Answer:

median

Step-by-step explanation:

the median would make the score as good as possible, because there could be possible outliers. this really depends on if there are outliers or not. here is an example of what i need:

say you are trying to show your parents your grades:

here are your scores:

38, 88, 90, 91, 93, 95, 100

the median would be 91, which looks better.

the mean would be 85.

even though a majority of your grades are good, the one 38 makes the average go down. therefore, the median is a better advertiser.

Answer:  You will need to find the x-intercepts and the vertex

Step-by-step explanation: Use the information in the factors and some formulae.

The x- intercepts are the points where the parabola crosses the x-axis. The x-axis is where y = 0

Set each factor equal to 0 and solve:

x-2=0, so x = +2 and x +4 = 0, so x = -4    (you would plot these if creating the graph)

To find the vertex you need the Vertex Formula: x = -b/2a

b is the coefficient of the x term in the middle of the quadratic equation; you can just do the O and I parts of FOIL to get b:  -2x + 4x = 2x  You know a = 1 because x²  will have the implied (missing)(1).

Put the numbers in the Formula: x = -b/2a   x = -(2)/2(1)  -2/2 = -1  

-1 is the "x-value" of the vertex.  

The y value is the 'c' in the quadratic formula. You get that from the  L part of FOIL   -2 × 4 = -8 .

So, your coordinates for the vertex:  ( -1, -8 )

If you were creating a graph, you would plot that point, then draw the parabola starting there and through the x-intercepts.

Step-by-step explanation:

there could be no red cards inside

A binomial random variable is no since the total number of red cards in the deck is unknown at the start of the experiment.

We have to determine whether the card player selects a playing card from a well-shuffled deck of standard playing cards and sees if the card is a red card or not.

He keeps the card, and then makes another selection and sees if the card is a red card or not.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

He continues this process 10 times and counts the total number of red cards that he selects.

We have to determine if it Is a binomial random variable.

There could be no red cards inside.

Therefore, A binomial random variable is no since the total number of red cards in the deck is unknown at the start of the experiment.

The green triangle is rotated  

✔ 90

degrees to form the blue triangle.

Triangle QRS is rotated  

✔ 180

degrees to form the image triangle JKL.

Step-by-step explanation:

have a nice day because I said so but mostly because you want to

The green triangle is rotated 90 degrees to form the blue triangle. And ΔQRS is rotated 180 degrees to form the image of ΔJKL.

" Coordinate plane is also known as cartesian plane in two dimensional , which is represented by intersection of two axis at 90°, the horizontal axis is known as x-axis and vertical axis is known as y-axis."

According to the given question,

Here all triangles are right angled triangle.

All triangles are perpendicular to the respective axis as per diagram.

Rotation of triangle on coordinate plane from one axis to another forms 90°.

Hence, we conclude that the green triangle is rotated 90 degrees to form the blue triangle. And ΔQRS is rotated 180 degrees to form the image of ΔJKL.

--> x = 88

Answer:

[tex]x=88[/tex]

Answer:

Step-by-step explanation:

P = 2w + 2l

l = 2w

48 = 2w + 2×2w

48 = 2w + 4w

48 = 6w

w = 48 : 6

w = 8 inches

l = 2w

l = 2×8inches

l = 16 inches

A = w×l

= 8in × 16in

Answer:

Step-by-step explanation:

Answer:

28 degrees

Step-by-step explanation:

Because a triangle equals 180, you can subtract 90 and 34 from triangle ABE to leave you with 56 degrees for angle B.

Since CBA is a straigth line with 180 degrees, you can subtract 56 to end up with 124 degrees for angle CBE.

Since line BD bisects angle EBC (splits in half), you can divide the 124 degrees into 62 degrees.

Now that we know angle CBE equals 62 degrees, we can add the 90 degrees and subtract them from the 180 degrees of the triangle.

62+90=152

180-152=28

Answer:

The correct option is;

RT = 35°

Step-by-step explanation:

Given the parameters are;

∠SMX = 95°

∠MXS = 45°

arc PW = 80°

arc WY = 35°

From external angle half difference formula, we hve;

Given an external angle, ∠MSX, subtending a far arc x° and a near arc y°, then we have;

∠MSX = 1/2×(x° - y°)

Where:

x° = arc PW + arc WY = 80° + 35° = 115°

y° = arc RT

∠MSX  + ∠SMX + ∠MXS = 180° (Sum of interior angles in a triangle)

∠MSX  = 180° - (∠SMX + ∠MXS) = 180° - (95° + 45°) = 40°

Therefore;

∠MSX = 1/2×(x° - y°) gives;

40° = 1/2×(115 - y°)

y° = 115° - 2 × 40° = 35°

∴y° = 35° = arc RT.
