Let's consider the first number to be and the second number to be
. Based on the information in the problem, we can create the following equations:
Now, we can solve the equations through systems of equations. One way of doing this is by multiplying one of the equations so that there is a term in both equations which can be removed by addition or subtraction. In our case, we can multiply the entire first equation by 2 to get:
Now, subtract from both equations to get:
Now that we have found , "plug" it back into an equation to find
:
Our answers are s = -4 and f = 9.
Answer: a= 16
Step-by-step explanation:
We have the following expression:
To find the value of the coefficient "a" you must use the distributive property to multiply the expression:
until you transform it to the form:
Then we have
Therefore the value of a in the polynomial is 16
Answer:
The probability of selecting the color of ball that you just selected(a red ball) is
Step-by-step explanation:
From the question we are told that
The total number of colored balls is n = 10
The number of red balls is r = 2 red
The number of white ball is w = 4
The number of blue balls is b = 4
The number of balls to be selected is N = 2 balls
The cost of playing picking a ball is c = $10
The winnings is
Here P(A) is the probability of obtaining the exact sequence of result and from the question it is P(A) = 0.10
Generally my price according to the question is
=>
Let assume we selected a red ball
Generally the probability of selecting a red ball is mathematically represented as
