$(a) P= \frac{A}{e^{rt}} 

(b) e^{rt}= \frac{A}{P} 

ln e^{rt}= ln(\frac{A}{P}), 
rt= ln(\frac{A}{P}), t= \frac{ ln(\frac{A}{P})}{r}, or, t= \frac{ lnA - lnP}{r},

Determine

Luden [163]

Answer:

$\mu_{x} = 64, \sigma_{x} = 12.83$

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu_{x} = \mu$ and standard deviation $\sigma_{x} = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

$\mu = 64, \sigma = 77, n = 36$

$\mu_{x} = 64, \sigma_{x} = \frac{77}{\sqrt{36}} = 12.83$

Help me out friends

GrogVix [38]

Answer:

y = x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 1, thus

y = x + c ← is the partial equation

To find c substitute (5, 3) into the partial equation

3 = 5 + c ⇒ c = 3 - 5 = - 2

y = x - 2 ← equation of line

This is an example of an expansion. The original figure is enlarged using proportional reasoning.

Each side length is multiplied by 6 to get the new poster.
