Answer:
2 bowls of soup
Step-by-step explanation:
<u>1. Make 1 1/4 an improper fraction</u>
1 1/4 = 5/4
<u>2. Then divide 5/4 by 5/8 (KCF - </u><u>Keep</u><u> the 5/4 - </u><u>Change</u><u> the division sign to multiplication - '</u><u>Flip' </u><u>5/8 to 8/5)</u>
5/4 x 8/5 = 40/20
<u>3. Simplify the fraction (divide the numerator and denominator by 20)</u>
40/20 = 2
<u>4. Final answer:</u>
2 (bowls of soup)
Answer: The sample mean
Step-by-step explanation:
The confidence interval is given by :-
Sample mean ± Margin of error
Given : The scores on a standardized test are normally distributed. If a random sample of standardized test scores is taken and the confidence interval is (497,537).
i.e. Sample mean - Margin of error = 497 ..(i)
Sample mean + Margin of error=537 ..(ii)
Adding (1) and (2), we get
2 (Sample mean) = 1034
⇒Sample mean = 517
Hence, the sample mean
Answer:
Step-by-step explanation:
If you start with a 52 card deck which includes 4 sevens and remove a seven and another card, then the (number of sevens in the deck) is 3 and the (number of cards) is 50. So, in that specific case, assuming that the cards are arranged in a uniform random order, the answer would be 3/50.
