Statistics is not an exact science, meaning that with any answer, there will be variance. This is because the sample size used to obtain values is always smaller than the population being studied.

<em><u>Explanation</u></em>:

A question with variability is a question that does NOT have one definitive answer. Instead, it has a range of different answers.

A statistical question is one that can be answered by collecting data. By nature, there will be variability in that data, because no two people will necessarily respond the same way.

An example of a statistical question would be asking a classroom of students how many hours they studied that week. After collecting the data, there will be multiple answers instead of just one.

harry invests £6000 in a savings account. the account pays 3.4% compound interest per year. work out the value of his investment
Nataly_w [17]

Invested amount (P0 = £6000.

Rate of interest (r) = 3.4% = 0.034.

We know compound interest formula

A = P(1+r)^t

We need work out the value of his investment per year.

So, we need to plug t=1 and plugging values of P and r in the formula above, we get

A = 6000(1+0.034)^1

A = 6000(1.034)

A = 6204.

<h3>Therefore, the value of his investment per year is £ 6204.</h3>

Now, we need to work out the value of his investment after 3 years.

So, we need to plug t=3.

A = 6000(1+0.034)^3

A = 6000(1.034)^3

1.034^3=1.105507304

A = 6000 × 1.105507304

A = 6633.04

<h3>Therefore, the value of his investment after 3 year is  £ 6633.04.</h3>

Lebron wants to put a fence around a community garden plot. The plot is a rectangular shape with a length twice as long as its w
tatyana61 [14]

Answer:

60 feet of fencing

Step-by-step explanation:

Let x feet be the width of the garden plot, then 2x feet is the length of  the garden plot.

The area of the garden plot is

A=x\cdot 2x\\ \\200=2x^2\\ \\100=x^2\\ \\x=10\ feet\\ \\2x=20\ feet

Find the perimeter of the rectangular garden plot:

P=x+2x+x+2x\\ \\=10+20+10+20\\ \\=60\ feet
