Step-by-step explanation:

Answer: 3/10

Work (Easy Method): So the easy method is to count how many spaces are there, and since there are 10, you choose the 3/10

Work (Harder Method): You count the White spaces in both, and put it over the total spaces, So, since there's 4 white spaces in Tracy, and 10 total spaces, you do 4/10, and same goes with Carol. So, you just subtract 7/10 by 4/10, and you get 3/10

a postman brought n letters to a house with two letter-boxes. since the two boxes were empty, he puts 1 mail in each of the two mail boxes. then he chooses one of boxes with probability proportional to number of letters present in that box, and puts the 3rd letter in it. he does this for all subsequent letters. what is the expected number of letters in the box with lower letters?

Answers

Expected number of letters in small box is n/4.

I referred the solution for the above problem. Suppose I have a stack of 2 black cards and one red card. Initially I put red between 2 black cards. Now I add black cards randomly between any two cards (so, initially it is either above or below red). Note that the probability that I add the card above the red card, when x-1 is the number of cards above red and y-1 is the number of cards below red is x/(x+y). Let the problem be: if red card is dividing the black cards into two sets, what is the expected number of black cards in the smaller section. So, we see that the two problems are equivalent.

Now this way, we are getting all possible combinations in which one red and n black cards can be mixed, we see that the probability that the red card is at height h is independent of h. So, the probability that the smallest box contains n/2 letter or 1 letter (or any number of letters between 1 and n/2) are all same. So, expected number of letters in the smaller box is asymptotically n/4.

The formula for any geometric sequence is an = a1 · rn - 1 , where an represents the value of the n th term, a1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...? an = 4 · ( ) n - 1 an = 2 · 4 n - 1 an = 32 · 2 n - 1 an = 4 · 2 n - 1

Answers

Answer:

an = 4 · 2^(n - 1)

Step-by-step explanation:

Given:

an = a1 · r^(n - 1)

Where,

an = value of the n th term

a1 = value of the first term

r = common ratio

n = the term number.

What is the formula for the geometric sequence 4, 8, 16, 32, ...?

a1 = 4

r = 8/4

= 2

n = n(not given)

Substitute the values of a1 and r into the formula

a1 = 4

r = 2

an = a1 · r^(n - 1)

an = 4 * 2^(n - 1)

The correct answer is:

an = 4 · 2^(n - 1)

A number consists of two digits. The sum of its digits is 16. If 28 is subtracted from the number, the digits interchange their place. Find the number. |.Give the answer only ​

Answers

Answer:

The number is 97

Step-by-step explanation:

Note: The difference should read 18 not 28, it must be a typo. In general such difference must be a multiple of 9.  

Let the digits are x and y.

If the first digit is x and the second digit is y, then the number is 10x + y.

According to the question we have:

x + y = 1610x + y - 18 = 10y + x ⇒ 9x - 9y = 18  ⇒ x - y = 2

Add up the equations:

x + y + x - y = 16 + 22x = 18x = 9

Find y:

9 + y = 16y = 7

The number is 97.

Your answer is 5/8

Step-by-step explanation:

I used Microsoft Math

5/8 divided by 1/3 in simplest form

Answers

Answer: 1-7/8.

Step-by-step explanation;

Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:  5/8 / 1/3 = 5/8 * 3/1.

Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:  15/8.

15 ÷ 8 = 1R7, therefore:  1-7/8.

The required, 15/8, is the simplest form. It cannot be further reduced since the numerator (15) and the denominator (8) have no common factors other than 1.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator. Let's calculate the division:

(5/8) ÷ (1/3)

Find the reciprocal of the second fraction:

Reciprocal of (1/3) = 3/1 = 3

Now, multiply the first fraction by the reciprocal of the second fraction:

(5/8) * 3 = (5 * 3) / 8 = 15 / 8

So, the answer to 5/8 divided by 1/3 in simplest form is 15/8.
