Given two points (x₁,y₁) and (x₂,y₂), the slope of the line passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
In this case, the points are (-5,-4) and (1,-3) and the slope would be:
m=(-3+4)/(1+5)=1/6
Answer: the slope would be 1/6
Answer:
a. [0.137, 0.503]
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
A sample of 25 students in the lab, of whom 8 smoke. So 
95% confidence interval
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The correct answer is:
a. [0.137, 0.503]
Set up a ratio:
1/50 = x/480
Cross multiply:
50x = 480
Divide both sides by 50:
X = 9.6
The distance on the map is 9.6 cm
Answer:
He was an accomplished architect who designed the Virginia State Capitol, the rotunda at the University of Virginia, and of course his own beautiful Monticello. He was a dedicated farmer and horticulturist, experimenting with crop rotation and redesigning the plow.

Answer:
X = 30
Step-by-step explanation:
20^2 + 23^2 = x^2
400 + 529 = x^2
929 = x^2
√929 = √x^2
X = √929
X = 30.48
