Answer:
Let's begin with a 30°-60°-90° triangle. A 30°-60°-90° triangle with a hypotenuse of 2 um
Step-by-step explanation:
120 has the same value as 12 tens
Let the time he spent bicycling at 11 mph be x and the time spent bicycling at 15 mph be y, then
x + y = 60 . . . (1)
7x + 11.75y = 600 . . . (2)
(2) x 7 => 7x + 7y = 420 . . . (3)
(2) - (3) => 4.75y = 180
y = 180 / 4.75 = 38
x = 60 - 38 = 22
Therefore, he should bicycle 22 minutes at 11 mph and 38 minutes at 15 mph.
Hi there!
The answer is true.
Conditional Probability does refer to the probability of one event, given that another event has occurred.
For example, you could have picked a marble, and then picked another marble from the same jar. The color of the second marble picked would have been effected by conditional probability, increasing or decreasing probabilities of different colors of marbles being picked because of the removage of the first marble.
Hope this helps!
(6x^-2)^2 * (0.5x)^4
= 36x^-4 * 0.0625x^4
= 2.25 * x^4/x^4
= 2.25 Answer
