A#b = 2a(7-b)
(2#5)#3
Let us look at the parentheses first.
2#5 = 2*2(7-5)
= 4(2)
= 8
Now the equation becomes 8#3
8#3 = 2*8(7-3)
=16(4)
= 64
The value is 64. Hope this helps!
The line will represent the graph of the equation y=2.5x-8.
The two points necessary to graph would be (2,-3) and (0,-8).
<h3>
What is the slope-intercept form?</h3>
The slope-intercept form is y=mx+c
If the line passes through (2,-3),
let us plugin and find c.
So we get,



So, The equation of the line is y=2.5x-8.

Answer:
n = - 12
Step-by-step explanation:
Isolate the term in n by subtracting 4 from both sides
= 6 ( multiply both sides by - 2 )
n = 6 × - 2 = - 12
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>
