Answer:
inches.
Step-by-step explanation:
The level of a lake was 8 inches below normal.
Now, it is given that the water level decreases inches in June and
inches more in July.
Therefore, the new level of water with respect to the normal level will be
= - 8 - 1.25 - 2.375
= - 9.625 inches
= inches. (Answer)
Answer:
26
Step-by-step explanation:
The formula should be
s=2
r
If 90 inches is the full diameter, cutting it by half will give you the radius, then you just plug in everything else.
*2*
*45= 26
inches
This answer is better to leave it as pie, so multiply everything else besides the pie.
The 90% confidence interval for the population mean of the considered population from the given sample data is given by: Option C: [130.10, 143.90]
<h3>Suppose that we have:
Then the confidence interval is obtained as
For this case, we're given that:
At this level of significance, the critical value of Z is: = ±1.645
Thus, we get:
Thus, the 90% confidence interval for the population mean of the considered population from the given sample data is given by: Option C: [130.10, 143.90]
