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

A new car depreciates as soon as you drive it out of the parking lot. A certain car depreciates to half its original value in 4
Alexandra [31]

Answer:

Original price of car = $20,000

Step-by-step explanation:

Let the original price of the car be 'x' dollars.

Given:

Here, the depreciation of the car is occuring exponentially as the value depreciates to half in every four years.

Worth of car after 8 years = $5000

Value after depreciation in 4 years = Half of original value = \frac{x}{2}

So, value of car after depreciation in another 4 years = Half of the value after 4 years = \frac{1}{2}(\frac{x}{2})=\frac{x}{4}

Therefore, final depreciated value after 8 years is \frac{x}{4}.

But, as per question, final depreciated value is $5000. Thus,

\frac{x}{4}=5000\\x=5000\times 4\\x=20000

Therefore, the original price of the car was $20,000.

Emily baked 3 batches of sugar cookies each. She ate 2 of the cookies and gave 10 of them to her neighbor. In return, her neighb
Vikentia [17]

Answer:

The answer is 198.

Step-by-step explanation:

First you need to know how much is a batch of cookies which is 60. Since she made 3 batches that means you will need to multiply 3 by 60, which will give you 180 cookies. Next you will need to add 2 to 10 because thats how much were took. That equals 12. Subtract 12 from 180 and that will give you 168. Last but not least you will need to add 30 because that is half the batch of cookies her neighbor gave to her. So 168 plus 30 equals 198.
