State, Indiana

Income, Number of families

0, 1

5, 1

20, 3

25. 4

From the data, we have;

The total income for the families from Indiana = $2,260

The total income for the families from New Jersey = $2,565

The average income for the families from Indiana ≈ $64.57

The average income for the families from New Jersey ≈ $73.29

The median income for the families from Indiana = 0

The median income for the families from New Jersey = $55

The first quartile for the families from Indiana = $0

The first quartile for the families from New Jersey = $0

The third quartile for the families from Indiana = $85

The third quartile for the families from New Jersey = $120

Evaluate the geometric series

JulijaS [17]

Answer:

Option B is correct.

sum of given geometric series is, 255

Step-by-step explanation:

Evaluate the geometric series: $\sum_{i=1}^{8} 2^{i-1}$

we can write this as:

$1+2+4+.......+128$

Formula for the sum of the geometric series:

$S_n = \frac{a(r^n-1)}{r-1}$ for r > 1

where

a is the first term

n is the number of terms

r is the common ratio

In the given series:

common ratio (r) = 2>1, n = 8 and first term(a) = 1

Since,

$\frac{2}{1} = 2$

$\frac{4}{2} = 2$ and so on...

then substitute the given values in [1] we have;

$S_n = \frac{1((2)^8-1)}{2-1}$

$S_n = 256-1 = 255$

Therefore, the sum of given geometric series is, 255

HELP ME PLEASE !!!!!!!!!

Kay [80]

Answer: 33 333,33 per month or 400 000 per year

Step-by-step explanation:

You need 48 000 + 0.035X = 62 000

So ( 62 000 - 48 000 ) / 0.035 = X

Then you can divide X per 12 (months in a year)

And you have your answer per month .

So 33 333,33 total sale per month to have at least as high as the average pay

JulijaS [17]

Answer: The area of the circular wooden table = 50.24 ft²

Step-by-step explanation:

Given: The radius of the circular table = 4 feet

We know that area of a circle is given by :-

$\text{Area}=\pi r^2$

Therefore, the area of circular wooden table is given by :-

$\text{Area}=3.14(4)^2\\\Rightarrow\ 3.14\times16\\\Rightarrow\text{Area=}50.24\ ft^2$

The area of the circular wooden table = 50.24 ft²
