What is the best estimate for the number of people in line at 7.A.M

Keith_Richards [23]

We have been given the equation

$y=-5.131x^2+31.821x-3.333$

It represents the number of people standing to catch a commuter train x hours after 5 A.M.

Now, in order to find the number of people in line at 7 a.m. , we need to substitute x= 2 in the above equation.

$y(2)=-5.131(2)^2+31.821(2x)-3.333\\y(2)= 39.785 \approx 40$

Therefore, the number of people in the line at 7 a.m. is 40

D id the correct option.

What are the solutions to the equation 3x2 + 15x = 18?

jok3333 [9.3K]

$3x {}^{2} + 15x = 18$

<h2>Divide the entire thing by 3</h2>

$x {}^{2} + 5x = 6$

$x {}^{2} + 5x - 6 = 0$

<h2>You can find the roots by using the quadratic formula or by using the form x²-Sx+P</h2>

$let \: \alpha \: and \: \beta \: be \: the \: roots$

<h2>Two numbers whose sum is -5 and product is -6</h2><h2>-6 and +1</h2>

<h2>Your answer is B</h2>

Answer:

(2, 12)

Step-by-step explanation:

Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".

The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"

If we assume that we have $3$ groups and on each group from $j=1,\dots,n_j$ we have $n_j$ individuals on each group we can define the following formulas of variation:
