Answer:
2 
pizzas
Step-by-step explanation:
The equation to this question can be written as 5/6 + 5/6 + 5/6 or 5/6 x 3.
To multiply 5/6 by 3, we can set it up as 
. Now to multiple, we just multiply straight across. We do 5 * 3 over 6 * 1 to get 15/6. Now, all we have to do is simplify the fraction. 6 goes into 15 two times, so we know they ate 2 pizzas. Now we are left with 3/6. 3/6 can be rewritten as . In total, they ate 2 pizzas.
Hope this helps!
Hi, The answer is 2x^2-8x+12, because when you subtract the polynomial with the answer you will get x^2-4
Answer

3)false
4)true
5)true
Step-by-step explanation:
5/8÷1/3=5/8×3/1
(multiply by reciprocal instead of dividing)
5/8×3/1=15/8=1.875
Considering the situation described, we have that:
- The appropriate null hypotheses is
.
- The appropriate alternative hypotheses is
.
<h3>What are the hypotheses tested?</h3>
At the null hypotheses, it is tested if the mean has not been reduced, that is, it still is of 5.2 hours, hence:
.
At the alternative hypothesis, it is tested if the mean has been reduced, that is, it is now of less than 5.2 hours, hence:
