Answer: Frequencies .

Step-by-step explanation:

In statistics theory the chi-square test statistic is calculated by considering each cell and the expected frequency is subtracted from the observed frequency after that the difference is squared, and the total is divided by the expected frequency.

a medication prescription states 1/4 tablet twice a day per 20kg the peson weight is 211 pounds. how many tablets should be take
Black_prince [1.1K]
<h2>Hello!</h2>

The answer is: 1.187 tablets each time (twice a day)

<h2>Why?</h2>

From the statement we know that 0.25 tablet (1/4) should be taken twice a day per 20 kg, it makes 0.5 table a day, per 20 kg.

First, we need to convert the given weight unit (pounds) to kg:

1 Pound=0.45Kg

So,

211Pounds*\frac{0.45Kg}{1Pound}= 94.95Kg=95Kg

A weight of 95 Kg, means 4.75 times more than the given information of 0.5 table a day, per 20 Kg

\frac{95Kg}{20Kg}=4.75

Then,

4.75*(0.5)=2.375

So,

For a weight of 95 Kg,  2.375  tablets should be taken a day, or 1.187  tablets each time.

Have a nice day!

Please help me find the length width and area
Lisa [10]
I would say that the length would be 2 inches, the width to be 6 feet and the area to be 144. I would say this because in order to find the area, you would need to convert 6 feet into inches. There are 12 inches in a foot. So it would be 72 inches. In order to find area you multiply the length by the width. So it would be 72 time 2, this is equal to 144. Hope this helps :)

3. Write a pair of linear equations which has the unique solution x= 1 , y= -1.
noname [10]

Step-by-step explanation:

The equations with solution x = 1 and y = (-1) will intersect each other at (1,-1) .

<u>Equation</u><u> </u><u>1</u><u> </u><u>:</u><u>-</u>

  • Say slope is 1 .

→ y - (-1) = 1 ( x -1)

→ y +1 = x -1

→ x - y -2 = 0

<u>Equation</u><u> </u><u>2</u><u> </u><u>:</u>

  • Slope = -1

→ y - (-1) = -1( x -1)

→ y +1 = -x +1

→ x + y = 0
