Since Q and R are independent, this means P(Q and R) = P(Q)*P(R)
<span>P(Q and R) = P(Q)*P(R)
</span><span>P(Q and R) = (4/5)*(4/11)
</span><span>P(Q and R) = (4*4)/(5*11)
</span>P(Q and R) = 16/55
check the picture below.
so, y = -3 is simply a horizontal line, as you see there, and any perpendicular line to that will be a vertical one, whose slope is undefined.
we can check by simply picking two points off the red line hmmm say (-2,2) and (-2, -2)

Answer:
Step-by-step explanation:
hello : Completing The Square
X²+y²-10x-16y+53=0 means : (x²-10x+25-25)+(y²-16y+16-16)+53 =0
(x²-10x+25)-25)+(y²-16y+64)-64+53 =0
(x+5)²+(y-8)² -25-64+53=0
(x+5)²+(y-4)² = 6² standard form
the center is (-5 , 4) and the radius : 6
Twenty-seven minus 3/2of a number (x) is not more than 36.
27 - (3/2)X = 36
What is the number?
(3/2)X = 27 - 36 = - 9
X = (- 9x2)/3 = -18/3 = -6
Check
36 = 27 - (3/2)X = 27 - (3/2)x(-6) = 27 - (-18/2) = 27 - (-9) = 36
The answer to your question above would be: 7z-2/z-7
