It is given in the question that
M is the MIDPOINT OF FG.
Since M is the midpoint of FG, therefore GM is half of FG. That is
Therefore
And FM is 13 too .
Answer:
15:25
Step-by-step explanation:
Part A)
His sample only involves days during the summer (if Devin is in the northern hemisphere), which would mean that the high temperatures he'll record are likely to be higher than the average. Therefore, the sample mean he computes does not represent the average high temperature for the whole year.
----------------------------------------
Part B)
To correct his mistake, he needs to sample every day of the year. Or he could sample a few days of each month (say the first ten days of each month). That way the entire year is better represented. The other seasons of spring, fall and winter are included now.
If 140 people were surveyed, from the given table, the number of people that preferred crab is; 42
<h3>How to work with percentages?</h3>
We are given;
Total sample size; n = 140
Now, from the table we see the percentages that preffered each seafood.
Percentage that preferred Shrimp = 24%
Percentage that preferred Crab = 30%
Percentage that preferred Fish = 36%
Percentage that preferred Neither = 10%
Thus;
Number that preferred Crab = 30% * 140
Number that preferred Crab = 42 people
