Answer:

Step-by-step explanation:

The zeroes of a function is where its graph intercepts the x axis:

in this case it happens in these points:

(-6;0) , (-4;0) , (0;0) , (2;0) , (4;0)

The starting salaries of individuals with an MBA degree are normally distributed with a mean of $40,000 and a standard deviation

antiseptic1488 [7]

Answer:

$P(X>30000)=P(\frac{X-\mu}{\sigma}>\frac{30000-\mu}{\sigma})=P(Z-2)$

And we can find this probability using the complement rule and the normal standard distribution

$P(z>-2)=1-P(z$

Step-by-step explanation:

Let X the random variable that represent the starting salaries of individuals with a MBA of a population, and for this case we know the distribution for X is given by:

$X \sim N(40000,5000)$

Where $\mu=40000$ and $\sigma=5000$

We are interested on this probability

$P(X\geq 30000)$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

Using this formula we got:

$P(X>30000)=P(\frac{X-\mu}{\sigma}>\frac{30000-\mu}{\sigma})=P(Z-2)$

And we can find this probability using the complement rule and the normal standard distribution

$P(z>-2)=1-P(z$

You pick a card at random, put it back, and then pick another card at random. 2 3 4 5 What is the probability of picking a numbe

olga_2 [115]

Answer:

3/4 or a 75% chance

Step-by-step explanation:

Out of 4 cards ( 2 3 4 5), here are the cards greater than 3: 4, and 5. That leaves you with a 2/4 chance of drawing one of them. (2 cards, 4 in total).

Then, picking a 4 out of 4 cards is a 1/4 chance; since that is one card out of 4 total possibilities.

1/4 + 2/4 = 3/4. Or, a 75% chance.
