Answer:

the magnitude of the error is 2.9959 × 10⁻⁹

Step-by-step explanation:

By Alternating series estimation theorem

[tex]\sum ^{\infty}_{n=1}(-1)^{n+1}a_n=a_1-a_2+a_3-a_4...+a_n[/tex] is satisfies

(i) [tex]a_n +1\leq a_n[/tex] for all n

(ii) [tex]\lim_{\rightarrow \infty}a_n=0[/tex]

The formula for magnitude of error is

[tex]|R_n|=|s-s_n|\leq a_n+1[/tex]

Let [tex]a_n = \frac{(0.08)^n}{n}[/tex]

We can see [tex]\frac{(0.08)^n^+^1}{n} \leq \frac{(0,08)^n}{n}[/tex]

For all n ∈ N

That means [tex]b_{n+1}\leq b_n[/tex] for all   n ∈ N

[tex]\lim_{n \rightarrow \infty}a_n=\lim(\frac{(0.08)^n}{n} )\\\\=\frac{(0.08)^{\infty}}{\infty}[/tex]

[tex]\lim_{n\rightarrow \infty}a_n =0[/tex]

The alternating series estimation theorem is [tex]|R_s| = |s-s_n|\leq a_{n+1}[/tex]

After stop adding the term with n = 6

the series tells that the error is smaller than the term with a

Therefore

[tex]a_7 = \frac{(0.08)^7}{7} \\\\= \frac{20.97152}{7} \times 10^-^9\\\\=2.9959\times10^-^9[/tex]

the magnitude of the error is 2.9959 × 10⁻⁹

Answer:

Fractional probability of having 3 boys and 0 girls in a family for first 3 births is [tex]\frac{1}{8}[/tex].

Step-by-step explanation:

Let A be the event of birth of a boy.

Let B be the event of birth of a girl.

Probability of birth of a boy, P(A) [tex]= \frac{1}{2}[/tex]

Probability of birth of a girl, P(B) [tex]= \frac{1}{2}[/tex]

We have to find the probability of birth of 3 boys i.e. event A occurring 3 times in a succession. It is independent events i.e. do not have any dependency on occurrence of any event.

So, Required probability can be calculated just by multiplying P(A) for 3 times.

i.e.

[tex]P(E) = P(A) \times P(A) \times P(A)\\\Rightarrow \dfrac{1}{2} \times \dfrac{1}{2} \times \dfrac{1}{2}\\\Rightarrow \dfrac{1}{8}[/tex]

So, the probability of having 3 boys and 0 girls in the family is [tex]\frac{1}{8}[/tex].

x=34

Step-by-step explanation:

x+(x+12)+100=180

2x+12=80

2x=68

x=34

USE SUPPLEMENTARY!! STRAIGHT LINE= 180 degrees! :))

Answer:

[tex] \boxed{x \degree = 34\degree} [/tex]

Step-by-step explanation:

[tex] = > (x + 12) \degree + 100 \degree + x \degree = 180 \\ \\ = > x \degree + 12 \degree + 100 \degree + x \degree = 180 \degree \\ \\ = > 2x \degree + 112 \degree = 180 \degree \\ \\ = > 2x \degree = 180 \degree - 112 \degree \\ \\ = > 2x \degree = 68 \degree \\ \\ = > x \degree = \frac{68}{2} \degree \\ \\ = > x \degree = 34\degree[/tex]

Answer:

Step-by-step explanation:

The volume of a spherer is defined as

[tex]V=\frac{4}{3} \pi r^{3}[/tex]

Where [tex]r[/tex] is the radius and [tex]\pi \approx 3.14[/tex]

According to the proble, the diameter is 20 feet. By definition of radius,

[tex]r=\frac{d}{2}=\frac{20ft}{2} =10ft[/tex]

Replacing the radius in the volume formula

[tex]V=\frac{4}{3} \pi (10)^{3}[/tex]

[tex]V=4,187 \ ft^{3}[/tex]

Therefore, the volume of the sphere is 4187 cubic feet, approximately.

Answer:

A = $ 7,299.92

A = P + I where

P (principal) = $ 6,000.00

I (interest) = $ 1,299.92

Step-by-step explanation:

A = P(1 + r/n)^nt

Where:

A = Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

R = Annual Nominal Interest Rate in percent

r = Annual Nominal Interest Rate as a decimal

r = R/100

t = Time Involved in years, 0.5 years is calculated as 6 months, etc.

n = number of compounding periods per unit t; at the END of each period

Answer:

25 meters

Step-by-step explanation:

Imagine a segment extending vertically down from the left tree to the right tree.

That would make the segment be 25-10, or 15.

Then, we have a right triangle and we can solve for the hypotenuse, which is the length of the rope. (The bottom of the triangle is 20, and the leg is 15.)

We can use the pythag theorem: 15^2+20^2=c^2

c^2=225+400

c^2=625

c=25

Therefore, 25 meters

Answer:

[tex]4.91 in[/tex]

Step-by-step explanation:

a bucket has the form of a cylinder, which has the following formula for its volume:

[tex]V=\pi r^2h[/tex]

where r is the radius and h is the height.

Since we need to find the radius, we solve for r:

[tex]r^2=\frac{V}{\pi h}\\ \\r=\sqrt{\frac{V}{\pi h} }[/tex]

and since we know according to the problem that:

[tex]V=885in^3[/tex]

and

[tex]h=11.7in[/tex]

substituing these values:

[tex]r=\sqrt{\frac{885in^3}{(3.14)(11.7in)}}\\ \\r=\sqrt{\frac{885in^3}{36.738in}}\\\\r=\sqrt{24.0895in^2}\\\\r=4.908in[/tex]

the radius is: [tex]4.908in[/tex] which can be rounded to [tex]4.91 in[/tex]

Answer:

Slope = [tex]-\frac{1}{6}[/tex]

Step-by-step explanation:

Slope = [tex]\frac{Rise}{Run}[/tex]

Slope = [tex]\frac{6-10}{24-0}[/tex]

Slope = [tex]-\frac{1}{6}[/tex]

Answer:

-1/6

Step-by-step explanation:

Just use the formula Y2-Y1/X2-X1.

In this case if you substitute the coordinates of those numbers, then it would be 6-10/24-0 which is 24/-4 and if you simplify it, then you get the slope -1/6.

Answer:

21 people will win, so the profit will be £18

Step-by-step explanation:

0.35 x 60 = 21

21 x 2 = 42 (the amount of money to give away to prize winners)

If 60 people enter, she has £60. Subtracting £42 in winning payouts from this leaves her with a £18 profit.

Step-by-step explanation:

Answer:

[tex]((-\frac{1}{2}(x+y), -\frac{1}{2} (x-y) )[/tex]

Step-by-step explanation:

T(x , y) = (-x -y, -x +y)

T(1, 0) = (-1, -1) = -1(1 , 0) -1(0 , 1)

T(0, 1) = (-1, 1) = -1(1 , 0) +1(0 , 1)

Therefore,

[tex]T = \left[\begin{array}{ccc}-1&-1\\-1&1\end{array}\right][/tex]

|T| = [-1 -1] = -2

T is invertible

[tex]T^-^1 = -\frac{1}{2} \left[\begin{array}{ccc}1&+1\\+1&-1\end{array}\right] \\\\=\left[\begin{array}{ccc}-1/2&-1/2\\-1/2&1/2\end{array}\right][/tex]

Therefore,

[tex]T^-^1(x,y)=(-\frac{1}{2}x -\frac{1}{2} y,-\frac{1}{2} x+\frac{1}{2} y)[/tex]

[tex]((-\frac{1}{2}(x+y), -\frac{1}{2} (x-y) )[/tex]

The expression for the length of fencing to go around the outer edges is  10x+10.

Length of the rectangular field is given by x+7

and width is given by 4x-2

Length of fencing outer edges is equal to its perimeter.

Perimeter of a rectangle = 2(l+b)

=2(x+7+4x-2)

=2(5x+5)

=10x+10

Hence, the length of fencing outer edges is 10x+10

Answer:

80%

Step-by-step explanation:

We know that Evelyn paid off $24 of the $30. To find the percentage, we divide the part by the whole and then multiply by 100. The multiplying by 100 is optional, but it just makes the calculation easier. In this case, the part is 24 and the whole is 30, so our expression would be [tex]\frac{24}{30} * 100[/tex], or 80%. Hope this helps!

Answer:

[tex]\frac{3}{20}[/tex]

Step-by-step explanation:

Fraction of the total that is for corn (TC - Total corn):

[tex]TC=\frac{1}{4}[/tex]

fraction of the corn section that is for white corn (WC - white corn in the corn seccion):

 [tex]WC=\frac{3}{5}[/tex]

we need to find the fraction of the whole field that is for the white corn.

For this we need to find how much is [tex]\frac{3}{5}[/tex] out of the [tex]\frac{1}{4}[/tex] destinated to corn, and this will be the fraction of the total that is for white corn. We find this fraction by multiplying the fraction of corn ([tex]\frac{1}{4}[/tex]) by the fraction of white corn in the corn section ([tex]\frac{3}{5}[/tex]).

I will call the total fraction of white corn TWC, thus:

[tex]TWC=WC*TC=\\=\frac{3}{5} *\frac{1}{4} \\\\=\frac{3*1}{5*4} \\\\=\frac{3}{20}[/tex]

the answer is: [tex]\frac{3}{20}[/tex] of the whole field is planted with white corn

Answer:

The formula to calculate pressure at an altitude in this case is:

P = original pressure x (1 + rate of change)^(number of changing)

in which,

original pressure = 101 kilopascals

rate of change = -11.9% = - 0.119

number of changing = 2000/1000 = 2

=> P = 101 x (1 - 0.119)^2 = 78.39 kilopascals

Hope this helps!
