Step-by-step explanation:
<u>Y2 - Y1</u>
X2 - X1
<u>3 - 1</u>
2 - 1
= 2
y - Y1 = m (x - X1)
y - 1 = 2(x - 1) --- IN POINT SLOPE FORM
y - 1 = 2x - 2
+ 1 + 1
y = 2x - 1 --- IN SLOPE INTERCEPT FORM
QUESTION 12:
Slope intercept form -
- y = mx + b
- m represents the slope
- b represents the y - intercept AKA the starting point
- When the slope is negative, you go down
- When the slope is positive, you go up
ABOUT PROBLEM:
- Since the slope is negative, you go down 4, right 3, but start from the 2 then start doing the slope
- You have to put 2 on the y - line because it's the y - intercept AKA starting point
y = -4/3x + 2
We can break this down by removing the parenthesis first:
-2 + 
+ 5 - 
In order to continue, you have to simplify the square roots by factoring it and taking out i:
-2 + 
+ 5 - 
Combine like terms:
-3 - 
<-- that's the answer
Hope I helped :)
We're told that
a. We want to find 
. By definition of conditional probability,
By the law of total probability,
Then
(the first equality is Bayes' theorem)
b. We want to find 
.
since 
.
Answer:
-5
Step-by-step explanation:
4x0.5=2
2x0.5=1
2+1=3
3-8=-5
Answer:
A. 8/7
Step-by-step explanation:
<h3>Step 1 </h3>
4/7 - (-4/7) --> 4/7 + 4/7
The two minutes turn into a plus, removing the bracket.
<h3>Step 2</h3>
4/7 + 4/7 = 8/7
Add the two fractions together.
