If the measurements were taken in centimeters rather than inches, the value of the correlation coefficient would be the same. Correlation coefficient measures the linear relationship between two sets of variables, regardless of the unit measure used.

The correlation coefficient ranges from -1 to +1. A correlation coefficient of 1 indicates a perfect positive correlation between two variables, meaning that as one variable increases, the other variable increases proportionally. A correlation coefficient of -1 indicates a perfect negative correlation, meaning that as one variable increases, the other decreases proportionally. Finally, a correlation coefficient of 0 indicates no linear relationship between the two variables.

In summary, the correlation coefficient is not influenced by the unit measure used, so if the measurements were made in centimeters instead of inches, the correlation coefficient would still be the same.

Answer:

41.8887 cm^2

Step-by-step explanation:

area of a circle
A = pi * r^2
A = pi * (3 + 4)^2
A = pi * 49
A = 153.94

120 / 360 = 1/3
153.94 / 3 = 51.3134

now area of inner circle
A = pi * 3^2
A = pi * 9
A = 28.274
28.274 / 3 = 9.4247

subtract
51.3134 - 9.4247 = 41.8887

Answer:

(C)7b

Step-by-step explanation:

Given the expression:

\(\dfrac{7}{3}ab-\dfrac{7}{6}b\)

Let us factor the expression:

\(=\dfrac{7b}{3}\left(a-\dfrac{1}{2}\right)\)

Since we need the greatest common factor, we can rewrite the expression as:

\(7b\left(\dfrac{1}{3}a-\dfrac{1}{6}\right)\)

Therefore, the greatest common factor is 7b.

The correct option is C.

The value of sin(t/2) is sqrt(2/9), which is the simplified result. the square root of both sides and considering that sin(t) < 0, we get:

sin(t) = -sqrt(1 - (5/9)^2).

Given that cos(t) = 5/9 and sin(t) < 0, we can use the Pythagorean identity sin^2(t) + cos^2(t) = 1 to find the value of sin(t).

Since cos(t) = 5/9, we can square both sides of the equation to get:

cos^2(t) = (5/9)^2.

Using the Pythagorean identity, we have:

sin^2(t) = 1 - cos^2(t) = 1 - (5/9)^2.

Taking the square root of both sides and considering that sin(t) < 0, we get:

sin(t) = -sqrt(1 - (5/9)^2).

Now, we need to find the value of sin(t/2). Using the half-angle identity for sine, sin(t/2) = sqrt((1 - cos(t))/2).

Substituting the values we found earlier:

sin(t/2) = sqrt((1 - 5/9) / 2) = sqrt(4/18) = sqrt(2/9).

Therefore, the value of sin(t/2) is sqrt(2/9), which is the simplified result.

The line is passing through the points (5,-1) and (8,3).

Thus, we form the equation of the line with these two coordinates

and to find the value of k, from(17,k)

as the line also passes through the point (17, k), So, the point (17, k) must satisfy the equation of line.

The general equation of line :

Substitute the coordinates : (5,-1) and (8,3).

The equation of line : y = 4/3(x - 5) - 1

As the point ( 17, k) is also passes through the same line, so they must satisfy the equation of line.

k = 15

Answer : k = 15

The equation y + 1 = (1/4)(x - 4) in point-slope form for the line parallel to y = (1/4)x + 7 and passing through (4, -1).

To find the equation of a line that is parallel to the graph of y = (1/4)x + 7 and passes through the point (4, -1), we can use the point-slope form of a linear equation:

y - y₁ = m(x - x₁)

Where:

m is the slope of the line

(x₁, y₁) are the coordinates of the given point

In this case, since the line is parallel to y = (1/4)x + 7, the slope of the new line will be the same, which is 1/4.

Using the point-slope form with the given point (4, -1), the equation becomes:

y - (-1) = (1/4)(x - 4)

Simplifying further:

y + 1 = (1/4)(x - 4)

This is the equation in point-slope form for the line parallel to y = (1/4)x + 7 and passing through (4, -1).

Answer:

  x = -3

Step-by-step explanation:

You want to know the equation of the axis of symmetry, given that the vertex coordinates of the quadratic are (-3, 4).

The equation of the axis of symmetry is the equation of the vertical line through the vertex. You have correctly located that line at x = -3. (Good Job)

The equation of the axis of symmetry is ...

  x = -3

Additional comment

The equation of a vertical line is of the form x = c, where c is some constant. Here, we need to choose that constant so the line will go through a point that has x-coordinate x = -3. The constant will be -3.

The first team would have 126 members, the second team would have 42 members, the third team would have 84 members, and the fourth team would have 21 members.

Let's assign variables to represent the number of members in each team. Let x be the number of members in the second team. According to the given conditions, the first team would have three times as many members, so the first team would have 3x members. The third team would have twice as many members as the fourth team, so the third team would have 2y members, where y represents the number of members in the fourth team.

To determine the values of x and y, we set up an equation based on the total number of sales reps:

x + 3x + 2y + y = 252

Combining like terms:

4x + 3y = 252

To find a suitable solution, we can try different values of x and y that satisfy the equation. One possible solution is x = 42 and y = 21. Substituting these values back into the equation, we have:

4(42) + 3(21) = 252

168 + 63 = 252

Therefore, the members can be distributed among the teams as follows: the first team would have 3x = 3(42) = 126 members, the second team would have x = 42 members, the third team would have 2y = 2(21) = 84 members, and the fourth team would have y = 21 members.

The discrete probability distribution you are referring to in order to calculate the coefficient of variation. The coefficient of variation is a statistical measure that describes the amount of variation or dispersion relative to the mean of a probability distribution.

Assuming you provide me with the necessary information, I can calculate the coefficient of variation by dividing the standard deviation by the mean, and then multiplying the result by 100 to express it as a percentage. A higher coefficient of variation indicates that the data has more variability relative to the mean, while a lower coefficient of variation indicates that the data has less variability relative to the mean.

The coefficient of variation is most useful when comparing the variability of two or more distributions with different means. If two distributions have similar means, then comparing their standard deviations alone may be more informative. Additionally, the coefficient of variation may not be appropriate for all types of data, such as data that contains negative values or data that has a highly skewed distribution.

The value of the principal investment is $21,597.30. The solution has been obtained by using the concept of compound interest.

What is compound interest?

When interest is calculated, both the principal and the interest that has accumulated over the previous period are used. Compound interest accounts for the principal when calculating the interest for the subsequent month, as opposed to simple interest, which does not. In algebra, the letter C.I. is frequently used to denote compound interest.

We are given that after 16 years in an account with a 6.2% annual interest rate compounded continuously, an investment is worth a total of $58,226.31.

This means that

P(t) = $58,226.31

t = 16 years

r = 6.2%

We know that formula for continuous compounding interest is

\(P(t) = P_{0} e^{rt}\)

So, using this, we get

⇒58,226.31 = Pe^(0.062*16)

⇒58,226.31 = Pe^(0.992)

⇒58,226.31 = P*2.696

⇒P = $21,597.30

Hence, the value of the principal investment is $21,597.30.

Answer:

The y-intercept of g(x) is 4.

Step-by-step explanation:

The linear function has the equation f (x) = m*x + n where, m and n are real numbers called slope (m) and y-intercept (n).

When performing a vertical translation of a function, the graph will move from one point to another determined point in the direction of the "y" axis, that is, up or down. In this way the value of n is modified.

In the function f (x) = - 4x-2, the y-intercept has a value of -2. If this function is translated vertically 6 units up, then the new y-intercept value is -2 + 6 = 4

So, the y-intercept of g(x) is 4.

The y-intercept for the function g(x) is 4.

The y-intercept of a function is a point where the line crosses the y-axis. The linear function can be given as below.

\(f(x) = mx +n\)

Where m is the slope of the line and n is a real number and y-intercept of the line.

The given function is f(x)=-4x—2. The function is vertically translated 6 units up to g(x).

The y-intercept of the function f(x) is -2. Then the y-intercept for the function g(x) can be given as below.

y-intercept g(x) = -2+6

y-intercept g(x) = 4

Hence we can conclude that the y-intercept for the function g(x) is 4.
