What we can say with a good deal of certainty is that our sample is biased towards the higher spectrum and that the real value of the mean for our population is lower than the obtained value of our sample. If this is true, we should expect for the standard deviation to be higher than in the population.
There are several information's of immense importance in the problem. Based on these information's the answer to the question can be easily reached. The only thing that has to be kept in mind is the calculation part, otherwise it is a simple problem.
Now it is given that:
A large chocolate shake takes 8/9 of a pint of milk.
Then
Amount of milk required to make medium shake = (8/9) * (1/7) of a pint
= 8/63 of a pint
Then it can be said that for making a medium chocolate shake , 8/63 of a pint of milk is required. This is the simplest form of the fraction and it cannot be expressed as a mixed number since the denominator is higher than the numerator.
For the fast food company:
Cost of 100 hamburger buns = $120
Hence, cost of 5 hamburger buns = (5*120)/100 = $6
For the customer:
Cost of 3 hamburger buns = $6
Hence, cost of 100 hamburger buns = (100*6)/3 = $200
The fast food company bought 100 buns for $120, and sold those 100 buns for $200.
Hence, the profit per 100 buns = 200 - 120 = $80

The correct question is:
Jane buys 7/3 yards of fabric to make a cat bed. She starts the project by cutting 4 feet of fabric off the end. How many feet long is the remaining piece of fabric?
Answer:
There are 3 feet remaining.
Step-by-step explanation:
Jane cuts 4 feet from 7/3 yards, to know how many feet long yard is remaining, first we need to know how many feet make a yard, convert 7/3 yards to feet, and find the difference between the feet cut and the total feet available.
3 feet = 1 yard
x feet = 7/3 yards
3 × 7/3 = x × 1
x = 7
Therefore, 7 feet is 7/3 yards.
Now, she cuts 4 feet, do we have
(7 - 4 = 3) feet remaining.
Therefore, there are 3 feet remaining.
The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours.
Temperature drops by 5°c per hour
So we find the temperature after 6 hours
In 1 hour temperature drops= 5°c
So in 6 hours = 6* 5 = 30°c
In 6 hours , temperature drops by 30°c
the actual temperature is 20°c. after 6 hours the temperature becomes
20°c - 30°c= -10°c
So, after 6 hours the temperature will be -10°c
Daryl plans to be gone for at least 6 hours. so its 6 hours or more than 6 hours
In 6 hours or more than 6 hours , the temperature will drop less than -10°c.
So, Daryl should move his plant to a warmer location before leaving
