Answer:

x=1-5√3, x=1+5√3

Step-by-step explanation:

-3x^2 + 224 = — 6х + 2

add 6 on both sides

-3x^2+224+6x=2

subtract 2 on both sides

-3x^2+222+6x=0

rearrange for the quadratic formula

-3x^2+6x+222=0

use the quadratic formula

x=1-5√3, x=1+5√3

The interpretation is: the probability of selecting a male provided that a person with blue eyes has been selected

Solving (b): is (a) the same as P(B|M)

No, they are not the same.

The interpretation of P(B|M) is: the probability of selecting a person with blue eyes provided that a male has been selected

The combination for opening a safe is a four-digit number made up of different digits. How many different comninations can you m
morpeh [17]

There are 625 different 4-digit codes only made with odd numbers.

<h3></h3><h3>How many different combinations can you make?</h3>

To find the total number of combinations, we need to find the number of options for each one of the digits.

There are 4 digits, such that each digit can only be an odd number.

  • For the first digit, there are 5 options {1, 3, 5, 7, 9}
  • For the second digit, there are 5 options {1, 3, 5, 7, 9}
  • For the third digit, there are 5 options {1, 3, 5, 7, 9}
  • For the fourth digit, there are 5 options {1, 3, 5, 7, 9}

The total number of different combinations is given by the product between the numbers of options, so we have:

C = 5*5*5*5 = 625.

There are 625 different 4-digit codes only made with odd numbers.
