The value of P(B|A) is 0.25.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
We have P(A) = 0.40 and P(B) = 0.5
and, P(A and B) = 0.10
Using Conditional Probability
P(B|A) = P(A ∩ B)/P(A)
Substitute the values of P(A), P(B) and P(A ∩ B),
P(B|A) = 0.10/ 0.40
P(B|A) = 0.25

solve each system of equations by substitution
-4x+y=-5 and 2x+y=7
Answer:
x = 2 and y = 3
Step-by-step explanation:
-4x + y = -5 -------------------(I)
y = 4x - 5 ------------(II)
2x + y = 7 -------------------(III)
Substitute y = 4x - 5 in equation (III)
2x + 4x - 5 = 7
6x - 5 = 7
Add 5 to both sides
6x = 7 + 5
6x = 12
Divide both sides by 6
x = 12/6
x = 2
Plugin x = 2 in (II)
y = 4*2 - 5
y = 8 -5
y = 3

Answer:
The y-intercept is (0,3) and the x-intercept is (-6,0).
Step-by-step explanation:
Since y = 3, we'll start there. 1/2 is our rise over run. You go up one unit, then to the right two units.
We do this because it's positive, otherwise we'd go down and left.

If Mason has, four hours of school work, and he started at 6:30, what time would he have stopped?
Answer:
He would be done by 10:30
Step-by-step explanation:
If you have 6:30 and you add 4 hours to it you end up with 10:30 because, forget the '30' for a second and take 6:00. You go 6 to 7 = 1 hour. 7 to 8 = 2 hours. 8 to 9 = 3 hours. 9 to 10 equals 4 hours. Which is what we are trying to get to. So you take that 10 and add the '30 back to it and you get 10:30.
Hope this helps you :)

The ratio is 1/1.5 so just pick the answers where the first number multiplied by 1.5 is equal to the second number.
For example the first option says 2 and 3.
2 times 1.5 is equal 3 so that is one of the answers.
If an option says 4 and 5, 4 times 1.5 is 6 not 5 so that wouldn't be an answer.

At the end of the week, Warren records the weight in pounds of doggie treats eaten as a negative rational number.Plot the numbers of pounds eaten each week on the numberline. Order the numbers from most pounds eaten to fewest pounds eaten
A number line is a system of showing the locations or positions of directed numbers from the mid point (0).
The plotted number line required is attached to this answer.The order of the numbers from most to fewest pounds eaten is:[tex]-\frac{3}{2}[/tex], [tex]-\frac{5}{4}[/tex], [tex]-\frac{2}{3}[/tex], [tex]-\frac{1}{2}[/tex]
A number line is a system used to show the appropriate locations of directed numbers from the origin (0). A directed number is a number which is either positive or negative. Examples are: -4, 2, 5, -9, [tex]\frac{1}{2}[/tex], +4, +1, etc.
Considering the given question, the given weights in pounds of dogie eaten are:
[tex]-\frac{2}{3}[/tex], [tex]-\frac{3}{2}[/tex], [tex]-\frac{1}{2}[/tex], [tex]-\frac{5}{4}[/tex]
To determine the order from most to fewest pound eaten:
the lowest common factor of the given weights is 12, so that;
[tex]\frac{-8, -18, -6, -15}{12}[/tex]
Thus, the order from most pound eaten to fewest pound eaten is:
[tex]-\frac{3}{2}[/tex], [tex]-\frac{5}{4}[/tex], [tex]-\frac{2}{3}[/tex], [tex]-\frac{1}{2}[/tex]
The number line to show the positions of the numbers is attached to this answer for more clarifications.

a larger number is 7 less than 5 times a smaller number. the sum of the two numbers is 41. find the numbers
Answer:
Step-by-step explanation:
Let's call the first number x and the second y.
From the first condition [tex]x+7 = 5y[/tex]; while from the second [tex]x+y=41[/tex]
It's a simple system of equation, I'd recommend solving by solving both for x and comparing the results.
[tex]\left \{ {{x=5y-7} \atop {x=41-y}} \right.\\5y-7 = 41-y \rightarrow 6y=48 \rightarrow y =8;\\x= 41 - 8 \rightarrow x = 33[/tex]
Answer:
(8,33) or x=8 and y=33
Step-by-step explanation:
A number, x or y is less than 5 times a smaller number: y large number and x smaller number
y=5x-7
y+x=41 is also y=-x+41
5x-7=-x+41
5x=-x+48
6x=48
x=8
Plug in 8=x to the equation
y+8=41
y=33

Work out m and c for the line: 2y − 3x=5
Answer:
m = 1.5 and c = 2.5.
Step-by-step explanation:
2y - 3x = 5
2y = 3x + 5
Divide through by 2:
y = 1.5x + 2.5.
So m = 1.5 and c = 2.5.
