Answer:
Concept: Caclulating Standard Variables
- We have a five number summary which is more than enough information to calculate our mean.
- The mean is the sum of all the numbers divided by the nth number of numbers.
- Note that we can only find a rough estimation not the EXACT value
- We do (min +max + 2(Q1+median+Q3))/8
- Now let's plug in our values!
- (0+85.3+2(8.4+17.4+30.9))/8
- Which gives us option B
- Hope this helps, give brainlist
First number is a and second one is 2a+4
a(2a+4)=48
a(a+2)=24
a^2+2a-24=0
(a+6)(a-4)=0
the question says a is negative so a=-6 b=-8
