we are given
Firstly , we can distribute tan^2 inside
we get
now, we can simplify it
we know that
tan=1/cot
so, tan^2 will get cancelled with cot^2
so, option-C..............Answer
Answer:
3/4 x
Step-by-step explanation:
The rise is 3 and the run is 4, making the slope 3/4 x
So the fisrt thing we need to calculate is that 9 times out of 10 is 90% which will be the confidence interval.
<span>Margin of error is 6% = .06 </span>
<span>Confidence interval is 80 +/- .06 = .74 to .86. or 74% to 86$ </span>
<span>In 9 times out of 10 the confidence interval for similar samples of seniors will contain the </span><span>true mean of the population of senior scores. </span>
I'm not gonna give the answer because you have to solve it. Sorry. But I'll help you get it.
Step 1: solve the equation for each angle
Step 2: Add the totals from each angle
Step 3: Divide the total by 360
Step 4: You got your answer
I hope this helped! I'm sorry I answered really late.
