = 44
And , the equation of line is
y - 66 = 44 ( x - 0 )
Adding 66 on both sides , we get
y = 44x + 66
Hence , the equation of line is y = 44x + 66

I don’t understand how to solve this graph.
(Y=MX+B)
Answer:
The equation of line shown in the graph is [tex]\mathbf{y=-\frac{1}{2}x -1}[/tex]
Step-by-step explanation:
We need to find equation of the line shown in graph.
The equation of line will be in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding y-intercept
Looking at the graph, we can find y-intercept when x =0, the value of y is known as y-intercept.
So, when x =0, y=-1
So, y-intercept is -1
Finding Slope
Now, for finding slope, consider 2 points on graph
(0,-1) and (-2,0)
Slope can be found using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=0, y_1=-1, x_2=-2, y_2=0[/tex]
Putting values and finding slope:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{0-(-1)}{-2-0} \\Slope=\frac{0+1}{-2-0} \\Slope=\frac{1}{-2} \\Slope=-\frac{1}{2}[/tex]
So, slope is [tex]m=-\frac{1}{2}[/tex]
Equation of line
Now, equation of line having slope [tex]m=-\frac{1}{2}[/tex] and y-intercept b = -1 is
[tex]y=mx+b\\y=-\frac{1}{2}x -1[/tex]
So, equation of line shown in the graph is [tex]\mathbf{y=-\frac{1}{2}x -1}[/tex]

Answer:
We conclude that segment QR is the shortest.
Hence, option B is true.
Step-by-step explanation:
First, we need to determine the missing angle m∠R
Given the triangle Δ∠PQR
m∠P = 48°
m∠Q = 83°
m∠R = ?
We know the sum of angles of a triangle is 180°.
m∠P+m∠Q+m∠R = 180°
48°+83°+m∠R=180°
m∠R = 180° - 48° - 83°
m∠R = 49°
Thus, the value of m∠R = 49°
We know that the longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.
Here,
m∠P = 48° is the shortest angle.
As the side QR segment is opposite the smallest angle i.e. m∠P = 48°
Therefore, we conclude that segment QR is the shortest.
Hence, option B is true.

Which of the following represents the y-intercept of the function y = log (x + 100) - 4 ? *
a. -1
b. -2
c. -3
d. -4
Answer:
b
Step-by-step explanation:
To find the y- intercept, let x = 0 in the equation and solve for y, that is
y = [tex]log_{10}[/tex](0 + 100) - 4
= [tex]log_{10}[/tex] 100 - 4
= 2 - 4
= - 2 ← y- intercept → b
The y-intercept of the function y = log (x + 100) - 4 is -2
What is y-intercept?The y-intercept is the point where the line intersects the y-axis.
Given a function, y = log (x + 100) - 4
Solving for the y- intercept,
Let x = 0 in the equation and solve for y, that is
y = log(0 + 100) - 4
= log100 - 4
= 2 - 4
= -2
Hence, The y-intercept of the function y = log (x + 100) - 4 is -2

How do you figure these out?? I need major help!!
Answer:
The value of x = 5
Step-by-step explanation:
It is clear that a traversal line is passing through two parallel lines.
It is also clear that:
The angle (35+2x)° and 60° are on the outside of the parallel lines and on the opposite side of the traversal. Therefore, (35+2x)° and 60° are Alternate Exterior Angles.
Please remember that Alternate Exterior Angles are congruent, so
35 + 5x = 60°
subtract 35 from both sides
35 + 5x - 35 = 60° - 35
5x = 25
divide both sides by 5
5x/5 = 25/5
x = 5
Therefore, the value of x = 5

Tara is graphing the equation 4x + 2y = 10. Which of these shows the correct equation in slope-intercept form, slope, and y-intercept?
Question 2 options:
y = –2x + 5
slope = –2
y-intercept = 5
y = 2x + 4
slope = 2
y-intercept = 4
y = –4x + 5
slope = –4
y-intercept = 5
y = 4x + 5
slope = 4
y-intercept = 5
Answer: y = -2x + 5
Step-by-step explanation:
y = -2x + 5
slope = -2
Slope intercept form of equation of line is given by y = mx + c
where m is the slope of line
c is the y intercept i.e point where given line intersect y axis.
________________________________________________
given equation 4x + 2y = 10
we have to re-write this equation in form y = mx + c
4x + 2y = 10
subtraction 4x from LHS and RHS
4x + 2y - 4x= 10 - 4x
2y = 10- 4x
we have to eliminate 2 from y for that we
divide LHS and RHS by 2 we
2y /2 = 10/2- 4x/2
y = 5 - 2x
rearranging it in y = mx+c form
y = -2x + 5
thus, m = -2 , c = 5
Answer:
y=-2x+5, slope= -2, y-intercept= 5 (so, first option)
Step-by-step explanation:
y=mx+b. m is the slope, and b is the y-intercept. to get the equation to the slope intercept form, you get y by itself- subtract 4x from both sides and then divide by 2 on both sides.

4 = 4x
Divide 4 from both sides
4/4 = 4x/4
1 = x
x = 1
