Answer:
The correct option is C) Both of the above.
Step-by-step explanation:
Consider the provided statement.
First understand the meaning of Confidence level.
Confidence level refers to the percentage of likelihood, or assurance, that when you draw a random sample several times, the confidence interval will contain the true population variable.
99% confidence means We are 99% sure that most of these confidence intervals contain the true parameter of the population.
Therefore, both the statement are correct.
Hence, the correct option is C) Both of the above.
Answer:
0.98
Step-by-step explanation:
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.13 + 0.85 - 0
P(A or B) = 0.98
Note that P(A and B) is 0. This is because we are told A and B are mutually exclusive events. This means both events cannot happen simultaneously. An example would be flipping a coin to have it land on heads and tails at the same time.
4.6 because -3.2+1.4=4.6 negative +positive = positive
5220 is your answer
please can i have a brainliest
Expanded form is when you just write it out.
so 9 cubed becomes:
9×9×9
and 20 squared becomes:
20×20
the exponent tells you how many times to multiply that number by itself. so, whenever it asks for expanded form, you just write the number how ever many times the exponent tells you to and multiply them all.
