Make a Venn diagram, showing three overlapping circles, label them A for driving alone C for carpool P for public trans put 5 in the intersection of all 3 circles 10 used C and P, so 10 goes in that intersection, BUT 5 are already counted, so place 5 in the outer part of the ...

However, if you want an algebraic solution, rather than a feel-good one, consider the numbers as a arithmetic progression with a = 124 d = 2 n = (986-124)/2 + 1 = 432 terms Sum = 432/2 (124+986) so, the average Avg = Sum/432 = 1/2 (124+986) = 555 as we posited above.

I will assume you defined you first function as f(x) = x+1 also g(x) = x^2 + 2x + 1 the simple ones are where you do one of the arithmetic operations e.g. (f+g)(x) = (x+1) + (x^2 + 2x + 1) = x^2 + 3x + 2 similarly (g/f)(x) = (x^2+2x+1)/(x+1) etc the more complicated ones would...

If we require an arithmetic sequence, then just lay a sliding scale over the numbers from 1-27 and see which string of 9 contains the most primes.

you forgot the h in the original equation, should have been A = (1/2)(b1 + b2)(h) then 2A = h(b1+b2) h = 2A/(b1 + b2)

a) is correct b) If I interpret it correctly first speech: he has 62 jokes available second speech: he has 59 jokes available third speech: 56 jokes .... nth speech: ≥ 3 so we have to find the number of terms in the arithmetic sequence 62, 59, 56 , .... , 3 or 2 or 1 a...

If you verbalize an arithmetic calculation rather than using symbols, you lose the correct sequence of operations e.g. If I say What is 3 plus 8 divided by 4 is it (3+8)/4 or 3 + 8/4 ? different answers! I will suppose it is the usual BEDMAS rule 1/2 + (2/3) ÷ (3/4) = 1...

As per the probability rule Total of all probability is 1 So, P(History)+P( English)+P( Science) = 1 1/3 + 1/6 + P( Science) = 1 P( Science) = 1- (1/3 + 1/6) = 1 - 1/2 P( Science) = 1/2
