Solve the logarithmic equation. Be sure to reject any value that is not in the domain of the original logarithmic expressions. G

Karolina [17]

$\bf \textit{logarithm of factors}\\\\
log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)\\\\
-------------------------------\\\\
ln(x-6)+ln(x+10)=ln(x-15)
\\\\\\
ln[(x-6)(x+10)]=ln(x-15)\implies (x-6)(x+10)=x-15
\\\\\\
x^2-5x-6=x-15\implies x^2-6x+9=0
\\\\\\
(x-3)^2=0\implies \boxed{x=3}$

ok.. now, if we use that on say ln(x-15), we end up with $\bf ln(-12)\implies log_e(-12)$ .

now, there's no exponent whatsoever, that would give us a negative result for a base of "e", namely, x = 3 is NOT in the domain for ln(), so the system is inconsistent, or has no solution.

Fill in the blanks using the following choices: reject, fail to reject, sufficient, enough, not sufficient, not enough If the p

Nat2105 [25]

Answer:

FAIL TO REJECT

NOT ENOUGH

Step-by-step explanation:

Given a Pvalue of 0.32

Decision region :

When Pvalue < α ; Reject the Null and conclude that there is significant or enough evidence to accept the alternative hypothesis.

Otherwise, fail to reject reject the null and conclude that, there is not enough evidence to accept the alternative hypothesis

Therefore, for the scenario above, where Pvalue = 0.32

Possible α values are ; 0.1, 0.05, 0.01

For all α - values listed, the Pvalue is greater than α

Pvalue > α ; Hence, FAIL TO REJECT the Null.

Conclusion :

There is NOT ENOUGH evidence to support the alternative that the proportion of students who have ear infection at one school and the other is different.

Write your answer with no spaces and any fraction with “/“

Archy [21]

Answer:

The slope is 1/2

Step-by-step explanation:

Hi!

Disclaimer: Just for this response, I'm going to write it the same way you write a fraction out on paper just so it's easier to see.

First, you plot the two coordinates on the graph:

(0,0) and (2,1)

The formula for slope is $\frac{y1 - y2}{x1 - x2}$
