Which scatter plot below shows both linear association and negative association between the two variables?
Answer:
C
Step-by-step explanation:
It is C because negative means it will be going down so it isnt A or B and you can see D has a curve up before it goes down so C is the best answer

- Three athletic clubs offer different membership costs. The first club charges $20
per month. The second club charges $20 per month plus an application fee of
$10. The third club charges $20 per month and offers a $15.00 reduction in the
first month's membership fees. Write the equations that model the total cost of
membership at the three clubs. Describe how the second and third graphs are
related to the graph of the first club.
In order to complete a large job, 1000 workers were hired, just enough to complete the job on schedule. All the workers stayed on the job while the first quarter of the work was done, so the first quarter of the work was completed on schedule. Then 100 workers were laid off, so the second quarter of the work was completed behind schedule. Then an additional 100 workers were laid off, so the third quarter of the work was completed still further behind schedule. Given that all workers work at the same rate, what is the minimum number of additional workers, beyond the 800 workers still on the job at the end of the third quarter, that must be hired after three-quarters of the work has been completed so that the entire project can be completed on schedule or before?

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.

Answer:
5/6
Step-by-step explanation:
create a proportion:
(1/2÷3/5) = (x÷5/5)
cross-multiply to solve for 'x':
3/5x = 1/2
6x = 5
x = 5/6
Answer:
[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Ok so one hour is 1/1.
1/1 - 3/5 = 2/5
So Landon has 2/5 of an hour left.
Let's find out how much 1/5 of an hour is in the test.
1/2 ÷ 3 = 1/6
So 1/5 of an hour = 1/6 of the test.
1/6 * 2 = 1/3
1/2 + 1/3 = 5/6

PLEASE HELP WITH ALGEBRA!!!
Answer: aₙ = 3 + 4ⁿ⁻¹
So the formula would be:
aₙ = 3 + 4ⁿ⁻¹
Where a₁ = 3
Common Ratio (r) = 4
And n = the term number that needs to be found out
Step-by-step explanation:
Let's check if the answer is right:
To find the 1st number in the term we can substitute 1 in for n in the equation:
a₁ = 3 + 4¹⁻¹
a₁ = 3 + 4⁰
a₁ = 3 + 1
a₁ = 4
And if going back and checking the first number in the sequence given is indeed 4, therefore this equation is correct

The cylinder is 20cm high and radius of its circular face is 3cm What is the total perimeter and area of the whole net?
Answer: [tex]52\ cm,\ 176.55\ cm^2[/tex]
Step-by-step explanation:
Given
The cylinder is 20 cm high
The radius of the cylinder is [tex]r=3\ cm[/tex]
The total area of the figure is the sum of the rectangle and two circles
[tex]\Rightarrow \text{Perimeter P=}2[h+2r]\\\Rightarrow P=2[20+6]\\\Rightarrow P=52\ cm[/tex]
The total area of the figure is
[tex]\Rightarrow \text{Area A=}h\times 2r+2\pi r^2\\\Rightarrow A=20\times 6+2\times \pi \times 3^2\\\Rightarrow A=120+18\pi\\\Rightarrow A=176.55\ cm^2[/tex]

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.
can any of you help me with this? Like fast?
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.
can someone please help me with this i got school tmr
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°
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.

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 :)

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
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)

Step-by-step explanation:
Complete Question
A committee consisting of 2 faculty members and 4 students is to be formed. Every committee position has the same duties and voting rights. There are 6 faculty members and 10 students eligible to serve on the committee. In how many ways can the committee be formed?
Solution
Total Faculty members = 6
Total Students = 10
Out of 6 faculty members, 2 will be chosen for the committee
While 4 students will be chosen out of 10 to be in the committee.
Hence,
Total number of ways of making the core committee = 6C2 * 10C4
= 15*210
= 3150
