If you are giving a line that crosses 2 parallel lines, angle 3, 4 and 5 are 52.6 as well because they are all complementary to each other, and angles 1, 2, 7 and 8 are all 127.4 degrees because 180 degrees from one side to the other on the line minus 52.6 from the other side leaves 127.4 degrees in the other angles.
So for the Area you would do Length x width, for a square the length and width are equal so if you take the square root of 1/16 you get 1/4
Answer:
205.667
Step-by-step explanation:
4 71/2+2 3/4+7 5/12+ 13 3/4 +14 1/4+ 14 3/4+ 15 1/4=205.667
G (x) = -11/4 ...
that's your answer
Answer:
- P(x < 84) = 0.3085 or approximately 31%

<em>Hello to you from Brainly team!</em>
<h3>Given</h3>
- Mean grade μ = 86,
- Standard deviation σ = 4,
- Grade limit x = 84.
<h3>To find </h3>
- Probability of that a randomly selected grade is less than 84 or P(x < 84).
<h3>Solution</h3>
Find z-score using relevant equation:
Substitute values and calculate:
Using the z-score table find the corresponding P- value.
- P(x < 84) = 0.30854 or approximately 31%
