Answer 1

Answer:

[tex]\Huge\boxed{x=42}[/tex]

Step-by-step explanation:

Hello There!

The shown angles are supplementary angles.

We know this because a straight line is split into two angles

A straight line creates a 180 degree angle so the sum of the two angles is 180

So we can use this equation to solve for x

180 = 3x + 12 + x

3x + x = 4x

180=4x+12

step 1 subtract 12 from each side

180-12=168

12-12 cancels out

now we have

168=4x

step 2 divide each side by 4

4x/4=x

168/4=42

we're left with x = 42

The following cards are used in a game. If each of the cards is turned over and shuffled, then how much of a greater chance is there in drawing a spade over drawing a 7?

Answers

Answer:

1/6 of a chance aka 16.666?%

Step-by-step explanation:

The probability of drawing a card with number 7 is 0.166.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

From the given set of cards,

Total number of cards =6

Number of spades = 3

Number of card with number 7 on it = 1

Probability of drawing a 7 = 1/6

= 0.166

Therefore, the probability of drawing a card with number 7 is 0.166.
