The M&Ms milk chocolate color distribution is the following: 25% blue, 35% orange, 23% red, and 17% brown. In a bag, I found

164 blue M&Ms, 239 orange ones, 170 red ones and 136 brown ones. I am wondering whether my bag of M&Ms is representative of the manufacturer’s claim. Calculate the absolute value of the test statistic.

Answer:

1646.857

Step-by-step explanation:

The test statistic is obtained using the relation :

χ² = Σ (observed - Expected)² / expected

The observed values :

Blue = 164 ; Orange = 239 ; Red = 170 ; Brown = 136

Expected values:

Blue = 0.25 * 164 = 41 ;

Orange = 0.35 * 239 = 83.65

Red = 0.23 * 170 = 39.1

Brown = 0.17 * 136 = 23.12

Blue = (164-41)^2 / 41 = 369

Orange = (239 - 83.65)^2 / 83.65 = 288.507

Red = (170 - 39.1)^2 / 39.1 = 438.230

Brown = (136 - 23.12)^2 / 23.12 = 551.12

χ² = (369 + 288.507 + 438.230 + 551.12)

χ² = 1646.857

Solve the equation 5x + 7y = 35 for y.
erastovalidia [21]

Answer:

D. y = -5/7x + 5

Step-by-step explanation:

5x + 7y = 35

-5x          -5x

7y =  35 - 5x

/7      /7    /7

y = 35/7 - 5/7 x

y = 5 - 5/7x

Pie

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We need two points through which the line passes to find the slope:

(0, -4)\\(1,0)

We found the slope:

m = \frac {y2-y1} {x2-x1}\\m = \frac {0 - (- 4)} {1-0} = \frac {4} {1} = 4

So, the equation is of the form:

y = 4x + b

We substitute a point to find "b":

-4 = 4 (0) + b\\-4 = b

Finally, the equation is:

y = 4x-4
