The sum of the series b 2 b 4 b 6 b 8 b {10} is [tex]$\dfrac{180}{3}$[/tex] since it is a geometric series with a common ratio of [tex]$\dfrac{7}{4}$[/tex].

Since the given series [tex]$b 1 b 2 b 3 \cdots b {10}$[/tex] has a sum of 180, it can be deduced that the series is a geometric series with a common ratio of[tex]$\dfrac{7}{4}$[/tex]. This means that the ratio of any two consecutive terms in the series is a constant, [tex]$\dfrac{7}{4}$[/tex]. Therefore, the sum of the series b 2 b 4 b 6 b 8 b {10} can be calculated as follows:

[tex]$S = b2 + b4 + b6 + b8 + b_{10}$[/tex]

[tex]$= b2\left(\dfrac{7}{4}\right)^0 + b2\left(\dfrac{7}{4}\right)^2 + b2\left(\dfrac{7}{4}\right)^4 + b2\left(\dfrac{7}{4}\right)^6 + b2\left(\dfrac{7}{4}\right)^8$[/tex]

[tex]$= b2 \left[1 + \left(\dfrac{7}{4}\right)^2 + \left(\dfrac{7}{4}\right)^4 + \left(\dfrac{7}{4}\right)^6 + \left(\dfrac{7}{4}\right)^8\right]$[/tex]

[tex]$= b2 \left[\dfrac{1-\left(\dfrac{7}{4}\right)^{10}}{1-\left(\dfrac{7}{4}\right)^2}\right]$[/tex]

[tex]$= b2 \left[\dfrac{1-\left(\dfrac{7}{4}\right)^{10}}{\dfrac{3}{4}}\right]$[/tex]

[tex]$= \dfrac{4b2}{3} \left[1-\left(\dfrac{7}{4}\right)^{10}\right]$[/tex]

Since the sum of the series[tex]$b 1 b 2 b 3 \cdots b {10}$[/tex] is 180, we can substitute $b2$ with [tex]$\dfrac{180}{3}$[/tex]nd calculate the sum of the series $b 2 b 4 b 6 b 8 b {10}$:

[tex]$S = \dfrac{4\left(\dfrac{180}{3}\right)}{3} \left[1-\left(\dfrac{7}{4}\right)^{10}\right]$[/tex]

[tex]$= \dfrac{180}{3} \left[1-\left(\dfrac{7}{4}\right)^{10}\right]$[/tex]

Therefore, the sum of the series [tex]$b 2 b 4 b 6 b 8 b {10}$ is $\dfrac{180}{3}$[/tex].

Plug this into a calculator and it will give you 6.70820....
Rounding to the nearest tenth will give you, about 6.7.

The length of the hypotenuse of a right triangle can be calculated using the Pythagorean theorem: c^2 = a^2 + b^2.

Given that a = 3 meters and b = 6 meters, we can substitute those values into the equation:

c^2 = 3^2 + 6^2

c^2 = 9 + 36

c^2 = 45

c = sqrt(45)

c = 6.7 meters

Rounding to the nearest tenth, c = 6.7 meters becomes c = 6.7 meters.

Answer: Let's call the number of pages printed "x". After printing x pages, the total cost for the Hewlett-Packard printer will be:

$200 + $0.03 * x

And the total cost for the Brother printer will be:

$240 + $0.01 * x

We want to find the number of pages "x" such that the cost of the two printers is the same, i.e., when:

$200 + $0.03 * x = $240 + $0.01 * x

We can isolate x by subtracting $240 from both sides and subtracting $0.01 * x from both sides:

$200 - $240 + $0.03 * x - $0.01 * x = 0

$-40 + $0.02 * x = 0

$0.02 * x = 40

x = 2000

So, the number of pages that need to be printed for the cost of the two printers to be the same is 2000 pages.

At 0.05 alpha level, your claim is not significant.

In null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct.

Given is that a friend read online that 37% or less Americans have a gun in their household. I claim that the percent of Americans that have a gun in their household is actually greater than 37%. To test this claim, I survey 200 random Americans and find that 86 of them have a gun in their household. The alpha level is at .05.

We can write -

P{E} % = 86/200 x 100

P{E} % = 86/2

P{E} % = 43%

For b to be  in the plane spanned by a1 and a2, h= -17 .

What is plane?

In two dimensions, a plane can continue on forever. The lack of breadth. A plane is an example of coordinate geometry. A point's location in a plane is determined by its coordinates.

A plane is a two-dimensional, flat surface that never ends in mathematics. A plane is a two-dimensional equivalent of a three-dimensional equivalent that contains three spatial dimensions, a line, and a point. Planes can resemble subspaces in some higher-dimensional situations, as if the room's walls had been substantially stretched. These walls have their own existence, exactly as in the context of Euclidean geometry.

A flat surface in three dimensions can be represented using the plane equation. There are several approaches for determining the equation for a given function.. The equation for the plane can be expressed in either cartesian form or vector form.

Hence, the general form of the equation is A(x−x1)+B(y−y1)+C(z−z1)=0

Now,

y is a linear combination of a1 and a2 if it is in the plane, For the plane spanned by a1 and a2,

y = a a1 + b a2, a and b are constants here

[4,1,h] = a[1,4,-2] + b[-2,-3,7]

[4,1,h] = [a - 2b,4a -3b,-2a+ 7b] Vectors are equal if their components are equal by the rules of vector addition and multiplication.

4 = a - 2b

1 = 4a - 3b

h = -2a + 7b

solve for a and b from the two equations for h:

a = -2

b = -3

h = -17

We see that -2[1,4,-2] - 3[-2,-3,7] = [4,1,-17].

Hence,

             For b to be  in the plane spanned by a1 and a2, h= -17 .

Using the law of Sine, the value of y becomes 1.6 units.

Correct option: B

Rule of Sines The sine law, sine formula, sine rule, or law of sines is an equation in trigonometry that connects the lengths of any triangle's sides to the sines of its angles. The ratio of a triangle's sides and angles may be calculated using the sine rule.

The formula: a/sinA = b/sinB = c/sinC

It may be used to describe the sine rule. Here, the triangle's angles are A, B, and C, while its sides' lengths are denoted by the letters a, b, and c.

The sine rule:

a/Sin A = b/Sin B = c / Sin C = 2R

Computation of Current assets and Current Liabilities

Current Ratio  (CR) = Current Assets (CA)/ Current Liabilities (CL)  = 2.5

So, CA= 2.5 CL

Current Assets (C.A) - Current Liabilities (C.L) now equals Rs. 60000 as working capital.

Therefore, CA - CL = 60000 0

     2.5 CL-CL = 600000

     1.5 CL = 600000

        CL = 600000/1.5

     C.L = Rs.40000 0

C.A. now equals 2.5 x 400000, or Rs. 1000,000.

Computation of stock

Liquid ratio   = Liquid  assets/Current  liabilities

Or, 1.5 = (Current Assets - Stock )/400000

Or, 1.5  = (10,00, 000 - Stock)/4,00,000

1.5 *400000 = 1000000-Stock

600000 = 1000000- Stock

Therefore, stock = 100000-600000 = 400000

Computation of Proprietary fund; Fixed assets; Capital and Sundry payables (creditors)

Proprietors Fund divided by Permanent Assets equals Proprietors Fund.

Permanent assets therefore equal 0.75 proprietary fund, and

Net working capital  =  0.25 Proprietary fund

Therefore Proprietary fund = 600000/0.25

Proprietary fund = 24,00,0000 and  Fixed assets = 0.75 proprietary fund

= 0.75 of  24,00,000

Therefore, Fixed Assets = 18,00,000

Equity Capital = Proprietary fund - Reserves & Surplus

Therefore, Equity Capital = 2400000-400000

Equity Capital = 20,00,000

Variable payables (creditors) = (Current liabilities - Bank overdraft)

= (400000 - 100000) = 300000

Sundry payables = 300000

Net Current Assets =  (Current Assets - Stock) = 1000000-400000 = 600000

Step 2: (d-3)(d^2+d-2) = d^3+d^2-2d-3d^2-3d+6 = d^3-2d^2-5d+6

Answer: The product of the binomials (d-1)(d+2)(d+3) is [tex]d^3 + 4d^2 +d - 6[/tex].

Step-by-step explanation:

When multiplying the binomials, you can break it down and multiply two expressions first then multiply that last expression:

(d−1)(d+2)(d+3)

first: (d−1)(d+2)

when multiplying expressions you can multiply using the 'box method' where you would draw a box and put each part of the expression on the top and the left side of the box, multiplying each on into the box and adding like terms.

You can also multiply it by first taking the expression, (d−1)(d+2) and multiplying the variable 'd' to the (d + 2) and then multiplying the '-1' to the (d+2) and then adding like terms:

(d−1)(d+2)

[tex]d^{2} + 2d - d - 2[/tex]

'd' is the only like term in this expression so lets add 2d and -d together

[tex]d^{2} + d - 2[/tex]

finally, we need to multiply the (d + 3) to expression, [tex]d^{2} + d - 2[/tex]

We will treat this multiplying process the same as before.

[tex](d + 3)(d^{2} + d - 2)[/tex]

[tex]d^3 + d^2 -2d + 3d^2 + 3d - 6[/tex]

now lets add like terms

[tex]d^3 + 4d^2 +d - 6[/tex]

So the product of the binomials (d-1)(d+2)(d+3) is [tex]d^3 + 4d^2 +d - 6[/tex].
