Answer:
The standard deviation is not greater than 5 mg ()
Step-by-step explanation:
First we need to find the z-score for a 0.05 level of significance.
Looking in the z-table with alpha = 0.05, we have z = 1.645.
Now, finding the standard error of the mean, we have:
The standard deviation with 0.05 level of significance would be:
This deviation is not greater than 5 mg.
250 and - 1250
This is a geometric sequence with common ratio r = - 5
multiply each term by - 5 to obtain the next term
- 50 × - 5 = 250
250 × - 5 = - 1250
the sequence is - 2, 10, - 50, 250, - 1250
The answer is the first one.

Answer:
bottom: 12 x 12 = 144
1st triangle: (12 x 8)/2 = 48
2nd triangle: 48
3rd triangle: 48
4th triangle: 48
144 + 48 + 48 + 48 + 48 = <u>336 cm squared</u>
