Answer:x=-2.30
Step-by-step explanation:
6.95x+16.2-2.36x=3.2x+13
6.95x-2.36x+16.2=3.2x+13
4.59x+16.2=3.2x+13
4.59x-3.2x+16.2=13
1.39x+16.2=13
1.39x+16.2-16.2=13-16.2
1.39x=-3.2
1.39x÷1.39=-3.2÷1.39
X=-2.30
180/5=36
Now since it's a 3:2 ratio you have to multiply 36x2to find out the measure of ABD
36x2=72
72 is your answer
The figure is really just 3 triangles and 1 rectangle, as you see in the picture below.
notice the blue triangle has a base of 3 and a height of 2,
the green triangle has a base of 6 and a height of 1,
the yellow triangle has a base of 2 and a height of 6,
and the rectangle is a 7x6 rectangle.
we can simply get the area of each and sum them up, that's the area of the figure.
Answer:
sample standard deviation is $50
Step-by-step explanation:
Given a population standard deviation of $500 and a random sample of size, n=100.
-The sample standard deviation is calculated using the formula:
Where:
- is the sample standard deviation.
- is the sample size.
- is the population standard deviation
Therefore:
Hence, the sampling distribution has a mean of $1,500 and a standard deviation of $50
Domain is f(x) > 0
range is x is any real number
