Answer:
$1.59 for a pint,
two dollars for a quart,
299 for a gallon
Step-by-step explanation:
Since, rate is used to compare different kinds of quantities and it is the ratio of the quantities,
Also, unit rate states the amount of first quantity corresponding to the unit amount of second quantity,
When we talk about the unit rates for a quantity,
Then it shows the price of the quantity per unit amount.
Thus, by the above explanation it is clear that,
The unit price for representing the price of juice would be,
$1.59 for a pint,
two dollars for a quart,
299 for a gallon.
Note : we do not consider 'one dollar for 12 ounces' a unit price because it is not the price per 1 ounce.
To do that you'll need the mean and standard deviation of all the scores. Can you provide this info?
For example: Supposing that the mean of these scores were 52 and the standard deviation 3. You'd need to find the "z-score" of 57 in this case.
57 - 52
It is z = ------------ , or z = 5/3, or z = 1.67.
3
Find the area to the left of z = 1.67. Multiply that area by 100% to find the percentile rank of the score 57.
Answer:the answer is A
Step-by-step explanation:
10% = 5
80% = 40
2% = 1
82% = 41
41
