This is the way I do it to find the average.
10 girls times 70 = 700
15 boys times 80= 1200
700+1200=1900 all their scores
1900÷25 (number of boys and girls)=76 or 76%
Answer:
1/3
Step-by-step explanation:
Half of two of something would be only one of that something. In this case the something is 1/3 so our answer is 1/3.
The exponential function shown in the graph is 3^x, so (1/2)3^x is a shrink of it.
Selection B is appropriate.
