Which of the following gases in the atmosphere is not considered a main contributor to the greenhouse effect?.

Answers

Answer: Oxygen (I don’t see the options)

Explanation: A greenhouse gas is a gas that produces heat as it builds up in the atmosphere. It also becomes trapped in the atmosphere, so it cannot escape the inner layers of Earth's atmosphere. As a result, these gases cause pollution because they dirty up the atmosphere.

Carbon dioxide is a main greenhouse gas, found in car exhaust pipes.
Methane and nitrous oxide is another type of greenhouse gas.

*Oxygen is the only clean gas out there because we need it to survive. Therefore, the only gas that is not a greenhouse gas*

Which of the following will be the ratio of the perimeter of the blue triangle to the red triangle.

Answers

The ratio (red to blue) of the perimeters of the similar triangles is 12:7

Assuming that the similar triangles are equilateral triangles, then all their sides will be equal.

Perimeter of a triangle = s1 + s2 + s3

For the red triangle;

Perimeter of the red triangle = 12 + 12 + 12

Perimeter of the red triangle = 36

For the blue triangle:

Perimeter of the blue triangle = 7 + 7 + 7

Perimeter of the blue triangle = 21

Taking the ratio of their perimeters;

Ratio of red to blue = 36:21 = 12:7

Hence the ratio (red to blue) of the perimeters of the similar triangles is 12:7

Using the appropriate sample size formula, the minimum number of samples required is 267

Using the relation :

N = [(Z² × pq) / e²] e = Error Margin = 0.06² = 0.0036p = 0.5 q = 1 - 0.5 = 0.5 Zcritical at 95% = 1.96

Substituting the values into the equation :

N = [(1.96² × (0.5 × 0.5)) / 0.0036]

N = (0.9604 / 0.0036)

N = 266.777

Determine the minimum mass of hydrogen gas required to produce 226 kj of heat.

Answers

By definition, the minimum mass of hydrogen gas required to produce 226 kJ of heat is 1.8697 grams.

The reaction is as follows:

2 H₂(g) + O₂(g) → 2 H₂O(g)     ΔH = - 483.5 kJ

In this reaction, you can see that 2 moles of H₂ produces 483.5 kJ of heat. But you want to release 226 kJ of heat.

So you can apply the following rule of three: if 483.5 kJ is released by 2 moles of H₂, 226 kJ of heat is released by when moles of H₂?

[tex]amount of moles of H_{2} =\frac{226 kJx2 moles }{483.5 kJ}[/tex]

amount of moles of H₂= 0.93485 moles

Molar mass is the amount of mass that a substance contains in one mole. In this case, the molar mass of H₂ is 2 [tex]\frac{g}{mole}[/tex].

So, the mass containing 0.93485 moles is calculated as:

0.93485 moles× 2 [tex]\frac{g}{mole}[/tex]= 1.8697 grams

Finally, the minimum mass of hydrogen gas required to produce 226 kJ of heat is 1.8697 grams.

The distribution of number of hours worked by volunteers last year at a large hospital is approximately normal with mean 80 and standard deviation 7. Volunteers in the top 20 percent of hours worked will receive a certificate of merit. If a volunteer from last year is selected at random, which of the following is closest to the probability that the volunteer selected will receive a certificate of merit given that the number of hours the volunteer worked is less than 90 ?.

Answers

Explanation:

Using the normal distribution, it is found that the probability that the volunteer selected will receive a certificate of merit given that the  number of hours the volunteer worked is less than 90 is closest to:

B 0.123

In a normal distribution with mean \muμ and standard deviation \sigmaσ , the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}Z=σX−μ

It measures how many standard deviations the measure is from the mean.  

After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

The mean is of 80, hence \mu = 80μ=80 .

The standard deviation is of 7, hence \sigma = 7σ=7 .

The minimum value is the 80th percentile, which means that it is X_mXm when Z has a p-value of 0.8.

The probability that the volunteer selected will receive a certificate of merit given that the number of hours the volunteer worked is less than 90 is P(X_m < X < 90)P(Xm<X<90) , which is the p-value of Z when X = 90 subtracted by the p-value of Z when X = X_mX=Xm , hence the p-value of Z when X = 90 subtracted by 0.8.

Z = \frac{X - \mu}{\sigma}Z=σX−μ

Z = \frac{90 - 80}{7}Z=790−80

Z = 1.43Z=1.43

Z = 1.43Z=1.43 has a p-value of 0.9236.

0.9236 - 0.8 = 0.1236, hence closest to 0.123, option B.

Using the normal distribution, it is found that the probability that the volunteer selected will receive a certificate of merit given that the  number of hours the volunteer worked is less than 90 is closest to:

Letter B

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}\\Z=\sigma X - \mu[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X. In this problem:

The mean is of 80, hence [tex]\mu = 80[/tex]. The standard deviation is of 7, hence [tex]\sigma = 7[/tex]. The minimum value is the 80th percentile, which means that it is [tex]X_m[/tex] when Z has a p-value of 0.8.

The probability that the volunteer selected will receive a certificate of merit given that the number of hours the volunteer worked is less than 90, which is the p-value of Z when X = 90 subtracted by the p-value of Z when X = X_mX=Xm , hence the p-value of Z when X = 90 subtracted by 0.8.

[tex]Z = \frac{X - \mu}{\sigma}\\Z=\sigma X - \mu\\Z = \frac{90 - 80}{7}\\Z=790 - 80\\Z = 1.43Z=1.43[/tex]

Has a p-value of 0.9236.

[tex]0.9236 - 0.8 = 0.1236[/tex]

Hence closest to 0.123.

Ryan invests a sum of money in a savings account with a fixed annual interest rate of 4. 31.

Answers

The amount of his initial investment is $8361

The complete question says:

Ryan invests a sum of money in a savings account with a fixed annual interest rate of 4.31% compounded 12 times per year. After 10 years, the balance reaches $12,855.94. What was the amount of the initial investment?

The initial investment is the amount required to start a particular project,  and the amount of the initial investment can be calculated by using the compound interest formula:

[tex]\mathbf{A = P(1 + \dfrac{r}{n})^{nt}}[/tex]

where;

A = amountP = Principalr = interest rate n = number of months

[tex]\mathbf{12855.94 = P(1 + \dfrac{0.0431}{12})^{12 \times 10}}[/tex]

[tex]\mathbf{12855.94 = P(1 +0.003591666667)^{120}}[/tex]

[tex]\mathbf{12855.94 = P(1.53760)}[/tex]

[tex]\mathbf{P= \dfrac{12855.94}{(1.53760)} }[/tex]

P = $8361.043

P ≅ $8361

Therefore, we can conclude that the amount of the initial investment is $8361
