Suppose that you own a store that sells a particular stove for $1,000. You purchase the stoves from the distributor for $800 eac

h. You believe that this stove has a lifetime which can be faithfully modeled as an exponential random variable with a parameter of lambda = 1/10, where the units of time are years. You would like to offer the following extended warranty on this stove: if the stove breaks within r years, you will replace the stove completely (at a cost of $800 to you). If the stove lasts longer than r years, the extended warranty pays nothing. Let $C be the cost you will charge the consumer for this extended warranty. For what pairs of numbers (C,r) will the expected profit you get from this warranty be zero. What do you think are reasonable choices for C and r? Why?

Answer:

x³/4z²

Step-by-step explanation:

Invert and multiply:

48x^5y²/12z^5 x z³/16x²y²=

(48x^5y²)(z³)/(16x²y²)(12z^5)

the y² cancel out

48÷16=3 (on top)

x^5÷x²=x³

12z^5/z³=z²(on bottom)

This leaves a 3x³ on top and 12z² on the bottom.  3÷12=4 (on bottom):

3x³/12z²

x³/4z²

Im so lost what the answer is
Rainbow [258]

Answer:

Unfortunately, we can't do anything with 41 as it has no factors. Since 3\sqrt{41} is already simplified, try submitting that as your answer. If that doesn't work then try un-doing their steps and get rid of the 3:

3\sqrt{41}

\sqrt{41(9)}

\sqrt{369}

Hope this helps!

Use the Pythagorean theorem to answer 4 5 and 6
Lady bird [3.3K]
Okay, the formula for this would be


a^{2} + b^{2} = c^{2}


Lets start with 4.

7^{2} + 25^{2} = c^{2}

Simplify.

49 + 625 = c^{2}

674 = c

c = \sqrt{674}
 
c = 25.96

Which is ≈ 26
