$\bf log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)

% Logarithm of exponentials
log_{{ a}}\left( x^{{ b}} \right)\implies {{ b}}\cdot log_{{ a}}(x)\\\\

log_b(xy^2z^{-6}\implies log_b(x)+log_b(y^2)+log_b(z^{-6})
\\\\\\log_b(x)+2log_b(y)-6log_b(z)$

now, the one below that, which is equivalent to that? well, just look above it

Find a1, for the given geometric series. Round to the nearest hundredth if necessary. Sn= 86,830, r= 2.2, n=4

larisa86 [58]

Answer:

4,646.30

Step-by-step explanation:

The sum of n terms of geometric sequence can be calculated using formula

$S_n=\dfrac{a_1(1-r^n)}{1-r}$

In your case,

$S_n=86,830\\ \\r=2.2\\ \\n=4\\ \\a_1=?$

Substitute into the formula:

$S_4=\dfrac{a_1(1-2.2^4)}{1-2.2}\\ \\86,830=\dfrac{a_1(1-23.4256)}{-1.2}\\ \\-104,196=a_1(-22.4256)\\ \\22.4256a_1=104,196\\ \\a_1=\dfrac{104,196}{22.4256}\approx 4,646.30$

If a car agency sells 50% of its inventory of a certain foreign car equipped with side airbags, ﬁnd a formula for the probabilit

antiseptic1488 [7]

Answer:

Let X the random variable of interest "number of cars with side airbags among the next 4", on this case we now that:

$X \sim Binom(n=4, p=0.5)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And the distribution is given by:

$P(X)= (4CX) (0.5)^x (1-0.5)^{4-x}$

With $X=0,1,2,3,4$

Step-by-step explanation:

Previous concepts

A Bernoulli trial is "a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted". And this experiment is a particular case of the binomial experiment.

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest "number of cars with side airbags among the next 4", on this case we now that:

$X \sim Binom(n=4, p=0.5)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And the distribution is given by:

$P(X)= (4CX) (0.5)^x (1-0.5)^{4-x}$

With $X=0,1,2,3,4$

What is the initial value in the equation f(x) = 350(1 - 0.12)^x? *

kvasek [131]

Given:

The function is:

$f(x)=350(1-0.12)^x$

To find:

The initial value of the function.

Solution:

We have,

$f(x)=350(1-0.12)^x$

The value of the function at x=0 is called the initial value of the function.

For x=0, we get

$f(0)=350(1-0.12)^0$

$f(0)=350(0.88)^0$

Clearly 0.88 is a non zero number and zero to the power of a non zero number is always 1.

$f(0)=350(1)$

$f(0)=350$

Therefore, the initial value of the function is 350.
