I think is C is the first one. B for the second. C for the third. and C again. I hope these are right! have a good day!
Answer:
See below
Step-by-step explanation:
The result of the calculation of area ( L x W ) should have no more significant digits than the lowest factor ....in this case 75 has only TWO significant digits...... the naswer should have the same ...two
75 * 50.3 = ~3800 cm^2
The probability of the 2 events are multiplied to get the result 10/91
so we have the relation 5/14 * x = 10/91
where x is the probability of drawing the second black
so x = 10/91 * 14/5 = 4/13 answer
Alright, lets get started.
The answer Sandra got is correct that is zero but there are some mistakes she made while writing steps.
Incorrect step
Because as per even/odd identity,
Cot (-Θ) = - cot (Θ)
Hence
Now,
It could be written as
0
Hence the answer is 0. : Answer
Hope it will help :)
