30÷80=0.375
0.375=37.5%
So the answer is 37.5%
Well first, you want to find their least common multiple, which is 15.
So you want 15 red roses and 15 white roses.
In order to get that, you want 5 packages of red roses, because 3*5=15.
And you’ll want 3 packages of white roses because 5*3=15.
Answer:
Option B.
Step-by-step explanation:
Eric states the applied interest is simple interest. We need to check whether the this statement is true or false.
In simple interest, the amount of deposit increased at a constant rate. It means the difference between future values of any two consecutive years will same.
Difference between future values of first two years.
Difference between future values of 2nd and 3rd year is
Since d₁≠d₂, therefore, the given statement is false.
Thus, the correct option is B.
Answer:
113.14 square inches
Step-by-step explanation:
Area of circle is given by 
where r is the radius. The radius is usually half the diameter hence for this case the radius will be 0.5*12=6 inches.
Taking 
as 
then the area will be
Therefore, rounded off to 2 decimal places the area is approximately 113.14 square inches
Answer:
Mode
Step-by-step explanation:
The answer is Mode. Mode is basically a number or data item that appears most frequently in a data set. First lets see how we find Mode. To find the Mode in the data set, first the numbers or data items are placed in order. Then it is counted that how many times each number appears. A number or data item that appears most frequently is the mode.
So lets a student builds unifix cube towers to represent the ages of the five children as following:
3 1 2 2 4
Now the student first places them in order from smallest to largest
1 2 2 3 4
Now she removes the shortest and tallest tower. Shortest is 1 and tallest is having 4 cubes. After removal of shortest and tallest tower:
2 2 3
Then removes the next shortest and tallest tower. Now the shortest tower has 2 cubes and tallest has 3 cubes. After removal of shortest and tallest tower:
2
The tower in the middle is remaining i.e. 2
So as you can see the most frequently occurring from 1 2 2 3 4 is also 2 as it appears twice. So that means student has found Mode. Although the same method is used to find the median too but here the most appropriate option is Mode. Mean is the way to find the average but it is computed by adding the numbers in the data set with the total size of data. So its not an appropriate option because the method that the student followed does not match with the method to compute mean. Also range is not a valid option because range finds the difference of the largest and smallest number and the method that student used is different from the method to compute range. If we compute the difference between largest and smallest number we get 3.
