Answer:

The total plots of vegetable cloud will be: 19

Step-by-step explanation:

From the question statement, it is clear that the cloud has [tex]8\frac{4}{15}[/tex] plots of pechay, [tex]5\frac{1}{3}[/tex] plots of eggplants and [tex]5\frac{2}{5}[/tex] plots of okra.

so, Just add all the plots to get the total plots of the vegetable cloud.

i.e.

[tex]8\frac{4}{15}+5\frac{1}{3}+5\frac{2}{5}=\frac{124}{15}+\frac{16}{3}+\frac{27}{5}[/tex]

                       [tex]=\frac{124}{15}+\frac{80}{15}+\frac{81}{15}[/tex]

                       [tex]=\frac{124+80+81}{15}[/tex]

                       [tex]=19[/tex]

Therefore, the total plots of vegetable cloud will be: 19

Answer:

a) The mean of the probability distribution = 0.6

b) The variance of the probability distribution = 0.3

c) The standard deviation of the probability distribution = 0.5

Step-by-step explanation:

a) Data and Calculations:

number of dogs per household in a small town

Dogs   Probability  Expected  Mean Diff    Mean Diff.

                               Value                            Squared

0          0.650           0               -0.569         0.32376

1           0.216            0.216        -0.353          0.12461

2         0.087            0.174         -0.395          0.15603

3          0.026            0.078       -0.491            0.24108

4          0.014             0.056       -0.513           0.26317

5          0.009          0.045       -0.524           0.27458

The mean =           0.569 (Sum of expected value)                          

Variance = mean of squared differences = 0.27665 (1.38323/5)

Standard deviation = square root of variance = 0.526 = 0.5

The mean, variance and standard deviation of the considered probability distribution are evaluated to be:

Supposing that the considered random variable is discrete, we get:

[tex]Mean = E(X) = \sum_{\forall x_i} f(x_i)x_i\\\\Variance = Var(X) = (\sum_{\forall x_i} f(x_i)x^2_i) - (E(X))^2\\[/tex]

As standard deviation is positive root of variance, thus,

[tex]\sigma = \sqrt {Var(X)}[/tex]

where [tex]x_i; \: \: i = 1,2, ... ,n[/tex] is its n data values

and  [tex]f(x_i)[/tex] is the probability of  [tex]X = x_i[/tex]

For this case, let we suppose that:

X = number of dogs per household in the considered town.

Then we have the probability distribution for values of X as:

Number of dogs     Probability

              0                  0.650

              1                   0.216

              2                  0.087

              3                  0.026

              4                  0.014

              5                  0.009

Thus, we get:

Mean of X : E(X) = [tex]0 \times 0.650 + 1 \times 0.216 + 2 \times 0087 + 3 \times 0.026 + 4 \times 0.014 + 5 \times 0.009 = 0.569[/tex]

Variance of X:

Var(X) =

[tex](0^2 \times 0.650 + 1^2 \times 0.216 + 2^2 \times 0.087 + 3^2 \times 0.026 + 4^2 \times (0.014)\\ + 5^2 \times (0.009)) - (0.569)^2 \approx 0.923[/tex]

Standard deviation of X = [tex]\sigma = \sqrt {Var(X)} \approx \sqrt{0.923} \approx 0.96[/tex]

Thus, the mean, variance and standard deviation of the considered probability distribution are evaluated to be:

Answer:

It's B - The graph includes a compression

and D - The graph is reflected across the x-axis

Step-by-step explanation:

I got those right

B is right because f(ax) if a is greater than 1, then it includes a horizonal compression and 1/4x = f(4x)

D is right because -f(x) reflects across the x-axis. -f(x)= -1/x.

So -f(4x) = -1/4x

Answer: c

Step-by-step explanation: the function is linear

Answer:

Yes that is correct. B is correct.

Step-by-step explanation:

When you plug 0 in for x, the result is 3.

When you plug 1 in for x, the result becomes 1.

The equation matches up correctly.

f(x) = -2x + 3

You got it right. Try to substitute x values in there to check your answer.

Here's an example

f(x) = -2x + 3

f(1) = -2(1) + 3 = -2+3 = 1

Answer:

It would take the company 47 days to be at half capacity.

Step-by-step explanation:

From the question, it is stated that the number of employees doubles in size everyday. This implies that the current day capacity is equal to the previous day capacity. This can be written in a mathematical form as follows:

Current day capacity = Previous day capacity * 2 ......................... (1)

We can assume that the current day capacity which is 48th day in this question is equal to 100 employees. That is;

Current day capacity = 48th day capacity = 100

Substituting this into equation (1) above and solve for the previous day capacity, we have:

100 = Previous day capacity * 2

Previous day capacity = 100 / 2 = 50

Since 50 is half of 100 and the previous day is 47th day, it therefore implies that It would take the company 47 days to be at half capacity.

Answer:

No real solutions

Step-by-step explanation:

Use the discriminant formula, D = b² - 4ac

D = b² - 4ac

Plug in b, a, and c:

D = b² - 4ac

D = (8)² - 4(1)(20)

D = 64 - 80

D = -16

Since the discriminant is negative, there are no real solutions

Since the solution is a complex value, hence the equation has no real solutions

Givne the quadratic expression x²+8x+20 = 0

Factorizing the function

x²+8x+20 = 0

x = -8±√8²-4(20)/2

x = -8±√64-80/2

x = -8±√-16/2

x = -8±4i/2

x = -4±2i

Since the solution is a complex value, hence the equation has no real solutions

Answer:

4.5 feet of snow = 27 inches H2o. Please read the explanation for better details

Step-by-step explanation:

if 0.5 feet of snow melts into 2 inches of water, then that means that 6 inches of snow melts into 2 inches of water. This means that for every 2 inches of snow you melt, it will become 1 inch of water. If 4.5 ft = 54 inches, you simply divide by 2, getting your answer of 27 inches of snow. Hope this helps! :)

Answer:

  Once upon a time a troll was walking down a deep dark hallway, there was no light anywhere that he could see and he was starting to get scared of what could happen to him. But then out of the blue he saw something, something was would change his life forever, he saw a pigeon. Now you might think "Oh, a pigeon, how could that have changed his life?' Now the answer is kind of mundane but is deeper than you might think. The simple answer as to why the pigeon would change his life is because it gave the troll hope, hope that there is an exit. You see, the troll thought if the pigeon found there way into this pitch black hallway, then there must be a way in and hence a way out.

  Now listen here, there's something that I wasn't telling you at the beginning of the story about the pigeon, the pigeon was also glowing. This is very useful obviously because it gave the troll some kind of light. Again, it gave the troll hope. Now, being a troll you might think that he would just snatch the pigeon and hold it for light, but this troll wasn't like other trolls, he had the capability to think before he used brute force to change something. So what the troll though was "If I just follow the pigeon then it might lead me to the exit because they have natural navigation in their brains"

 Let's skip a while into the future, the troll followed and followed the pigeon for what felt like days, but in reality it was more like 3 hours. But then, the troll saw something that he thought he would never see again; sun light. As soon as the troll saw this, he started running and running towards the light, but as fast as he was running, the light seemed to get farther and farther away from him, then... POOF the troll was gone...

  The troll found himself in a very lit up room, almost pure white all around him, which scorched his eyes because he was just in a pitch black room for hours. His ears were ringing and he was in pain, after a while all of that stopped, he was able to see clearly, he felt great, and his ears stopped ringing. What he saw was a very tall thin figure looking down at him from a room of pure white. The figure bent their neck and got right in the trolls face. The figure brought his left hand up to the trolls face, right next to his ear and snapped. The sound of a monstrous click sound right in the trolls ears hurt. The troll jumped back in fear but as soon as the click happened he saw a thing in his vision, a thing he new wasn't actually in the real world as it seemed to follow his eyes where ever he looked. It was, now i know this might sound stupid, I'm not here to imagine a story, I'm simply here to reenact the story of the troll. What he saw was a math problem, a grid was in his vision. It was a 4 by 6 grid.

 The tall shadow figure was now back where the troll saw him originally, he was no longer bent and he seemed to not have arms anymore, just a tall dark figure with a cloak. The troll then began to hear a voice which seemed to come from everywhere. It was a deep voice that was very muffled, it said "Do this math problem and go back to your world. Get it correct and everything will go back to normal, but fail; and I'll have your soul" The troll was about to have an adventure of a lifetime...
