The average weight in ounce for each piece of chocolate is 0.03.
Step-by-step explanation:
The heart-shaped box containing the chocolates has the weight of 2 pounds
The box contains 68 pieces of chocolates.To find the weight of each piece of chocolate, you divide the weight of the box with the number of chocolate pieces in the box.
This will be 2/68 = 0.0294117647
To the nearest hundredth you check the thousandths value and round off
In this case; 0.0294117647 = 0.03 pounds

From the box plot, it can be seen that for grade 7 students,
The least value is 72 and the highest value is 91. The lower and the upper quartiles are 78 and 88 respectively while the median is 84.
Thus, interquatile range of <span>the resting pulse rate of grade 7 students is upper quatile - lower quartle = 88 - 78 = 10
</span>Similarly, from the box plot, it can be seen that for grade 8 students,
The
least value is 76 and the highest value is 97. The lower and the upper
quartiles are 85 and 94 respectively while the median is 89.
Thus, interquatile range of the resting pulse rate of grade 8 students is upper quatile - lower quartle = 94 - 85 = 9
The difference of the medians <span>of the resting pulse rate of grade 7 students and grade 8 students is 89 - 84 = 5
Therefore, t</span><span>he difference of the medians is about half of the interquartile range of either data set.</span>
Answer:
6 hours
Step-by-step explanation:
She already has $55, so we can subtract that from $395.
395-55 = 340
So now we can figure out how many hours she needs to work. We'll set up the problem like this, where x = the number of hours needed:
60x = 340
Divide each side by 60: x = 5.666(repeating decimal)
Rounding up to the nearest hour, Marie needs to work 6 hours.
