During the first hour of operation the farm stand owner sold 15% of the apples he had. On the second hour he sold 20% of the rem
Gnesinka [82]

Answer:

22.95 kg

Step-by-step explanation:

Let's say the farm stand owner starts with x kg of apples.

During the first hour, he sells 15% of the apples:

0.15 x

This means he's left with 85% of the original apples.  During the second hour, he sells 20% of the remaining apples:

0.20 (0.85 x)

= 0.17 x

He's sold a total of 15% + 17% = 32% of the apples, so he's left with 68% of the apples.  Continuing the pattern, the apples sold during the third hour:

0.25 (0.68 x)

= 0.17 x

He's sold 49% of the apples and is left with 51%.  The apples sold during the fourth hour:

0.30 (0.51 x)

= 0.153 x

If 0.17 x = 25.5, then x = 150.  So the apples sold during the fourth hour is:

0.153 (150) = 22.95

How long will it take for an investment to triple, if interest is compounded continuously at 8%?
maw [93]

Answer:

<em>It will take 14 years before the investment triples</em>

Step-by-step explanation:

<u>Continuous Compounding</u>

Is the mathematical limit that compound interest can reach if it was calculated and reinvested into an account's balance over a theoretically infinite number of periods.

The formula for continuous compounding is derived from the formula for the future value of a compound interest investment:

FV = PV\cdot e^{i.t}

Where:

FV = Future value of the investment

PV = Present value of the investment

i     = Interest rate

t     = Time

It's required to find the time for an investment to triple, that is, FV = 3 PV, knowing the interest rate is i=8%=0.08.

Substituting the known values:

3PV = PV\cdot e^{i.t}

Dividing by PV:

3 = e^{i.t}

Taking logarithms:

\ln 3=i.t

Solving for t:

\displaystyle t=\frac{\ln 3}{i}

\displaystyle t=\frac{\ln 3}{0.08}

t = 13.7 years

Rounding up:

It will take 14 years before the investment triples

Neko [114]

Answer:

The correct answer is option (C)-0.245 = 2.160(0.205)

Step-by-step explanation:

Solution

Given that:

The slope = - 0.245

The size sample = n = 15

The standard error = 0.205

The confidence level = 95

The Significance level= α = (100- 95)% = 0.05

Now,

The freedom of degree = n-2 = 15 -2= 13

Thus,

the critical value = t* = 2.16

By applying Excel = [TINV (0.05, 13)]

The Margin of error is = t* (standard error)

=2.16 *0.205

= 0.4428
