Equal expressions can be taken equal to an another variable. The system of equations representing the equation is $y = x + 3\\y = 4x + 8$

<h3>What is logarithm and some of its useful properties?</h3>

When you raise a number with an exponent, there comes a result.

Lets say you get

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

Some properties of logarithm are:

$log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})\\\\log_a(b^c) = c \times log_a(b)\\\\log_b(b) = 1\\\\ log_a(b) + log_b(c) = log_a(c)$

Log with base e = 2.71828... is written as $\ln(x)$ simply.

Log with base 10 is written as $\log(x)$ simply.

The given equation is:

$\log_4(x+3) = \log_2(2 +x)$

Adding $\log_2(4)$ on both the sides, we get:

$\log_2(4) + \log_4(x+3) =\log_2(4) + \log_2(2 +x) \\\\log_2(x + 3) = log_2(4(2+x))\text{\: \: \: (using first and last property listed)}\\\\x+3 = 8+4x = y(say)$

The, we get two equations as:

$y = x + 3\\y = 4x + 8$

This is the needed system of equations.

weeeeeb [17]

Answer:

The interval ( 1,8 ; 14,4 ) will contains 99,7 % of all values

Step-by-step explanation:

For Normal Distribution N ( μ ; σ ) the Empirical Rule establishes that in the intervals:

( μ ± σ ) we find 68,3 % of all values

( μ ± 2σ ) we find 95,4 % of all values

( μ ± 3σ ) we find 99,7 % of all values

Then we have a normal distribution N ( 8,1 ; 2,1 )

3*σ = 3* 2,1 = 6,3

And 8,1 - 6,3 = 1,8 8,1 + 6,3 = 14,4

Then the interval ( 1,8 ; 14,4 ) will contains 99,7 % of all values
