Hi there!

Well to solve this problem we obviously need to multiply 3/8 by 4/9,

3/8*4/9=12/72

3 groups of 4/9 bascially means 3*4/9

3*4/9=12/9

Divide by 8,

12/9/8=12/9*1/8=12/72

Thus, As I divided into 3 groups of 4/9 which is 3/9*4/8

Hoped I helped. :)

Dilate the figure by the scale factor. Then enter the new coordinates. K=2
Artyom0805 [142]

Answer:

A = (-6, 4)

B = (2,2)

C =  (-2, 2)

Step-by-step explanation:

If a coordinate (x, y) is dilated by a factor of k, the resulting coordinate will be expressed as (kx, ky). Note that each coordinate is multiplied by the scale factor

Given the coordinates (-3,2),(1,1)(-1,-1), if they are dilated by a factor of 2, the resulting coordinate will be;

A = (2(-3), 2(2)) = (-6, 4)

B = (2(1),2(1)) =(2,2)

C = (2(-1), 2(-1)) = (-2, 2)

On a multiple choice test with 15 ​questions, each question has four possible​ answers, one of which is correct. For students wh
Aleks [24]

Answer:

The variance for the number of correct answers is 2.8 questions

Step-by-step explanation:

The number of correct answers follows binomial distribution, in which we have:

  • n identical and independents events: the 15 questions
  • two possibles results that we call success and fail: The answer is correct and the answer is incorrect
  • probability p of success and 1-p of fail. Probability 1/4 of get the answer correct and probability of 3/4 of get the answer incorrect. This probabilities are calculated on that way because every question have 4 possible answers and one of which is correct.

So, the variance for a variable x that follows a Binomial distributions is:

V(x)=n*p*(1-p)

Then, the variance for the number of correct answers is:

V(x)=15*(1/4)*(3/4) = 2.8125 ≈ 2.8

Because n is equal to 15, p is equal to 1/4 and (1-p) is equal to 3/4.

given the equation 5y-3x=15 how would you determine another equation which would have: no solution, one solution, and infinitely
victus00 [196]
First, I would convert the equation to slope intercept form. 

That would be:  y = (3/5)x + 3  , now it will be easier to create the needed equations.

For no solution, keep the slope the same and change the y-intercept.
You could have: y = (3/5)x + 9

For one solution, all we have to do is change the slope.
You could have: y = (4/5)x + 3

For an infinite number of solutions, just multiply the entire equation by any number. Let's use the number 2.
2y = (6/5)x + 6
