There is no association between the chicken preferences and rice preferences. Option C

<h3>What is association?</h3>

There is an association between two variables when they both decrease or increase simultaneously. In many cases, the association between the variables can be shown using the correlation coefficient when the relationship is plotted on Cartesian coordinates.

If we look at the table, we can see that there is no association between the chicken preferences and rice preferences because because the proportion of chicken and rice eaters to all chicken eaters is lower than all rice eaters to all eaters; and because the proportion of chicken and rice eaters to all rice eaters is lower than all chicken eaters to all eaters.

(¬‿¬) Find the number of real number solutions for the equation. x^2+9x+20=0
mart [117]

To find the nature of solutions of a quadratic equation we can find the discriminant.

The standard form of a quadratic equation is ax² + bx + c = 0.

Formula to find the discriminant = b² - 4ac.

So, first step is to compare the given equation with the above equation to get the value of a, b, and c.

After comparing the two equations we will get a =1, b = 9 and c = 20.

Next step is to plug in these value in the formula of discriminant. So,

Discriminant = 9² - 4(1)(20)

= 81 - 80

= 1

Since 1 is a positive perfect square number.

So, we will get two real solutions for this equation.

Hence, the correct choice is C.

Hope this helps you.

You can stuff envelopes twice as fast as your friend. Together, you can stuff 6750 envelopes in 4.5 hours. How long would it tak
Lynna [10]
If you're twice a fast then... we'll divide 6750 by 3, that equals 2250. 
<span>Equation.. y=your friend and you would be 2y cuz you're twice as fast.
</span>y+2y=6750, 
3y=6750
y=2250

Your friend stuffed 2250 in 4.5 hrs.
You (twice as fast) stuffed 4500 in 4.5 hrs.


Working alone, your friend can stuff 2250 in 4.5hrs so it would take 13.5hrs to stuff 6750. 
Equation.. (6750/2250) x 4.5hrs = 13.5hrs

You can 4500 in 4.5hrs so it would take you 6.75 hrs to stuff 6750.
Equation.. (6750/4500) x 4.5hrs = 6.75 hrs.

What is the slope of the line whose equation is 12 equals 4x - 3 y?
lisov135 [29]
12=4x-3y Begin by moving the 4x away from the y. -3y=-4x+12. To get y by itself, divide both sides by -3. y= 4/3x -4. Therefore the slope is 4/3.
