Answer:
1) 19/25 likely
2)5/25 unlikely
3) 2/25 = 8%
I have to go so I cant finish 4 and 5 but I hope this helped
Step-by-step explanation:
1) this is based just on the results so we don't have to do any probability tree or anything. there are 25 groups overall and 19 of those 25 groups contain at least one senior. this is 76% and is over 2 thirds so it is likely
2) again this is based just on the results so we don't have to do any probability tree or anything. there are 25 groups overall and 5 of those 25 groups contain at least 2 freshmen. this is 20% and is under 1 third so it is unlikely
3)again this is based just on the results so we don't have to do any probability tree or anything. there are 25 groups overall and 2 of those 25 groups contain four students from the same grade level. this is 8% and so is unlikely.

[tex]C' = (2,8)[/tex]
[tex]A' = (4,4)[/tex]
[tex]T' = (10,10)[/tex]
Step-by-step explanation:
Given
[tex]k =2[/tex]
[tex]C =(1,4)[/tex]
[tex]A = (2,2)[/tex]
[tex]T =(5,5)[/tex]
Solving (a): The new points
To do this, we simply multiply the old points by the scale factor.
i.e.
[tex]New = Old * k[/tex]
So:
[tex]C' = (1,4) * 2 = (2,8)[/tex]
[tex]A' = (2,2) * 2 = (4,4)[/tex]
[tex]T' = (5,5) * 2 = (10,10)[/tex]

Kaitlyn is walking on a treadmill at a constant pace for 36 minutes. She has programmed
the treadmill for a 2-mile walk. The display counts backward to show the distance
remaining.
Enter and graph the equation that gives the distance f(x) left in miles as a function of the
number x of minutes she has been walking. Then, find and compete the interpretation of
the x- and y-intercepts.
The equation is f(x) =
Answers
Answer:
x int = (36,0)
y int = (0,2)
Step-by-step explanation:
Speed = distance / time
speed = 2/36 = 0.05555 Or 1/18 (as a fraction)
equation = f(x) = 2 - x/18
graph
The equation that gives the distance f(x) left in miles as a function of the number x of minutes she has been walking is [tex]f(x) = -\frac{x}{18} + 2[/tex]
The x-intercept of the graph is at (0, 2) which shows that the distance traveled at the beginning is 2 miles
The y-intercept of the graph is at (36, 0) which shows that no distance was covered when at when the time is 36 minutes
The general equation that represents the graph is expressed as:
[tex]f(x) = 2 - sx[/tex]
s is the speed of Kaitlyn
The formula for calculating the speed is expressed as;
[tex]speed = \frac{distance}{time}[/tex]
The function required will become;
[tex]f(x) = 2 - \frac{d}{t}x\\[/tex]
Given the following parameters
distance "d" = 2 miles
Time "t" = 36 minutes
Substitute the given parameters into the function as shown:
[tex]f(x) = 2 - \frac{2}{36}x\\f(x) = 2 - \frac{1}{18}x\\f(x) = -\frac{x}{18} + 2[/tex]
Hence the equation that gives the distance f(x) left in miles as a function of the number x of minutes she has been walking is [tex]f(x) = -\frac{x}{18} + 2[/tex]
Get the y-intercept of the function:
If x = 0
[tex]f(x) = -\frac{0}{18} + 2\\f(x) = 2[/tex]
The y-intercept of the function is (0, 2)
Get the x-intercept of the function
[tex]0 = -\frac{x}{18} + 2\\-2 = -\frac{x}{18} \\x = 36[/tex]
Hence the x-intercept of the graph is expressed as (36, 0)

2. Is there a different triangle Diego could have drawn that would answer the question? Yes as long as it has two 45 degree angles and a side length of 8 cm
Diego answer is correct.
The other form of triangle can be Right angled triangle.
What is Right Angles Triangle?A right-angled triangle is a triangle in which one of the angles is 90 degrees. The sum of the other two angles is 90 degrees. The sides that include the right angle are perpendicular and form the triangle's base. The third side is known as the hypotenuse, and it is the longest of the three sides.
Diego made the triangle with base angles 45 degree each and base length of 8 cm.
Yes. I agree with Diego answer.
but this is not the only triangle can be made.
As, two of the angle is 45 degree then the third angle must be 90 degree which is a right angle with Hypotenuse 8 cm.

If h = 7 units and r = 3 units, then what is the volume of the cone shown above?
Answers
Answer:
Step-by-step explanation:
h = 7 units
r = 3 units
Volume of cone = (1/3) *πr²h
[tex]= \frac{1}{3}* \frac{22}{7}*3*3*7\\\\= 22 *3\\\\= 66 cubic units[/tex]
If h = 7 units and r = 3 units, then what is the volume of the cone shown above ?
Answer:-Given:-[tex] \bullet [/tex] Height (h) of the cone is 7 units.
[tex] \bullet [/tex] Radius (r) of the cone is 3 units.
To Find:-The volume of the cone.
Solution:-We know,
Formula of volume of cone is [tex]\frac{1}{3} [/tex]πr²h
So, Volume of the cone = [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × (3)² × 7
= [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × 9 × 7
= [tex] \frac{22 \: × \: 9 \: × \: 7}{3 \: × \: 7} [/tex]
= [tex] \frac{1386}{21} [/tex]
= 66 cubic units.
