Answer:
The lawn care is the most sucsessful.The most money is earned and the uh House shelter or whatever is in the middle and the dog thing is the least sucsesful with the money.
For the second,i dont get it.
The lawn care is wealthy BUT never judge a book by its cover so the lawn care (lc)may be dirty,smelly,uncivilized,or just no privacey.
Option D:
No, Claire should have gotten –2y = –8 instead of 2y = –8 in step 4.
Solution:
The system of equations are
4x – 2y = 4 – – – – (1)
3x + 3y = 21 – – – – (2)
Step 1: Multiply the equation (1) by 3 and equation (2) by 2
12x – 6y = 12
6x + 6y = 42
Step 2: Add the above equations.

⇒ 18x = 54
Step 3: Divide both sides of the equation by 18.
⇒ x = 3
Step 4: Substitute x = 3 in equation (1)
4(3) – 2y = 4
⇒ 12 – 2y = 4
Subtract 12 from both sides of the equation.
⇒ –2y = –8
Divide by –2 on both sides of the equation.
⇒ y = 4
Step 5: The solution is (3, 4).
But Claire's solution is (3, –4).
Claire's solution is not correct in step 4.
Option D is the correct answer.
No, Claire should have gotten –2y = –8 instead of 2y = –8 in step 4.
Answer:



Step-by-step explanation:
For this case we have a confidence interval given as a percent:

If we express this in terms of fraction we have this:

We know that the confidence interval for the true proportion is given by:

And thats equivalent to:

We can estimate the estimated proportion like this:

And the margin of error can be estimaed using the fact that the confidence interval is symmetrical

And then the confidence interval in the form desired is:

Answer:
5
+5
Step-by-step explanation:
The core uses the value of the Pythagorean theorem and special angles.
