Interquartile range = 50-29 = 21.
Answer: 46
Step-by-step explanation:
percentage scored = 92
number of correct question = x
total number of questions = 50
The formula for calculating the percentage scored
= number of correct question / total number of questions x 100
That is
92 =
x 

cross multiplying :
x 

dividing through by 100 , we have

Therefore, she got 46 questions right

the middle number of the given list
Answer:
30 and 17
Step-by-step explanation:
Using Pythagoras' theorem, that is
The square on the hypotenuse of a right triangle is equal to the sum of the squares on the other 2 sides, thus
(1)
c² = 18² + 24² = 324 + 576 = 900
Take the square root of both sides
c =
= 30
(2)
c² = 8² + 15² = 64 + 225 = 289
Take the square root of both sides
c =
= 17
