1. Find the total number of class members
9 + 11 = 20
2. Find 9 as a percentage of 20
9 / 20 = 0.45
0.45 x 100 = 45%
<u>45% of the class are girls.</u>
Step 2: it should be P-2x, not +.
Hope this helped :)
Answer:
Step-by-step explanation:
Now,
if you add the tip after the sales tax,
you will have:
46.55*(6/100)=2.79
the meal cost now 46.55+2.79=49.34
we add tip
49.34*(18/100)=8.88
total cost 49.34+8.88=58.22
The answer is 39 because 6 times 5 is 30. 30 plus 9 is 39. :)
Answer:
95%
Step-by-step explanation:
The empirical rule states that if data follows normal distribution then the percentage of observations falls within one, two and three standard deviation around the mean are
i) 68% falls within one standard deviation
ii) 95% falls within two standard deviation
iii) 99.7% falls within three standard deviation.
Hence 95% of the observations will fall within two standard deviations around the mean if the data follows normal distribution.
