Answer:
18.84
Step-by-step explanation:
Answer:
26 times.
Step-by-step explanation:
Total number of candies = 500.
Probability ( Angie drawing a brown candy) = 130/500 = 13/50.
Probability (Eric drawing a red candy) = 100/500 = 1/5.
So Probability ( Angie drawing brown then Eric drawing a red) = 13/50 * 1/5
= 13/250.
Therefore the expectation of the number of times this will happen
= Probability * total number of draws
= (13/250) * 500
= 13 * 2
= 26 times.
Subtract 7x from both sides
3=9x-13-7x
simplify 9x-13-7x to 2x-13
3=2x-13
Add 13 to both sides
3+13=2x
simplify 3+13 to 16
16=2x
simplify both sides by 2
16/2=x
simplify16/2 to 8
x=8
Answer:
A solution that results in a false statement when substituted back into the original equation.
Step-by-step explanation:
An extraneous solution is one that arises in a solution of equations, but which on closer inspection is not a solution to the original equation. Therefore, they imply an error in the development of the solution of the equation, so they cannot be taken as a valid solution since, when replacing the result with the missing variable, the equation does not obtain the desired result.
B is the correct answer. If you use the distributive property correctly you will see why.
(4x+3)(2x+1)= 8x^2+4x+6x+3
= 8x^2+10x+3
