$\frac{y}{4} = - 3$

$y = - 3 \times 4$

$y = - 12$

Multiplication would be used.

A company sells widgets. The amount of profit y made by the company is related to the selling price of each widgets x by the giv

SCORPION-xisa [38]

Answer:

The maximum amount of profit is 32

Step-by-step explanation:

Given

$y=-x^2+64x-292$

Required

Determine the maximum profit

This is calculated by calculating the maximum of the function.

A quadratic function is of the form

$y = ax^2 + bx + c$

and its maximum is:

$Max = \frac{-b}{2a}$

So: $y=-x^2+64x-292$

We have that

$a = -1$

$b = 64$

$c = -292$

$Max = \frac{-b}{2a}$

$Max = \frac{-64}{2 * -1}$

$Max = \frac{-64}{-2}$

$Max = 32$

<em>Hence, the maximum amount of profit is 32</em>

Answer:

(a) x: Ferris wheel once; y: roller coaster once

Step-by-step explanation:

The coefficients of x and y are both 1 in the equation representing the statement ...

"if he rides them each once, it takes 14 minutes total."

That tells you that x and y represent the times for one ride.

The coefficient of x is 6 in the equation representing the statement ...

"he rides the Ferris wheel 6 times ..."

This tells you the variable x represents the Ferris wheel ride time. It is further confirmation that x represents the time for one ride.

Alligators captured in Florida are found to have a mean length of 2 meters and a standard deviation of 0.35 meters. The lengths

STALIN [3.7K]

Answer:

The correct option is (d). 2.15 meters.

Step-by-step explanation:

According to the given scenario, the approximate length of an alligator at the 67th percentile is as follows:

The length of an alligator is $X \sim N(2,0.35)$ .

Let us assume the $P_{67}$ be the 67th percentile

$P(X$

$\frac{P_{67 - 2 }}{0.35} = 0.44\\\\P_{67} = 2.154$

Hence, the correct option is (d). 2.15 meters
