Answer:
In the graph, we have a linear fit of the student's grades as a function of the number of hours they say that they study.
Then the y-axis represents the grade, and the x-axis represents the number of hours of study, and because this is a linear fit, we will have something like:
y = a*x +b
If we input a value of x here (number of hours studied) we would get the expected grade for the weekly quiz y.
In this situation, the meaning of the x-value on the line when y = 75 would be the (adjusted) number of hours studied to get a grade of 75.
So this x-value is the average number of hours that a student needs to study to get a grade of 75 points.

2. Aaron baked two identical cakes. He cut one into 9 equal slices and the other into 19 equal slices.
a) Show that ⅔ of the 9-slice cake gives the asme number of pieces as 1/
3 of the 18 slice cake.
2/3 x 9 = 6 slices
1/3 x 18 = 6 slices
Hence they give the same number of slices.
Dave Goes into a car and buys 2 cups of coffee and a piece of cake each cup of coffee cost to pound 50 5K cost £3.85 to the 10th power mode he thinks he'll get more than £1.50 change
Answer:
Dave will get £1.60 change. Hence Dave is right
Step-by-step explanation:
Complete question
Dave goes into a cafe and buys 2 cups of coffee and a piece of cake.
Each
cup of coffee costs £2.75
The cake costs £2.90
Dave pays with a £10 note.
He thinks he will get more than £1.50 in change.
Is Dave correct?
Solution
Cost of one cup of coffee = £2.75
Cost of two cup of coffee = 2* £2.75 = £ 5.5
Cost of cake = £2.90
Total amount given by Dave = £10
Amount left with Dave = £10 -£ 5.5 - £2.90 = £1.60
Dave will get £1.60 change. Hence Dave is right

(a) An angle measures 29º. What is the measure of its complement?
(b) An angle measures 26°. What is the measure of its supplement?
measure of the complement =
measure of the supplement =
Answer:
a) 61 b) 151
Step-by-step explanation:
measure of the complement = 29 + x = 90 ; x = 90-29 = 61
measure of the supplement = 29+x= 180 ; x = 180 - 29 = 151

slope = rise/run
rise = -3 ... move down 3 units
run = 4 .... move to the right 4 units
============================================
Work Shown:
m = slope
m = rise/run
m = (change in y)/(change in x)
m = (y2-y1)/(x2-x1)
m = (-17-(-2))/(24-4)
m = (-17+2)/(24-4)
m = -15/20
m = -3/4 is the slope
----------------
It basically means "move down 3 units, and move to the right 4 units"
So, slope = rise/run = -3/4
rise = -3 = move down 3 units
run = 4 = move to the right 4
You could express the slope as a decimal, and that would be -3/4 = -0.75, but you lose the rise and run values. So I recommend you keep the fraction.
Another problem with decimals is that sometimes we could have approximations that aren't exact. For example, if the slope was 2/3, then that approximates to 0.667 which may cause rounding errors down the line. Though I should point out that decimals do have their advantages in some cases.

Find the slope of the line that passes through the points
(-5,-6) and (5,10)
Answer:
8/5
Step-by-step explanation:
To find the slope given two points
m = (y2-y1)/(x2-x1)
= (10- -6)/(5 - -5)
= (10+6)(5+5)
= 16/10
= 8/5
1.6
Step-by-step explanation:
change in y ÷ change in x
(10--6)=16
(5--5)=10
16÷10=1.6
what is the sum of the probabilities of 2 complementary events
-1
0
1
0.5
Answer:
1
Step-by-step explanation:
The sum of probability of two complementary events is always equal to 1. This happens because the probability of a complementary event is always determined by deducting the probability of a given event from 1.

Here's the solution,
the opposite angles of parallelogram are equal, so, Angle G = Angle E
=》3x + 11 = 5x - 9
=》5x - 3x = 11 + 9
=》2x = 20
=》x = 10
value of x = 10
now, Angle G = 5x - 9
=》(5 × 10) - 9
=》50 - 9
=》41°
Angle G and Angle F are supplementary, so
=》 41° + Angle F = 180°
=》Angle F = 180° - 41°
=》Angle F = 139°
Recall the equation for a circle with center ( h , k ) and radius r . At what point in the first quadrant does the line with equation y = 2.5 x + 4 intersect the circle with radius 5 and center (0, 4)?
Answer: The required point = (1.857,8.643)
Step-by-step explanation:
Equation of circle with center (h,k) and radius r: [tex](x-h)^2+(y-k)^2=r^2[/tex]
Given: Radius = 5 , center = (0,4)
Eqation of circle: [tex](x-0)^2+(y-4)^2=5^2[/tex]
[tex]x^2+(y-4)^2=25[/tex]
[tex]x^2+(2.5x+4-4)^2=25[/tex] [Using equation y = 2.5 x + 4 ]
[tex]x^2+(2.5x)^2=25[/tex]
[tex]x^2+6.25x^2=25[/tex]
[tex]7.25x^2=25[/tex]
[tex]x^2=3.44827586207[/tex]
[tex]x=1.857[/tex]
[tex]y= 2.5(1.857)+4[/tex]
[tex]=8.6425[/tex]
Hence, the required point = (1.857,8.643)
A bus departed from New York at 11 pm with 44 passengers. An hour later, a few passengers got off at New Jersey. The number of passengers who boarded the bus at New Jersey were twice the number of passengers who got off the bus. If the bus has 50 passengers now, how many passengers got off at New Jersey?
Answer:
6 got off at NJ
Step-by-step explanation:
if u write an equation it would be 44-x+2x=50. -x+2x=x so the equation would now be 44+x=50. If you subtract both sides by 44, it would be x=6. x was the number of people that got off at NJ so 6 people got off there.

angles in a triangle add up to 180 degrees
the little squares in the corner mean its a right angle (90 degrees)
the two lines like in the op triangle mean the two angles downwards are the same.
angles in a semicircle add up to 180 degrees
3 lines mean all angles are the exact same
(Sorry i forgot 2 angles dont know which ones i forgot but with the info i gave you should be able to work those two out :)

Branson Creek Middle School has decided to make fitness a key message to their students in the upcoming school year. As a result, they will be participating in a national fitness program. To participate, they must randomly select 15 students in the 5th grade and record their exercise time each day. The data (in minutes) are shown.
85, 80, 76, 78, 82, 88, 80, 80, 110, 85, 85, 82, 83, 88, 76
Describe the distribution of the data.
Determine the median and mean of the data.
Which measure better represents a typical value in the data set? Explain.
Answer:
data from minimum to maximum :
76 76 78 80 80 80 82 82 83 85 85 85 88 88 110
n= 15 , so the median is X8 = 82 minutes
mean =
(76+76+78+80+80+ 80 +82+ 82+ 83+ 85+ 85+ 85 +88 +88+ 110) / 15 = (1,258)/15 = 83.87 minutes
in order to get higher standard its better use mean as a typical value.
