Answer:
y=3/4x-4
Step-by-step explanation:
the y intercept is -4 and then you plug in the slope
Solution:
<u>A few definitions...</u>
- Rational number - Any integer, fraction, terminating decimal, or repeating decimal is classified as a rational number
- Irrational number - All the real numbers which are not rational numbers.
<u>Option A - Rational or Irrational?</u>
Since both are known as fractions, they are rational numbers.
<u>Option B - Rational or Irrational?</u>
√2 is classified as an Irrational number because if it is simplified, it does not result in any integer, fraction, terminating decimal, or repeating decimal.
<u>Option C - Rational or Irrational?</u>
- 1/√4 + 7/2
- => 1/2 + 7/2
- => 8/2 = 4
Since this is an integer, this is rational.
<u>Option D - Rational or Irrational?</u>
- √9 + √4
- => √3 x 3 + √2 x 2
- => 3 + 2 = 5
Since this is an integer, this is rational.
In conclusion...
Option B is correct.
<h2>
Hello!</h2>
The answer is: George made his first mistake in Step 1.
<h2>
Why?</h2>
Getting a result of 26 cars needed means that he didn't take in consideration the next month in the mean calculation.
We have information of the number of sold cars of the first seven months, but if he wants to calculate the number of cards he needs to have a mean of 24 sold cards next months, he should take in consideration an extra month (the eighth month).
Checking the mistake:
So, it proves that he made a mistake by multiplying it into 7 and instead into 8
The correct answer would be:
He needed to include the eighth month in order to calculate how many cars he should sell next months in order to have a mean of 24 cars.
Have a nice day!
