the one on the top is a parrallelogram, the one on the bottom is a trapezoid
9000 equals to 900 tens. ( 1. 9×10=90,
2. 90×10=900,
3. 900×10=9,000. )
<span>The infinite series whose terms are the natural numbers 1 + 2 + 3 + 4 + â‹Ż is a divergent series. The nth partial sum of the series is the triangular number
{\displaystyle \sum _{k=1}^{n}k={\frac {n(n+1)}{2}},} \sum_{k=1}^n k = \frac{n(n+1)}{2},
which increases without bound as n goes to infinity. Because the sequence of partial sums fails to converge to a finite limit, the series does not have a sum.
Although the series seems at first sight not to have any meaningful value at all, it can be manipulated to yield a number of mathematically interesting</span>
Answer:
The new pyramid has a volume that is 8 times the volume of the original pyramid
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z ----> the scale factor
V_1 -----> volume of the original pyramid
V_2 -----> volume of the new pyramid
In this problem we have that each of the dimensions of the original pyramid are doubled
so
so
substitute
therefore
The volume of the new pyramid is 8 times the volume of the original pyramid
The answer is Demographic data
The researcher includes the following material in a research report: The seven males varied in age from 32 to 45 (M = 38), had a high school education (two had high school diplomas, one had an associate degree, three had an undergraduate degree, and one had a master's degree), and had yearly incomes ranging from $20,000 to $100,000 (M = $52,000). Demographic data refers to information on the characteristics of the individuals being investigated.
What is Demographic data?
- Demographic analysis is the examination of a population's characteristics such as age, ethnicity, and gender.
- Demographic data is a statistical representation of socioeconomic information such as employment, education, income, marriage rates, birth and death rates, and so on.
- Age, race, ethnicity, gender, marital status, income, education, and occupation are some examples of demographic information. With survey questions, you may quickly and efficiently collect this sort of information.
