A county manager used a representative sample of two populations in the county to determine the number of pounds of trash thrown

away per person per week. The results are shown in the dot plots below. Sample 1: A dot plot titled Sample 1. A number line going from 0.5 to 2.5 in increments of 0.5 is labeled Pounds of Trash. There is 1 dot above 0.5, 3 above 1, 4 above 1.5, 2 above 2, and 2 above 2.5. Sample 2: A dot plot titled Sample 2. A number line going from 0.5 to 2.5 in increments of 0.5 is labeled Pounds of Trash. There are 2 dots above 0.5, 3 above 1, 4 above 1.5, 2 above 2, and 1 above 2.5. The town manager uses the median to show that the average amount of trash thrown away per person per week in each sample is the same. What is the town manager’s error? The medians of the data sets are not the same. He should have used the mean to determine the average because the data sets are approximately symmetric. He should have used the IQR of the data sets to determine the average because the first data set has more large numbers than the second data set. He should have used the MAD to determine the average because the data sets do not contain outliers.

Suppose the man in the St. Ives poem has x wives, each wife has x sacks, each sack has x cats, and each cat has x kits. Write an
marishachu [46]

Answer: x+x^2+x^3+x^4

Step-by-step explanation:

As per given,

Number of wives = x

Number of sacks = x (\text{Number of wives} )= x\times x = x^2

Number of cats = x(\text{Number of sack})= x \times x^2=x^3

Number of kits = x(\text{Number of cats} )=x\times x^3=x^4

Now , the total number of kits, cats, sacks, and wives going to St. Ives = x+x^2+x^3+x^4

Hence, the required ex[pression:  x+x^2+x^3+x^4

The common ratio of a geometric series is 3 and the sum of the first 8 terms is 3280.
Pavlova-9 [17]

Answer:

The first term of the geometric series is 1

Step-by-step explanation:

In this question, we are tasked with calculating the first term of a geometric series, given the common ratio, and the sum of the first 8 terms.

Mathematically, the sum of terms in a geometric series can be calculated as;

S = a(r^n-1)/( r-1)

where a is the first term that we are looking for

r is the common ratio which is 3 according to the question

n is the number of terms which is 8

S is the sum of the number of terms which is 3280 according to the question

Plugging these values, we have

3280 = a(3^8 -1)/(3-1)

3280 = a( 6561-1)/2

3280 = a(6560)/2

3280 = 3280a

a = 3280/3280

a = 1
