Here's the key to unlock the whole problem and make it crumble in a pile of dust at your feet:. A tangent is perpendicular to the radius at the point where the tangent touches the circle. /// Connect point O to the point way outside, and you have two congruent right triangles face to face. The angles inside each one add up to 180. Each angle at O is half of 134, and each angle at the point way outside is half of 'x'. I bet you can do it now.

To find the critical value
that corresponds<span> to 97% confidence level</span>:
Step 1:
Subtract 0.97 from 1:
1 - 0.97 = 0.03
Step 2:
Divide 0.03 by 2:
0.03 / 2 = 0.015
Step 3:
Subtract 0.03 from 1:
1 - 0.015 = 0.985
Step 4:
From the normal distribution table, the z score that corresponds to a probability of 0.985 is 2.17.
Therefore, <span>the critical value that corresponds to 97% confidence level is 2.17.</span>
Answer:
x = s/2
Step-by-step explanation:
● s states have joined the union in 1788
● half of s have joined in 1889
Let x be the number of states that have joined in 1889
● x = (1/2)× s
● x = s/2
15% markup on $17,000 = 17000*.15=$2550
25% markup on $4,000 = 4000*.25 = $1000
now just add the two markups.
