Answer:

Its Option C.

Step-by-step explanation:

-4x + 7 = 2y - 3

Substitute the given values in the  given equation:-

(2,1):-    -4(2) + 7 = -1  and 2(1) - 3 = -1  so (2,1) is a solution.

(5, -5):-  -4(5) + 7 = -13 and 2(-5) - 3 = -13  so (5, -5) is also a solution.

Let E be the event that a corn crop has an infestation of ear worms, and let B be the event that a corn crop has an infestation
KatRina [158]

Answer:

The probability that a corn crop has either an ear worm infestation, a corn borer infestation

P(EUB) = 0.27

Step-by-step explanation:

<u>Explanation</u>:-

<u>Addition theorem on probability</u>:-

If S is a sample space, and E , F are any events in S then

P(EUF) = P(E) +P(F) -P(E n F)

Let 'E' be the event that a corn crop has an infestation of ear worms

let 'B' be the event that a corn crop has an infestation of corn bores

P(EUB) = P(E) +P(B) -P(E n B)

given P(E) = 0.24 and P(B) = 0.16 and P(E n B) =0.13

P(EUB) = P(E) +P(B) -P(E n B)

P(EUB) = 0.24 + 0.16 - 0.13

           = 0.27

The probability that a corn crop has either an ear worm infestation, a corn borer infestation

P(EUB)=0.27

I need to factor 2x squared plus 6X minus 80
hjlf
2x*2 + 6x + 80

First we have to use distribution property

2(x*2 + 3x + 40)=0
Divide 2 to both sides

X*2 + 3x + 40=0

Multiply -1
-x*2 -3x-40=0
Add two numbers to get 3x
Multiply same two numbers that you add to get 40x*2

Add
-8x+5x= -3x


Multiply
-8x . 5x= -40x*2


-x*2-8x+5x-40

(X*2-8x) + (5x-40)

X(x-8)+ 5(X-8)

Common factor

(X-8)(x+5)

tekilochka [14]

Answer:

The answer is "778"

Step-by-step explanation:

Given value:

\to \mu= 711\\\\\to \sigma= 80\\\\\to P(Z >0.84) = 0.20\\\\\to z = 0.84

The formula for z-score:

\to x = z \times  \sigma + \mu \\\\\to x = 0.84 \times 80 + 711 \\\\ \to x=67.2 +711\\\\ \to x=  778.2\\\\ \to x= 778
