The composition between the functions f(x) = x and g(x) = 2 is equal to (f ° g) (x) = 2. (Correct choice: B)

The composition is a binary operator between two functions, in which the input of the first function is substituted by the second function. This operation is defined by the following expression:

(f ° g) (x) = f[g(x)]  

If we know that f(x) = x and g(x) = 2, then the composition between the two functions is:

(f ° g) (x) = 2

Then, the composition between the functions f(x) = x and g(x) = 2 is equal to (f ° g) (x) = 2. (Correct choice: B)

Segundo o Instituto Nacional de Pesquisas Espaciais (Inpe), de janeiro a setembro de 2019, foram registrados 4.660 focos de incêndio, em 2020 foram registrados 14.489 focos. Qual é a porcentagem de aumento de focos de incêndio em 2020 em comparação com os focos registrados em 2019?

A fórmula de aumento percentual é fornecida como

Aumentar / tamanho inicial × 100

Aumento = 14489 focos de incêndio - 4660 focos de incêndio

= 9829 focos de incêndio

Aumento percentual = 9829/4660 × 100

= 210.92274678 %

≈ 211%

Answer: birr 1780.

Solution:

The cost price of the T.V. set = birr 2000

The loss percentage = 5 1/2%

The formula of the selling price is: Selling Price = (100 - Loss%)/100 × Cost Price

Now,

By using the above formula and by substituting the given values of C.P. and Loss%, we get

Selling Price = (100 - 11)/100 × 2000

Selling Price = 89/100 × 2000

Selling Price = 89 × 20

Selling Price = 1780

Thus, the selling price of the T.V. set was → birr Given:

A trader bought a TV set for birr 2000 and sold it at a loss of 11%

To find:

What was the selling price?

Solution:

The cost price of the T.V. set = birr 2000

The loss percentage = 11%

We know the formula of the selling price is:

Now,

By using the above formula and by substituting the given values of C.P. and Loss%, we get

Thus, the selling price of the T.V. set was → birr 1780.

The variance semifinal round data, s² ≈ 0.10411

The variance of the final round data, s² ≈ 0.26

Semifinal Round

∑(t × f(t)) = 426.5, ∑f(t) = 8

Average = mean = ∑ (t × f(t))/∑f(t)

Therefore;

In semifinal round average time = [tex]\frac{426.5}{8}[/tex]=53.3125

∑(t² × f(t)) = 22,738.51, ∑f(t) = 8  

sample variance = (∑x²·f(t) - ((∑×·f(t))²)/∑f(t))/ ∑f(t) -1

s²=0.10411

Answer:

C.None of the above

Step-by-step explanation:

Let's consider the first answer choice:

The times in the semifinals were faster on average than the times in the finals.

We don't have to calculate the mean values of each distribution because we can see visually that the center of the final round distribution is lower than the center of the semifinal round distribution.

Since lower times are faster, we can't say that the times in the semifinals were faster on average than the times in the finals.

Now, let's consider the second answer choice:

The times in the finals vary noticeably less than the times in the semifinals.

We can see visually that the final round distribution is more spread out than the semifinal round distribution. We could calculate MAD or IQR from these displays, but we can see that the range of the final round distribution is larger.

So we can't conclude that the times in the finals vary noticeably less than the times in the semifinals.

Answer:

A. The parent function is the function with a graph that is different than all the other functions in the family.

Step-by-step explanation:

A parent function is simply a function that represents the simplest form of a family of functions.

Now, a family of functions is defined as a group of functions that share the same highest degree and therefore the same shape for their graphs.

Looking at the options, the only one that doesn't correspond to the definition of parent function with respect to family of functions is option A because it suggests that the parent function is different from the family functions. Thus, option A doesn't describe a parent function.

The mean and (sample) standard deviation σ = 0.2098.

The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.

The mean is the product of the dataset's total and the sample size. Mathematically.

[tex]\bar{x}=\frac{\sum X_i}{N}[/tex]

The individual periods are Xi.

The sample size is N.

[tex]\sum X i[/tex] = 1.06 + 1.31 + 1.28 + 0.99,+  1.48 + 1.37+  0.98 + 1.31 + 1.59 + 1.55

[tex]\sum X i[/tex] = 12.92

N = 10

While substituting the value we get:

x = 12.96/10

x = 1.292

The samples' average is 1.292.

The standard deviation:

[tex]\sigma=\sqrt{\frac{\sum(x-\bar{x})^2}{N}}[/tex]

[tex]\sum(x-\bar{x})^2[/tex] = (1.48-1.292)^2+(1.37-1.292)^2+(0.98-1.292)^2+(1.31-1.292)^2+(1.59-1.292)^2+(1.55-1.292)^2.

[tex]\sum(x-\bar{x})^2[/tex] = 0.43996

Putting into the formula we get:

[tex]\sigma=\sqrt{\frac{0.43996}{10}}[/tex]

σ = √(0.043996)

σ = 0.2098

The mean and (sample) standard deviation σ = 0.2098.

The difference in the total costs of the 12 pairs of shoes between the two sites is $46.77,

Total cost is the sum up cost for all the individual process. we can find it by adding the cost for each steps.

In the given ques,

Super Sports is offering a 20% discount.

and shoes were originally priced at $72.50 and that a 6.5% sales tax will be applied.

On Double Dribbles, the same shoes were on for $54.75, and a 9% is added and has an extra $5.99 for shipping.

i.e. we  have to find the difference in the total costs..

Now we have to multiply 12 by 72.50. The answer to that is 870. Next, we need to multiply 8 by 870 and divide it by 10. The answer to that is 696. Then, we need to add the price and the tax. The price will be 100%, and the tax will be 6.5%. 100 + 6.5 = 106.5. After that, we need to 106.5 by 100. The answer it that is 1.065. Now do  times 1.065 by 696. And the answer to that is $741.24.

Do the same for other store.  The answer to it is 788.01.

Thus, making Super Sports a better deal.

As, we need to find the difference. So, 788.01 - 741.24 = $46.77.

Answer:

value of a in terms of b and c is: [tex]\mathbf{a=bc}[/tex]

Option D is correct.

Step-by-step explanation:

We are given:

[tex]a=b^2c^2d \:and\: d=\frac{1}{a}[/tex]

We need to find a in terms of b and c

We have: [tex]a=b^2c^2d[/tex]
