Answer:
"2.82" seems to be the correct solution.
Step-by-step explanation:
As we know,
A bag (Bag A) contains,
Red balls = 3
Blue ball = 1
A second bag (Bag B) contains,
Red balls = 1
Blue ball = 1
Now,
⇒ P(Bag A, red ball) = 
On substituting the values, we get
⇒ = 
⇒ = 
Similarly,
Probability of second bag will be:
⇒ P(Bag B) = 
hence,
In the first bag (Bag A), the expected number of red balls will be:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
The angle terms tell the degrees of each angle and what they look like in a parallelogram or triangle
First step would be using this logarithm rule
on right side.
Hope this helps.
I am going to show you the procedure with any slope (given that you did not write the value of the slope)
general slope value: m
generic point (x1,y1)
Formula: y - y1 = m (x -x1)
y - y1 = mx - mx1
y - mx - y1 + mx1 = 0
x1 = -2 , y1 = -3 =>
y - mx - (-3) + m(- 2) = 0
y - mx + (3 -2m) = 0
Now suppose a value for m. Lets say it is m = 5.
y - 5x + (3 - 2*5) = 0
y - 5x + (3 - 10) = 0
y - 5x + (-7) = 0 and that is the standard form if the slope is 5. Now you can do the same with any slope.
The best fit curve for #1 is D. The easiest way to check these is by pluggin in to the equation and seeing if they come close. By doing just the first ordered pair along, it is apparent that only D will work.
With x = 1 input
A) -36
B) 24.2
C) 17.5
D) 11.58
#2 is also D. We can tell this because multiplying any of these options always results in a middle term between them. For instance, if you multiply out C, you will not only get x^4 and x^4, but you will also get terms such as 4x^2y^2 in the middle.
