Answer:

<h3> x-intercepts: (-7, 0) and (7, 0)</h3><h3> y-intercept: (0, -49)</h3>

Step-by-step explanation:

x-intercepts: f(x) = 0

x² - 49 = 0

x² = 49

x = -7 ∨ x = 7

Points: (-7, 0) and (7, 0)

y-intecept: y = f(0)

f(0) = 0² - 49 = -49

Point: (0, -49)

The number of rookie cards in a variety pack of baseball cards is normally distributed with a mean of 3 cards and the standard d

Sergio039 [100]

Answer:

$z = \frac{2-3}{\frac{1}{\sqrt{10}}}=-3.163$

$z = \frac{4-3}{\frac{1}{\sqrt{10}}}=3.163$

$P(-3.163$

So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10

Step-by-step explanation:

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

$X \sim N(3,1)$

Where $\mu=3$ and $\sigma=1$

We select a sample size of n = 10 variety packs and we want to find this probability:

$P(2$

We can use the z score formula given by:

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

If we apply this formula to our probability we got this:

We can find the z score for 2 and 4 and we got:

$z = \frac{2-3}{\frac{1}{\sqrt{10}}}=-3.163$

$z = \frac{4-3}{\frac{1}{\sqrt{10}}}=3.163$

So we can find the probability with this difference

$P(-3.163$

And using the normal standard distirbution or excel we got:

$P(-3.163$

So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10
