I’m geussing the answer would be A because an ordered pair of that is (2,8) but the only difference is it’s negative so A hope this helps

Call a household prosperous if its income exceeds $100,000. Call the household educated if the householder completed college. Se

melisa1 [442]

Answer: 0.317

Step-by-step explanation:

Let A be the event that the selected household is prosperous and B the event that it is educated.

Given : P(A)=0.138, P(B)=0.261

P(A and B)=0.082

We know that for any events M and N ,

$\text{P(M or N)=P(M)+P(N)-P(M or N)}$

Thus , $\text{P(A or B)=P(A)+P(B)-P(A or B)}$

$\text{P(A or B)}=0.138+0.261-0.082\\\\\Rightarrow\text{ P(A or B)}=0.317$

Hence, the probability P(A or B) that the household selected is either prosperous or educated = 0.317

The line y=-1/3x+4 passes through which of the following points

e-lub [12.9K]

Answer:

The line passes through the points ( 0 , 4 ) and ( 12 , 0 )

Step-by-step explanation:

Given equation of line as :

y = - $\frac{1}{3}$ x + 4

Let the points through which the line passes are

( $x_1$ , $y_1$ ) , ( $x_2$ , $y_2$ )

Now, for x = 0 , The line equation is y = - $\frac{1}{3}$ × 0 + 4

I.e for x = 0 , y = 0 + 4 = 4

So, ( $x_1$ , $y_1$ ) = ( 0 , 4 )

Again , for y = 0 , The line equation is 0 = - $\frac{1}{3}$ × x + 4

I.e for y = 0 , The line equation is 4 = $\frac{x}{3}$

Or, for y = 0 , x = 4 × 3 = 12

So , ( $x_2$ , $y_2$ ) = ( 12 , 0 )

Hence The line passes through the points ( 0 , 4 ) and ( 12 , 0 ) Answer

The width of a rectangle is 3 3 feet longer than two times its length, and its area is 27 27 . If you use L L to represent the l

Nady [450]

Answer:

The expression representing the width is 3+2L

The width is 9ft

Step-by-step explanation:

Area of a rectangle = Length×width

A = L × W...(1)

Let the length be represented as L

Since the width of the rectangle is 3feet longer than two times its length, this is expressed as:

First, width is twice as long as the length i.e W = 2L

If the resulting width is now 3 feet longer, the final width of the rectangle will be expressed as:

W = 3+2L...(2)

Area (A) = 27ft

Substituting equation 2 into 1, we have;

A = L(3+2L)

A = 3L+2L²

27 = 3L+2L²

2L²+3L-27 = 0

Factorizing the resulting equation

(2L²+9L)-(6L-27) = 0

L(2L+9)-3(2L+9) = 0

L-3 = 0 and 2L+9 = 0

L = 3 and L = -9/2

Disregarding the negative value and substituting L = 3 into equation 2 to get the width

W = 3+2(3)

W = 3+6

W = 9ft
