A rational number is a number, which can be expressed as a fraction. Since 3 can be expressed as 3=31=62=124 and so on, it is a rational number
Answer:
1.2
Step-by-step explanation:
Given that X is Normally distributed random variable with an unknown mean μ and known standard deviation 6
Hence we can say for a sample of size 100, the sample mean will have a std deviation of =
Since population std deviation is known we can use Z critical value for finding out the confidence interval
For 95% using (68-95-99.7 rules) we have z critical value =2
Hence margin of error =2(std error) = 1.2
Confidence interval 95%
Lower bound = Mean - margin of error = Mean -1.2
UPper bound = Mean +1.2
Hence , 95% of all of these values of x should lie within a distance of __1.2___ from μ .
(2(3))^2 + 5
2(3) = 6
6^2 = 36
36+5 = 41
Answer: 41
Answer:
none of the above (see explanation below)
Step-by-step explanation:
The graph is of the inequalities ...
- y > 1 . . . . . . . more than 1 copy is required per tour
- y ≥ 2x . . . . . the number of copies must be at least double the number of confirmed parties
_____
The graph shows the number of copies as a continuous variable with a value greater than 1. If you assume it must be an integer, then its minimum value is 2, and you might say ...
○ at least two copies are required per tour
__
This is not the same as "more than 1 copy is required." (y > 1 is not the same as y ≥ 2)
Answer: B
Function 2's rate of change is 3/2, and Fuction 1's rate of change is 2/5
3/2 is bigger than 2/5
Proof:
3/2 (3 ÷ 2) = 1.5
2/5 (2 ÷ 5)= 0.4
