Answer:
k = 77/10
Step-by-step explanation:
The jar consist of blue, red and green marbles . The probability of each of them can be described as follows.
probability of blue marbles = 2/7
probability of red marbles = 3/k
probability of green marbles = 5/2k
The sum of the individual probability is equals to 1. Therefore,
2/7 + 3/k + 5/2k = 1
collect like terms
(6 + 5)/2k = 1 - 2/7
11/2k =(7 - 2) /7
11/2k = 5/7
cross multiply
10k = 77
divide both sides by 10
k = 77/10
Y - y1 = m(x - x1)
slope(m) = -3/4
(2,-6)...x1 = 2 and y1 = -6
now we sub...pay close attention to ur signs
y - (-6) = -3/4(x - 2)...not done yet
y + 6 = -3/4(x - 2) <===

Step-by-step explanation:
The sine of an angle is equal to the cosine of that angle minus 90 degrees, and vice versa. Since 65=90-25, the cosine of 25 is equal to the sin of 65. If this is unclear please PM me or comment, and I can help more!
