The amount of carbon-14 present in a paint after t years is given by y equals y Subscript o Baseline e Superscript negative 0.0

Anni [7]

Answer:

16,383.33 years ( approx )

Step-by-step explanation:

Given equation that shows the amount of carbon-14 after t years,

$y = y_0 e^{-0.00012t}$

Where,

$y_0$ = initial amount,

∵ 14% of $y_0$ = $\frac{14}{100}y_0$ = $\frac{7}{50}y_0$

$\frac{7}{50}y_0= y_0 e^{-0.00012t}$

$\frac{7}{50}=e^{-0.00012t}$

Taking ln both sides,

$\ln(\frac{7}{50})=-0.00012t$

$-1.966=-0.00012t$

$\implies t =\frac{-1.966}{-0.00012}=16383.33$

Hence, the painting would be 16383.33 years old ( approx )

A couple deposits $23,000 earning 3% annual intrest for 30 years. calculthe future value of the investment of the intrest is com

Hoochie [10]

A = 23,000(1 + .03/365)^365(30)
A = 23,000(1.000082192)^10950
The answer is $56,569 or $56,568.92

Hope this helps :)

What is quartile 1 (Q1)quartile 3 (Q3) and the IQR? Answer all three parts . 13, 23, 24, 25, 26, 26, 37, 47, 47, 48, 50

Fittoniya [83]

Answer:

Quartile 1 (Q1) = 24

Quartile 2 (Q2) = 47

IQR = 23

Step-by-step explanation:

Given:

The set of data are:

13, 23, 24, 25, 26, 26, 37, 47, 47, 48, 50

The data are in increasing order. The number terms are, $n = 11$ .

Therefore, the middle term = $\frac{n+1}{2}=\frac{11+1}{2}=6^{th}\ term$

So, the median = 26

Now, the median divides the set of data into two parts. The median of first part is the quartile 1 and the median of second part is quartile 2.

So, the first part has the following terms:

13, 23, 24, 25, 26

Here also, $n=5$ . So, the third term is the median.

∴ Q1 = 24

The second part has the following terms:

37, 47, 47, 48, 50

Here also, $n=5$ . So, the third term is the median.

∴ Q2 = 47.

Now, IQR = Q2 - Q1 = 47 - 24 = 23.
