A line that is parallel to another has exactly the same slope as the other.
so a parallel line to that line above, will have the same slope hmmm what is the slope of <span>y=3/4x+2 anyway?
well, notice, since it's already in slope-intercept form </span>
Answer:
Step-by-step explanation:
The radius r can be found from the relationship
The point is in Quadrant II (-, +), so use the inverse cosine function to find the angle.
See the attached image.
Answer:
and 
Step-by-step explanation:
The null hypothesis 
states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value. We can write the null hypothesis in the form 
In this context, the investigator's null hypothesis should be that the average total weight is no different than the reported value by the FAA. We can write it in this form .
The alternative hypothesis 
states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. We can write the alternative hypothesis in one of three forms
The investigator wants to know if the average weight of passengers flying on small planes exceeds the FAA guideline of the average total weight of 185 pounds. He should use as his alternative hypothesis.
Answer:
read the problem
Step-by-step explanation:
a. write down the facts and figures
b. read the problem
c. find a relationship between what is given and what must be found
d. do the work
As shown in the given figure
line a // line b ⇒ given
MR and NP are transversals
So, for ΔMOP and ΔRON , we can conclude the following
(1) ∠1 = ∠2 ⇒⇒⇒ alternative angles are congruent
(2) ∠ MOP = ∠ RON ⇒⇒⇒ vertical angles are congruent
(3) ∠ 4 = ∠ 3 ⇒⇒⇒ alternative angles are congruent
So, from 1,2 and 3
∴ ΔMOP <span>~ </span>ΔRON by AAA-Rule
