Answer:
8
Step-by-step explanation:
I knew that 6 bigger than 50 is 56 and if the number is multiplied by 7 then you just do 56 divided by 7 and you get 8. So the number is 8 hope this helps :))
The answer is 6 positive tiles.
Answer:
Step-by-step explanation:
The mean (or average) of a set of numbers can be found with the following formula:
For this problem, we have five numbers, so we add them together and divide by 5:
Answer: option 1
Step-by-step explanation: By constructing a 99% confidence interval for population proportion, it implies that the principal is 99% sure that the confidence interval will contain the population proportion.
When we construct confidence interval, we do so to show that the population parameter that we are looking for is present in the interval at a specified confidence level.
(tan(<em>x</em>) + cot(<em>x</em>)) / (tan(<em>x</em>) - cot(<em>x</em>)) = (tan²(<em>x</em>) + 1) / (tan²(<em>x</em>) - 1)
… = (sin²(<em>x</em>) + cos²(<em>x</em>)) / (sin²(<em>x</em>) - cos²(<em>x</em>))
… = -1/cos(2<em>x</em>)
Then as <em>x</em> approaches <em>π</em>/2, the limit is -1/cos(2•<em>π</em>/2) = -sec(<em>π</em>) = 1.
