Step-by-step explanation:
5n-2
5(4) - 2
20-2=18
A= 18
5n - 2 =48
5n=48+2
5n=50
divide by 5
n= 10
B=10
Answer:
Step-by-step explanation:
Is there any other information lol
1. N is a midpoint of the segment KL, then N has coordinates

2. To find the area of △KNM, the length of the base MK is 2b, and the length of the height is a. So an expression for the area of △KNM is

3. To find the area of △MNL, the length of the base ML is 2a and the length of the height is b. So an expression for the area of △MNL is

4. Comparing the expressions for the areas you have that the area
is equal to the area
. This means that the segment from the midpoint of the hypotenuse of a right triangle to the opposite vertex forms two triangles with equal areas.
Order set...{160,165,170,240,240,450}
The "mean" is the arithmetic average of the elements...
mean=(160+165+170+240+240+450)/6=237.5
The "median" if the set has an odd number of terms is the middle term, if the set has an even number of terms, it is the average of the middle two terms.
In this case the number of elements is even and the middle two terms are 170 and 240 so:
median=(170+240)/2=205
The "mode" is the term which appears the most in the set, so in this case:
mode=240
