If two dice are rolled one time, find the probability of getting: a sum grater than 10\

1 answer:

4 0

If two dices are rolled once, you would have a total number of 6*6=36 possibilities.
To get a sum greater than 10:
A) one of your dices could be showing a 5, the other a 6. That’s two possibilities. Dice A being the 5 or dice B being the 5.
B) both of your dices could be showing 6s.
That’s one possibility.
So your overall possibility to get a sum greater than 10 is (1+2)/36 3/36=1/12
One twelfth.

Charlie runs a book rental business. He currently charges $3 per book and rents out an average of 38 books a day.

Answer:

b(x) = (3+0.5x) (38-4x)

Step-by-step explanation:

Let the generated revenue per day be b(x)

Let x be the number for every 50cents($0.5) price increase

Formula to be used to generate the revenue generated is expressed using the formula:

b(x) = Price × Quantity

Next is to derive the price and quantity function in terms of x.

For the price:

If he currently charges $3 per book

Let derive the price function for the model and x number of price increase for every 50 cents, then

Price = ($0.5 of x)+$3

Price = $3+$0.5x

Price = $(3+0.5x)

For the quantity:

Number of books rent out per day = 38

If for every 50cents increase in rental price x, the average business can expect to lose 4 rentals a day, then the total lost per quantity = 4x

Quantity per time = Number of books rent out daily - loss on each book

Quantity = $(38-4x)

Next is to substitute the price and quantity function into the revenue formula above:

Revenue = Price × Quantity

Revenue = (3+0.5x)(38-4x)

Hence the equation that models this scenario, where b(x) is the revenue generated and x is the number of 50 price increases is b(x) = (3+0.5x)(38-4x)

What’s the average for1/2,1/3 and1/6

Ugo [173]

1/2+1/3+1/6=3/6+2/6+1/6=6/6=1
By putting them all at the same denominator, you can add them all together.
then you have to divide it by 3 for the three.
1/3 is the average.

Amazon.com reported that 78 percent of a sample of 2,890 readers gave J. K. Rowling's 2007 release, Harry Potter and the Dealthy

lina2011 [118]

Let's differentiate the terms statistic and parameter. Statistic is a branch of mathematics that involves the treatment of various data through collection, preparation, analysis and interpretation. A parameter is a unit of measure which is an element of the system.

Since 78% is the percentage of the whole data, this is a statistic. A parameter, for instance, is the 2,890 readers :)

The answer is A.

I hope you clearly understood my explanation :)
