Brainliest pleeease!!!!
Ok sooooooo the line is at the y intercept at (0,-50)
And if u choose two points on the graph (solid points) likeeee…. (0,-50) and (20,-30)
Use rise/ run
Soooo u go up two units and right two units soooo 2/2!!! Simplified thats what?? Thats 1!!
And so.
Y=mx+b
Plug in a few numbers….
Y=1x-50
Aaaaand the slope is moooving up (how do I know??) because from the start which is (0,-50) it goes up. So that’s why the 1 is positive. It’d be negative if it’s going the other way.
Sorry if that made no sense but moral of the story, the answer is y=1x-50

50/-100 that would be the answer I’m not sure

Answer:

$p(x\geq 1)=0.1975$

Step-by-step explanation:

the probability that x iPads are defective in the sample follows a hypergeometric distribution, so it is calculated as:

$p(x)=\frac{kCx*((N-k)C(n-x))}{NCn}$

Where $aCb=\frac{a!}{b!(a-b)!}$

Because we have a N elements with k elements that are defective and we are going to take a sample of n elements. So, replacing N by 100, k by 7 and n by 3, we get:

$p(x)=\frac{7Cx*((100-7)C(3-x))}{100C3}$
