Answer:
The price after a 30% discount would be 0.3p and the price after a 70% discount would be 0.7p.
Step-by-step explanation:
When you turn the percentages into decimals, 30% will be changed into 0.3, and when you change 70% into a decimal, it would be 0.7 (Move the decimal at the end two spaces over to the right like this: 70.% -> 7.0 -> 0.7)
Answer:
The area should be "210 cm to the second power"
Use copy dot flip to solve.
= 3 5/7 / 2/1
= 26/7 * 1/2 (Turned into improper fraction)
= 26/14 (Improper Fraction Answer)
= 1 12/14 (Mixed Number Answer Simplified)
= 1 6/7 (Final Answer Simplified)
Hope This Helped! Good Luck!
Answer:
0.025
Step-by-step explanation:
Hello!
Given that the classes are uniformly distributed between 45.0 and 55.0 minutes, the propability distribution will be:

Now, we are looking for a probability P(51.5<x<51.75) which can be computed as:

Therefore:
P(51.5<x<51.75) = 0.025
or
P(51.5<x<51.75) = 2.5%
<em><u>I strongly believe that the answer for both questions have the same answer, I believe this because there is no additional info for a given class or selecting a class. I think both probabilities are the same.</u></em>
