Answer:
605.5
Step-by-step explanation:
When you do a frequency table for this question,the zigma F becomes 2 and the zigma fx becomes 1211.Because you will multiply the marks by the frequency to get the zigma fx so after getting them you add it.Which becomes 403+808=1211.the formula for finding the mean too is zigma fx/zigma f: 1211/2=605.5

Answer:
The jumbo pack is a better deal
Step-by-step explanation:
The better deal of two is the one that offers a lower cost per ride. Considering the two deals, the cost per unit ride for;
a jumbo pack of 50 ride tickets for $45 = $45/50
= $0.90 per ride
a medium pack of 30 ride tickets for $28.50
= $28.50/30
= $0.95
From the computations above, the medium pack (at $0.95) is more costly than the jumbo pack (at $0.90). Hence the jumbo pack is a better deal for Franco.
