Answer:
25%
Step-by-step explanation:
The median score of 70% indicates half of the student scored less than 70%.
An upper quartile of 85% means 3/4 of the students scored less than 85% or, stated in another way, 1/4 of the students scored above or equal to 85%.
From sentence 1, 50% of the students scored below 70%.
From sentence 1, 75% of the students scored below 85%.
The percentage that score between 70% and 85% is 75% - 50% = 25%
Answer:
Simple interest = $7.50
Step-by-step explanation:
Simple interest = Principal *rate *time
S.I = P*r*t
Principal ; p = $450
rate ; r = 5% or 0.05 as a decimal
time; t = 4 months , however, convert this to years by dividing by 12;
t = 4 / 12
Next, plug in the numbers into the formula;
S.I = 450 *0.05*
S.I = $7.5
Therefore simple interest in 4 months becomes $7.50
