A teacher wants to choose a student at random. The teacher decides to choose the first person to walk through the classroom door at the start of the lesson.
a. Explain why this is not a good method.
b. Suggest a better method.

Answers

Answer 1
A. The method is not a good method because the student that walks through the door first is probably the student who always walks through the door first. This makes the choosing not random and makes it a biased choice.

B. The teacher should pulls sticks with the students names on it, or use a random name generator.
Answer 2

Answer:

It is not a good method because the first person to walk through the door should be rewarded for being on time and it is pretty much  that the first person to walk in is always the first to walk in  

They should have a  volunteer and make them do it step by step for other kids to see or if someone is late  make them do it

Sweety’s mother is 12 years more than twice Sweety’s age. After 8 years, she will be 20 years less than three times Sweety’s age. Find Sweety’s age and Sweety’s mother’s age?
*******x******
please show work if can

Answers

Answer: 44

Step-by-step explanation:

Let your age be x.

Then your mother's age will be 2x + 12.

After 8 years,

Your age will be x + 8.

Your mother's age will be 3(x + 8) - 20 = 3x + 24 - 20 = 3x + 4.

This is equal to 2x + 12 + 8 = 2x + 20

2x + 20 = 3x + 4

3x - 2x = 20 - 4

= x = 16

I think it will be 16

1/3x+5=23 is equation to represent the dogs’ weights and weight of Luisa' dog is 54 pounds.

What is Equation?

Two or more expressions with an Equal sign is called as Equation

Let f represent the weight of Luisa’s dog.

Fabiola’s dog is 5 pounds heavier than one-third of the weight of Luisa’s dog.

Luisa' dog weight: x pounds

One-third of the weight of Luisa’s dog: 1/3x pounds

5 pounds heavier than one-third of the weight of Luisa’s dog : 1/3x+5

Fabiola's dos weight: 1/3x+5pounds that is 23 pounds.

1/3x+5=23

Subtract 5 from both sides

x/3=18

x=54 pounds

Hence, 1/3x+5=23 is equation to represent the dogs’ weights and weight of Luisa' dog is 54 pounds.

Answer:

The total least sale amount is $5,000,000

Step-by-step explanation:

Given as :

The base salary amount of Carmen = $125,000

The commission percentage on total sale = 4%

The performance bonus amount = $25,000

The total compensation amount last year = $350,000

Let The total sale amount = $x

According to question

Total compensation amount last year = base salary amount + percentage on total sale + performance bonus amount

I.e  $350,000 =  $125,000 + 4% of x + $25,000

Or, $350,000 =  $150,000 + 4% of x

Or, 4% of x =  $350,000 - $150,000

Or, 4% of x =  $200,000

Or,  × x =  $200,000

Or, x =

∴   x = $5,000,000

So, The total sale amount = x = $5,000,000

Hence, The total least sale amount is $5,000,000  Answer

Step-by-step explanation:

The answer is 5,000,000

"You figure you can ride Ghost Wind, then get on. Just bring him back to the stable when you're finished so I can rub him down." I dismounted, leaving the stallion with Mitchell, and headed toward the barn. Now, I truly expected that Mitchell would come after me with Ghost Wind. After all, despite my invitation, I knew Mitchell couldn't ride Ghost Wind. As far as I knew, Mitchell had never ridden more than a mule and had no idea how to ride a thoroughbred tornado like Ghost Wind. But instead of Mitchell following me, the next thing I knew, I heard a triumphant cry, turned, and saw Mitchell atop the stallion dashing across the meadow. For a moment all I could do was stand and stare. But then, as the stallion bucked, left the meadow, and headed for the woods, I suddenly found my legs and my voice, and I began running and screaming after Mitchell and the stallion.
