For this case we have the following quadratic equation:
To factorize, we must find two numbers that when multiplied result in -6 and when added together result in +5. These numbers are: -1 and +6
Then we factor:
Thus, the roots are:
So, Gisele was wrong in step 2. She couldn't find the correct values to factorize.
Answer:
Gisele was wrong in step 2. She couldn't find the correct values to factorize.
Answer:
19
Step-by-step explanation:
19x-(7+x)+8+x
substitute x with 2
--> 19*2-(7+2)+8+2
-->38-9+10
-->38-19=19
Considering the given discrete probability distribution, it is found that the expected share is of 10%.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the distribution is given by:
Hence the expected value is given by:
E(X) = 0.2 x 0.05 + 0.6 x 0.1 + 0.2 x 0.15 = 0.1 = 10%.
The expected share is of 10%.

Answer:
C. (-7, 4)
Step-by-step explanation:
Diagonals of a parallelogram share a common midpoint
Let the fourth vertex be (x,y)
(-2-4)/2 , (4+0)/2 = (x+1)/2 , (y+0)/2
-3 , 2 = (x+1)/2 , y/2
-3 = (x+1)/2
x + 1 = -6
x = -7
y/2 = 2
y = 4
