Answer:
b
Step-by-step explanation:
9 x 37 = 333
Since 120 students gained less than 70, and 70 is the upper quartile, 120 people are in the 75% of all the students so we need to find the total number of students.
we need to multiply 0.75 (75%) by something to get 120. which is 160 (the total number of all students).
and since 48 is the median score, find 50% of 160 which is 80!
hope this helps :)
Answer:
The answer is C.
Step-by-step explanation:
The equivalents to 1/4 are 2/8, 3/12, 4/16 etc. So the fractions after 1/4 are higher than 1/4. Then you count how many 'x's are in the columns for those measurements and you will get 6.
Doing the equation, You get the answer 85/8 or 85 over 8, converting that into a decimal equals 10.625, now since there's a 6 after the decimal and you want to estimate your answer is 11 . I hoped I explained this well ^-^
