Answer: 17 degrees
Step-by-step explanation: Because you have angle A= 163, you can tell that angle B is 17 degrees (sum of angles on one side of a straight line add up to 180). Line M and line N are parallel, so they have corresponding angles, making angle B and angle X are the same. See picture attached for my diagram :). hope this helped!

Determine the five-number summary for the data set. 20, 26, 18, 31, 22, 28, 30
Answer:
min = 18Q1 = 20median = 26Q3 = 30max = 31====================================================
Explanation:
The first task is to sort the items given.
The sorted set is {18, 20, 22, 26, 28, 30, 31}
There are 7 values in that set. The median is going to be in slot 4 because n/2 = 7/2 = 3.5 rounds to 4.
The value in slot 4 is 26, meaning the median is 26.
There are 3 values below the median, and 3 values above it.
L = lower set = items below the median
L = {18,20,22}
U = upper set = items above the median
U = {28,30,31}
The median of set L is 20, showing that Q1 = 20 is the first quartile.
The median of set U is 30, meaning Q3 = 30 is the third quartile.
The min and max are exactly what they sound like: they are the smallest and largest items. In this case, we have min = 18 and max = 31.

Answer:
Based on the linear regression equation, the intercept means that for 0 missed classes, the expected test score is 98✓we know that,
y intercept exist when x = 0
so,
⇢y = -4x +98
⇢y = -4 x 0 +98
⇢y = 98
so , the expected test score is 98
Based on the linear regression equation, the slope means that for every missed class, the expected tast score decreases by 4 points✓when x = 0
y = -4(0) +98
when x = 1
y= -4(1) +98 = 94
when x = 2
y= -4(2) +98 = 90
we can see the decresement of 4 points
Based on the linear regression equation, as the number of days a student misses class increases the expected test score decreases ✓We can see that the increament in absent days lead to lower scores ( one class = 4 points)
For 0 clases
y=-0+98=98Option A is certified as correct
Here slope is -4So it decreasing not increasing
Option C is correct
Yes as the missed classes increase expected test decreasing as slope is negative.
Option F is correct

A group of students must collect at least $150 to organize a science fair. They have already collected $30. Which graph best represents all remaining amounts of money, in dollars, that the students should still collect to organize the science fair?
Number line graph with a closed circle on 120 and shading to the right.
Number line graph with a closed circle on 30 and shading to the right.
Number line graph with a closed circle on 150 and shading to the right.
Number line graph with a closed circle on 180 and shading to the right.
Answer:
Number line graph with a closed circle on 120 and shading to the right.
Step-by-step explanation:
Because they have collected 30 dollars already and must collect at least 150 dollars, the closed circle would go on 120, going to the right. (150-30=120)
There are 135 people in a sport centre.
73 people use the gym.
59 people use the swimming pool.
31 people use the track.
19 people use the gym and the pool.
9 people use the pool and the track.
16 people use the gym and the track.
4 people use all three facilities.
Given that a randomly selected person uses at least two facilities, what is the probability they
use all the facilities?
Answer:
1/9
Step-by-step explanation:
4 people use all three facilities, then
16 - 4 = 12 people use the gym and the track and do not use the pool;
9 - 4 = 5 people use the pool and the track and do not use the gym;
19 - 4 = 15 people use the gym and the pool and do not use the track.
At least two facilities use 4 + 12 + 5 + 15 = 36 people, 4 of them use all three facilities. Thus, the probability that a randomly selected person which uses at least two facilities, uses all the facilities is 4/36 which is equivalent to 1/9

The next step is to to construct a line through point R is the option;
Place the compass on point T. without changing the setting from the previous step, draw a small arc above [tex]\overleftrightarrow{ST}[/tex]What are the steps to construct a perpendicular to a line?
The steps to construct a perpendicular through the point R are;
Place the compass at point R and draw an arc intersecting the line ST at the point S and T.Place the compass at point S and draw the arc given in the drawing.Place the arc at point T and without changing the setting draw an arc above the line ST to intersect the previous arc.Join the point of intersection of the arcs to the point R to complete the construction of the perpendicular to the line ST passing through RThe step that should be taken next to construct a line through point R that is perpendicular to [tex]\overleftrightarrow{ST}[/tex] is therefore;

y=-⅓x+4 what is this treasure of change?
Please Help!
Answer:
-1/3
Step-by-step explanation:(if treasure of change is "rate of change")
Equation of a line: mx + b
m=-1/3: slope
b: y-intercept
^Whenever working with an equation of slope/rate of change the above variables have specific meanings.
Slope is another term for rate of change so the rate of change would be -1/3.
m=-1/3=slope/rate of change
b=4=y intercept

Let g(x) = 3(x - 6)^2 + 1. Find the range of $g$.
Answer:
[1,∞)
Step-by-step explanation:
Let's try to plug in some numbers.
When solving a problem fo range, the best place to start is where you can let the (x - b) part = 0.
This is what I mean
3(x-6)² + 1
Let x = 6
3(0)² + 1 = 1
Look how we have a 0 inside the parentheses.
That's what I mean.
Now let's try using terms smaller than 6.
Now, let's try plugging in 5
3(-1)² + 1 = 4
Now try plugging in 4
3(-2)² + 1 = 13
Looks like we will just keep going up.
Now let's try using terms bigger than 6.
Plugging in 7
3(1)² + 1 = 4
Plugging in 8
3(2)² + 1 = 13
We just go up both ways because of the x squared term.
So our smallest value is at x = 6 where we have y = 1.
If we go either direction forever to the right or left the terms to get bigger, where it approaches infinity.
So, 1 will have parentheses as it can be reached and infinity will have parentheses as it is unreachable and goes on forever.

What is the simplified product in standard form?
px +
62 +
Answer:
Step-by-step explanation:
Multiply: (3x - 5)(-x + 4)
By applying the distributive property,
(3x - 5)(-x + 4)
= (3x)(-x) + (3x)(4) - (5)(-x) - (5)(4)
= -3x^2 + 12x + 5x - 20
= -3x^2 + 17x - 20
That is the simplified product in standard form.

Answer:
(m+n)*6
Step-by-step explanation:
The total area of a rectangle= length*breath
So using this,
Length (l)=n+m
Breath (b)= 6
We know that,
Area of rectangle (A)=l*b
=(n+m)*6
=(n+m)6
