Answer:

Area = 100m²

Step-by-step explanation:

Given :

Height of triangle = 10 m

Length of base = 2 * height = 2 * 10 = 20 m

Area of right angle triangle :

1/2 * base * height

Area = 1/2 * 20 * 10

Area = 0.5 * 10 * 20

Area = 100m²

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

Answer:

2500 pence (C = 2500)

Step-by-step explanation:

C = 10t + 20m

From the given information, t is the number of texts so essentially you will plug in the number of texts provided (150) in the place of the variable t.

C = 10(150) + 20m

Apply the same thing to minutes, plug in the number of minutes (50) in the place of the variable m.

C = 10(150) + 20(50)

Now multiply the substitutes with the co-efficient.

C = 1500 + 1000 (10*150=1500 & 20*50=1000)

Add the addends

C = 2500
