An urn contains b black balls and r red balls. One of the balls is drawn at random, but when it is put back in the urn c additional balls of the same color are put in with it. Now suppose that we draw another ball.
Required:
Show that the probability that the first ball drawn was black given that the second ball drawn was red is b/(b r c).
Answer:
Please see the explanation below for proof
Step-by-step explanation:
Probability of choosing black ball from the bag
[tex]\frac{b}{b+r}[/tex]
Probability of choosing red ball from the bag
[tex]\frac{r}{b+r}[/tex]
After the addition of c balls of correspondent color –
P (R2/B1) [tex]= \frac{r}{(r+b+c)}[/tex]
P (R2/B2) [tex]=\frac{r+c}{(r+b+c)}[/tex]
B1 and B2 are mutually exclusive event
P (B1/R2) = [tex]\frac{\frac{r}{(r+b+c)} *\frac{b}{b+r}}{\frac{r}{(r+b+c)}*\frac{b}{b+r} + \frac{r+c}{(r+b+c)}* \frac{b}{b+r}}[/tex]
P (B1/R2) [tex]=\frac{b}{(r+b+c)}[/tex]
Hence, Proved

Evaluate the expression 2y + 3.5. Evaluate the expression for y=1.8, y=4, y=6.9. (there should be three answers)
Answer:
1. 7.1
2. 11.5
3. 24.2
Step-by-step explanation:
you use P.E.M.D.A.S. for all the equations.
so you do thr multiplication and then the addition
1. 2(1.8)+3.5= 3.6+3.5= 7.1
2. 2(4)+3.5= 8+3.5=11.5
3.2(6.9)+3.5= 13.8+3.5= 24.2

1.Write an equation in point slope form given a point (-5,2) and slope 3/5
Question 2
Write an equation in slope intercept form given a slope -5 and y intercept as (0,-4)
Answer:
1. y - 2 = (3/5) (x + 5)
2. y = -5x - 4
Step-by-step explanation:
Slope form - y1 - y = m (x1 - x)
Slope intercept - y = mx + b

Answer:
It costs $9
Step-by-step explanation:
Lets look at the ratio:
2/3
We need x:
6/x
Make an equation using the butterfly method:
3(6) = 2x
Simplify:
18=2x
Divide both sides by 2:
x=9
It costs $9

Jana paid an initial fee of $75 to join a fitness gym. She pays $15 per month for her membership. How many months did she have the membership if she spent a total of $255.
asap ill give brainlyist
Answer:
12 months
Step-by-step explanation:
Set up a formula; 75 + 15x = 255
Now, solve for x, which is number of months.
subtract 75 from both sides.
15x = 180
divide both sides by 15.
x = 12
x is equal to 12 - she would have had to have the subscription for 12 months to spend 255$.
A $65 drone is on sale for $51.35. What is the percent of discount?
Answer:
20% off
Step-by-step explanation:
Answer:
21%
Step-by-step explanation:
To calculate the percentage discount between two prices, follow these steps:
Subtract the post-discount price from the pre-discount price.
Divide this new number by the pre-discount price.
Multiply the resultant number by 100.
$51.35-65=13.65
13.65/65= -0.21
-0.21*100=-21
Rewrite 30x + 75 using the distributive property with the greatest

In AGHI, GI is extended through point I to point J, mZGHI = (2x - 3)º,
mZIGH = (2x + 15)°, and m_HIJ = (7x – 18)'. Find mZGHI.
Answer:
m<GHI = 17°
Step-by-step explanation:
m<GHI = (2x - 3)°
m<IGH = (2x + 15)°
m<HIJ = (7x - 18)°
<HIJ is an exterior angle of ∆GHI
<GHI and <HIJ are both interior angles of ∆GHI that are opposite to the exterior angle.
Therefore, based on the exterior angle theorem of a triangle, we would have the following equation:
m<GHI + m<IGH = m<HIJ
(2x - 3)° + (2x + 15)° = (7x - 18)° (substitution)
Solve for x
2x - 3 + 2x + 15 = 7x - 18
Add like terms
4x + 12 = 7x - 18
4x - 7x = -12 - 18
-3x = -30
Divide both sides by -3
x = 10
✔️m<GHI = (2x - 3)°
Plug in the value of x
m<GHI = 2(10) - 3 = 20 - 3
m<GHI = 17°

Given that the function g is defined by the rule g(x)=3-2x,determine the following
g(a)=
Answer:
The value of g(a) is:
g(a) = 3 - 2aStep-by-step explanation:
Given
As the function g(x) is given by
[tex]g(x)=3-2x[/tex]
To determine
g(a) = ?
In order to determine g(a),
substitute x = a in the function g(x) = 3 - 2x
g(x) = 3 - 2x
g(a) = 3 - 2(a)
g(a) = 3 - 2a
Therefore, the value of g(a) is:
g(a) = 3 - 2aHELP ASAP !! During one team's session, the ratio of the number of games the team won to the number of games the team played was 4 to 12. The team played 42 games. How many games did the team win? A) 17 Games. B) 11 Games. C) 10 Games or D) 14 games.

Answer:
a= 158
b=22
Step-by-step explanation:
First we have to find b in order to find a.
To find b we need to add up the two angles we know the value of and subtract it from 180.
90+68= 158
180-158=22
We know b is 22 because the sum of all angles in a triangle is always 180.
Now that we have b we can find a.
we know that a+b=180 so all we have to do is subtract 22 from 180 to get 158.
Answer:
b is 22° and a is 158°
Step-by-step explanation:
b can be calculated by angle sum property and a can be calculated using exterior angle sun property
