Answer:

Check explanation

Step-by-step explanation:

I think that you might be missing a negative in one of your values because it comes out to 0 if you put both y's as 1...

m = (y2 - y1) / (x2 - x1)

m = (1 - 1) / (2 - (-4) )

m = 0 / 6

m = 0

but if one of the ones is negative then it would be

m = (y2 - y1) / (x2 - x1)

m = (1 - (-1)) / (2 - (-4) )

m = 2 / 6

m = 1 / 3

According to a study done by a university student, the probability a randomly selected individual will not cover his or her mou

Margarita [4]

Answer:

a. P(X=8)=0.0277

b. P(X<4)=0.3460

c. No. P(X<8)=0.9605

Step-by-step explanation:

a. Let x denote the event.

This is a binomial probability distribution problem expressed as

$P(X=x)={n\choose x}p^x(1-p)^{n-x}$

Where

n is the total number of events
p is the probability of a success
x is the number of successful events.

Given that n=16, p=0.267, the probability of exactly 8 people not covering their mouths is calculated as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\\\P(X=8)={16\choose 8}0.267^8(1-0.267)^8\\\\\\=0.0277$

Hence, the probability of exactly 8 people not covering their mouths is 0.0277

b. The probability of fewer than 4 people covering their mouths is calculated as:

-We calculate and sum the probabilities of exactly 0 to exactly 3:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X$

Hence, the probability of x<4 is 0.3460

c. Would you be surprised if fewer than half covered their mouths:

The probability of fewer than half covering their mouths is calculated as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X$

No. The probability of fewer than half is 0.9605 or 96.05%. This a particularly high probability that erases any chance of doubt or surprise.

Solve x^2+2x+1=0 by graphing

klio [65]

Solutions are − 1 ,2 and postive 2 and 1 /2 Explanation: When we draw graph of y = x 2 − 2 x − 1 , as a point on x -axis means y = 0 , intercepts on x -axis, give the solution of equation x 2 − 2 x − 1 = 0 Now, if x = 2 , y = − 1 if x = 0 , y = − 1 if x = − 2 , y = 7 if x = 1 , y = − 2 if x = 3 , y = 2 and if x = − 3 , y = 14 So joining points { ( 2 , − 1 ) , ( 0 , − 1 ) , ( − 2 , 7 ) , ( 1 , − 2 ) , ( 3 , 2 ) , ( − 3 , 14 ) } we get the graph graph{x^2-2x-1 [-10, 10, -5, 5]} It shows that intercepts on x -axis are − 1 2 and 2 1 2 Hence, these are the solutions.
