You randomly select a card from a 52-card deck. Find the probability of selecting a 7 or an Ace.​

Answers

Answer 1

Answer:

15.38%

Step-by-step explanation:

There are 4 7's in a deck of 52 cards.

There are 4 Aces in a deck of 52 cards.

4+4 = 8

8/52, or 15.38%

Answer 2
Answer:  2/13

=================================================

Explanation:

There are four cards labeled "7", and four cards that are aces. We have 4+4 = 8 cards that we want to find. This is out of 52 total.

The probability we're after is 8/52 = (4*2)/(4*13) = 2/13

2/13 = 0.1538 = 15.38% approximately

Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots. Which is the total weight of the lettuce and carrots in ounces?
A. 10 ounces
B. 12 ounces
C. 40 ounces
D. 72 ounces

Answers

The total weight of the lettuce and carrots in ounces is 40 ounces if Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots option (D) is correct.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have:

Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots.

As we know:

1 pounds = 16 ounces

Amount of lettuce = 8 ounce


Amount of carrots = 2 pounds = 2×16 = 32 ounces

Total weight of the lettuce and carrots in ounces =  8 + 32 = 40 ounces

Thus. the total weight of the lettuce and carrots in ounces is 40 ounces if Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots option (D) is correct.

The statement describes the behavior of the function around the vertical asymptotes is B.

We have given the graph,

We have to determine which statement describes the behavior of the function around the vertical asymptotes.

What is the vertical asymptotes?

A vertical asymptote is a vertical line that guides the graph of the function but is not part of it. It can never be crossed by the graph because it occurs at the x-value that is not in the domain of the function. A function may have more than one vertical asymptote.

If you look from both sides of the graphs you can see it adds upward.

5. PA license plates have 3 letters followed by 4 numbers.
a. If the same letter or number can be repeated, how many can be made?
b. If the same letter CANNOT be repeated, how many can be made?

Answers

Answer:

A. 175,760,000

B. 156,000,000

Step-by-step explanation:

For part A:

There are 26 letters in the alphabet.  Therefore, if there are 3 spots to use 26 letters, that is represented as [tex]26^3[/tex].  As for numbers, there are 10 digits from 0-9.  So if there are 4 spots for numbers, the total possible number of sequences is [tex]10^4[/tex].  So you simply multiply [tex]26^3[/tex] and [tex]10^4[/tex] to get 175,760,000 possible combinations.

For part B:

If the same letter can't be repeated, instead of using an exponent, we have to use a factorial, but only for the 3 digits required in the license plate.  These are called permutations and can be expressed as [tex]_2_6P_3[/tex], which is the same as saying 26 x 25 x 24.  Since there is no change to number of numbers, that remains the same.

[tex]_2_6P_3 * 10^4 =26*25*24*10^4=156,000,000[/tex]

The answer is 8
Explanation- 9x4= 36 and 288 divided by 36 equal 8

Answer:

8 feet

Step-by-step explanation:

Volume = length * width * height

Substitute the values.

288 = 9 * 4 * height

Divide both sides by 36

height = 288/36

height = 8 feet

Paul can build a desk in 12
hours. Shawn can build the
same desk in 8 hours. How
long would it take them to
build it together?
[?] minutes

Answers

Answer:

288

Step-by-step explanation:

First, find how much of the desk each person can finish in 1 hour. Paul can finish 1/12 because he finishes the whole thing in 12 hours and Shawn can finish 1/8 because he finishes the whole thing in 8 hours.

Then find a common denominator and add those together to find how much they could do together in 1 hour.

2/24 + 3/24 = 5/24 So they can finish 5/24 of the desk in 1 hour if they work together.

So to finish 24/24 of the desk, they'll need to do 4 hours (20/24 of the desk) and 48 minutes (4/24 of the desk)

It asked for the number of minutes, so multiply 4 by 60 and add 48 to find the total number of minutes. 4*60 = 240 and 240 + 48 = 288

So it will take them 288 minutes to build the desk together.

Answers

9514 1404 393

Answer:

  b.  10.2 yards

Step-by-step explanation:

The quadratic formula tells you the solutions to ...

  ax² +bx +c = 0

are given by ...

  [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Here, the quadratic equation we have is ...

  h² +5h -155 = 0

So the solutions given by the quadratic formula are ...

  [tex]h=\dfrac{-5\pm\sqrt{5^2-4(1)(-155)}}{2(1)}=\dfrac{-5\pm\sqrt{645}}{2}=\{-15.2,10.2\}[/tex]

The negative solution is not applicable in this situation, so the height that gives the desired area is 10.2 yards.
