Answer:
(mn+n²)/(m+n)
Step-by-step explanation:
probability of blue marble= n/(n+m)
probability of red marble= m/(n+m)
probability that process stops = Probability of both blue + probability of both red= n/(n+m) × n/(n+m) + m/(n+m)×m/(n+m)
= (n²+m²)/(n+m)²
P(1st marbel is blue)= P(blue and red) + P(blue and blue)
= mn/(n+m) + n²/(n+m)
= (mn+n²)/(m+n)
P(1st marble is blue | process stops)= ( (mn+n²)/(m+n)× (n²+m²)/(n+m)²)/ ((n²+m²)/(n+m)²)
= (mn+n²)/(m+n)
Answer: (2,-2)
Step-by-step explanation:
Rotating 90 degrees counterclockwise (about the origin) maps (x,y) onto (-y,x), so the answer is <u>N'(2,-2)</u>
Answer:
i think it is a but there are algebra caculators online
Step-by-step explanation:
The answer is C because the radius is half of the cylinder which is 2 so the Diameter will be 4 meaning the whole cylinder and 8 times 4 is 32.
I would really appreciate if I got brainliest :)
Answer:
A
Step-by-step explanation:
Ratio means comparison, so we have to compare the two given examples, in this state empty and occupied.
one of the most important things to look for during ratios is what comes first. In this statement it says empty to occupied, not occupied than empty/.
if we know that empty is 34 and occupid is 16 than we know our answer is A
Please mark me branliest.
Have a great day!
