A group of 50 students at the Namibia University of Science and Technology, take at least on of these subjects: Calculus(C) and ANOVA(A). 17 take both subjects, 9 take Calculus only. 8 take ANOVA only and x take neither subjects.

4.1 Represent this information on a venn diagram.

NB: For questions 4.2 to 4.4 use appropraite set notations.

4.2 Find the value of x

4.3 Find the number of students taking Calculus or ANOVA

4.4 Find the number of students taking ANOVA.

4.5 Find the number of students who are not taking Calculus.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
