Choices A, C, and D don't make sense since they are not three-dimensional. Surface area deals with 3D shapes, not 2D.
Answer:
Step-by-step explanation:
2x + 6
Answer:
b
Step-by-step explanation:
We must determine the the x value at 90% confidence interval. We find this from a table relating confidence intervals and x values. For 90%, z is 1.645.
WE must determine the mean of 19 and 23:
We must determine the standard deviation. We let n be the number of population which is 2. We need to take the numbers 19 and 23 and subtract each by the mean and square the answer:
We then determine the mean of these two values as:
Now we take the square root of 365:
The standard deviation is 19.1
The answer is b
For every other number, you multiply by 2 and then add 3.
2 x 2 is 4, then 4 + 3 is 7, then 7 x 2 is 14, then 14 + 3 is 17...
