Answer:
0.674
Step-by-step explanation:
If the random variable X is exponentially distributed and X has an average value of 25 minutes, then its probability density function (PDF) is
and its cumulative distribution function (CDF) is
So, <em>the probability that X is less than 28 minutes is
</em>
Answer:
x = 23.5
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 54 = x / 29
29 sin 54 = x
x=23.46149
To the nearest tenth
x = 23.5
#5: This is a function. It passes the vertical line test.
#6: This is not a function. It does not pass the vertical line test. For example, x=0 has six y-values paired with that one x-value. A function that does not make.
#7: This passes the vertical line test.
Step-by-step explanation:
(2x_5)(x+4)
2x(x+4)_5(x+4)
2x²+8x_5x_20
2x²+3x_20=3x+30
2x²+3x_3x=30+20
2x²=50
√2x²=√50
2x=7.071
2x/2=7.071/2
ans=3.536
