<em>Complete Question:</em>
<em>The function shown models the depth d (in inches) of snow on the ground during the first 9 hours of a snowstorm, where t is the time (in hours) after the snowstorm begins.
</em>
<em>
The -intercept means that there were[ ]inch(es) of snow on the ground at the start of the storm and the slope means that[ ]inch(es) of snow falls every hour during the storm.
</em>
<em>Function: d(t)= 1/2t+6</em>

Answer:
62
Step-by-step explanation:
There are two lengths so 77 + 77 is 154. Now, subtract from the perimeter. 278 minus 154 is 124. This is both widths combined so to only get one, divide by 2. 124 divided by 2 is 62.
Answer:
sigma should be used
Step-by-step explanation:
Given that The mean length of time in jail from the survey was four years with a standard deviation of 1.9 years.
The above given is for sample of 27 size.
For hypothesis test to compare mean of sample with population we can use either population std dev or sample std dev.
But once population std deviation is given, we use only that as that would be more reliable.
So here we can use population std deviation 1.4 only.
If population std deviation is used we can use normality and do Z test
