17/16 is the answer since 1/2 is equal to 8/16. 8+9 is 17
Answer: Option D
Step-by-step explanation:
We can use the binomial formula to solve this problem.
Where p is the probability of success, n is the sample size and x is the number of successes expected.
Note that in this case
(probability that a part is defective)
Then we calculate the probability
You just flip each of the numbers spots - the x and y
we know that
In the right triangle RSQ
------> equation
In the right triangle RST
------> equation
equate equation and equation
therefore
the answer is
the length of SR is
I don't know what 'step 2' is
a² + b² = c²
a = 21² = 441
b = 28² = 784
c = 35² = 1225
441 + 784 = 1225
Leon is correct
