Okay so you start with 1/3. Fractions are just a fancy way of saying (in this case) 1 divided by 3. And if you do that you'll get .3333. After that to make it a percent you just move the decimal spot in front of the 3 over two places, getting 33.33%. With mixed numbers it's just one more step. So in this case 2 1/5 you would have to make it a normal fraction first so I got 11/5ths and here's how I got it. 2 1/5. Multiply the denominator (5) with 2. You get 10. Then add the numerator (1) to get 11. Tack on the 5 and you get 11/5. To make this a percent just do the same thing as the normal fractions... 11 divided by 5 to get 2.2. Move the decimal two places to the right to get 220%. Try the rest on your own and if you get confused ask... :)

professor190 [17]

A Comment "If i know the measures of angles C and B, I can find the measures of A and D" is TRUE

Explanation :

If we know angles C and B we can find angles A and D as,

As from figure we know

                     A+B = 180°

∴                     A = 180° - B                           ... we know B so we get A

Also,

                   B+C+D = 180°                          ... as BCD is a triangle

∴                           D = 180° - (B+C)              ... we know B and C so we get D

In how many ways you can put 20 books on 50 shelves so that there is not more than one book on a shelf?
elena-s [515]

Answer:

The other answer I saw is the same way that I used to explain in my class as well. But, there's an alternative way to reach the answer as well

First thing that we should know is that if there are 'n' units kept in a row, then there are 'n+1' gaps generated by them. So, what we should understand is that when there is no item there is 1 gap, when there is one item there are 2 gaps, and so on.

Let us use that concept here, with a small variation: the 5 shelves are 5 initial gaps. The first book has 5 choices (5 initial gaps) to go to. Once we have placed this book, there are now 6 gaps on which the 2nd book can be placed. After the 2nd book is placed, there are 7 gaps in which 3rd book can be placed, and so on.

So, the total arrangements will be = 5*6*7*...24 [as there are 20 books] = 24P20

Use the data in the following​ table, which lists​ drive-thru order accuracy at popular fast food chains. Assume that orders are
Sergeu [11.5K]

Probability of getting an order from Restaurant A or an order that is accurate is 1.21,

The events are not disjoint events.

<h3>What is the probability?</h3>

Probability is used to calculate the odds that a random event would occur. The odds that the random event happens lie between 0 and 1.  

Total number of accurate orders = 332 + 277 + 244 +  150 = 1,003

Total number of orders = 31 + 51 + 30 + 10 + 1003 = 1,125

Total number of orders from restaurant A = 332 + 31 = 363

Probability of getting an order from Restaurant A = total number of orders from restaurant A / total number of orders

363 / 1125 = 0.32

Probability that the order is accurate = number of accurate orders / total number of orders

1003 / 1125 = 0.89

Probability of getting an order from Restaurant A or an order that is accurate = 0.32 + 0.89 = 1.21

Disjoint events are events that are mutually exclusive. If one event happens, the other event cannot happen
