Answer:

A. linear

Step-by-step explanation:

A linear model is the best-fitting regression model for the data plot because for similar variations in x values, the variation in y values are also similar, that is, if you take points (x1, y1), (x2, y2) and (x3, y3) the y1 - y2 is similar to y2 - y3, when x2 - x1 is also similar to x3 - x2.

The graph shows the velocity f(t) of a runner during a certain time interval:

omeli [17]

Answer:

Option B

Step-by-step explanation:

(0,2)
(6,8)
(8,0)

Slope

m=8-2/6
m=6/6=1

And

m=0-8/8-6
m=-8/2
m=-4

These are acceleration

Y intercept is (0,2) as x coordinate is 0

This is initial velocity 2m/s

The runner stopped at 8s

Unproctored Placement ASThe quadrilaterals JKLM and PQRS are similar.Find the length x of PQ.JM=5, PS=4.5, JK=3.35K4.5PheHO1.8

Pachacha [2.7K]

Given that the quadrilaterals are similar, we know that:

$\frac{JM}{JK}=\frac{PS}{PQ}.$

Substituting the given values, we get:

$\frac{5}{4.5}=\frac{3}{x}.$

Solving the above equation for x, we get:

$\begin{gathered} 5x=3(4.5), \\ x=\frac{3(4.5)}{5}. \end{gathered}$

Simplifying the above result, we get:

$x=2.7$

<h2>Answer:</h2> $x=2.7$
