Jack uses a probability simulator to roll a six-sided number cube 100 times and to flip a coin 100 times. The results of the exp

eriment are shown below:
Number on the Cube Number of Times Rolled
1 16
2 14
3 5
4 17
5 21
6 27


Heads Tails
41 59


Using Jack's simulation, what is the probability of rolling a 6 on the number cube and the coin landing on heads?
fraction 1,107 over 10,000
fraction 1,593 over 10,000
fraction 27 over 100
fraction 41 over 100

<h2>Answer:</h2>

The probability of rolling a 6 on the number cube and the coin landing on heads is:

            fraction 1,107 over 10,000 i.e.  \dfrac{1107}{10000}      

<h2>Step-by-step explanation:</h2>

Let A denote the event of rolling a 6 on number cube.

and B denote the event of landing a head on a coin.

Clearly both the events A and B are independent.

Also, let P denote the probability of an event.

We are asked to find: P(A∩B)

We know that when two events A and B are independent.

Then,

P(A\bigcap B)=P(A)\times P(B)

Now, based on the two tables we have:

P(A)=\dfrac{27}{100}

( Since, 6 comes up on rolling a number cube 27 times out of a total of 100 times)

Also,

P(B)=\dfrac{41}{100}

( since head comes up 41 times out of a total of 100 times)

Hence, we get:

P(A\bigcap B)=\dfrac{27}{100}\times \dfrac{41}{100}

i.e.

P(A\bigcap B)=\dfrac{27\times 41}{100\times 100}

i.e.

P(A\bigcap B)=\dfrac{1107}{10000}

The experimental probability is the number of specific outcomes divided by the sample size...


P(6)=27/100  (27%)


P(H)=41/100  (41%)


Not sure, but if you meant rolling a 6 AND getting a head then:


P(6 AND H)=(27/100)(41/100)=1107/10000  (11.07%)

4(2p+3)=16<br> solve the equation
Natali5045456 [20]

Final Answer: p = \frac{1}{2}

Steps/Reasons/Explanation:

Question: Solve the equation 4(2p + 3) = 16.

<u>Step 1</u>: Divide both sides by 4.

2p + 3 = \frac{16}{4}

<u>Step 2</u>: Simplify \frac{16}{4} to 4.

2p + 3 = 4

<u>Step 3</u>: Subtract 3 from both sides.

2p = 4 - 3

<u>Step 4</u>: Simplify 4 - 3 to 1.

2p = 1

<u>Step 5</u>: Divide both sides by 2.

p = \frac{1}{2}

Step-by-step explanation:

For easier understanding and calculation; we created a table for solving this question.

Minimum Shipping Cost to Dallas is from Houston and they have 850 air conditioners, Dallas need 800, so ship all required 800 air conditioners from Houston itself

Minimum shipping cost of Atlanta is from Memphis and they have 350 air conditioners, but Atlanta need 700, so ship all the 350 air conditioners that Memphis have to Atlanta

Minimum shipping cost to Denver is from Phoenix and they have 800 air conditioners, but Denver need 250, so ship all the required 250 air conditioners to Denver itself.

Still Atlanta need 350 air conditioners more, the second minimum shopping cost to Atlanta is from Houston and they have 50 air conditioners left .

So, ship all the 50 air conditioners that Houston have to Atlanta

Also, sent the remaining 300 air conditioners that Atlanta need from Phoenix

Semenov [28]

If a advertised sofa is $200 but the more costly sofa is $375, the average cost of such a sofa will be $200 is $243.75.

<h3>Define the term average of the number?</h3>
  • An averaging is a single number calculated as the average of a set of numbers,.
  • Typically calculated as the sum of a numbers divided by the total number of numbers in the set (the arithmetic mean).

You're planning to purchase a sofa from a furniture store that is having a sale on them.

Let x represent the sofa's price.

Advertised sofa's cost = $200

Expensive sofa's cost = $375

The advertisers are aware that when customers arrive at the store, one out of three switch to an expensive sofa that the one shown in the sale advertisement.

Average cost = 375 x 1/4 + 200 x 3/4

E(x) = 375 x 1/4 + 200 x 3/4

E(x) = 93.75 + 150

E(x) = 243.75

Thus, if a advertised sofa is $200 but the more costly sofa is $375, the average cost of such a sofa will be $200 is $243.75.
