Find the values of the 30th and 90th percentiles of the data. Please show your work.

MaRussiya [10]

Answer:

30th percentile:109

90th percentile: 188

Step-by-step explanation:

The given data set is:

129, 113, 200, 100, 105, 132, 100, 176, 146, 152

We arrange the data set in ascending order to obtain;

Array= $100,100,105,113,129,132,146,176,200$

The 30th percentile is located at

$(\frac{30}{100}\times 10 )}$ -th position, where n=10 is the number of items in the data set

This implies that the 30th percentile is at the 3rd position.

Since 3 is an integer, the 30th percentile is the average of the 3rd and 4th occurrence in the array;

This implies that the 30th percentile = $\frac{105+113}{2}=\frac{218}{2}=109$

The 90th percentile is located at

$(\frac{90}{100}\times 10 )}$ -th position, where n=10 is the number of items in the data set

This implies that the 90th percentile is at the 9th position.

Since 9 is an integer, the 90th percentile is the average of the 9th and 10th occurrence in the array;

This implies that the 90th percentile = $\frac{176+200}{2}=\frac{376}{2}=188$

rick deposited $6200 in a savings account with simple interest. three years later, the account held $7130 what was the interest

Law Incorporation [45]

1) Gathering the data

P=$6200

F=7310

t= 3 yrs

2) Since it is a simple interest, it is a linear application. So we can find it using this formula:

E) Natasha's parents want to support Natasha by saving $5000 for her college. They searched up for some investment options and c

Bas_tet [7]

Answer:

Amount she would have in 2 years at a simple interest of is

$5000 + ($5000 x 0.048 x 2) = $5480

Amount she would have in 2 years at a 4.1 % / year compounded semi- annually is :

$5000 x ( 1 +0.041/2)^4 = $5422.78

the first option yields a higher value in two years when compared with the second option. Thus, the first option is the best one to choose

Step-by-step explanation:

Future value with simple interest = principal + interest

Interest = principal x interest rate x time

0.048 x 5000 x 2 = 480

future value = $480 + 5000 = $5480

The formula for calculating future value with compounding:

FV = P (1 + r)^nm

FV = Future value

P = Present value

R = interest rate

m = number of compounding

N = number of years

5000 x ( 1 + 0.041 / 2)^(2 x 2) = $5422.78

Consider the formula P = \dfrac{ H\cdot d}{m}P=

Lilit [14]

Answer:

The productivity is measured in cubic meters per kilogram.

Step-by-step explanation:

For the formula for the productivity $P$ of the camel

$P = \dfrac{ H\cdot d}{m}$

where $H$ is the area of the hump and is measured in square meters, $d$ is the distance the camel can travel (measure in meters), and $m$ is the mass of the camel (measured in kilograms $kg$ ).

Then, the productivity of the camel is measure in

$P=\dfrac{meters^2\:*meters}{kilograms}$

$P=\dfrac{m^3}{kg}$

cubic meters per kilogram.
