Answer:

If we solve for k we can do this:




So then we have at last 75% of the data withitn two deviations from the mean so the limits are:


Step-by-step explanation:
We don't know the distribution for the scores. But we know the following properties:

For this case we can use the Chebysev theorem who states that "At least
of the values lies between
and
"
And we need the boundaries on which we expect at least 75% of the scores. If we use the Chebysev rule we have this:

If we solve for k we can do this:




So then we have at last 75% of the data withitn two deviations from the mean so the limits are:


Answer:
She will pay $7,500 interest over the 5 years
She will have to pay back $17,500 in total
Step-by-step explanation:
Let us revise the rule of the simple interest
<em>I</em> = <em>Prt</em> and <em>A</em> = <em>P</em>(1 +<em> rt</em>)
, where:
- A = Total Accrued Amount (principal + interest)
- r = Rate of Interest per year in decimal
- t = Time Period involved in months or years
∵ Leah borrows £10,000 over 5 years at a simple interest rate of 15%.
∴ P = 10,000
∴ t = 5
∴ r = 15% =
= 0.15
→ Substitute them in the first rule to find the interest
∵ I = 10,000(0.15)(5)
∴ I = 7,500
∴ She will pay $7,500 interest over the 5 years
→ Let us find A
∵ A = 10,000(1 + 0.15×5)
∴ A = 17,500
∴ She will have to pay back $17,500 in total
