3 0
The number of multiples of 5 from 1 to 100 is:

1≤5n≤100

1/5≤n≤20, since n must be an integer

1≤n≤20

So the multiples of five number 20-1+1=20 elements, and the probability of choosing one of the multiples from the first 100 positive integers is:

P(5n)=20/100=1/5

Given: 315/1575. Write the prime fractorization of the numerator and the denominator, then write the fraction in lowest terms.
Ne4ueva [31]
The prime factorization of the numerator, 315, is 5 x 3 x 3 x 7. That of the denominator, 1575 is 5 x 5 x 3 x 3 x 7. To convert the fraction to its lowest form, cancel all the factors that appear to both the numerator and denominator. We will be left with 1/5.

Find the inverse of each of the given functions.
Leona [35]

Answer:

The inverse of the function is (3x+4)/2

Step-by-step explanation:

To find the inverse, exchange x and y and then solve for y

y = (2x-4) /3

Exchange x and y

x = (2y-4)/3

Solve for y

Multiply each side by 3

3x = (2y-4)/3 *3

3x =2y-4

Ad 4 to each side

3x+4 = 2y-4+4

(3x+4) =2y

Divide each side by 2

(3x+4)/2 =2y/2

(3x+4)/2 = y

The inverse of the function is (3x+4)/2

Refer to your math writing journal file named "Lines and Angles." What real-world examples did you describe for the three ways i
Sav [38]

Answer:

  1. Railway lines are example of parallel lines
  2. The floor and the walls of a room are example of perpendicular lines
  3. Two roads crossing at a signal can be termed as example of intersecting lines

Step-by-step explanation:

The lines can be related in following three ways

  1. Lines can be parallel
  2. Lines can be perpendicular
  3. Lines can be intersecting at an angle other than 90.

Now three real life examples of above three scenarios are described below:

  1. Railway lines are example of parallel lines
  2. The floor and the walls of a room are example of perpendicular lines
  3. Two roads crossing at a signal can be termed as example of intersecting lines

What is the answer 9c-5=13?
riadik2000 [5.3K]
C is 2 because you have to move the 5 so you add 5 to 13 which is 18 then divide both sides by 9 so it's 2
