Help me out , plzzzzz!!

Answer:

a. 5,040 ways

b. 210 ways

Step-by-step explanation:

a) We want to pick 4 numbers out of 10 given that orders matter

If orders do matter, it will be a permutation problem

Mathematically;

n P r = n!/(n-r)!

In this case, n is 10 and r is 4

Thus, we have it that;

10 P 4 = 10!/(10-4)! = 5,040

b) if orders do not matter

It will be a combination problem

n C r = n!/(n-r)!r!

n = 10 and r = 4

10 C 4 = 10! /(10-4)!4!

= 210

Find ordered pair that is solution for liner equation 4x - 5y=20
Nat2105 [25]

Answer:

(0,-4) (5,0)

Step-by-step explanation:

4x-5y=20

First, we must put the equation into slope intercept form: y= mx+b

5y=4x-20=y=4/5x-4

The y intercept, by definition, is b. In this scenario, b is -4.

One ordered pair that works is (0,-4).

Also, we can find the ordered pair for the x intercept. By definition, the x intercept is the value of x when y equals zero. hence, we substitute 0 for y and then we can find an ordered pair that works and solve for x!:

  1. 0=4/5(x)-4= 4=4/5x
  2. 4x=20
  3. x=5

Therefore, (5,0) works as well!

The area of a square can be found using the equation A=s^2, where A is the area and s is the measure of one side of the square.
MaRussiya [10]
A = 81 square in.

s = sqrt(A)

s = sqrt(81)

s = 9 in.

HELP PLEASE! Chords NO and PQ are congruent. Arc NO measures 4x + 10 and Arc PQ measures 2x + 20. What is each of their measures
Elodia [21]
4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
x = 5
