To answer the problem above, divide the numerical portion and the exponential portion of the given numbers. 4.5 divided by 9 is 0.5. Furthermore, 10^3 divided by 10^7 is 10^-4. The answer is 
                    
                                            0.5 x 10^-4

This may still be written in a standard form,
 
                                               5 x 10^-5

Thus, the answer is <em>5 x 10^-5</em>.

Answer:

The required solution is \frac{(4.5 \times 10^3)}{(9 \times 10^7)}=5\times 10^{-5}

Step-by-step explanation:

Given : Quotient  \frac{(4.5 \times 10^3)}{(9 \times 10^7)}

To find : Simplify the quotient and write your answer in scientific notation?

Solution :

The given quotient is \frac{(4.5 \times 10^3)}{(9 \times 10^7)}

We know, \frac{x^a}{x^b}=x^{a-b}

Now, we solve the quotient

=\frac{(4.5 \times 10^{3-7})}{9}

=0.5 \times 10^{-4}

The resultant in the scientific notation is =5 \times 10^{-5}

So, The required solution is \frac{(4.5 \times 10^3)}{(9 \times 10^7)}=5\times 10^{-5}

Heights for women are bell-shaped with a mean of 65 inches and standard deviation of 2.5 inches. If a random sample of 16 women
loris [4]

Answer:

μ= 65 inches; σ= 0.625 inch

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed(bell-shaped) random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

\mu = 65, \sigma = 2.5

By the central limit theorem, the sample of 16 will have:

\mu = 65, \sigma = \frac{2.5}{\sqrt{16}} = 0.625

So the correct answer is:

μ= 65 inches; σ= 0.625 inch

- The dog trainer gives treats to 8 dogs as
elena55 [62]

Answer:

36 Treats

Step-by-step explanation:

The dog trainer started with a bag of 60 treats.

The dog trainer gives treats to 8 dogs with 3 treats meaning 8x3= 24

The trainer gave a total of 24 treats to the 8 dogs.

If the trainer had 60 treats at the start minus 24 (60-24=36).

That means the trainer now has a total of 36 treats left.

Oakville is a fungal disease that infects oak trees scientists have discovered that a single tree in a small forest is infected
Galina-37 [17]

Answer:

I solved part a

To solve this question, we need to solve an exponential equation, which we do applying the natural logarithm to both sides of the equation, getting that it will take 7.6 years for for 21 of the trees to become infected.

PART C

The logarithmic model is: g(x)= in x/0.4

We are given an exponential function, for the amount of infected trees f(x) after x years.To find the amount years needed for the number of infected trees to reach x, we find the inverse function, applying the natural logarithm.
