The probability of a biased coin landing on heads is 2/7 complete the tree diagram
mamaluj [8]

Answer:

The numbers needed to fill each box are in the image attached

Step-by-step explanation:

The probability of the coin landing on heads is 2/7, so the probability of it landing on tails is 1 - 2/7 = 5/7

The probability of landing heads 2 times is:

P = (2/7) * (2/7) = 4/49

The probability of landing heads and then tails is:

P = (2/7) * (5/7) = 10/49

The probability of landing tails and then heads is:

P = (5/7) * (2/7) = 10/49

The probability of landing tails 2 times is:

P = (5/7) * (5/7) = 25/49

The numbers needed to fill each box are in the image attached.

Complete a factor tree and a ladder diagram to find the prime factorization of 54
kodGreya [7K]
     Factor Tree
             54
          6  ×  9
      2 × 3   3 × 3
54 = 2 × 3 × 3 × 3 = 2 × 3³

2|54
  3|27                  → 54 = 2 × 3 × 3 × 3 = 2 × 3³
    3|9
       3
I'm not sure about ladder method... is it the same as upside down division.
Begin with a prime number that will divide into the number.

Solve the following:<br> a) 4x – 3 = 2x + 7<br> b) 2x + 6 = 7x - 14
pickupchik [31]

Answer:

a) x = 5

b) x = 4

Step-by-step explanation:

a) 4x - 3 = 2x + 7                                      collect like terms

   4x - 2x = 7 + 3                                    

   2x = 10                                                 divide both sides by the coefficient of x

   x = 5

b) 2x + 6 = 7x - 14                                     collect like terms

   2x - 7x = -14 - 6

   -5x = -20                                        divide both sidess by the coefficient of x

   x = 4

Equation for 2:

y = 1x + 2.

Equation for 3:

y = 2
