Answer: The second number is 96.
Step-by-step explanation:
Let the second number be x
7/8 = 84/x
or, 7x = 672
or, x = 672/7
so, x = 96
I'll leave the computation via R to you. The are distributed uniformly on the intervals , so that
each with mean/expectation
and variance
We have
so that
Now,
and
We have
because and are independent when , and so
giving a variance of
and so the standard deviation is
# # #
A faster way, assuming you know the variance of a linear combination of independent random variables, is to compute
and since the are independent, each covariance is 0. Then
and take the square root to get the standard deviation.
Answer:
1.a measure, quantity, or frequency, typically one measured against another quantity or measure.
Step-by-step explanation:
2.a fixed price paid or charged for something.
5.35 * 18 = 96.3
Therefore the tennis racket costs $96.3
The answer is y=3x-7, because the initial temperature is -7, and it goes up 3 degrees every hour.
