exis [7]

Answer:

  • 93/481

Step-by-step explanation:

<u>Total number of integers from 300 through 780, inclusive:</u>

  • 780 - 299 = 481

<u>Number of integers with at least one of digit 1:</u>

  • Hundreds - 0,
  • Tens - 5*10 = 50 (31th, 41th, 51th, 61th, 71th)
  • Units - 4*9 + 7 = 43 (300 till 699 and 700 till 780)
  • So in total 50 + 43 = 93

<u>The probability is:</u>

  • P = favorable outcomes/total outcomes = 93/481

Find the output (y) of the function y=6x+4 if the input (x) is 2
Dmitry_Shevchenko [17]

Answer:

f(2) = 16

or

y = 16

Step-by-step explanation:

Step 1: Write out function

y = 6x + 4

Step 2: Define variable for problem

<em>x</em> = 2

Step 3: Plug into function f(x)

f(2) = 6(2) + 4

f(2) = 12 + 4

f(2) = 16

Step 4: Change f(2) to y

y = 16

k = 2(27/16) = 27/8

v = (27/8)(3^2)/(2^3 = (27/8)(9/8) = 243/64

v = 243/64 when x=3 and y=2
