The simplified version of the expression is this: 5(x² + 9) ÷ x.
Answer:could you maybe simplify the question
Step-by-step explanation:
Answer: The professor was not accurate with his hypothesis.
Null hypothesis: P1 = 12.5%, P2 = 42.5%, P3 = 45%
The alternate hypothesis: At least one proportion of the student will differ from the others.
Step-by-step explanation: To check if the professors hypothesis were inaccurate.
What percentage of student bought a hard copy of the book.
(25 ÷ 200) × 100 = 12.5%
What percentage of the student printed it from the web.
(85 ÷ 200) × 100 = 42.5%
What percentage of the students read it online.
(90 ÷ 200) × 100 = 45%
This means that the professor was not accurate with his hypothesis. Because the proportion of student in his hypothesis was not the same in the actual.
Therefore; the null hypothesis are
P1 = 12.5%, P2 = 42.5%, P3 = 45%
The alternative hypothesis will state that at least one of the proportion will be different from the others.
Answer:
I think 5 of the 15 deliveries are plants.
Step-by-step explanation:
I divided 6 by 18 to get 3.4 (I rounded up), which translates to 34%. 34% of 15 is 5.1, I rounded to get 5.
I checked my work by getting 34% of 18, which is 6.12 and would round to 6.
Here is your answer
Given
length of rectangle= 5 inch
its width= x inch
Perimeter= 2 (l+b)
= 2 (5+x)
= 10+2x inches
