Answer:
17.28in
Step-by-step explanation:
To find the area of a triangle, multiply the base by the perpendicular height (the length from the point opposite the base, to the base, which makes a 90-degree angle with the base), and half it:
7.2*4.8=34.56
34.56/2=17.28
Answer:
There are about 5,357 bees in the hive
Step-by-step explanation:
Let
x -----> the number of bees that leave the hive in one minute
y -----> the approximate number of bees in a hive
we know that
The formula to calculate the approximate number of bees in a hive is equal to

For x=25
substitute


therefore
There are about 5,357 bees in the hive
Answer:
Option C is correct.
Step-by-step explanation:
We have been given total 8 data
Data is : 12,15,18,20,23,23,28
Here, n=7
Median is 
Median is 20.
When one data is added n=8
The median of even number of data is

Median is
Median is 
4th terms is 20
5th terms is 23
Since, median should not be change hence,
Median will be 20.
Therefore, option C is correct.
