The answer for the value of x is 27 degrees.
you can find this since the triangle is a right triangle, so the one undetermined side is 90 degrees.
90+63=153 degrees.
a triangle has 180 degrees.
therefore, 180-153=27 degrees

Answer:
0.97725
Step-by-step explanation:
Given that Professor Heinz has given the same multiple-choice final exam in his Principles of Microeconomics class for many years. After examining his records from the past 10 years, he finds that the scores have a mean of 76 and a standard deviation of 12.
i.e.
Std error of mean = sigma/sqrt n = 2
Thus the sample mean is N(76,2)
Required probability = probability that a class of 36 students will have an average greater than 72 on Professor Heinz's final exam.

Hi there!
Reduced means "to simplify".
66/42=1 4/7.
66÷6=11 and 42÷6=7.
Therefore, 11/7=1 4/7.
So, 66/42 reduced is 1 4/7.
Hoped I helped. :)
Answer:
24.2 marks
Step-by-step explanation:
25 + 36 + 20 + 15 + 24 + 30 + 38 + 32 + 22 = 242
since there are 10 students we divide 242 by 10 and get 24.2
To find the length of the arc, we will use the formula,
arc length = 2πR (C/360)
where,
R is the radius of the arc, which is 8"C is the central angle, which is 45°
pi is approximately equivalent to 3.14
Applying the formula,arc length = 2πR (C/360)
arc length = 2(3.14)R (45°/360)
arc length = (6.28)(8") x (0.125)
arc length = (50.24") (0.125)
arc length = 6.28"
The length of the arc is 6.28". 6.28 is also equivalent to 2π, hence, the answer is 2π.
