In a survey of 200 students, 70 were taking mathematics and 40 were taking psychology a) what is the least number of students who could have been taking both courses? b) what is the greatest number of students who could have been taking both courses? c) what is the greatest number of students who could have been taking neither course? a) the least number of students who could have been taking both courses is b) the greatest number of students who could have been taking both courses is c) the greatest number of students who could have been taking neither course is enter your answer in each of the answer boxes o type here to search esc f1 f2 f3 f4

i have no answer for this maybe o 7 units

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

won't that be plagrisim thought?
