Answer:

  • x = 1.25
  • y = 1.75

Step-by-step explanation:

Find x

  • 8/10 = 5/(5 + x)          Cross multiply
  • 8*(5 + x) = 10*5          Combine on the right
  • 8(5 + x) = 50              Remove the brackets on the left.
  • 40 + 8x = 50              Subtract 40 from both sides.
  • 40-40 +8x = 50-40    Combine
  • 8x = 10                        Divide by 8
  • 8x/8 = 10/8                 Divide
  • x = 1.25

Find y

  • 7/(7 + y) = 8/10                    Cross multiply
  • 8*(7 + y) = 10 * 7                  Combine the right
  • 8(7 + y) = 70                        Remove the brackets.
  • 56 + 8y = 70                       Subtract 56 from both sides
  • 56 - 56 + 8y = 70 - 56       Combine
  • 8y = 14                                Divide by 8
  • y = 1.75

I need help please and thanks
dimulka [17.4K]

Answer:

10

Step-by-step explanation:

n is the number of selections and k the number selected, that is

n = 5 and k = 2

note that n! = n(n - 1)(n - 2) ..... × 3 × 2 × 1, thus

\frac{5(4)(3)(2)(1)}{2!(5-2)!}

= \frac{120}{2(1)3(2)(1)}

= \frac{120}{2(6)}

= \frac{120}{12}

= 10
