After 12 years I shall be three times as old as I was 34years ago. Determine my present age

Answers

Answer 1

Answer:

the 34 yrs Is wrong it will be 4yrs only.

Step-by-step explanation:

Let my present age=x years

After 12 years my age=x+12 years

4 years ago my age =x−4 years

According to the question,

x+12=3(x−4)

⇒x+12=3x−12

⇒3x−x=12+12

⇒2x=24

or x= 24/2 =12 years.

∴ my present age is 12 years.

hope this helps you.

Answer 2
Let the present age of let’s say todd be X

Todd’s age (x+12) will be 3 times as old as he was 4 years ago [3(x-4)]

i.e



x+12=3(x-4)
x+12=3x-12

2x=24
X=12.
Hence Todd’s present age is 12.

27. Representative Sample? You want to determine the average number of classes skipped by
first-year students at a small college during a particular semester. State whether each of the
following samples is likely to be representative and explain why or why not.
Sample 1: 100 first-year students who belong to a sorority or fraternity
Sample 2: 100 first-year students who play a varsity sport
Sample 3: The first 100 first-year students whom you meet at the student union
Sample 4: 100 first-year students taking honors humanities,, courses

Answers

A sample is said to be representative if the selection made form have population is free of bias. Evaluating the selection criteria listed above :

Sample 1 will not likely be representative as students who do not belong to either a sorority or fraternity are automatically exempted from the selection.

Sample 2 will not likely be representative because not all students play a varsity sport, hence students who do not play a varsity sport won't have a chance of being selected.

Sample 3 is a convenience sampling technique, they often exhibit sampling bias hence, sample 3 is not representative of the population.

Sample 4 will not likely be representative as students taking other courses aside humanities have no chance of being selected.

Therefore, all the sampling methods are not representative of the population of first year student.

round 0.25 to the nearest hundredth ​

Answers

Answer:

0.25

Step-by-step explanation:

there is no hundredth in 0.25

Rounding 0.25 to the nearest hundredth gives us 0.26.

We must look at the digit in the thousandth place, which is the following decimal place after the hundredth place, in order to round 0.25 to the closest hundredth.

We round up the digit in the hundredth place by adding 1 since the digit in the thousandth place is 5, which is equal to or larger than 5.

Thus, 0.26 is obtained by rounding 0.25 to the next tenth.

0.25 (initial number) worked

(Number in the thousandth place) (Number in the hundredth position)

We round up the digit in the hundredth place since the digit in the thousandth place is 5, which is 5.

Hence rounding to the nearest hundredth, 0.25 equals 0.26.

Answers

Answer: ite will be 3 bc i done that all ready

Step-by-step explanation:

The number of individuals that work for the company is 272 workers.

Given,

The Parker company employs 68 part-time workers.

This represents 4% of the total workforce.

We need to find out how many individuals work for the company.

What is percentage?

Percentage is a fraction or a ratio in which the value of whole is always 100.

Find the total workforce.

Total workforce = 100%

We have,

4% = 68 workers

Multiply 25 on both sides.

25 x 4% = 4 x 68 workers

100% = 272 workers.

This means the number of individuals that work for the company is 272 workers.

Thus the number of individuals that work for the company is 272 workers.
