<span>Slope-intercept form is y = mx + b
m is the slope
b is the y-intercept
7x = 14y - 8
7x + 8 = 14y {added 8 to each side}
(1/2)x + (8/14) = y
slope is 1/2
A line perpendicular would have a slope of -2 {the negative reciprocal of 1/2}
#1 y = -2x - 7 {it is the only one with a slope of -2}</span>

Answer:
1000000000000
Step-by-step explanation:
2000^6/8000^2=1000000000000
A. Frank has 24 marbles. I found this because Dan has 15 and total is 63 so subtract 63-15= 48. 48 divided by 2 people, which are Ellie ans Dan is 24. Dan has 24 marbles.
Answer:
The correct answer is option 'a' : 120 is more than 2.5 standard deviations above the expected value.
Step-by-step explanation:
For an exponential distribution we have
The expected value μ = 80
No of trails n = 200
Thus we have

The deviation is related to expected value and probability as

Thus the values between the given deviation is

Now since 120 successes are out of the range of [62.75,97.25] thus 120 is more than the expected value.
