Which expression is equivalent to log Subscript c Baseline StartFraction x squared minus 1 Over 5 x EndFraction?

Mathematics
1 answer:
Harrizon [31]2 years ago
3 0

The equivalent expression of \log_c(\frac{x^2 - 1}{5x}) is \log_c(x^2 - 1) - \log_c(5x)

<h3>How to determine the equivalent expression?</h3>

The logarithmic expression is given as:

\log_c(\frac{x^2 - 1}{5x})

The law of logarithm states that:

log(a) - log(b) = log(a/b)

This means that the expression can be split as:

\log_c(\frac{x^2 - 1}{5x}) = \log_c(x^2 - 1) - \log_c(5x)

Hence, the equivalent expression of \log_c(\frac{x^2 - 1}{5x}) is \log_c(x^2 - 1) - \log_c(5x)

How can you show that two objects are proportional with an equation
masha68 [24]
For an equation to be proportional, it must have no y intercept, and it must have a slope. So, 
<span>y=4x+4  This equation isn't proportional because it has a y-intercept (+4)
y=4x+2  </span>This equation isn't proportional because it has a y-intercept (+2)
y=4x      This equation is proportional because it has no y-intercept, and a                     slope.

A newsgroup is interested in constructing a 90% confidence interval for the proportion of all Americans who are in favor of a ne
Evgen [1.6K]

Answer:

a. With 90% confidence the proportion of all Americans who favor the new Green initiative is between 0.6290 and 0.6948.

b. If the sample size is changed, the confidence interval changes as the standard error depends on sample size.

About 90% percent of these confidence intervals will contain the true population proportion of Americans who favor the Green initiative and about 10% percent will not contain the true population proportion.

Step-by-step explanation:

We have to calculate a 90% confidence interval for the proportion.

The sample proportion is p=0.6619.

p=X/n=370/559=0.6619

The standard error of the proportion is:

\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.6619*0.3381}{559}}\\\\\\ \sigma_p=\sqrt{0.0004}=0.02

The critical z-value for a 90% confidence interval is z=1.6449.

The margin of error (MOE) can be calculated as:

MOE=z\cdot \sigma_p=1.6449 \cdot 0.02=0.0329

Then, the lower and upper bounds of the confidence interval are:

LL=p-z \cdot \sigma_p = 0.6619-0.0329=0.6290\\\\UL=p+z \cdot \sigma_p = 0.6619+0.0329=0.6948

The 90% confidence interval for the population proportion is (0.6290, 0.6948).

A researcher observes that, on average, the number of divorces in cities with major league baseball teams is larger than in citi
Leokris [45]

Answer: A

Step-by-step explanation:

Cities where there are major league baseball teams will have high population density. i.e densely populated

This is because baseball will attract several teams of players, coaches, lines men, instructors, spectators and supporters who would like participate in the game.

A major league attracts both local and international players and spectators thereby causing a mixed concentration of both citizens and non-citizens.

This therefore will accommodate several divorced citizens and non-citizens into the city.
