Answer:
This polygon is comprised of 30 congruent triangles, each with a central angle of 12°
And using trig, each has an area of......
(1/2)(20)^2 sin(12°) = 41.5823381636 sq ft
So, 30 times this = 1247.470144908 sq ft = 1247.5 sq ft (rounded to the nearest tenth)
So approximately 14.5% of the scores are higher than 600. This means in a sample of 7500, one could expect to see
scores above 600.
Answer:
39
Step-by-step explanation:
The angles are equal. This means that the triangle is equilateral and all the sides are equal to each other.
Set any two sides equal to each other.
2x - 3 = x + 5
x - 3 = 5
x = 8
Now substitute this x value into all the sides and add the numbers up.
2(8) - 3 = 16 - 3 = 13
So we know all 3 sides equal 13.
13 * 3 = 39
Answer:
the probability that it is not a drama movie is 15/23
Step-by-step explanation:
To calculate the probability we have to make the number of favorable events divided the number of possible events
number of possible events = x
to calculate it we add all the movies
x = 10 + 5 + 8
x = 23
number of favorable events = y
to calculate it we subtract the drama movies from the total of movies
y = x - 8
y = 23 - 8
y = 15
now we divide 15 by 23 and we get the probability
15/23
It’s B because m is smaller than cm
