Which pair of radicals is a pair of like radicals?
(See image) thanks!

Answers

The pair of radicals that is a like pair is $7√(3)$ and $9 √(3)$

Option C is correct

For two radicals to be similar, they must contain the same number in the root operator.

Two like radicals are in the form:

$a√(b)$ and $c √(b)$

Since $a√(b)$ and $c √(b)$ are like terms, arithmetic operations such as addition, subtraction, multiplication, and division can be carried out on them

Considering the options given, only $7√(3)$ and $9 √(3)$ are in the form $a√(b)$ and $c √(b)$ because they have equal value inside the root operator.

Therefore, the pair of radicals that is a like pair is $7√(3)$ and $9 √(3)$

there are 4 single digit whole numbers represented by A, B, C, D. They are all different numbers.

when you multiply ABCD with D, you get DCBA

solve for the values of A,B,C, and D

(note: if A=2,B=3,C=4,D=5 then ABCD=2,345, but that is not the solution)

Show all work and do not copy

Answers

To start, ABCD(D)=DCBA means that D×A=D because they're all single digit numbers and since nothing carries over to make DCBA a 5 digit number A must be 1. If A is 1 for ABCD(D)=DCBA that would mean D^2 is a number ending in 1 so the only possibility for D is 9. Since D is 9, D×B has to be less than 10 because we know nothing carries over to the D×A (9×1) so B has to be 0. So far we have 10*9(9)=9*01 and since D×D (9×9) is 81 we need a number divisible by 9 that ends with 2 to add to the 8 digit which the only possibility is 72 from 8×9. SO A=1, B=0, C=8, D=9

A company that translates books between various languages is currently testing a computer-based translation service. The founder of the company expects the computer program to make some errors, but then so do human translators. The computer error rate is supposed to be an average of 2 per 500 words of translation. Suppose the company founder randomly selects a 3,000-word passage. Assume that the Poisson distribution applies and that the computer error rate is actually 2 errors per 500 words. Complete parts a through c.a. Determine the probability that no errors will be found.
The probability is ___. Round to four decimal places as needed.)

b. Calculate the probability that more than 30 errors will be found.
The probability is ___. (Round to four decimal places as needed.)

c. Find the probability that fewer than 15 errors will be found.
The probability is ___. (Round to four decimal places as needed.)

Answers

The probability that noerrors will be found is 0.

The probability of finding more than 30 errors is 0.0001.

The probability of finding fewer than 15 errors is 0.9452.

What is probability?

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

The number of errors in a 3,000-word passage follows a Poisson distribution with a mean of 12 errors.

i.e

Since 3,000 is six times 500.

The probability that no errors will be found.

P(X = 0) = $e^(-12)$ x $12^0$ / 0!

= 0.000006

Rounded to four decimal places.

= 0.0000.

The probability of finding more than 30 errors.

P(X > 30) = 1 - P(X ≤ 30)

We can use a Poisson table.

P(X ≤ 30) = 0.9999.

P(X > 30) = 1 - 0.9999

= 0.0001

Rounded to four decimal places.

= 0.0001.

The probability of finding fewer than 15 errors.

P(X < 15) = P(X <= 14)

= ∑(k=0 to 14) $e^(-12)$ x $12^k$ / k!

From the Poissontable.

P(X ≤ 14) = 0.9452

P(X < 15) = P(X ≤ 14)

= 0.9452

Rounded to four decimal places.

= 0.9452.

Thus,

The probability that no errors will be found is 0.

The probability of finding more than 30 errors is 0.0001.

The probability of finding fewer than 15 errors is 0.9452.

Kevin is going to purchase sod for his backyard (see diagram below). How many square feet of sod will Kevin need?

Answers

Answer:

450 square feet

Step-by-step explanation:

Think of the shape as a complete rectangular

The area of the rectangular shape would be 25×30 = 750 square feet

Now find the area of the missing space and subtract it from 750

it would be 15×20 = 300 square feet

750 - 300 = 450 square feet
