Answer:

x=-13

Step-by-step explanation:

Which is the best estimate of the correlation coefficient for the scatter plot?
leva [86]

The best estimate for this correlation would be B) 0.9.

We can see that the number is constantly going up, which would throw out the D answer.

We can also see that for every time the x goes up 1, the y goes up a little less than one. We can see that in the ordered pairs that exist on the graph such as (3, 2), (8, 6) and (2.1, 1.9).

Since the y values are just lower than the x, the correlation would be just under one. Therefore, 0.9 is an accurate estimation.

2) Size of each pieces:

=\frac{3}{4} *\frac{1}{3}* \frac{3}{5} *\frac{1}{3}\\= \frac{1}{4} *\frac{1}{5} \\= \frac{1}{20}

3) Area of the shaded rectangle:

=\frac{3}{4} *\frac{3}{5} \\= \frac{9}{20}

You charge $5 plus $0.75 per dog you walk at a dog shelter. You earn $14 total working on a Saturday. How many dogs did you walk
san4es73 [151]

Answer: You walked 12 dogs

Step-by-step explanation:

If you charge 0.75 per dog then we can represent that by the expression 0.75x where x is the number of dogs. If you charge $5 for the initial amount, then the whole expression will be 0.75x +5  and that has to equal the amount that you earned working on Saturday.So the equation will be

0.75x + 5 = 14   Now solve for x by first subtracting 5 from both sides

          -5     -5

0.75x = 9      Divide both sides by 0.75

 x = 12

help with this please
Ierofanga [76]

Answer:

see explanation

Step-by-step explanation:

Under a translation < 5, - 9 >

5 is added to the original x- coordinate and 9 is subtracted from the original y- coordinate, that is

A(1, 4 ) → A'(1 + 5, 4 - 9 ) → A'(6, - 5 )

B(2, - 2 ) → B'(2 + 5, - 2 - 9 ) → B'(7, - 11 )

C(- 3, 2 ) → C'(- 3 + 5, 2 - 9 ) → C'(2, - 7 )
