Answer:
-4
Step-by-step explanation:
Y = -4x+-2
Not quite sure how to explain it on here but substitute it and it works. :)
<span>In triangle WXZ,
Line WY is an altitude (as shown in the attached picture)
Now, it is given that:
</span><span>If ΔYWZ ~ ΔYXW
</span>∠WXY = ∠WZY
<span>
Then, we can also conclude
</span>∠WYX = ∠WYZ = 90°....(1) (because WY is the altitude)
Now, in any triangle, the sum of all the three angles is 180.
In triangle, WXY, ∠WYX = 90° (From 1)
Therefore, WXY + XWY = 90°
Similarly, in WZY.
Hence, we conclude that XWZ is a right angle.
Answer: OPTION C.
Step-by-step explanation:
For this exercise it is important to remember the following:

Knowing this and based on the information provided in the exercise, you can make the conversion from kilograms to ounces. This is:

According to the exercise, Miriam's procedure was:

So you can identify that she made a mistake.
Notice that:
1. Miriaim multiplied correctly.
2. Butt the third fraction should be
and not
.
Answer:
m= -12
Step-by-step explanation:
-15m-30=-12m+6
-3m=36
m=-12
There are

ways of selecting two of the six blocks at random. The probability that one of them contains an error is

So

has probability mass function

These are the only two cases since there is only one error known to exist in the code; any two blocks of code chosen at random must either contain the error or not.
The expected value of finding an error is then
