Answer: 
or 
Step-by-step explanation:
The complete exercise is: "A chicken salad recipe calls for 
pound of chicken per serving . How many pounds of chicken are needed to make 
serving".
You can convert the Mixed number to a Decimal number. Divide the numerator 1 by the denominator 2 and then add the quotient to the Whole number. Then, you get:
Now divide the numerator 1 by the denominator 8 to write the fraction to a Decimal number. Then:
Let be "x" the amount of pounds are needed to make serving.
Then, you can set up the following proportion:
Solving for "x", you get:
or
It would take the car 5 hours to travel 300km.
Equation used to solve: (120÷2)×6
A) For both sets A and B, calculating the mean, range, and quartiles are a good way of measuring the center and spread. Using standard deviation may not be the best because we do not know whether the distributions are normal or not.
b) For set A, the lowest value is 63, while the highest is 86. An estimate for the mean, based on the average of these, is 74.5. Most of the 70+ values are below 74.5, so we may guess that the mean will be above the median.
For set B, the lowest is 63, while the maximum is 95. The estimated mean would be 79. But since there are more values on the 80+ and 90+ side, the median is likely to be higher than 79.
c) For set A, the mean is 74.79, while the median is 73, therefore the mean is above the median, and the prediction in part b is correct.
Answer:
c ≈ 4.2 ft
Step-by-step explanation:
Using the cosine rule with a = 7, b = 8 and C = 32°, then
c² = 7² + 8² - (2 × 7 × 8 × cos32°)
= 49 + 64 - (112 × cos32°)
= 113 - 94.98
c = 
≈ 4.2 ft ( to the nearest tenth )
