Answer: the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight = 4.23
Step-by-step explanation:
Formula for margin of error : 
, where z* = Critical z-value.
Given: population standard deviation = 11.5 ounces
Sample size = 20
Z value for 90% confidence level = 1.645
margin of error (E) = 
Hence, the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight = 4.23
The answer is D because 42 / 6 = 7 and the power ( ^X) can cancel out each other
Answer:
Step-by-step explanation:
Surface area of a cylinder:
S. A. = 2πrh + 2πr²
Volume of a cylinder:
V = πr²h
~~~~~~~~~~~
2(π)(2.5)(x) + 2(π)(2.5)² = π(2.5)²(x)
5x + 12.5 = 6.25x
1.25x = 12.5
x = 10
1. For each triangle, multiply the length by the hight then divide by two to find the areas of each triangle.
2. Add the 4 areas together to get the area of the window
3. Divide the sum of those 4 areas by 100 to get the area in metres as opposed to centimetres
If you're looking for the interest the answer would be:
i=8,000*.015*3
i=360.
The interest would be $360 dollars.
The balance would be 8,000+360= $8,360
