To determine which company has higher salaries, you can use the mean, median, or mode as measures of center. Let's calculate each of these measures for the given data:

Company A salaries: 45,000, 55,000, 53,000, 51,000, 49,000, and 42,000.

Mean (Average):

To calculate the mean, sum up all the salaries and divide by the total number of salaries.

Mean of Company A salaries = (45,000 + 55,000 + 53,000 + 51,000 + 49,000 + 42,000) / 6 = 295,000 / 6 = 49,167

Median:

To find the median, you arrange the salaries in ascending order and find the middle value. If there is an even number of values, you take the average of the two middle values.

Arranging the Company A salaries in ascending order: 42,000, 45,000, 49,000, 51,000, 53,000, 55,000

Median of Company A salaries = (49,000 + 51,000) / 2 = 50,000

Mode:

The mode represents the value(s) that appear most frequently in the dataset.

In Company A salaries, all the values occur only once, so there is no mode.

Now let's calculate the same measures for Company B salaries:

Company B salaries: 54,000, 39,000, 51,000, 52,000, 44,000, and 48,000.

Mean of Company B salaries = (54,000 + 39,000 + 51,000 + 52,000 + 44,000 + 48,000) / 6 = 288,000 / 6 = 48,000

Arranging the Company B salaries in ascending order: 39,000, 44,000, 48,000, 51,000, 52,000, 54,000

Median of Company B salaries = (48,000 + 51,000) / 2 = 49,500

Mode of Company B salaries = There are no repeating values, so there is no mode.

To summarize:

- Mean of Company A salaries: $49,167

- Median of Company A salaries: $50,000

- Mode of Company A salaries: No mode

- Mean of Company B salaries: $48,000

- Median of Company B salaries: $49,500

- Mode of Company B salaries: No mode

Based on these measures of center, we can see that the mean and median salaries of Company A are slightly higher than those of Company B. However, since there is no mode in either dataset, we cannot consider the mode as a determining factor in this case.

Answer:

The equation for a parabola that opens down, translated to the right 3, and translated down 2 can be written in the standard form as:

y = a(x - h)^2 + k

where (h,k) represents the vertex of the parabola. Since the parabola opens down, the value of 'a' must be negative. The vertex is translated to the right 3 and down 2, so we have:

h = -3 and k = -2

Substituting these values in the standard form equation, we get:

y = a(x + 3)^2 - 2

This is the equation for a parabola that opens down, translated to the right 3, and translated down 2.

Let's evaluate the probability based on the given information.

The number of ways to choose 6 men from 26 can be calculated as:

C(26, 6) = 26! / (6! * (26-6)!) = 26! / (6! * 20!) = 230,230.

The number of ways to choose 6 women from 29 can be calculated as:

C(29, 6) = 29! / (6! * (29-6)!) = 29! / (6! * 23!) = 177,100.

The total number of possible outcomes is the combination of selecting 6 men and 6 women from the given pool of 26 men and 29 women:

Total outcomes = C(26, 6) * C(29, 6) = 230,230 * 177,100 = 40,795,315,300.

Therefore, the probability of selecting exactly 6 men and 6 women from the given pool is:

Probability = 1 / Total outcomes = 1 / 40,795,315,300 ≈ 2.45 x 10^-11.

Hence, the probability is approximately 2.45 x 10^-11.

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.

We have,

To solve the integral ∫ (log(1 + x²) / (x + 1)²) dx, we can use the method of substitution.

Let's substitute u = x + 1, which implies du = dx. Making this substitution, the integral becomes:

∫ (log(1 + (u-1)²) / u²) du.

Expanding the numerator, we have:

∫ (log(1 + u² - 2u + 1) / u²) du

= ∫ (log(u² - 2u + 2) / u²) du.

Now, let's split the logarithm using the properties of logarithms:

∫ (log(u² - 2u + 2) - log(u²)) / u² du

= ∫ (log(u² - 2u + 2) / u²) du - ∫ (log(u²) / u²) du.

We can simplify the second integral:

∫ (log(u²) / u²) du = ∫ (2 log(u) / u²) du.

Using the power rule for integration, we can integrate both terms:

∫ (log(u² - 2u + 2) / u²) du = log(u² - 2u + 2) / u - 2 ∫ (log(u) / u³) du.

Now, let's focus on the second integral:

∫ (log(u) / u³) du.

This integral does not have a simple closed-form solution in terms of elementary functions.

It can be expressed in terms of a special function called the logarithmic integral, denoted as Li(x).

Therefore,

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.

The probability of 12 women jurors being chosen is approximately 0.000342 or 0.0342%.

To calculate the probability of selecting 12 women jurors out of a pool of 26 men and 29 women, we need to consider the total number of possible combinations and the specific combination of interest.

The total number of ways to choose 12 individuals from a pool of 55 (26 men + 29 women) is given by the combination formula:

C(55, 12) = 55! / (12! * (55-12)!) = 22579284062370.

The number of ways to choose 12 women from a pool of 29 is given by the combination formula:

C(29, 12) = 29! / (12! * (29-12)!) = 7726160.

Therefore, the probability of selecting 12 women jurors is the ratio of the number of ways to choose 12 women to the total number of possible combinations:

P(12 women jurors) = C(29, 12) / C(55, 12) ≈ 7726160 / 22579284062370 ≈ 0.000342.

Answer:

See below for answers and explanations

Step-by-step explanation:

a, b, and c are the coefficients of the quadratic, so a=1, b=6, and c=-12

(h,k) is the vertex of the parabola, so we must convert it to vertex form by completing the square:

[tex]y=x^2+6x-12\\y+21=x^2+6x-12+21\\y+21=x^2+6x+9\\y+21=(x+3)^2\\y=(x+3)^2-21[/tex]

Therefore, the vertex is (3,-21), which means h=-3 and k=-21.

The y-intercept is when x=0, or when the function passes through the x-axis:

[tex]y=x^2+6x-12\\y=0^2+6(0)-12\\y=-12[/tex]

Therefore, the y-intercept is -12 (also written as (0,-12) as an ordered pair).

The x-intercept is when y=0, or when the function passes through the y-axis:

[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-6\pm\sqrt{6^2-4(1)(-12)}}{2(1)}\\\\x=\frac{-6\pm\sqrt{36+48}}{2}\\\\x=\frac{-6\pm\sqrt{94}}{2}[/tex]

Therefore, the x-intercepts are (-6+√94)/2 and (-6-√94)/2.
