Edison, Xiu, and Amia are childhood friends who go to different high schools. They were wondering if there's
a difference between their schools in the number of friends people have on social media.
They each surveyed a random sample of students from their schools, asking for the number of friends they
have on social media. Here are the results:
They want to perform a x2 test of homogeneity on these results.
What is the expected count for the cell corresponding to students from Edison's school that have more
than 300 friends?

triangle abc is similar to triangle fgh solve for x
Answer:
A= 24
Step-by-step explanation:
First find the scale factor. so the scale factor for these two triangles is 1.5.
21 / 14 = 1.5
18 / 12 = 1.5
So you are going to multiply 16 x 1.5
That will give you 24.

Andre and Mai are discussing how to solve for side AB. Andre thinks he can
use the equation tan(12 degrees)=x/6 to solve for AB. Mai thinks she can use
the equation tan(78 degrees)=6/x to solve for AB. Do you agree with either of
them? Show or explain your reasoning.
Answer:
Both Andre and Mai are correct
Step-by-step explanation:
A drawing of the the triangle ΔABC is created with MS Visio and attached here
In the drawing, we have;
Segment AB = x
Segment AC = 6
By trigonometric ratio, in a right triangle we have;
[tex]Tan(\angle X) = \dfrac{The \ length \ of \ the \ opposite \, side \ to \ \angle X }{The \ length \ of \ the \ adjacent\, side \ to \ \angle X}[/tex]
Where 'X' = 12° as shown in the figure, we have;
[tex]tan(12 ^{\circ}) = \dfrac{AB}{BC} = \dfrac{x}{6}[/tex]
Therefore, Andre is correct
Similarly, we have;
[tex]tan(78 ^{\circ}) = \dfrac{BC}{AB} = \dfrac{6}{x}[/tex]
Therefore, Mai is also correct
Therefore, Andre and Mai are correct.

Colin invests £1100 into his bank account. He receives 5% per year simple interest. How much will Colin have after 6 years? Give your answer to the nearest penny where appropriate.
Answer:
Step-by-step explanation:
P = £1100
r = 5%
t = 6 years
I =P*r*t
[tex]I =1100*\frac{5}{100}*6\\\\I=11*5*6\\\\I = 330[/tex]
Amount = P + I = 1100 + 330 = £1430

solve 2x+2y=-4, 6x-2y=12 using Elimination
NO LINKS (i need the steps not just the answer)
Answer:
2x+2y=-4
since we don't know the value of the letters, we could ignore it. then we add 2+2 which equals 4
6x-2y=12
In this case this equation is incorrect.

Answer:
(1,-3)
or
x=1 y= -3
Step-by-step explanation:
Looking at this we can see that there's a 2y in both of the equations (one is negative while the other is positive and so we'll add them)
so we have
(2x+2y)+(6x-2y)= -4+12
this simplifies to
8x=8
x=1
We know that x=1 and so we will plug this back into one of the two equations
2(1)+2y= -4
2+2y= -4
2y= -6
y= -3
Therefore the solution is (1,-3)
Find the area of the following rectangle. Type out al work
Step-by-step explanation:
[tex]area = length \times width \\ = (4x + 3) \times (2x + 2) \\ = ( {8x}^{2} + 8x + 6x + 6) \\ = ( {8x}^{2} + 14x + 6) \: {units}^{2} [/tex]
Answer:
[tex](8x + 14x + 6)^{2}[/tex]
Step-by-step explanation:
Area of a rectangle is length x breadth
In the given figure, the length is 2x + 2 and breadth is 4x + 3
So, the area would be:-
(2x + 2) (4x + 3)
[tex]8x^{2}[/tex] + 6x + 8x + 6
So the area would be => [tex](8x + 14x + 6)^{2}[/tex]
Find the area of the shape.

Find the values of x and y. Write your answers in simplest form.
Answer:
x = 4
y = 2√2
Step-by-step explanation:
This triangle can be recognized as a 45 - 45 - 90, right isosceles triangle. The hypotenuse in a right isosceles triangle is √2 times a leg. We can say:
x = √2 * 2√2
x = 4
Since the triangle is isosceles, we can say the legs are equal, therefore:
y = 2√2
Which two-dimensional shape could be created by a plane
slicing vertically through this hemisphere?
Answer:
circle
Step-by-step explanation:
A semicircle could be created by a plane slicing vertically through a hemisphere.
What is geometry?Geometry is the description of figures in a space with a specific number of dimensions and types. Plane geometry is the most prevalent sort of geometry (dealing with objects like the point, lines, circles, triangles, and polygons),
The plane would cut through the middle of the hemisphere, creating a circle with half the diameter of the original hemisphere. This circle is the base of the semicircle and the curved surface of the hemisphere forms the arc of the semicircle.
Thus, a semicircle could be created by a plane slicing vertically through a hemisphere.

A jar has 28 cherry-flavored candies, 19 strawberry-flavored candies, 20-orange flavored candies, and 33 lemon-flavored candies. If a candy is taken from the jar at random, what is the probability that it will be a cherry-flavored cnady?
Answer: 7/25 or 28%
Step-by-step explanation:
28 (cherry) + 19 (strawberry) + 20 (orange) + 33 (lemon) = 100 (total)
so p(cherry), or the probability of getting cherry, is 28/100 (7/25)
that as a percent is 28%
