Answer:
P(draw a blue or red marble) =
Step-by-step explanation:
The bag contains 8 blue, 5 green, and 8 red marbles
Total number of marbles is 8 + 5 + 8 = 21
P(draw a blue or red marble) = P(blue marble) or P(red marble)
In probability,"Or" means addition (+)
So, P(draw a blue or red marble) = P(blue marble) + P(red marble)
P(draw a blue or red marble) = + =
P(draw a blue or red marble) =
Answer:
D. -/8
Step-by-step explanation:
Draw a right triangle such that cos (theta) = 8/9. That means the hypotenuse = 9 and the adjacent side to theta = 8
Use the Pythagorean theorem to find the opposite side to theta
tan (theta) = /8
Since theta is in quadrant IV, the tan is negative. So, tan (theta) = -/8
Answer:
By virtue of The pythagorean theorem,in a right triangle squares of the similar two sides equal the square of The largest side.Only 9,12 and 15 fit this rule.
