Explain the process and the properties you have to use to solve the logarithmic equation: log(3)x + log(3)4 - 2 log(3)3 = 2

Akimi4 [234]

81/4

Step-by-step explanation:

$log_{3}( \frac{4x}{{3}^{2} } ) = 2$

${3}^{2} = \frac{4x}{ {3 }^{2} }$

9=4x/9

81=4×

x=81/4

adding logs means elements are multiplied, subtracting means divide. number in front of log is raised to power

base of log is raised to power of element after =

element in log is then equal to log base raised to power

solve resulting equation

A test consists of 100 multiple choice questions, each with five possible answers, only one of which is correct. Find the mean a

TEA [102]

Answer: Mean = 20 and standard deviation = 4

Step-by-step explanation:

Let x represents the success of getting the correct answer.

Here, the total number of trials(n) = 100

The probability of getting the correct answer, p = 1/5

Thus, the mean of the number of correct answer,

$\mu_x= np$

$\mu_x= 100\times 1/5$

$\mu_x= 20$

Now, the standard deviation, $\sigma_x= \sqrt{n\times p\times (1-p)}$

$\sigma_x= \sqrt{100\times 1/5\times 4/5}$

$\sigma_x= \sqrt{16}$

$\sigma_x= 4$

Thus, First option is correct.

I need help showing steps to solve 36v-12=12

Ad libitum [116K]

36v - 12 = 12 .....add 12 to both sides
36v - 12 + 12 = 12 + 12...simplify
36v = 24...divide both sides by 36
(36/36)v = 24/36
v = 2/3 <===

At the newest animated movie, for every 9 children, there are 4 adults. There are a total of 39 children and adults at the movie

WARRIOR [948]

For every 9 children, there are 4 adults.
If there are 39 children and adults, we can work backwards to find the answer.

Lets start by multiplying 9. Lets do 3. 9 x 3 = 27.
Ok, now we have an estimate of 27 Children, now all we have to do is multiply the number of adults by 3.
Now we can multiply 4 x 3. 4 x 3 = 12. Now we have the number of children and adults.
Now lets add these together. 12 + 27 = 39! Perfect! Now we know that there are 27 children, and 12 adults.

Hope this helps!!
