Answer:

Results:

0.1432

0.0045

0.0905

0.0483

Step-by-step explanation:

Step a:

P(A or 10, A or 10) = 20/52 * 19/51 = 5/13 / 19/51 = 95/663 = 0.1432

Step b:

P(A A) = 4/52 * 3/51 = 1/13 * 1/17 = 1/221 = 0.0045

Step c:

P(10 10) = 16/52 * 15/51 = 4/13 * 5/17 = 20/221 = 0.0905

Step d:

P(A 10 or 10 A) = 2 * 4/52 * 16/51 = 2/13 * 16/51 = 32/663 = 0.0483

As well we get the probability by subtracting a, b and c:

P(blackjack): 0.1432 - 0.0905 - 0.0045 = 0.0482

Given the equation 2(3x − 4) = 5x + 6, solve for the variable. Explain each step and justify your process.

blagie [28]

2(3x-4) = 5x+6
First, expand the bracket.
6x-8=5x+6
Next, move the variables to the same side.
x-8=6
Move the -8 to the other side, change to +
x=6+8
x=14
Charlie’s solution is incorrect. When expanding the bracket, he changed the - to a +.

Answer:

Tim will get £ 8

Sam will get £ 32

Solution,

let the ratios be x and 4x

 $x + 4x = 40 \\ or \: 5x = 40 \\ or \: x = \frac{40}{5} \\ x = 8 \\ replacing \: value \\ 4x \\ = 4 \times x \\ = 4 \times 8 \\ = 32$
