Answer:

Yes, this is a valid inference because she took a random sample of the neighborhood.

Step-by-step explanation:

As we can see, Sue's survey was perfectly random and without any prejudice.

18% of the families, according to her research, would volunteer at the shelter. According to her, 18% of the local households should be required to volunteer at the animal shelter.

Therefore, given that she chose a representative sample of the area, her conclusion is valid.

kirill115 [55]

Answer:

w=2r

r= w/2

r- w/2 = 0

w -2r= 0

Step-by-step explanation:

Let w be the number of weeks and r be the number of recipes learnt . So he will learn 2 recipes each week .Equating gives

w=2r

when w= 1

w= 2(1) = 2

For 1st week 2 recipes are learned

when w= 2

w= 2( 2) = 4

For 2nd week 4 recipes are learned.

or

when r= 2

r= w/2

r =2/2  = 1  one  recipe is learned in half of the week  

r- w/2 = 0

or

w -2r= 0

Answer:

f^{-1}(x)=x^2+1

Step-by-step explanation:

The inverse of a function is when the x and y are swapped. So the first step is to write f(x) as y and then swap the x and y

Original Equation:

f(x)=\sqrt{x-1}\\

write f(x) as y (since that's what it represents)

y=\sqrt{x-1}

Swap x and y

x=\sqrt{y-1}

Square both sides

x^2=y-1

Add 1 to both sides

x^2+1=y

So this gives you the equation:

f^{-1}(x)=x^2+1

Answer:

The distance between (-4, 3) and (4, 3) is 8

Step-by-step explanation:

Distance:  \sqrt{(4 - (-4)^2 + (3 - 3)^2}

Distance:  \sqrt{(4 + 4)^2 + (0)^2}

Distance:  \sqrt{8^2} \\

Distance:  8

Answer:  The distance between (-4, 3) and (4, 3) is 8
