Write an equation of a line parallel to y = -2x + 3 that passes through (-2,-1)

ElenaW [278]

$\boxed{y=-2x-5}$

<h2>Explanation:</h2>

The slope-intercept form of the equation of a line:

$y=mx+b \\ \\ \\ Where: \\ \\ m:Slope \\ \\ b:y-intercept$

The given line has the following characteristics:

$y=-2x+3 \\ \\ \\ So: \\ \\ m=-3 \\ \\ b=3$

So the line we are looking for needs to be:

$y=-2x+b \\ \\ \\ It \ passes \ through \ (-2,-1): \\ \\ -1=-2(-2)+b \\ \\ b=-1-4 \\ \\ b=-5$

So, the equation of the line would be:

$\boxed{y=-2x+3}$

It is known that 10% of the calculators shipped from a particular factory are defective. In a random sample of ten calculators,

umka2103 [35]

Answer:

0.7361

Step-by-step explanation:

In this question we have

number to be 10

Then we have a probability of 10% = 0.10

We have q = 1-p

= 1-0.10 = 0.90

Then the probability of not more than 1 being defective:

P(x=0) + p(x= 1)

(10C0 x 0.1⁰ x 0.9^10-0)+(10C1 x 0.1¹ x 0.9^10-1)

= 1 x1 x0.3487 + 10 x 0.1 x 0.3874

= 0.3487 + 0.3874

= 0.7361

This is the the required probability and this answers the question.

probability = 10 percent = 0.1

q= 1- 10percent = 90% = 0.9

n = 4

To get the required probabiltiy for this question is

P(not greater than one is defective )=P(x=0)+P(x=1)

= 4C0x(0.1)⁰x(0.9)⁴+4C1x(0.1)¹x(0.9)³

= 0.9477

The required probability is 0.9477

How to solve this geometry?<br> Step by step solution please.

Dahasolnce [82]

This is a relatively complex problem and it took me a good 20 minutes to solve, I included a sketch I made myself while im solving this problem hope it helps with the explanation. (the dotted lines are my drawings, also I labeled the points just look at my graph)

Now to find <x, we can use the exterior angles theorem a couple of times.

<x=<p+<AGE

<x=30 degrees + <AGE

Now use the theorem again to find <AGE

<AGE=<q+<BIG

Now use substitution for <q and for <AGE

<x=30 degrees+60 degrees+ <BIG

We put this to the side for now and try solve for <CHD which is not very difficult

<CHD=180-45-20=115

We can also clearly figure out <HFI using vertical angles theorem.

<HFI=<Y

Because they all form a triangle we can conclude that <y+<BIG=180 degrees-<FHI= 180-115=65 degrees

substitution again

<x+<y=30+60+<BIG+<HFI (remember <HFI = <y vertical angles theorem)

<x+<y=30+60+65 (remember how we did before these 2 angles adds up to 65?)

<x+<y=155 degrees

Now please don't hate me on this, I'm sure there is more efficient ways to explain this problem, this is just my way from trial and error.

<u>Tip for next time you are stuck on a geometry problem, don't be afraid to draw the graph again on paper and add lines to it!</u>

<u>You won't get everything perfect the first time you try but the more you practice the more comfortable you are with these problems, Hope my explanation helped!</u>

<u></u>

**Just a note would you mind telling me where you got this problem form, its pretty challenging :)
