Area of a rectangle can be calculated by multiplying the length by the height.
So:
l x w
3 x 13
39 cm squared
Area of a triangle can be calculated by multiply the length by the height and dividing by two. So:
1/2 x l x w
1/2 x 10 x 8
40 m squared
6 =2(x+8)-5x
6 =2x+16-5x
6-16=2x-5x
-10=-3x
10=3x
x=10/3
hence proved
Answer:
0.875
Step-by-step explanation:
they're proportional.
I’m doing algebra too and I’m stuck!!!
Answer:
C. The normal distribution can be used because the original population has a normal distribution.
Step-by-step explanation:
When the original population has a normal distribution, we can use the normal distribution to solve the exercise.
In this problem, we have that:
The original population are the adult females.
The problem states that:
The overhead reach distances of adult females are normally distributed with a mean of 202.5 cm and a standard deviation of
7.8 cm.
So the correct answer is
C. The normal distribution can be used because the original population has a normal distribution.
