A poll conducted the day before the student- body presidential election at a midwestern university showed that 53.9 percent favored Mario, the rest favoring Yin Ling. The margin of error was 4.2 percentage points. Should Yin Ling have conceded the election?

**Answer:**

No

**Step-by-step explanation:**

The confidence interval of the percentage of people that favored Mario = number of votes favoring Mario ± Margin of error

The confidence interval = 53.9% ± 4.2% = (49.7%, 58.1%)

This means that between 49.7% to 58.1% of the people would have voted for Mario.

Hence Yin Ling would not have won the election, since there is a probability that 50% would have voted for Mario

The annual gas bill for a town household are considered to be normally distributed with a mean of $ 1130 and a standard deviation of $ 150. If one household is randomly selected, what is the probability that the gas bill will be between $900 and $1100?

**Answer:**

The probability is [tex]P(900 < X < 1100) = 0.358102[/tex]

**Step-by-step explanation:**

From the question we are told that

The population mean is [tex]\mu = \$ 1130[/tex]

The standard deviation is [tex]\sigma = \$ 150[/tex]

Generally the probability that the gas bill will be between $900 and $1100 is mathematically represented as

[tex]P(900 < X < 1100) = P(\frac{900 - 1130 }{150 } < \frac{X - \mu}{\sigma } < \frac{1100 - 1130 }{150 } )[/tex]

=> [tex]P(900 < X < 1100) = P(-1.533 < \frac{X - \mu}{\sigma } < -0.2 )[/tex]

Generally [tex]\frac{X - \mu}{\sigma } = Z (The\ standardized \ value \ of \ X)[/tex]

So

[tex]P(900 < X < 1100) = P(-1.533 < Z< -0.2 )[/tex]

[tex]P(900 < X < 1100) = P( Z< -0.2 ) - P(Z < -1.533)[/tex]

From the z table

[tex]P(Z < -0.2 ) = 0.42074[/tex]

and

[tex]P(Z < -1.533) = 0.062638[/tex]

So

[tex]P(900 < X < 1100) = 0.42074 - 0.062638[/tex]

=> [tex]P(900 < X < 1100) = 0.358102[/tex]

**Answer:**

I cant see the equation that well, but i got 5/16

**Step-by-step explanation:**

Hope this helps!

**Answer:**

I got C) 1 and 1/4

**Step-by-step explanation:**

-0.5 + 0.75 = 0.25

1/5 = 0.20

0.25 divided by 0.20 would be over 1 because a fraction divided by another fraction brings the number while a whole number divided by a fraction would bring the number down.

0.25 divided by 0.20 = 1.25

A concert organizer learned from a market survey that when the admission price is $30, there is an average attendance of 800 people. For every $1 drop in price, there is a gain of 20 customers. Each customer spends an average of $5 on concessions. The concert hall has 1,000 seats.

**Answer:**

[tex]\mathbf{ P =D(x)= 70 -\dfrac{ x}{20}}[/tex]

**Step-by-step explanation:**

From the information given :

The objective is to find the demand function which is expressed in p, the price in dollars charged for each ticket, as a function of x, and the number of average attendance is:

Suppose the admission price P = D(x) = 30 and number of average attendant = x = 800 people

Then:

ΔP = -1

Δx = 20

[tex]\left \{ \dfrac{\Delta x}{\Delta P }= -20 }}\ \right.[/tex]

According to point line form :

[tex]\dfrac{\Delta x}{\Delta P }= -20[/tex] where the point is (30, 800)

∴

x - 800 = -20 (P - 30)

x - 800 = -20P + 600

collect like terms

x + 20P = 800+ 600

x + 20P = 1400

x = 1400 - 20P

[tex]\mathsf{ P = 70 -\dfrac{ 1}{20}x}[/tex]

Thus, price in dollars for each ticket P = D(x) is:

[tex]\mathbf{ P =D(x)= 70 -\dfrac{ x}{20}}[/tex]

**Answer:**

*12⁴ × 9³ x 4 = ***60,466,176**

*6³ × 8² × 27 =* **373,248**

**Step-by-step explanation:**

You could use the **expanded form to calculate the answer**

12⁴ = 20,736

9³ = 729

4 = 4

**20,736 × 729 × 4 = 60,466,176**

6³ x 8² x 27

6³ = 216

8² = 64

27 = 27

**216 × 64 × 27 = 373,248**

For this question, we need to use PEMDAS to solve the question correctly. PEMDAS stands for "parentheses, exponents, multiplication, division, addition, subtraction". In this question, for the numerator, we see 5 x 3 so that's multiplication. So we multiply those together to get 15. In the denominator, there's an exponent which is 3². We have to find the square of 3 so that we can simplify the denominator as well. That simplifies to 9:

(15+15)/(9+6)

Next, we just have to add the 15+15 in the numerator together and 9+6 in the denominator together:

30/15

Finally, we divide 30/15 to get 2 as our answer

**This is from my understanding, so I may be a bit wrong.**

**1.** First observe the amount of triangles that form, you have two main triangles and one isosceles triangle that forms in the middle by how these are joined together.

**2. **Using this idea we will come up with the equations of each triangle that has been formed.

**3.** We can observe that almost all angles are named with a variable except the one in the middle, being an isosceles we will name the missing variable y.

**4.** Triangle 1(left side) or T1 equals 180 degrees but what angles form this triangle, these would be p+q+y = 180, T2(right side) = r+s+y = 180

**5.** After creating these two triangles we notice that we have not taken into account the triangle in the middle, we are given 1 angle of this isosceles. There is a mathematical property which I don't remember the name, but essentially the angle below is the same as the angle above, this being 120 degrees. This will result in T3 = 2y + 120 = 180

**6. ** Solve for y, which gives us y=30, **simple triangle math you know**

**7. **Finally we fix our equations for p+q+r+s, essentially T1 and T2 will transform into p+q = 180-y and r+s = 180-y, we add them up forming p+q+r+s = 2(180-y)

**8.** Solve the equation p+q+r+s = 360 - 2y which when adding y becomes p+q+r+s = 360-60 = 300

Notes: when doing these exercises it is important to take into account every triangle, the isosceles triangle is very vital for solving it, as it gives us a way for making an equation that is single handedly dependent on y a constant we can find and use. A good approach for these issues would be writing every piece of information as separate sets and then trying to join them using algebra.

FG +31-31 = 49-31

FG = 18

Answer: FG is 18

Step-by-step explanation: FG + GH is FH, GH is 31 and then you substitute 31 in for GH which makes the equation FG+31=49 49-31 is 18 which means FG is 18

Photosynthesis is the process through which plants produce sugar and oxygen. Photosynthesis can also take place in single-celled organisms like phytoplankton and other microorganisms. The process of photosynthesis occurs differently from one organism to the next, but several features remain the same. In short, photosynthesis takes in water and carbon dioxide, uses sunlight as a catalyst, and produces oxygen and sugar. The plants release the oxygen through respiration. They digest or store the sugar. Although the process seems simple, it is the most important event on the planet as far as animal life is concerned. Oxygen is a byproduct of photosynthesis. Animals would not be able to breathe if it was not for this process. Herbivores live off these fruits and vegetables and form the basis of any food chain. Carnivores and omnivores would not be able to find food if it were not for these sugars. Were it not for the simple process of photosynthesis, the Earth would be an uninhabited planet.Animals would not be able to breathe if it was not for this process. How does this sentence help to develop the idea that photosynthesis is essential to animal life? A. It shows that animals depend on this process for oxygen. B. It suggests that photosynthesis occurs in all animals. C. It suggests that photosynthesis takes place in the lungs. D. It shows that animals depend on this process for food.
