Answer:
The answer is last option
As we know 1 + tan^2 = sec^2
Answer:
totally last year dude XD
Step-by-step explanation:
Answer:
the figure on the top left
Step-by-step explanation:
Hey There!
If figure a was going to be dilated by a scale factor of 3 you would have to multiply all of its dimensions by 3
the top length would be 6
the bottom length would be 9
the right side length would be 12
and the left side length would be 9
The first figure has all of these dimensions thus it is correct answer
Answer:
Yes
Step-by-step explanation:
When the greatest common factor of two numbers is 1 or -1, the numbers are known as relatively prime. This means there are no numbers that can be factored out of both of the numbers, meaning if the numerator and denominator are relatively prime, they can not be simplified any further.
Answer:
The minimum sample size required is 5,499 computer users.
The major obstacle is that it is a big sample size if it is a small organization wanting to perform it.
Step-by-step explanation:
We need to calculate a sample size in order to have 95% confidence interval with 12 minutes of witdth.
So, we have that the difference between the upper limit and the lower limit is 12:


For a 95% CI, the value of z is 1.96. The standard deviation is 227.

The minimum sample size required is 5,499 computer users.
