Answer:

B. negative slope

Step-by-step explanation:

There are 4 types of slope:

Horizontal line: slope is 0

Vertical line: there is no slope

Diagonal line goes up to the right: positive slope

Diagonal line goes down to the right: negative slope

In this case, you have a diagonal line that goes down to the right, so the slope is negative.

Which point do the graphs of f and g have in common?

pickupchik [31]

The point that the graphs of f and g have in common are (1,0)

<h3>How to get the points?</h3>

The given functions are:

f(x) = log₂x

and

g(x) = log₁₀x

We know that logarithm of 1 is always zero.

This means that irrespective of the base, the y-values of both functions will be equal to 0 at x=1

Therefore the point the graphs of f and g have in common is (1,0).

Suppose a simple random sample of size n is drawn from a large population with mean mu and standard deviation sigma. The samplin

Sidana [21]

Answer:

$X \sim N(\mu,\sigma)$

Where $\mu$ the mean and $\sigma$ the deviation

Since the distribution for X is normal then we can conclude that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

$\mu_{\bar X} = \mu$

$\sigma_{\bar X}= \frac{\sigma}{\sqrt{n}}$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:

$X \sim N(\mu,\sigma)$

Where $\mu$ the mean and $\sigma$ the deviation

Since the distribution for X is normal then we can conclude that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

$\mu_{\bar X} = \mu$

$\sigma_{\bar X}= \frac{\sigma}{\sqrt{n}}$

If 60% of A is 20% of B, then B is what percent of A?<br> a. 3%<br> b. 30%<br> c. 200%<br> d. 300%

aleksley [76]

Answer:

d. 300%

Step-by-step explanation:

The given relation is ...

60%·A = 20%·B

Dividing by 20%, we see that ...

3·A = B

Of course, 3 = 3×100% = 300%, so B is 300% of A.

Which shows one way the equation can be represented in words?

sdas [7]

Answer:

Step-by-step explanation: Six less than a number is the same as one and four-tenths. The answer is this because a number represents z. When less is used in a word problem it almost always means subtract. Same as means equal to.
