Answer: median because there is an outlier.

1, 4, 9, 4, 10, 8, 42

Put this into order.

1, 4, 4, 8, 10, 42

It would most definitely not be the mode, because there is an outlier, and it wouldn't be the median, because once again, there is an outlier.

So, that leaves you with the mean.

The mean would measure this the best because it'll represent it the best. It is also the only one that'll fully make sense.

So, your answer is : The mean.

MAXImum [283]

Maya is said to be m years old now. We are asked what will be her age after four years from now so we just have to add 4 years from her age now. The correct expression to calculate her age should be m+4. This cannot be seen among the choices given above.

Which best describes the lateral faces of all prisms? parallelograms squares rhombi rectangles?

Murljashka [212]

Any face on a prism that is not a base is a lateral face (see the attached image). The prism in the picture has a hexagonal base (6 sided) and 6 lateral faces. The lateral faces meet each other at lateral edges, as well as meeting both bases. Each lateral face is a polygon with four sides. All edges of the laterals are the same size and parallel. This makes the lateral faces parallelograms, containing a 4-sided figure with opposite sides that are parallel.

Use binomial expansion to solve each exercise. (a) Find the coefficient of xy19 in (3x − 2y) 20.(b) Give a formula for the coeff

Answer:

(a) -29,884,416

(b) C(n,(n -k)/2) . . . where C(n,k) = n!/(k!(n-k)!) and k ∈ ℕ

Step-by-step explanation:

(a) The coefficient of the k-th term of the expansion is ...

C(20,k)(3x)^(20-k)(-2y)^k

For k=19, this is ...

19(3x)(-2y)^19 = -29,884,416xy^19

The coefficient of the term is -29,884,416.

(b) The p-th term of the expansion of (x +1/x)^n is ...

C(n,p)(x^(n-p)(1/x)^p = C(n,p)(x^(n-2p))

For some exponent k of x, the value of p will be ...

k = n -2p

p = (n -k)/2

Then the coefficient of x^k will be C(n, (n-k)/2), where C(n, x) = n!/(x!(n-x)!).

You will notice that there will only be a term x^k for k having the same parity as n.
