There are 2415 females in the country.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

There are 3450 people in a country.

It was recently estimated that females outnumber males by seven to three.

That means,

70% are the females.

So, the number of females,

= 70% of, 3450

= 70 x 3450 / 100

= 2415.

Therefore, 2415 females are in the country.

Answer:

5/18

Step-by-step explanation:

Step one

Given data

5 monkeys,

4 giraffes,

6 elephants, and

3 tigers.

Step two

Given the sample space

S =(5, 4,6,3) = 5+4+6+3=18

Step three

the probability of pulling a card at random when picking up a card is

Pr(monkey) = 5/18

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!

Step-by-step explanation:

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

s(x) = 2x+1

r(6) / s(6)

r(6) = 3(6)-1

s(6) = 2(6)+1

Putting r(6)/ s(6)

3(6)-1

Answer:

[tex]L=\dfrac{g}{4\pi^2 f^2}[/tex]

Step-by-step explanation:

The equation to calculate the period of a simple pendulum is: [tex]T=2\pi \sqrt{\frac{L}{g} }[/tex]

Where:

Likewise, Frequency (f) of the pendulum [tex]f=\frac{1}{T}[/tex] therefore [tex]T=\frac{1}{f}[/tex]

We want to express L in terms of g and f.

From

[tex]T=2\pi \sqrt{\frac{L}{g} }[/tex]

[tex]T=\frac{1}{f}[/tex]

[tex]\frac{1}{f}=2\pi \sqrt{\frac{L}{g} }\\$Divide both sides by 2\pi\\\dfrac{1}{2\pi f}=\sqrt{\dfrac{L}{g} }\\$Square both sides\\\left(\dfrac{1}{2\pi f}\right)^2=\dfrac{L}{g}[/tex]

[tex]\dfrac{1}{4\pi^2 f^2}=\dfrac{L}{g} \\$Multiply both sides by g\\Therefore: L=\dfrac{g}{4\pi^2 f^2}[/tex]
