Henry slept for 10 and a half hours
Answer:
30
Step-by-step explanation:
Solve for n: 0.22n = 6.6.
- 6.6/0.22 (because for example 3/3 and n/n= 1 so 0.22/0.22 = 1 so we have to divide 6.6 since it is part of the equation and we have to do it on both sides.)
- =30

Answer:
c
Step-by-step explanation:
the function (x) = -3x+2 can be obtained by :
* stretching the function (x)=x in the y-axis by 3 units gives 3x
* then reflecting about x-axis gives -3x
* finally shifting it up by 2 units gives -3x+2
so the parent function is f(x) = x
Answer:
There is not enough evidence to support the claim that Alaska had a lower proportion of identity theft than 23%.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 1432
p = 23% = 0.23
Alpha, α = 0.05
Number of theft complaints , x = 321
First, we design the null and the alternate hypothesis
This is a one-tailed test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from the table.
P-value = 0.298
Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.
Conclusion:
Thus, there is not enough evidence to support the claim that Alaska had a lower proportion of identity theft than 23%.
