Answer:

5x -3y = 44

Step-by-step explanation:

We choose to start with the form ...

(Δy)x -(Δx)y = (Δy)(x1) -(Δx)(y1) . . . . . where Δy = y2 -y1 and Δx = x2 -x1

For this purpose, it is convenient to choose y2 > y1, so we have ...

Δy = -3 -(-8) = 5

Δx = 7 -4 = 3

5x -3y = 5(4) -3(-8)

5x -3y = 44

Jessie finished the first race in 2 minutes 7 seconds tim finished 12 seconds faster then Jessie Juan finished 8 seconds faster

xxMikexx [17]

Answer:

Step-by-step explanation:

2.07 - 0.12 = 1.95

1.95 - 0.08 = 1.87

Juan finished at 1.87?

No.

It's easier to work in minutes and seconds.

2 minutes, 7 seconds = 1' 67"

1 minute 67 seconds minus 12 seconds = 1 minute 55 seconds

1' 55" - 8" = 1 minute 47 seconds

Please help! (I'll give brainliest to the first right answer.)

-BARSIC- [3]

Answer:

1. initial point is (2, 4)

reflected point is (-2, 4)

the coordinates are similar because they involve the same numbers, however, with the reflection across the Y axis, the X point became negative.

2. initial point is (2, 4)

reflected point is (2, -4)

again, same numbers but the X value becomes negative

Hope this helps!

A group of kids just finished trick-or-treating. The number of pieces of candy collected by each of the 5 kids

NemiM [27]

Answer:

$s = \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}$

$s =\sqrt{\frac{(31-35)^2 +(33-35)^2 +(36-35)^2 +(41-35)^2 +(34-35)^2}{5-1}} =3.808$

And the answer for this case would be :

$s= 3.81$ after round the value

Step-by-step explanation:

We have the following data set given:

31, 33, 36, 41, 34

If we want to find the standard deviation we need to find first the sample mean with this formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X = \frac{31+33+36+41+34}{5}= \frac{175}{5}= 35$

Now we can find the sampel deviation with this formula:

$s = \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}$

And replacing we got:

$s =\sqrt{\frac{(31-35)^2 +(33-35)^2 +(36-35)^2 +(41-35)^2 +(34-35)^2}{5-1}} =3.808$

And the answer for this case would be :

$s= 3.81$ after round the value
