Answer:
First answer is 14
Second answer is 25
Step-by-step explanation:
Median is the middle ( 1 2 3 4 5 the median would be 3)
You start at 2 and end at 27
List all the numbers from 2 to 27 and come from both ends until you get to the middle number(s)
In this case there are two 14 & 15
14+15=29 29÷2=14.5
Since there are no decimal answers you are left with 14
Range you take the two end numbers and subtract them (27 & 2)
27-2=25
Hopefully this helps!
ANSWER
The two lines are perpendicular if 
EXPLANATION
Given two lines:

and

We can tell wether these two lines are perpendicular to each other using their slopes.
If the product of their slopes is -1, the then the two line are perpendicular.
For example:
The line

has slope

and the line

has slope

The product of the two slopes is

This implies that:

Therefore the two lines are perpendicular.
Given:
n = 195, sample size.
x = 162, successes in the sample
The proportion is
p = x/n = 162/195 = 0.8308
n* p = 195*0.8308 = 162
n*(1-p) = 195*(1 - 0.8308) = 33
If n*p >= 10, and n*(1-p) >= 10, then the sample proportions will have a normal distribution. This condition is satisfied.
The proportion mean is
μ = 0.8308
The proportion standard deviation is

σ/√n = 0.0269/√195 = 0.00192
At the 95% confidence level, the interval for the population proportion is
(μ - 1.96(σ/√n), μ + 1.96(σ/√n))
= (0.8308 - 1.96*0.00192, 0.8308 + 1.96*0.00192)
= (0.827, 0.8345)
Answer: The 95% confidence interval is (0.827, 0.835)
Answer:
The line equation is:
Step-by-step explanation:
Given
- The point = (4, 8)
- m = -1/4
We know that point-slope form of the line equation is

where
substituting the values m = -1/4 and the point (4, 8)


Add 8 to both sides


Thus, the line equation is:
