Answer:

Step-by-step explanation:

set 30

1) 90-52 = x

38 = x

2) 90 -15-25=x

50 = x

set 31

1) t = 3m

m = independent

t = dependent

m t

$\left[\begin{array}{ccc}1 & 3\\2 & 6\\3 & 9\\4&12\\5&15\\6&18\end{array}\right]$

m = 25d

d = independent

m = dependent

m d

$\left[\begin{array}{ccc}1&25\\2&50\\3&75\\4&100\\5&125\\6&150\\7&175\end{array}\right]$

Which of the following functions best fits the data shown in the scatterplot below? y=100x+2y is equal to 100 x plus 2 y=20x2+10

KengaRu [80]

The equation of the scatter plot is (a) y = 100x + 2

<h3>How to determine the equation of the scatterplot?</h3>

The line of best fit of the scatter plot passes through the points

(x,y) = (0,2) and (1,102)

Start by calculating the slope using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

So, we have:

$m = \frac{102 - 2}{1 - 0}$

m = 100

The equation is then calculated as:

y = m(x - x1) + y1

This gives

y = 100(x -0) + 2

Evaluate

y = 100x + 2

Hence, the equation of the scatter plot is (a) y = 100x + 2
