Factor the following equations to find the zeros of the equation.

irina1246 [14]

The zeroes of the equation are (1,4)

Step-by-step explanation:

Given equation is:

$y = x^2 - 5x + 4$

We have to put y=0 in the equation to find zeroes of the equation

$x^2-5x+4 = 0\\x^2 - 4x- x +4 = 0\\x(x-4)-1(x-4) = 0\\(x-4)(x-1) = 0\\x - 4 =0 => x = 4\\x-1 = 0 => x = 1$

Hence,

The zeroes of the equation are (1,4)

Sketch the area under the standard normal curve over the indicated interval and find the specified area. (Round your answer to f

Angelina_Jolie [31]

Answer:

$P(z>1.51) =1-P(Z$

And i fwe look into the normalstandar dtable we can find the desired probability:

$P(z>1.51) =1-P(Z$

And then the The area to the right of z = 1.51 is 0.0655

Step-by-step explanation:

For this case we want to find the following probability:

$P(z>1.51)$

And for this case we can use the normal standard distribution and the complement rule and we have this:

$P(z>1.51) =1-P(Z$

And i fwe look into the normalstandar dtable we can find the desired probability:

$P(z>1.51) =1-P(Z$

And then the The area to the right of z = 1.51 is 0.0655
