Answer: The Inverse variation

Step-by-step explanation:

The phrase “ y varies inversely as x” or “ y is inversely proportional to x” means that as x gets bigger, y gets smaller, or vice versa. This concept is translated in two ways. yx = k for some constant k, called the constant of proportionality.

The product of 3 consecutive odd numbers is 3,315. Enter a simplified expression for finding the numbers. Let n be the first odd

grin007 [14]

Answer:

$n^3+6n^2+8n=3315$

Step-by-step explanation:

Let n be the first odd number.

The 2nd consecutive odd number would be $n+2$ and 3rd consecutive odd number would be $n+2+2=n+4$ .

We have been given that the product of 3 consecutive odd numbers is 3,315. The product of 3 consecutive odd numbers would be $n(n+2)(n+4)$ .

Now we will equate the product with 3315 as:

$n(n+2)(n+4)=3315$

Let us simplify the left side of equation.

$(n\cdot n+n\cdot 2)(n+4)=3315$

$(n^2+2n)(n+4)=3315$

Now, we will apply FOIL to find the product of left side as:

$n^2\cdot n+n^2\cdot 4+2n\cdot n+2n\cdot4=3315$

$n^3+4n^2+2n^2+8n=3315$

$n^3+6n^2+8n=3315$

Therefore, our required equation would be $n^3+6n^2+8n=3315$ .

Jeannie is an experienced business traveler, often traveling back and forth from San Francisco to the East Coast several times p

lesya692 [45]

Answer:

The probability that Jeannie will miss her flight because her total time for catching her plane exceeds one hour is 0.0026.

Jeannie should leave her office 55 minutes early.

Step-by-step explanation:

Let X = time it requires Jeannie to catch her plane.

The random variable X is normally distributed, $N(46, 5)$ .

Compute the probability that Jeannie will miss her flight because her total time for catching her plane exceeds one hour as follows:

$P(X>60)=P(\frac{X-\mu}{\sigma} >\frac{60-46}{5} )\\=P(Z>2.8)\\=1-P(Z$

The probability that Jeannie will miss her flight because her total time for catching her plane exceeds one hour is 0.0026.

Now, it is provided that Jeannie has 96% chance of catching her flight if she reaches under x minutes.

That is, P (X < x) = 0.96.

Compute the value of x as follows:

$P(X$

**Use the z-table to compute the value of z.

The value of z is 1.751.

Compute the value of x as follows:

$z=\frac{x-46}{5}\\ 1.751=\frac{x-46}{5}\\x=46+(1.751\times5)\\=54.755\\\approx 55$

Thus, Jeannie should leave her office 55 minutes early.
