A class of 37 students took a test worth 100 points. The five-number summary of their scores is 55, 67, 73, 81, 98. Identify the
tankabanditka [31]

Answer:

At least 18 students scored below a 67.

Step-by-step explanation:

Given the 5 number summary of scores obtained by 37 students in a test worth 100 points :

55, 67, 73, 81, 98

Minimum = 55

Q1 = 67

Q2 = 73

Q3 = 81

Maximum = 98

Q1 = first quartile = 25%

Atleast 25 % scored below 67 (True)

25% of 37 students = 0.25 * 37 = 9.25

Atleast 9 students scored below 67 (True)

Median, Q2 = 50%

Score between Q2 and Q1 = 50% - 25% = 25% ;

Hence, atleast 25 students scored between 73 and 67 ; meaning (0.25 *37) = 9.25 students Hence. Atleast, 9 students scored between 73 and 67 (True)

Third quartile = 75%

Percentage above third quarterile = (100 - 75)% = 25%

Hence, atleast 25% scored above 81 (True)

The false statement is At least 18 students scored below a 67.

If a price is 60$ and it gets a 15% markup,what would the final price be?
Shkiper50 [21]
Simple,

to find the rate of selling price price based on cost....-rate of cost+rate of the markup..

In work..

S%=C%+M%

The cost is $60 and C is 100%, also you know M%=15%

S%=100%+15%=115%

Rate of the selling price=115%

Step 2: Find the selling price

S=S%*CS=115%*$60S=1.15*60=$69

The selling price at a 15% markup is $69.

Thus, your answer.
