CAN YOU HELP ME PLZZZZZZZZZZZZZZZZZZZZZ?????????????????????????? I NEED HELP FAST
muminat

Answer:

2.86%

Step-by-step explanation:

assuming there is no replacement

There is a total of 6 envelopes

Since the question is asking for red, then green, then red, order is very important

The probability of a red is 3/7

Since we have selected 1 envelope, there are only 6 total envelopes left so the probability of a green is 1/6

Then we need a red again

Since we have selected 2 envelopes, one of which is red, there are only 5 total envelopes and 2 red envelopes so the probability of a red is 2/5

Now we multiply all of these so 3/7x1/6x2/5 = .02857142857

To find the percentage, you multiply by 100 so 2.857142857

Im pretty sure they want you to estimate it so 2.86% is what I would put but it depends on your teacher

How would I do the steps to solve this?
allsm [11]

Answer:

The maximum revenue is 16000 dollars (at p = 40)

Step-by-step explanation:

One way to find the maximum value is derivatives. The first derivative is used to find where the slope of function will be zero.

Given function is:

R(p) = -10p^2+800p

Taking derivative wrt p

\frac{d}{dp} (R(p) = \frac{d}{dp} (-10p^2+800p)\\R'(p) = -10 \frac{d}{dp} (p^2) +800 \ frac{d}{dp}(p)\\R'(p) = -10 (2p) +800(1)\\R'(p) = -20p+800\\

Now putting R'(p) = 0

-20p+800 = 0\\-20p = -800\\\frac{-20p}{-20} = \frac{-800}{-20}\\p = 40

As p is is positive and the second derivative is -20, the function will have maximum value at p = 40

Putting p=40 in function

R(40) = -10(40)^2 +800(40)\\= -10(1600) + 32000\\=-16000+32000\\=16000

The maximum revenue is 16000 dollars (at p = 40)

Jenifer bought 6 packages of hotdogs and 8 packages of rolls for $41.50. A package of rolls cost $0.85 less than a package of ho
kramer

Answer:

hotdogs 3.45

rolls 2.60

Step-by-step explanation:

6h + 8r = 41.5

r=h-.85

6h + 8(h-.85)=41.5

6h + 8h - 6.8 = 41.5

14h = 41.5 + 6.8

14h = 48.3

h=48.3/14

h=3.45

r=3.45-.85=2.6
