Mr. Lance keeps a jar of candy on his desk for students to pick from when they do well on a test. The jar contains 5 Snickers, 2 Butterfingers, 4 Almond Joys and 3 Milky Ways. If two students get to pick candy from the jar, what is the probability that the first student picks a Snickers and then the second student also picks a Snickers?

Answers

Answer: $(10)/(91)$

Step-by-step explanation:

Given : The jar contains 5 Snickers, 2 Butterfingers, 4 Almond Joys and 3 Milky Ways.

Total candies in the jar = $5+2+4+3=14$

Provability that firsts student select snickers = $(5)/(14)$

Now total candies in jar = 14-1=13

Total snickers remained =5-1=4

Probability that the second student also select snickers= $(4)/(13)$

Then, the probability that the first student picks a Snickers and then the second student also picks a Snickers :-

$(5)/(14)*(4)/(13)=(20)/(182)=(10)/(91)$

Hence, the required probability = $(10)/(91)$

7. Use the Division Property of Equality to complete the following statement. (1 point)If 5x = 2y, then x = ?
OO
UOD
W
O2y - 5

Please help

Answers

For this case we have the following equation:

$5x = 2y$

To find the value of "x", we use the division equality property, that is, we divide by 5 on both sides of the equation:

$\frac {5x} {5} = \frac {2y} {5}\nx = \frac {2} {5} y$

Thus, using the mentioned property we have to: $x = \frac {2} {5}y$

Answer:

$x = \frac {2} {5} y$

A hardware store pays $3,500 for 42 lawnmowers. Then the store sells the lawnmowers for $99 each. How much profit does the store make from the lawnmower sales?I think the equation is 99×42, and then you subtract that number from $3,500.
Please tell me if i am right, if i am wrong, please tell me how to do it.

Answers

The total profit of the store by selling the lawnmower is $658.

Total Cost

The total cost of a number of items of similar type is the product of the price of each unit and the number of units bought.

$\rm{Total\ Cost= Price/unit * Number\ of\ units$

Given to us

A hardware store pays $3,500 for 42 lawnmowers.
the store sells the lawnmowers for $99 each.

Total cost of all the lawnmowers

The total cost of all the lawnmowers is given to us as $3,500 also the number of lawnmowers are given 42.

Total earnings through the lawnmowers

As the store sells each lawnmower for $99, the total earnings through the lawnmowers to the store,

$\begin{aligned}Total\ earning\ of\ lawnmowers&= Selling\ Price/unit * Number\ of\ units\ sold\n&= \$99* 42\n& = \$4,158 \end{aligned}$

Total profit of the store

The total profit of the store

= Total earning through the sale of lawnmowers - Total cost of lawnmowers

$= \$4,158 - \$3,500\n= \$658$

Hence, the total profit of the store by selling the lawnmower is $658.
