Given P(A) = 0.4 and P(B) = 0.6, do the following.(a) If A and B are independent events, compute P(A and B).(b) If P(A | B) = 0.5, compute P(A and B).
Answers
Answer:
Solution in photo
Step-by-step explanation:
Answer:
a) 0.24
b) 0.3
Step-by-step explanation:
Given the following probability
P(A) = 0.4 P(B) = 0.6
a) P(A and B) =P(A)P(B) {Independent)
P(A and B) = 0.4×0.6
P(A and B) = 0.24
b) Given P(A | B) = 0.5, this is a conditional probability
If P(A | B) = P(A and B)/P(B)
Since If P(A | B) = 0.5
0.5 = P(A and B)/P(B)
P(A and B) = 0.5(P(B)
P(A and B) = 0.5(0.6)
P(A and B) = 0.3

Which equation represents the rectangular form of r = 8?
Answers
Answer:
x^2 + y^2 = 64
Step-by-step explanation:
EDGE 2020
The equation that represents the rectangular form of r = 8 is x² + y² = 64
What is rectangular form?Rectangular form, is where a complex number is denoted by its respective horizontal and vertical components.
According to the given problem,
x=rcosθ
y=rsinθ
substituting we have
x=8cosθ
y=8sinθ
Squaring and adding we obtain the
circle's origin centered equation,
x² + y² = 64
Hence, we can conclude, the equation x² + y² = 64, represents the rectangular form of r = 8.

if f(x)=15x-7 then f^-1(x)
Answers
So, we need to find the inverse of the function f(x) = 15x - 7.
To start, we must turn the f(x) into a y.
y = 15x - 7.
Now, we swap all the x variables for the y variables, and swap all the y variables for the x variables!
x = 15y - 7.
Now, we simply must work on isolating y. Assuming you know how to isolate a variable, we must do the steps below -
x = 15y - 7.
Add 7 on both sides.
x + 7 = 15y - 7 + 7.
We cannot add x and 7, as they are not like terms. So, they will remain like that, while the 7 on the right side of the equation is eliminated.
x + 7 = 15y.
Now we are going to divide both sides by 15, thus leaving y by itself.
= 15y / 15.
Since we cannot divide the left side of the equation by 15, it will remain as such. With the y variable completely isolated, our final inverse function will be:
= .
Hopefully, this helps! =)

Write the equation of the line in slope-intercept form that goes through the points: (2, 4) and (7, -1) *
Answers
Answer:
1. slanting upward because the slope is positive one.
2. A: 3/4 B: 4/-3
3. A: 3 B: y=3x-10
1. (-2-7)/(-4-5) = -9/-9 = 1
2. A: (7-4)/(7-3) = 3/4
B: (8-0)/(-6-0) = 8/-6 = 4/-3
3. find the slope first so (4-1)/(2-1)= 3/1. then you plug in point C to find the y intercept so y=mx+b would be 2=3(4)+b which makes it so b is -10. the new equation would be y=3x-10
