Answer:
D
Step-by-step explanation:
Lets start by figuring out the vertex. From looking at the picture, you can tell that the vertex (the place where the line thingy stops going down and starts going up) is (-3 , -1).
Now, these equations are set up like this: y2 = h*(x2 - x1) + y1
(-3 , -1) is the same thing as saying (x1 , y1)
So, this rules out A, B, and C
Therefore, your answer is D! :D
I think you need to divide first then yea blah blah
<span>I believe you use the exponential distribution to find the probability of success (say "p"). Then, you use the Geometric(p) distribution using the "p" you calculated from the exponential as your success probability. Also, in b), you use a negative binomial (which is really just a generalized geometric distribution).
</span><span>Part c) Find the probability to 2 decimal places that the first success occurs in an odd-numbered observation. That is, the first success occurs in the 1st or 3rd or 5th or 7th (and so on) observation.</span>
Answer:
The equation is y = -2/5x + 4
Step-by-step explanation:
First we have to find the slope of the line. In order to do so, solve the first equation for y.
2x + 5y = 20
5y = -2x + 20
y = -2/5x + 4
This gives us a slope of -2/5. Given that information, we now can plug the slope and point into point-slope form and get the final equation.
y - y1 = m(x - x1)
y - 6 = -2/5(x - -5)
y - 6 = -2/5(x + 5)
y - 6 = -2/5x - 2
y = -2/5x + 4
Answer:
-6, -7
Step-by-step explanation:
basically
-4 5/8 - x >0
so
x< -4 5/8
you just need 2 values less than -4 5/8
like -6 and -7
