Answer:

Explained below.

Step-by-step explanation:

A compound event is an event in which has possible outcomes more than one.

To determine the probability of compound events on has to compute the sum of the probabilities of all the individual events and, if required, remove any coinciding probabilities.

Examples of compound events are:

The events of roll a five using a 6-sided die .

The number of favorable outcome is rolling a 5, is 1.

The total number of outcomes of rolling a die is 6.

Then the probability of rolling a 5 is 1/6.

The events of pulling a heart out of a standard deck of cards

The number of favorable outcome of pulling a heart is 13.

The total number of outcomes is 52.

The probability of pulling a heart from a standard deck is 13/52 or 1/4.

Thus, the procedure is to compute the sum of the probabilities of all the individual events and, if required, remove any coinciding probabilities.

Joy recorded the distances she walked each day for five days. How far did she walk in 5 days?

laila [671]

Answer: She walk $2\frac{1}{6}\ miles$ in 5 days.

Step-by-step explanation:

Since we have given that from the graph:

Distance of $\frac{1}{3}$ for 3 days.

Distance of $\frac{1}{2}$ for 1 day.

Distance of $\frac{2}{3}$ for 1 day.

So, Total distance she covered by walk in 5 days is given by

$\frac{1}{3}\times 3+\frac{1}{2}+\frac{2}{3}\\\\=1+\frac{1}{2}+\frac{2}{3}\\\\=\frac{6+3+4}{6}\\\\=\frac{13}{6}\\\\=2\frac{1}{6}\ miles$

Hence, She walk $2\frac{1}{6}\ miles$ in 5 days.

On december 1, jonas jewelry wholesale center started with an inventory of 1,000 watches. shipments of 168, 231, and 411 were se

denis-greek [22]

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

Total watches in an inventory = 1000

Number of shipments sent out = 168, 231, 411

So, Remaining inventory of watches would be :

$1000-(168+231+411)\\\\=1000-810\\\\=190$

New receipts = 21, 145 and 11

So, Number of watches on hand becomes :

$190+(21+145+11)\\\\=367$

Hence, Third option is correct.

PLZ HELP NO WRONG ANSWERS

Ray Of Light [21]

Answer :

to find area of the square = 6 to the power 2

to find the area of the rectangle = (5x + 12) * 5x

therefore,

square's area = 36

rectangle's area = 5x*5x + 12 * 5x

= 25x * 60x

Now we have to find the sum of both the areas,

so, 36 + 1500 = 1536

natulia [17]

Answer: 20 boxes of chocolates

Step-by-step explanation:

First find out the total number of chocolates he has:

= 25 boxes * 24 chocolates per box

= 600 pieces of chocolate

The number of boxes needed if the chocolates are packed 30 in a box is:

= Total number of chocolates / Number of chocolates per box
