Answers
4) We can round 81.25% to 80 and 21 shots to 20. 20 x 0.8 = 16.
The answer is A. about 16
5) Your answer is correct. 48% is almost half; half of $20 is $10, so the answer is D.
6) Your answer is correct, C. 15% x 100 = $15
7) The proportion 50/100 = x/70 can help solve this. The answer will be 35.
8) We simply do:
15/50 x 100 = 3/10 x 100 = 30%
9) You are correct, C. 0.3 x 60 = 18

Determine the mean age and standard deviation, to the nearest tenth, of the people who remain at the party.
A. The mean age of the remaining people at the party is a0
B. The standard deviation is:
Answers
Ten People
5 people = 30 years old
3 people = 32 years old
1 person = 31 years old
1 person = 65 years old
We need to arrange the ages in order from least to greatest.
30, 30, 30, 30, 30, 31, 32, 32, 32, 65
65 is the outlier.
A.) mean age without the outlier. count of the numbers : 9
5 x 30 = 150
1 x 31 = 31
3 x 32 = 96
total age 277
÷ # of pax 9
mean 30.77 round to the nearest tenth 30.80
b.) Standard deviation:
We need to calculate variance first:
5 pax : 30 - 30.80 = - 0.80 ⇒ -0.80² = 0.64 * 5pax = 3.20
1 pax : 31 - 30.80 = 0.20 ⇒ 0.20² = 0.04 * 1pax = 0.04
3 pax : 32 - 30.80 = 1.20 ⇒ 1.20² = 1.44 * 3 pax = 4.32
Variance : (3.20 + 0.04 + 4.32) / 9 pax = 7.56 / 9 = 0.84
Standard deviation is simply the square root of the variance.
Standard deviation = √0.84 = 0.916
0.916 round to nearest hundredths is 0.92
0.916 round to nearest tenths is 0.90

The answer of this question is option A
If I buy 2 shirts for $20 and get 25% off, I will have spent $15. This would come out to $7.50 per shirt.
If I buy 3 shirts for $30 and get 30% off, i will have spent $21. Which is $7 per shirt.
The answer is option B
