There are 900 calories in 180 crackers. Write 60 calories for 12 crackers as 60/12. Then make x/180, showing that there are 180 crackers with an unknown amount of calories. Cross multiply 60 and 180, which is 10,800. Divide 10,800 by 12, and you get 900.

Answer:
To work out how much it is for a pound of pistachio or almonds:
You subtract 8 from 48 which leaves you with 40 then you divide 40 with 5 which leaves you with 8 (meaning $8 for a pound for almonds) and you add 4 to 8 which gives you 12 ($12 for a pound of pistachios)
then you substitute the answers into a, b, c,d and e.
Therefore, A, C
Step-by-step explanation:
Answer:
1. χ² = 18.548
2. χ² = 23.685
Step-by-step explanation:
1. Confidence level is 99% (α = 0.01), but we're only interested in the left half, so α/2 = 0.005. Degrees of freedom are 7−1 = 6. Looking up in a chi square table, χ² = 18.548.
2. Confidence level is 90% (α = 0.10), but we're only interested in the right half, so α/2 = 0.05. Degrees of freedom are 15−1 = 14. Looking up in a chi square table, χ² = 23.685.
