<span>2w - 5(w+1) = 3w + 1
The first step here is to distribute the -5 to everything inside the parentheses.
</span><span>2w - 5w - 5 = 3w + 1
Now combine like terms on the left side.
-3w - 5 = 3w + 1
Add 3 to both sides.
-5 = 6w + 1
Subtract 1 from both sides.
-6 = 6w
Divide both sides by 6.
-1 = w
So the answer is:
w = -1</span>
Suppose we have a quadratic equation of the form:
The axis of symmetry of the parabola is given by:
From here, we must clear the value of a.
For this, we follow the following steps:
1) Pass 2a multiplying to the other side of the equation:
2) Clear the value of a by passing 2x to divide:
Answer:
The denominator of the fraction is 2x.
Attach a image (The problem) to it so then I can understand it much more better
By definition of independence, 
and 
are independent if 
. So neither the second nor third options can possibly be correct.
We have
which are not equal, so no, and are not independent because the probabilities are not equal (last option).
Yes because the median and range are not a function of the totality of the sample set, the median is just value that is halfway of the set. and the range are the difference of the highest and lowest value. as long as the lowest values, highest value and the halfway value are the same in each set the median and range will be equal no matter what are the other values of the set.
