Answer:

Bk = 65

Step-by-step explanation:

BK as we can see is 4x + 1

If two triangles are similar, the ratio of the corresponding sides are the same

Thus;

2x+7/27 = 4x + 1/45

45(2x + 7) = 27(4x + 1)

90x + 315 = 108x + 27

108x-90x = 315-27

18x = 288

x = 288/18

x = 16

From the question;

BK = 4x + 1

BK = 4(16) + 1

BK = 64 + 1

BK = 65

Condense the following logarithm: 5log_4(a) - 6log_4(b)

grin007 [14]

Hi there! We are given the expression:

$\large \boxed{5 log_{4}(a) - 6 log_{4}(b) }$

To condense or simplify the following logarithm. You have to remember these properties:

Properties - Logarithm

$\large{ log_{b}(a)^{n} = n log_{b}(a) } \\ \large{ log_{b}(a) - log_{b}(c) = log_{b}( \frac{a}{c} ) }$

These two properties are what we need for our problem. Therefore,

$\large{ log_{4}(a)^{5} - log_{4}(b)^{6} }$

We use the log_b(a)^n = nlog_b(a) property to convert in the form above. Next, we use the second property.

$\large{ log_{4}( \frac{ {a}^{5} }{ {b}^{6} } ) }$

Answer

log base 4 of (a^5/b^6) is our simplifed form.

Any questions can be asked through comment as I may reply soon. Thanks for using Brainly! Have a good day and happy learning! :)

Solution -

A student who was skeptical about this value decided to conduct a survey by randomly sampling 36 students. On average, the sampled students slept 6.6 hours per night.

The sample mean is the average of the 36 sampled students, which is 6.6 hours. So 6.6 represents the sample mean.

College newspaper stated that college students get an average of 7 hrs of sleep each night.

The claimed population mean is the stated average from the newspaper article, which is 7 hrs. So 7 represents the claimed population mean.
