Answer:
True
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:
In which z is related to the confidence level(the higher the confidence level the higher z is), s is related to the standard deviation and n is the size of the sample.
A higher confidence level leads to a larger margin of error, that is, a wider interval. The interval expands around it's lower and upper bounds, which means that if a value is part of a lower confidence interval(such as 95%), it will be part of the higher(such as 99%), and the answer to this question is true.
Answer:
10
Step-by-step explanation:
Use order of Operations - PEMDAS
First, (2x3) = 6
Now you have, 1+6-(-3)
Then take the -(-3) and make it +3, cause a subtraction and negative sign make a positive.
Now you have, 1+6+3
Then add it all together to get 10
A) 60mph
B) 209.7 miles
C) 2 hours and 45 minutes
The answer is 6 i thought it was by looking at it but i did the math just to make sure for you
Answer:
2^-84
Step-by-step explanation:
First simplify inside the parentheses
2^-10 / 4^2
Rewriting 4 as 2^2
2^-10 / 4^2^2
We know that a^b^c = a^(b*c)
2^-10 / 2^(2*2) = 2^-10 / 2^4
We know that a^b / a^c = a^(b-c)
2^-10 / 2^4 = 2^(-10-4) = 2^-14
Replace the term in side the parentheses with 2^-14
2^-14 ^7
We know that a^b^c = a^(b*c)
2^(-14*7)
2^-84
