<span>The number of ways to permute three correct answers among five questions is 5Choose3 which is 5!/(3!*2!) which equals 10.
We must then have the correct answer three times which happens .25 of the time, and two wrong answers 75 of the time.
So the probability is 10*0.25^3*.75^2 which is 0.087890625 or roughly an 8.8% chance.</span>
Answer:
See below.
Step-by-step explanation:
Use the same method as before. Go from each original point in a direction perpendicular to the line of reflection, and then go the same distance to the other side of the line.
I'm not sure but I think it is A: She will not study drug-2 or drug-1. This is because she wants less of this protein being released by the cells, but using the drug increased the level instead. Please rate low stars if this is incorrect so in the future if this turns out to be incorrect, people won't be mislead to pick the wrong answer
Answer:
D
Step-by-step explanation:
Answer:
32
Step-by-step explanation:
This is an equilateral triangle, the 3 sides are equal.
Also, that means 3 angles are equal.
Given the 2 angles, we can say:
2x - 4 = 5y
Also, the angle is "5y" as they are equal.
Sum of 3 angles of a triangle is 180, so we can write:
2x - 4 + 5y + 5y = 180
2x + 10y - 4 = 180
2x + 10y = 184 [Equation 2]
From the first equation we can solve for y:

Now, we plug this into Equation 2 and find x:

So x is 32
