The probability that all marbles are yellow is
(7/20) (7/20) (7/20) = 343/8000
We are given
x = 2 and 3
u = 2.5
s = 0.5
Getting the z score
z = (2 - 2.5) / 0.5 and (3 - 2.5)/ 0.5
z = -1 and 1
The percentage is
1 - 0.1557 = 81.5%
To solve any equation, you do whatever you need to do
to wind up with the unknown quantity all alone on one side.
BUT ... whatever you do to one side of the equation, you must
also do to the other side.
Here, we have the
he original equation: -15 = a/5
Multiply each side by 5 : -75 = a
and bada-bing, THERE's the solution !
Based on the information, it can be inferred that payment option A means a payment of $450, while option B means a payment of $300.
<h3>How much money does each payment option receive?</h3>
The payment options contemplated by the employer are distributed as follows:
Option A
- First week: $200
- Second week: $200 + $50 = $250
- Third week: $250 + $50 = $300
- Fourth week: $300 + $50 = $350
- Fifth week: $350 + $50 = $400
- Sixth week: $400 + $50 = $450
Option B
- First week: $200
- Second week: $220
- Third week: $240
- Fourth week: $260
- Fifth week: $280
- Sixth week: $300
Note: This question is incomplete because there is some information missing. Here is the missing information:
Complete the tables to show how much money would be received for both payment options, each week, for 6 weeks.

The general equation of second degree is
Ax²+By²+Gx+Fy+C=0 ------1
Now the given conditions are
A=1, B=0, C=0
Now,
putting in eq. 1
x²+Gx+Fy=0
x²+Gx= -Fy
For completing square, add both side (G/2)²
x²+Gx+(G/2)²=-Fy+(G/2)²
(x+G/2)²=-F(y-G²/4F)
Or
X²=-FY where X=x+G/2, Y=y-G²/4F
which is the standard eq. of parabola in XY-coordinate.
