When the black chip is drawn, there is already one less chip in the bag; keep this in mind..
the probability of getting a black chip out of the bag is 10/25 or 2/5
now since there is one less chip, there is a total of 24 chips now..
so now the probability of getting a red chip is 5/24
then you would multiply the two events together and get:
2/5 x 5/24....solve
42. The mean is the total of the numbers divided by the amount of numbers. In this case the amount of numbers is 7 and the mean is 6. That means that the total of the numbers divided by 7 equals 6. To find the total you just do the opposite, multiply 7 by 6 and you get 42.
Answer:
x = 168.75°
Step-by-step explanation:
<u>Angle Measurement Units</u>
To convert from different units for angle measurements, we have to recall that:
180 degrees = π radians
If we are given the angle in degrees, multiply by π/180 to convert it to radians.
If the angle is given in radians, multiply by 180/π to convert to degrees.
We are given the angle:

Multiplying by 180/π:

Simplifying:

x = 168.75°
Step-by-step explanation:
125cm = 1.25m.
2m : 1.25m = 8:5
That is too small to be an improper fraction.
