Based on the scatterplot, which equation BEST represents the relationship between velocity and time?

lutik1710 [3]

The line of best-fit that represents the relationship between velocity and time is:

v = 2.19t + 6.7.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (t,v) are given as follows:

(0, 6.1), (2.1, 12.2), (5.3, 17.4), (8.2, 26.4), (10, 28.1), (12.1, 32.8).

Hence, inserting these points into a calculator, the equation is given by:

v = 2.19t + 6.7.

Andre says that 5 3/4 + 2 1/4 = 7 1/2 because 7 4/8 = 7 1/2. Identify his mistake. Draw a picture to prove that he is wrong.

MA_775_DIABLO [31]

Answer:

Step-by-step explanation:

The given expression is

$5\frac{3}{4}+2\frac{1}{4} =7\frac{4}{8}=7\frac{1}{2}$

We will rewrite the expression

$\frac{23}{4}+\frac{9}{4} =\frac{60}{8}=7\frac{1}{2}$

When we add the fraction

$\frac{23+9}{4}$ = $\frac{32}{4}$ = 8

While Andre says the answer is $7\frac{1}{2}$

because Andre added the denominator where he has to make a common denominator that should be 4 instead of 8.

Andre made mistake in this step
