<h3>The needed equation representing the profit y is represented in the option B.</h3><h3>B. y = -x² + 50 x - 300 </h3>

Step-by-step explanation:

Here, the given options are incomplete.

A. y² = 4 x² - 100

B. y = -x² + 50 x - 300

C. x = -y² + 60 y - 400

D. x ² = - 6 y² + 200

The number of items sold by the company = x

The profit ( in thousands) is represented as = y

Now, here as we are looking for the equation representing profit (y)

So, we can disregard the equations which has terms (x) and ( x²) in left.

⇒The equations in the options C and D are eliminated.

Similarly, again we are looking for the equation for Profit , not (profit)².

So,we can disregard the equation which has terms (y²) in left side.

⇒The equation in the options A is eliminated.

Hence, the needed equation representing the profit y is represented in the option B.

B. y = -x² + 50 x - 300

For a standard normal distribution, find the approximate value of p (negative 0.78 less-than-or-equal-to z less-than-or-equal-to

topjm [15]

The approximate value of P(-0.78 ≤ Z ≤ 1.16) is obtained being 0.6593

<h3>How to get the z scores?</h3>

If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.

If we have $X \sim N(\mu, \sigma)$

(X is following normal distribution with mean $\mu$ and standard deviation $\sigma$ )

then it can be converted to standard normal distribution as

$Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)$

(Know the fact that in continuous distribution, probability of a single point is 0, so we can write

$P(Z \leq z) = P(Z < z) )$

Also, know that if we look for Z = z in z-tables, the p-value we get is

$P(Z \leq z) = \rm p \: value$

For this case, we have to find:

$P(-0.78\leq Z \leq 1.16)$

It can be rewritten as:

$P(-0.78\leq Z \leq 1.16) = P(Z \leq 1.16) - P(Z < -0.78) \\P(-0.78\leq Z \leq 1.16) = P(Z \leq 1.16) - P(Z \leq -0.78)$

The p-values for Z = 1.16 and Z = -0.78 from the z-table is found as 0.8770 and 0.2177 respectively, and therefore, we get:

$P(-0.78\leq Z \leq 1.16) = P(Z \leq 1.16) - P(Z \leq -0.78)\\P(-0.78\leq Z \leq 1.16) = 0.8770 - 0.2177 = 0.6593$

Thus, the approximate value of P(-0.78 ≤ Z ≤ 1.16) is obtained being 0.6593
