Now, they ask you an integer that represents a change per hour, and they say you that assume a constant change... then we complement the table with different values per hour until arrive at midnight..

100 students took an exam, the maximum score was 90. From the graph, 1.what was the median score?2.Also, find the lower quartile score. in reference to the first question. 3. what is the inter-quartile score range score?
0. From the given graph, the cumulative frequency value indicates the number of students, we have 100 total number of students .
• so,Median is half of the students = 100/2 = 50
the value of test score that corresponds with 50 = 55 test score
• This means that the median , 50 students scored 55 % in the exa,m.
2. Finding the lower quartile Q1 :
since we have 100 students , 100/4 = 25, so Q1 = 25
the value that corresponds with cumulative frequency of 25 = 45
• This means that 25 students scores 45 %
3. Finding the Interquartile range :
IQR = Upper Quartile -Lower Quartile
Upper quartile = Q3 = 75 students : 60 %
and lower quartile = 45%
So,
IQR = 60-45
= 15
• This means that 15 students got 35 %

The linear equation parallel to y = 3x - 2 that passes through the point (4, 6) is:
y = 3*x - 6
How to find the equation of the parallel line?Here we want to find a linear equation parallel to:
y = 3x - 2
Now, a general linear equation is:
y = m*x + b
Where m is the slope and b is the y-intercept.
Remember that two lines are parallel if and only if the lines have the same slope and different y-intercept.
So our linear equation will be something like:
y = 3*x + c
Now we also want our line to pass through the point (4, 6), then we can replace these values:
6 = 3*4 + c
6 = 12 + c
6 - 12 = c
-6 = c
So the linear equation is:
y = 3*x - 6

3 sisters age combined are 57. Jenny is 6 years
older then Lynn. Kim is 5 less then twice the age of
Lynn age. What are the sisters ages.
Jenny's age is 20 years, Lynn is 14 years and Kim is 23 years.
Let's take Jenny as J, Kim as K and, Lynn as L.
From the given statement we get the equation.
As the sum of the age of the three sisters is 57. So we have an equation,
J + K + L = 57 ........(i)
Jenny is 6 years older than Lynn. So the next equation is,
J = 6 + L .......(ii)
Kim is 5 years less than twice her age Lynn. So the equation is,
K = 2L -5 .........(iii)
Putting equations (ii) and (iii) in equation (i)
6 +L + 2L - 5 + L = 57
4L = 56
L = 14
Put the value of L in equations (ii) and (iii)
J = 6 + 14
= 20
K = 2(14) -5
= 28 - 5
= 23
Therefore the age of Jenny is 20 years, Lynn is 14 years and Kim is 23 years.

Pa brainlest po plsss
Answer: 8 days
Step-by-step explanation:
1) Set up an equation. Let x be the day
3,500 >= 2(816) + x(100+95)
The 816 is just two times (Plane ticket back and forth) so it doesn't go into the x. 100 and 95 do as it is one day.
2) Solve the equation
3,500 >= 2(816) + x(100+95)
1868 >= 195x
9.57 >= x
3) Rounding
Since the x has to be less than 9.57, our next option is 8
If the measure of angle 1 = 2x+3 and the measure of angle 2 = 3x+2, then what is the measure of angle 3?
Answer: 126°
Step-by-step explanation:
Step-by-step explanation: Since every triangle has 180 interior degrees, we can say 2x + 3x + 90° = 180°. Subtract 90° from each side and we get
2x + 3x = 90°
5x = 90°
x = 18°
Plug in x for Angle 2, giving us Angle 2 = 54°
Angle 1 and angle 2 must add up to 180°
Subtract 54° from 180° and we get 126°

What are the equations of lines m and q?
Equation of 'm'
(y - 6) = - ³/₅ (x - 2) [point-slope form]
y = - ³/₅ x + ³⁶/₅ [slope-intercept form]
Equation of 'q'
(y - 6) = ⁵/₃ (x - 2) [point-slope form]
y = ⁵/₃ x + ⁸/₃ [slope-intercept form]
How to find the equations of lines m and q?To find the equation for both 'm' and 'q' requires a bit of work. Because neither 'm' nor 'q' has two points to find the slopes of the line, we have to get creative.
The Line 'n' has two points [ (4, 4) & (1, -1) ], and as such we can find the slope of that line. The line 'n' is parallel with 'q' and perpendicular with m.
For finding the slope of 'n'
The slope of the 'n' = (y₂ - y₁) ÷ (x₂ - x₁)
= (4 - (- 1)) ÷ (4 - 1)
= 5 ÷ 3
= ⁵/₃
To estimate the slope of 'q' and 'm'
When two lines exists parallel, they contain the exact slope.
Since 'n' and 'q' exists parallel,
then the slope of q = ⁵/₃
When two lines exists perpendicular, the product of their slopes exists -1. This means that the slopes exists negative-reciprocals of each other.
Since 'n' and 'm' exists perpendicular
then the slope of m = - ³/₅
Write the equation for 'q' and 'm'
We can now utilize the point-slope form (y - y₁) = m(x - x₁)) to write the equation for the lines
For both 'q' and 'm' let (x₁, y₁) be (2, 6)
Equation of 'm'
(y - 6) = - ³/₅ (x - 2) [point-slope form]
y = - ³/₅ x + ³⁶/₅ [slope-intercept form]
Equation of 'q'
(y - 6) = ⁵/₃ (x - 2) [point-slope form]
y = ⁵/₃ x + ⁸/₃ [slope-intercept form]

When solving an equation with one variable on both sides what are three types of solutions youcan obtain?
whenever you have an equation with one variable on both sides, you might end up with one of the following case:
1. You might end up with an inconsistent equation, therefore there is not solution. Example
x = x+3. If you subtract x on both sides, you get 0=3 which is impossible.
2. You might end up having infinite solutions. Example:
x+6 = x+6. If you subtract x on both sides you get 6 =6 which is true regardless of the value of x.
3. You might end up having only one solution. Example:
3x +2 = x +5
If you subtract x on both sides and subtract 2 on both sides, you get
2x = 3.
then if you divide by two on both sides, you find
x = 3/2. So this equation has one unique solution.
