It would be 0.17 because 7 is higher than 6 and you would add 1 to the 6.
remember this saying...
5 or more add 1 more 4 or less just ignore
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 .
There are 206 miles left to drive so Tammi would be driving.
<h3>How to determine the total miles left on the trip</h3>
In order to determine the miles left to drive, the sum of the total miles driven have to be determined. This figure would be subtracted from the total miles of the trip.
x = total miles of the tip - sum of miles already driven
Sum of miles already driven = 198 + 189 + 105 + 202 = 694
x = 900 - 694 = 206 miles

Step-by-step explanation:
I had to read this about 5 times in order to understand what it was asking xD!!
It's just asking "how many times do you multiply 10 to get 10^12, divide that by 2, then multiply that by 10".
12 divided by 2 multiplied by 10
6 multiplied by 10
60 dB
I'm not positive, but I believe it's 60 dB
