The coordinates of B' are 3 and -12. so option D is correct (3, -12)
<h3>How to find the coordinates of B'?</h3>
The point P(x, y) may undergo translation to form P' by using a defined translation rule :
If given the rule T(a, b) synch that P undergoes translation on T; then we will have P'(x+a; y+b)
Therefore,
The point B has its coordinates as B(1, - 5)
Translation rule, T(2, - 7) then the coordination of B after undergoing transformation according to T2;
B(1, - 5) - - - > T(2, - 7) - - - - > B'(1+2 ; - 5+-7)
= B'(3, -12)
Hence, the coordinates of B' are 3 and -12. so option D is correct.

Answer: Option D
D. $108
Step-by-step explanation:
We must calculate the expected cost per patient to use treatment method B.
The expected cost for a discrete random variable x is:

Where
is the cost associated with the probability 
In this case, the random variable x is represented by the cost of each treatment.
For treatment B there is a possibility that antibiotic 2 works, in that case the cost x would be $ 100 and 
There is also the possibility that it does not work, in this case the cost x would be $180 and the probability 
The expected cost is:

Hello Nitagomez,
To start the numbers 1 through 6 are on a number cube.
Half of them are even, 2, 4, and 6.
So it makes sense that when you roll the cube 60 times, you should have 30 even numbers. The theoretical probability is 30.
A predication of 20 is 10 less than the expected value of 30.
10 out of 30 is 33%.
The predication is off by 33%, I would argue that it is not a very good prediction.
I hope this helps, Good luck!

Answer:
First question -> y = 2
Second question -> y = 10
Step-by-step explanation:
<u>Step 1: Solve y + 2 = 4</u>
Subtract 2 from both sides
y + 2 - 2 = 4 - 2
<em>y = 2</em>
<em />
<u>Step 2: Solve y - 2 = 8</u>
Add 2 to both sides
y - 2 + 2 = 8 + 2
<em>y = 10</em>
<em />
Answer: First question -> y = 2
Second question -> y = 10
Vertical angle is the angle that is opposite to a specific angle
Thus the angle would be <FOE
or you can name it as <EOF
Makes no difference.
