exclusive.

The example that I can think of is a deck of playing cards. The two events that don't have a common set would be the black card and the red card. They are mutually exclusive because there can only be two possible colors. If the card is not red, then it is black (and vice versa). There is no card that consists of both colors.

Answer : 4th option

A equation is given to us and we need to find out its graph from the options . The given equation is ,

→ y = -2x + 1

Comparing this equation to the slope intercept form of the line which is y = mx + c , where m is the slope and c is y intercept. We have ,

  • m = -2
  • c = 1

So the equation of the line will cut y axis at (0,1) and will have a negative slope .

  • Since the slope is negative , it will make an obtuse angle in anti clockwise direction with the x axis .

And the graph which satisfies the above conditions is in 4th option .

<u>Hence</u><u> the</u><u> </u><u>correct</u><u> answer</u><u> is</u><u> </u><u>4</u><u>t</u><u>h</u><u> </u><u>option</u><u> </u><u>.</u>

<em>I </em><em>hope</em><em> this</em><em> helps</em><em>. </em>

A rock band is playing a concert at Music Hall 49, which has 2,500 seats. If 80% of the tickets were sold before the night of th
nasty-shy [4]

First you must see how many seats were bought. To do this you must make a proportion

\frac{part}{whole} = \frac{part}{whole}

80 is a percent and percent's are always taken out of the 100. This means that one proportion will have 80 as the part and 100 as the whole

We want to know what 80% of 2,500 is in order to find how many seats were sold before the show. This means 2,500 is the whole and the unknown (let's make this x) is the part.

Here is your proportion:

\frac{x}{2,500} =\frac{80}{100}

Now you must cross multiply

x*100 = 80*2,500

100x = 200,000

To isolate x divide 100 to both sides

100x/100 = 200,000/100

x = 2,000

This means that before the night of the concert 2,000 seats were bought.

We are still not done with this problem because we want to know how many seats are left the night of the concert. To find this simply subtract 2,000 from the number of original seating (2,500)

2,500 - 2,000 = 500

On the night of the concert there were 500 seats left.

Hope this helped!

The sum of two numbers is eight one number is four less than the other find the numbers
mash [69]

Step-by-step explanation:

the numbers : x, y

x + y = 8

x = y - 4

we use the second equation in the first :

y - 4 + y = 8

2y - 4 = 8

2y = 12

y = 6

x = y - 4 = 6 - 4 = 2
