Answer:
16 questions answered correctly
Step-by-step explanation:
Since the student answered 80% of the questions correctly, we can find 80% of 20 to answer this question.
[] First we will convert the percent into a decimal format;
80% / 100 = 0.8
[] Then we will multiply this by 20 to find our answer;
20 * 0.8 = 16 questions answered correctly
Answer:
275 minutes 12 seconds
Step-by-step explanation:
Given that :
slowest running time per mile = 9 minutes and 14 seconds
fastest running time per mile = 7
minutes and 58 seconds.
To estimate the time taken to run 16 miles ;
Obtain the Average of the two run times :
(9 minute 14 seconds) + (7 minutes 58 seconds) = 17 minutes 12 second
Hence it takes an average of 17 minutes 12 seconds per mile
Time taken to run 16 miles :
((17 * 60) + 12) * 16 = 16512 seconds
16512 / 60 = 275 minutes 12 seconds
Tan 21 44 = h / 13428.7
h = 13428.7 * tan 21 44
Height = 5353 feet
Answer: 0.5
Step-by-step explanation:
Total slots= 38
Subtracting the slots numbered 0 and 00, total slots= 38-2= 36
So out of 36, half are even and half are odd..
So probability that ball lands in an even numbered slot= 18/36= 1/2= 0.5
