Answer:
Probability of having an accident = 20% o 0.2
Thus,
Expected number of years = 1/probability of accident = 1/0.2 = 5
Hence,
3. Every 5 years is the correct option.
Step-by-step explanation:
Angle Y would be 40 degrees
Answer:
60:150
Step-by-step explanation:
So first you can divide 210 by 7 since it will be spilt into seven parts.
210/7 = 30
So in order to get them into the ratios:
30 x 2 = 60
30 x 5 = 150
So 210 in the ratio of 2:5 would be 60:150
You can check your work by adding 60 + 150 together.
X is approximately 62.23 units
Separate the square into two right triangles. Since all 4 sides of the square are congruent (equal to each other), they are all 44 units long. The Pythagorean Theorem is a^2 + b^2 = c^2, where a and b are sides of the triangle and c is the hypotenuse (longest side of the right triangle, in this case would be x).
44^2 + 44^2 = c^2
1936 + 1936 = c^2
3872 = c^2
Take the square root of both sides.
c is about 62.23
c = x, so x is around 62.23 units long
Hope this helps
Answer:
True
Step-by-step explanation:
Yo find the midpoint between 2 points x1 and x2
midpoint = (x1+x2)/2
midpoint = (-7+8)/2
midpoint = 1/2
