Here are some probability scenarios.

- Flipping a coin and seeing if it is heads or tails.

- Thinking to yourself: "Is it going to rain or hail?"

- Spinning a spinner and seeing what color it lands on.

- Probability in winning the lottery.

- Having 5 pairs of black shoes and one pair of yellow shoes.

The probability of picking the yellow shoe is 1/5.

There are lots of more examples out there!

There is a total of $39.55. There are 3 times as many dimes as nickels, how many of each coin type was collected ?

Number of dimes collected is 339 and number of nickels collected is 113

Solution:

Given that There is a total of $39.55

There are 3 times as many dimes as nickels

To find: Number of dimes and nickels collected

Let "d" be the number of dimes collected

Let "n" be the number of nickels collected

We know that,

1 dime = $ 0.10

1 nickel = $ 0.05

From given information,

There are 3 times as many dimes as nickels

So, we get

Number of dimes = 3(number of nickels)

d = 3n

Given that there is total of $ 39.55

number of dimes collected x value of 1 dime + number of nickels collected x value of 1 nickel = $ 39.55

$3n \times 0.10 + n \times 0.05 = 39.55\\\\0.3n + 0.05n = 39.55\\\\0.35n = 39.55\\\\n = \frac{39.55}{0.35}\\\\n = 113$

Substitute n = 113 in d = 3n

$d = 3(113) = 339$

Summarizing the results:

number of dimes collected = 339

number of nickels collected = 113

-2 x 4^5 + 18 x 4^5 = ? The answer must be in form of a^b. Please explain step by step.

zalisa [80]

Answer:

17*2^11

Step-by-step explanation:

Lets start by remembering two property of power.

$x^{m} * x^{n}= x^{n+m}$

$(x^{m})^{n}= x^{m*n}$

That is important to remember since 4= 2^2. Hence, the given problem can be written as the following

$-2*(2^{2} )^{5}+9*2^{2}*(2^{2} )^{5} \\-2*2^{10}+9*2^{2}*2^{10}\\ -2^{11}+9*2^{12}\\ -2^{11}(-1+9*2)=-2^{11} (17)$
