Answer:
B. 21
Step-by-step explanation:
The fractions are there to just make the problem seem complicated, but just rewrite it without the fractions.
"What is a common multiple for 7 and 3?"
In this problem it's easy, all you have to do is guess and check.
A: A doesn't work. 7 is not a factor of 18.
B: B works! Both 3 and 7 are factors of 21.
C: C doesn't work. 7 is not a factor of 3.
D: D doesn't work. Neither are a factor of 4.
They only leave us with one solution, B.
The average would be each number of cones sold per day added, and divided by the number of days (3). So this can be translated into the equation (67 + 59 + x)/3 = 60/1. Simplified, that is 67 + 59 + x = 180, then 126 + x = 180, then x = 54.
You can check by adding 67 + 59 + 54, which is 180, and divide by 3 days which is 60. So 54 cones were sold on Sunday.
The answer would be c i think
Histograms are useful when we have data which can be divided into several classes or groups. The histogram shows the trend of each class and the trend among the different classes. For example when we have about 50 different values ranging from 1 to 20, it will be a better approach to draw a histogram in this case by dividing the data into small ranges e.g 1 to 4, 5 to 9 and so on and counting the frequency for each class.
Dot plot is useful when we have a small number of individual values. In this case we can visualize how many times each individual value occurred in the data. This is useful when the number of values in the data is less.
In the given scenario, we have 12 values in total ranging from 1 to 5. So making a dot plot would be the best choice. A histogram would not be useful in this case.
Therefore, the correct answer is option D. Dot plot, because a small number of scores are reported individually
Answer:
$9.14 for 39 oz
Step-by-step explanation:
6.12/24 = 0.255 = 0.26
3.56/14 = 0.254 = 0.25
9.14/39 = 0.234 = 0.24
4.98/18 = 0.276 = 0.28
So,
$9.14 for 39 oz is the best price per ounce
