Which are possible first steps in solving the equation 4x + 3 = 187

Answer:

Step-by-step explanation:The only one you probably can never do is B. It get's you no where. The way A is written, it is not much help to write 18 in base 2. So A and B both won't work. The common logs and the natural logs will both work

Log(4^(x + 3)) = Log(18)

(x + 3) Log(4) = log (18)

(x + 3) * 0.6021 = 1.2553

x + 3 = 1.2553/0.6021

x + 3 = 2.08496

Now all you need do is subtract 3 from both sides. The natural logs will give you the same answer.

You could take base-4 logs of both sides and it is a possible first step, but d and e are much more efficient. You have to change both sides to base 4 before you can proceed. This one is kind of iffy. It does say possible first steps.

Rewrite in simplest radical form, thx :)

Aleks [24]

Answer:

The answer is

$\sqrt[3]{ {x}^{2} }$

Step-by-step explanation:

$\frac{ {x}^{ \frac{5}{6} } }{ {x}^{ \frac{1}{6} } }$

Since they have the same base and are dividing we can use the rules of indices

That's

subtract the exponents

So we have

${x}^{ \frac{5}{6} - \frac{1}{6} }$

${x}^{ \frac{4}{6} }$

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

Rewriting it in radical form

We have the final answer as

$\sqrt[3]{ {x}^{2} }$

Hope this helps you

Find the simple interest. <br> Round to the nearest cent. <br><br> $7,800 at 9.25% for 4 months

murzikaleks [220]

Answer:

The simple interest for 4 months = Rs 240

Step-by-step explanation:

formula:-

simple interest I = [PNR]/100

P - Principle amount

N - Number of years

R - Rate of interest

It is given that, $7,800 at 9.25% for 4 months

<u>To find the simple interest for 1 year</u>

I = [PNR]/100

I = [7800*1*9.25]/100 = 721.5

<u>To find the simple interest for 4 months</u>

4 months = (1 year )/3

4 months interest = 721.5/3 =240.5 ≈ 240

Therefore the simple interest for 4 months = Rs 240

Which of the following statements regarding a binomial experiment is false, where n is the number of trials, and p is the probab

tatuchka [14]

Answer:

A. The standard deviation is np(1 - p).

Step-by-step explanation:

The variance of the number of successes/failures is measured by (σ2x) is n * P * ( 1 - P ).

The standard deviation (σx) is square root of [ n * P * ( 1 - P ) ]

The mean is np.
