Step-by-step explanation:
<u>Probability</u>
A standard deck of 52 playing cards has 4 aces.
The probability of getting one of those aces is
![\displaystyle \frac{4}{52}=\frac{1}{13}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B4%7D%7B52%7D%3D%5Cfrac%7B1%7D%7B13%7D)
Now we got an ace, there are 3 more aces out of 51 cards.
The probability of getting one of those aces is
![\displaystyle \frac{3}{51}=\frac{1}{17}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B3%7D%7B51%7D%3D%5Cfrac%7B1%7D%7B17%7D)
Now we have 2 aces out of 50 cards.
The probability of getting one of those aces is
![\displaystyle \frac{2}{50}=\frac{1}{25}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B2%7D%7B50%7D%3D%5Cfrac%7B1%7D%7B25%7D)
Finally, the probability of getting the remaining ace out of the 49 cards is:
![\displaystyle \frac{1}{49}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B1%7D%7B49%7D)
The probability of getting the four consecutive aces is the product of the above-calculated probabilities:
![\displaystyle P= \frac{1}{13}\cdot\frac{1}{17}\cdot\frac{1}{27}\cdot\frac{1}{49}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%3D%20%5Cfrac%7B1%7D%7B13%7D%5Ccdot%5Cfrac%7B1%7D%7B17%7D%5Ccdot%5Cfrac%7B1%7D%7B27%7D%5Ccdot%5Cfrac%7B1%7D%7B49%7D)
![\displaystyle P= \frac{1}{270,725}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%3D%20%5Cfrac%7B1%7D%7B270%2C725%7D)
P=0.0000037
P=0.00037%
Answer:
a) 120 words per minute
b) 130 words per minute
Step-by-step explanation:
A unit rate (also called a single-unit rate) is a type of ratio that compares 1 unit of one quantity to a different number of units of a another different quantity. When expressing in unit rate, the second quantity is in one unit.
a) Jasmine can read 120 words per minute
Jasmine reading unit rate = total number of words read / time taken
Jasmine reading unit rate = 120 words / 1 minute = 120 words per minute
b) It takes Scott one minute to read 130 words
Scott reading unit rate = total number of words read / time taken
Scott reading unit rate = 130 words / 1 minute = 130 words per minute

Answer:
Dennis paid $82 and Connie paid $46.
Step-by-step explanation:
We can set up an equation by putting in variables, c representing how much Connie paid. Since we know that Dennis paid $36 more, we will also factor that in the equation.
c + c + 36 = 128
Where c + 36 represents the amount Dennis paid, and 128 represents the total amount paid as given in the question. We can start by adding like terms. 2c + 36 = 128
Now, we can subtract 36 from each side,
2c + 36 - 36 = 128 - 36
2c = 92
Divide each side by two,
2c/2 = 92/2
c = 46
Now, to make sure this is correct, let's substitute our c for 46 in our equation:
46 + 46 + 36 = 128
92 + 36 = 128
128 = 128
Therefore, our equation is correct, and Dennis paid $82 while Connie paid $46.
