The arithmetic mean annual number of people receiving a bachelor's degree in Journalism is about 7,833.

To find the arithmetic mean annual number of people receiving a bachelor's degree in Journalism over the past seven years, we need to calculate the average of the given data set.

The data set representing the number of people receiving bachelor's degrees in Journalism for each of the seven years is:

4,033

5,642

6,407

7,753

8,719

11,154

11,121

To find the mean, we sum up all the values and divide by the total number of years (in this case, seven).

Mean = (4,033 + 5,642 + 6,407 + 7,753 + 8,719 + 11,154 + 11,121) / 7

= 54,829 / 7

≈ 7,832.714

Rounding to the nearest whole number, the arithmetic mean annual number of people receiving a bachelor's degree in Journalism over the past seven years is approximately 7,833.

Therefore, the arithmetic mean annual number of people receiving a bachelor's degree in Journalism is about 7,833.

On the interval [0, 2π), the points which are intersections of r = 5 4 sin(θ) and r = −6 sin(θ) is (3,7π/6) and (3,11π/6) option C and D.

The point of intersection is the junction of two lines or curves.

A point is where two lines from two curves cross.

The point of intersection is a line when two planes collide.

The junction of two lines is referred to as a "point of intersection." These two lines are denoted by the equations a1x+b1y+c1=0 and a2x+b2y+c2=0, respectively. The following diagram displays the location of the junction of the two lines. You may also find the junction of three or more lines.

AB and BC are tangents to P.  The value of x is 3200

AB and BC are tangents to PThe below-given diagram is as follows: AB and BC are two tangents to point P on the circle with center O. To find the value of x, we need to apply a theorem.

Theorem: The tangent at any point of a circle is perpendicular to the radius through the point of contact.Proof: Given a circle with center O. Let the tangent be AB and it touches the circle at point P.Let OP be the radius. Join PA and PB. It is to be proved that OA is perpendicular to AB.

Because OP is the radius of the circle, then OP is perpendicular to AB.To prove the theorem, we only need to show that OA coincides with OP.

Construction: Join OA and extend it to meet AB at Q. To prove that OP coincides with OA, we need to show that OP = OA. Join PB and extend it to meet OA at R. By the Angle Sum Property of a Triangle in ∆OAP,

∠POA + ∠OPA + ∠OAP = 180°

By the Angle Sum Property of a Triangle in ∆OPB,

∠PBO + ∠PBO + ∠OBP = 180°

Because O is the center of the circle, hence OP is equal to OB. Therefore,

∠POA + ∠OPA + ∠OAP = ∠PBO + ∠PBO + ∠OBP∠POA + ∠OPA + 90° = ∠PBO + ∠PBO + 90°

Adding 90° to both sides,

∠POA + ∠OPA + 180° = ∠PBO + ∠PBO + 180°∠POA + ∠OPA = ∠PBO + ∠PBO ……….. (1)

In ∆POR,

∠ROP + ∠RPO + ∠POR = 180°

∠ROP + 90° + ∠POR = 180°

∠ROP + ∠POR = 90° ……….. (2)

In ∆ROB,

∠ORB + ∠RBO + ∠OBM = 180°

∠ORB + 90° + ∠OBP = 180°

∠ORB + ∠OBP = 90° ……….. (3)

From equation (1), we have

∠POA + ∠OPA = ∠PBO + ∠PBO

From equation (2) and (3), we have

∠ROP + ∠POR = ∠ORB + ∠OBP

Substituting, we get

∠ROP + ∠POR = ∠ORB + ∠OBP∠ROP + ∠POR = ∠ROP + ∠RBO∠POR = ∠RBO ……….. (4)

Now, In ∆RPO and ∆RBO

∠RPO = ∠RBO (From equation 4)

∠POR = ∠OBP∆RPO ≅ ∆RBO(OP = OB,

∠RPO = ∠RBO, ∠POR = ∠OBP)RP = RB ……….. (5)

Therefore, OAPB is a parallelogram(OP || AB). From the figure, we can see that 13,200 = x + 9,000. Simplifying, we have:

3200 = x

Therefore, x = 3200Thus, the value of x is 3200.

To show h(t) = |r(t)|², where r(t) is a complex-valued function, we need to first find the magnitude of r(t) and then square it.

Let r(t) = x(t) + i y(t) be a complex-valued function, where x(t) and y(t) are the real and imaginary parts of r(t), respectively. The magnitude of r(t) is given by |r(t)| = √(x(t)² + y(t)²), which is the distance of the point (x(t), y(t)) from the origin in the complex plane.

To find |r(t)|², we simply square the magnitude, i.e., |r(t)|² = (x(t)² + y(t)²).

Therefore, h(t) = |r(t)|² = (x(t)² + y(t)²),

which is the sum of the squares of the real and imaginary parts of r(t).

In the case where r(t) is a real-valued function, i.e., y(t) = 0, then h(t) reduces to h(t) = r(t)².

Probability is a numerical description of how possible an event to happen. Probability of an event can be expressed as

P(A) = n(A) / n(S)

Where

Five people all of different age are sitting around a round table.

Find the probability they are sitting in age order!

Let's name the 5 people 1, 2, 3, 4, 5.

There are two ways in putting them in the age order, ascending or descending.

There are 10 ways that they are sitting around a round table in the age order.

n(Age order) = 10

The total arrangements for 5 people sitting around a round table is

5! = 1 × 2 × 3 × 4 × 5

5! = 120 ways

n(S) = 120

The probability that they are sitting in age order would be

P(Age order) = n(Age order) / n(S)

P(Age order) = 10/120

P(Age order) = 1/12

in a regression with 7 predictors and 62 observations,The degrees of freedom for a t-test for each coefficient would use 55 degrees of freedom (df = 62 - 7 = 55).

The degrees of freedom for a t-test for each coefficient is calculated by subtracting the number of predictors (7) from the number of observations (62) in a regression with 7 predictors and 62 observations,. This leaves us with 55 degrees of freedom (df = 62 - 7 = 55). Degrees of freedom measure the number of observations that are free to vary in estimating a parameter. In other words, they are the number of observations that are used to generate the estimate. In this case, there are 55 observations that can be used to estimate each coefficient.

First prism volume =  L x W x H = 8 x 4 x 5 = 160 cm^3

Second prism = 14 x 8 x 1 = 112 cm^3

   Total =  160 + 112 = 272 cm^3

The volume of the composite solid will be 272 cubic cm.

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as,

V = L x W x H

The shape is the combination of the two rectangular prisms. Then the volume is calculated as,

V = (6 x 4 x 8) + ((14 - 4) x 1 x 8)

Answer:

Like real numbers, the arithmetic operations, such as addition, subtraction, multiplication, and division are applicable to the rational numbers.

Answer:  

Equation translates to 289 + y = 206

it solves to y = -83

====================================================

Explanation:

The "and y more" means we are adding y onto 289 to get the expression 289+y. This is set equal to 206 because of the term "is" in the original statement.

Therefore, "289 and y more is 206" translates fully to the equation 289+y = 206

This is the same as saying y+289 = 206

To isolate y, we undo what is happening to it. We are adding 289 to it, so we must subtract 289 from both sides

y+289 = 206

y+289-289 = 206-289

y = -83

So we are adding -83 to 289 to get 206

Step-by-step explanation:

You want the measure of angle CFE given arcs CD = 46° and DB = 102°, where DE is a diameter of circle A.

The measure of arc CE is the supplement of arc CD, so is ...

  arc CE = 180° -45° = 134°

The measure of angle CFE is the average of the measures of the arcs the chords subtend:

Step-by-step explanation:

False, the response variable, y, and the explanatory variable, x, cannot be interchanged in the least squares regression line equation.

The least squares regression line equation, also known as the regression equation, is a mathematical model that represents the relationship between a response variable, denoted as y, and an explanatory variable, denoted as x. In this equation, y is the variable being predicted or estimated, while x is the variable used to explain the variation in y. The regression equation is typically written as y = mx + b, where m is the slope of the line and b is the y-intercept.

The response variable, y, represents the outcome or dependent variable in a regression analysis, while the explanatory variable, x, represents the predictor or independent variable. These variables have different roles and cannot be interchanged in the regression equation. The slope, m, represents the change in y for a one-unit change in x, and the y-intercept, b, represents the predicted value of y when x is equal to zero.

Interchanging the response variable, y, and the explanatory variable, x, in the regression equation would result in an incorrect representation of the relationship between the variables. It would imply that y is used to explain the variation in x, which is not the intended purpose of the regression model.

Therefore, it is important to correctly identify and use the appropriate response and explanatory variables in the least squares regression line equation to obtain valid and meaningful results.
