Answer:

-2

Step-by-step explanation:

To find the slope of a line with 2 given points, you use the formula

m=y2-y1/x2-x1

Now you plug in the points which would be m=3-(-1)/2-4 which equals m=4/-2

4/-2 equals -2

The slope is -2

The number of major faults on a randomly chosen 1 km stretch of highway has a Poisson distribution with mean 1.7. The random var

tiny-mole [99]

The probability can be modeled using the following formula:
$P(X =3)$
wherein X follows the density
$P(X=k)=\frac{1.7^ke^{-1.7}}{k!}$
Now for k = 3 we get:
$P(X=3)=\frac{1.7^3e^{-1.7}}{3!}=0.15$
The probability we are looking for is 0.15.

Help. Please. I need help.

Answer:

C) 3x+20 < 50

Step-by-step explanation:

Since 50 is the limit as to what Mary wants to spend, the number on the left side should never be over 50, meaning that the total will be 'less' than 50

The 20 comes from how much she wants, meaning that 3x would be less than 10 dollars a gift.

Answer:

Both questions are inaccurate.

Step-by-step explanation:

You cannot have a +- next to each other without a number on the right of it.

Also 2-2=0 not 4.
