There are about 20 yellow marbles.
The experimental probability is 5/20, since 5 yellow marbles were drawn out of 20 in the sample.
5/20(80) = 400/20 = 20
Answer:
B
Step-by-step explanation:
Looking at the graph we can see that the function is increasing -4<x<-2 and 0<x2
The graph is increasing when it is going upwards, or has a slope greater than 0
We can see that happening in two places in the function, which are the intervals of the x coordinate in B
The answer to the math probability question you are presenting above would be .475 or (47.5%). The value of 3 years multiplied by 1000 would equal to 3000, thus the person will listen to music 3000 hours a year - which is two standard deviations than the mean. Following the empirical rule, the answer would be .475.
Answer:
(x - 7y)/(x + 3y)
Step-by-step explanation:
x² - 5xy - 14y²
x² - 7xy + 2xy - 14y²
x(x - 7y) + 2y(x - 7y)
(x - 7y)(x + 2y)
x² + 5x + 6y²
x² + 3xy + 2xy + 6y²
x(x + 3y) + 2y(x + 3y)
(x + 3y)(x + 2y)
[(x - 7y)(x + 2y)] ÷ [(x + 3y)(x + 2y)]
(x - 7y)/(x + 3y)
