I think its b iam not to sure i have the same question myself
Answer:
<h2>AB = 38</h2><h2 />
Step-by-step explanation:
|<----------------- AB ------------------->|
A--------------------M--------------------B
5x + 4 3+16
since M is at midpoint, AM = MB
5x + 4 = 3 + 16
5x = 3 + 16 - 4
x = 15 / 5
x = 3
AB = AM + MB
AB = 5(3) + 4 + 3 + 16
AB = 15 + 23
AB = 38
For two lines to be perpendicular, their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, in this case our reference line has a slope of -3 so:
-3m=-1 divide both sides by -3
m=-1/-3
m=1/3
So the perpendicular line will have a slope of 1/3
Answer:
There is no question stated. If one assume the question is "Does the probability of picking the same color pen change after the first try?," the answer is "No."
Step-by-step explanation:
When the pen is replaced, the probability reverts back to the original value:
There are 7 pens:
5 Blue
2 Red
The probability of picking a red or blue pen on the first try is:
Red = 2/7
Blue = 5/7
When the pen is replaced, the probabilities return to the original values.
ANSWER
EXPLANATION
We want to simplify
We multiply the first fraction by the reciprocal of the second fraction to obtain,
We cancel the common factors to get,
This gives us,
