Answer: Infinitely many solutions
The solutions are of the form (x,y) = (x,3x+5) for any real number x.
========================================================
Explanation:
Plug the first equation into the second. We'll replace y with 3x+5
12x-4y = -20
12x-4( y ) = -20
12x-4(3x+5) = -20 .... y replaced with 3x+5
12x-12x-20 = -20
0x-20 = -20
0-20 = -20
-20 = -20
We end up with a true equation no matter what x is.
Therefore, this system has <u>infinitely many solutions</u>.
Each solution is of the form (x,y) = (x,3x+5) because y = 3x+5.
There is an infinite number of any smaller figures inside of any figure. It's because we can always divide it "one more time", and then again and again and again...
Answer:
We accept the alternate hypothesis and conclude that mean SAT score for Stevens High graduates is not the same as the national average.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 510
Sample mean, = 502
Sample size, n = 60
Sample standard deviation, s = 30
Alpha, α = 0.05
First, we design the null and the alternate hypothesis
We use Two-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and fail to accept it.
We accept the alternate hypothesis and conclude that mean SAT score for Stevens High graduates is not the same as the national average.
Answer:
<u>The hamburger earns $ 1.50 for each hamburger he sells</u>
Correct statement and question:
The profit a hamburger vendor earned, in dollars, is proportional to the number of hamburgers sold. This equation represents the proportional relationship between the profit earned and number of hamburgers sold.
2p = 3H.
Enter the profit, in dollars, earned for each hamburger sold.
Source:
Previous question that can be found at brainly
Step-by-step explanation:
Let's find the value of p, profit earned when H = 1:
2p = 3H
2p = 3 * 1
2p = 3
p = 3/2
p = 1.5
<u>The hamburger earns $ 1.50 for each hamburger he sells</u>
