I don’t think so. It doesn’t fall directly into the 3 times table. I would say no.

No
Explain: The number 26 is 6 and 6 normally makes it a multiple. However, when you add the digits in 26 which is 2+6 that gives us 8 and 8 is not of the ending numbers. Therefore 26 is NOT a multiple of 3

B) 5,300

Step-by-step explanation:

Let x represents the pounds of food produced and y represents the profit in dollars,

Thus, the table that shows the given situation would be,

x    100          250       500         650         800

y   -11000     0          10300      11500      9075  

Since, the equation of a quadratic equation is,

y=A+Bx+Cx^2  

Where,

A=\overline{y}-B\overline{x}-C(\overline{x})^2

B=\frac{S_{xy} S_{x^2x^2}-S_{x^2y}S_{xx^2}}{S_{xx}.S_{x^2x^2}-(S_{xx^2})^2}

C=\frac{S_{x^2y}.S_{xx}-S_{xy}S_{xx^2}}{S_{xx}S_{x^2x^2}-(S_{xx})^2}

Also,

S_{xx}=\frac{\sum(x_i-\bar{x})^2}{n}

S{xy}=\frac{(x_i-\bar{x})(y_i-\bar{y})}{n}

S_{xx^2}=\frac{\sum(x_i-\bra{x})(x_i^2-\bar{x^2})}{n}

S_{x^2x^2}=\frac{\sum(x_i-\bar{x^2})^2}{n}

S_{x^2y}=\frac{\sum (x_i^2-\bar{x^2})(y_i-\bar{y})}{n}

By substituting the values,

We get,

A ≈ -20420.96

B ≈ 102.24

C ≈ -0.082

Hence, the quadratic equation that shows the given situation is,

y=-20420.96+102.24x-0.082x^2

For x = 350 pounds,

y=-20420.96+102.24(350)-0.082(350)^2

=5318.04

Which is nearby 5300,

Hence, option B is correct.
