Answer:

<h2>b=2</h2>

Option A is the correct option.

Solution,

4 - 2(b - 6) = 12 \\ or \: 4 - 2b + 12 = 12 \\ or \: 4 + 12 - 2b = 12 \\ or \: 16 - 2b = 12 \\ or \:  - 2b = 12 - 16 \\ or \:  - 2b = -  4 \\ or \: b =  \frac{ - 4}{ - 2}  \\ b = 2

Hope this helps...

Good luck on your assignment..

Answer:

Cricket match toss and playing cards

Step-by-step explanation:

Example 1: Cricket match toss

<em>There are two teams in a cricket match. Each team's captain comes forward for the toss. There are 2 sides of the coin; head an tail. Each captain has an equal chance of either getting a head or a tail.</em>

Total number = 2

Chances of head/tail = 1

Therefore the probability for each captain of either getting a head or a tail is 1/2.

Example 2: Playing cards

<em>A deck of cards has 52 cards. There are total 26 black cards and 26 red cards out of which there are 13 clubs, 13 spades, 13 hearts and 13 diamonds. Each category has a King, Queen, Jack, Ace, 2, 3, 4, 5, 6, 7, 8, 9 and 10 card.</em>

Total number of cards: 52

Total number of 10 of spades: 1

The probability of getting a 10 of spades will be 1/52.

Answer:

A

Step-by-step explanation:

If you follow the dotted lines and bring all the lines together,

angle8 = angle4 (corresponding angles)

angle8 = angle5 (vertically opposite angles)

angle5 = angle1 (corresponding angles)

Therefore, angle8 is basically the same as angles 1 and 4

Thus,

127+127=254
