Answer:

Both variables Can tell you the degree to which a linear relationship exists between two variables.

Step-by-step explanation:

Correlation and regression are two statistical concepts that are closely related and complement each other. They are powerful tools used in modern-day machine learning and artificial intelligence.

Correlation evaluates the linear relationship between two variables, using regression as a tool to assess the degree at which a dependant variable changes ( either increasing or decreasing ) based on the value of an independent variable.

The correlation coefficient is the degree of the linear relationship between two variables, ranging from zero ( for non-linear) to one ( for highly linear).

Answer:

53 m^2

Step-by-step explanation:

53 m^2 is the area of the figure given!

So as given in the question that the sides meet at right angles.

we take the bottom of the upper rectangle as 5m, then the upper side of the lower rectangle will be 3+5+3= 11.

Now, by using the formula of the area of a rectangle that is Area = Height x width, we areas of the two rectangles. Then add both the areas.

Finally we get the area of the given figure!

Hope it helps you!

Answer:

A = 53 m²

Step-by-step explanation:

A = A1 + A2

= 4m×5m + 3m×(3m + 5m + 3m)

= 20m² + 3m×11m

= 20m² + 33m²

= 53 m²

Answer:

354,500 square m

Step-by-step explanation:

Remaining area = Area of park - Area used for soccer and baseball field

A circle is a curve sketched out by a point moving in a plane. The length of the arc with a central angle of 100° and a radius of 2 inches is 3.49 inches.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

Given that the radius of the circle is 2 inches, while the angle made by the arc at the centre of the circle is 100°. Therefore, the length of the arc can be written as,

Length of the arc = 2 × π × R × (θ/360°)

                              = 2 × π × 2 inches × (100°/360°)

                              = 10π / 9  inches

                              = 3.49 inches

Hence, the length of the arc with a central angle of 100° and a radius of 2 inches is 3.49 inches.

Answer: C. "How do you like this great new TV show?"

The term "great" put in there skews the question to make people think the show is great, when it may not be. So people may have a tendency to say they really like the show when they may not.

Or perhaps they may like the show (somewhat) but the fact that they can sense the bias built into the question makes them decide to say opposite and say they don't like the show. Maybe this sort of scenario would have them rebel in a way.

Either way, the use of "great" is likely to alter the opinion of people answering the question.

Answer:

12 [tex]units^{2}[/tex]

Step-by-step explanation:

square: 2 x 2 = 4 units sq

small triangle: 2 x 2 = 4, 4 / 2 = 2 units sq

big triangle: 2 x 6 = 12, 12 / 2 = 6 units sq

4 + 2 + 6 = 12 units sq

Answer:

12 units²

Step-by-step explanation:

we need to notice that the shape has two right triangles and a rectangle

the area of right triangles is b*h/2 and of the rectangle side*length

area of first triangle

Base=2

Height=2

[tex]A=\frac{2*2}{2} =2[/tex]

Area of the square

Side=2

Length=2

[tex]A_2=2*2=4[/tex]

Area of the second triangle

Base=2

Height=6

[tex]A_3=\frac{2*6}{2} =6[/tex]

so we need to add all three areas

[tex]A_T=A_1+A_2+A_3\\\\A_T=2+4+6=12\\\\A_T=12[/tex]

So the area is 12 units²

Answer:

Wyatt played 3 games and went on 6 Rides

Step-by-step explanation:

Let games be represented as x

Let ride be represented as y

Each game cost $1.25

Each ride cost $2.75

Total money spent by Wyatt= $20.25

x1.25 + y2.75 = 20.25 ..... Equation 1

the number of rides he went on is twice the number of games he played

Y= 2x ... Equation 2

Substituting the value of y into equation 1

x1.25 + y2.75 = 20.25

x1.25 + 2(x)2.75 = 20.25

x1.25 + x5.5 = 20.25

x6.75= 20.25

x= 20.25/6.75

X= 3

Y= 2x

Y= 2(3)

Y= 6

Answer: y > (5/2)*x - 3

Step-by-step explanation:

Ok, the thins we should notice.

The line is shaded, so the values of the line are not solutions of the inequality, then we should use < or >.

The shaded part is above the line, so we have:

y > a*x + b.

A linear relationship can be written as:

f(x) = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

Now, we know that our line passes through the points (0, -3) and (2, 2)

Then the slope is:

a = (2 -(-3))/(2 - 0) = 5/2.

f(x) = (5/2)*x + b.

To find the value of b, we can replace the values of one of the points in the equation, let's use the point (0, -3)

f(0) = -3 = (5/2)*0 + b

-3 = b

Then the line is:

f(x) = (5/2)*x - 3

Then the inequality is:

y > (5/2)*x - 3

[tex]\sin O = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex]

[tex]\sec O = \frac{1}{\cos O} = \frac{\sqrt{x^{2}+y^{2}}}{x}[/tex]

[tex]\tan O = \frac{\sin O}{\cos O} = \frac{y}{x}[/tex]

Given that [tex]x = -3[/tex] and [tex]y = 7[/tex], the exact values of sine, secant and tangent are:

Answer:  14) 44°    15) 6.5

Step-by-step explanation:

Law of Cosines: a² = b² + c² - 2bc · cos A

Note: The letters can be swapped

14) Given: a = 7,  b = 6,  c = 10, A = ???

7² = 6² + 10² - 2(6)(10) · cos A

49 = 36 + 100 - 120 cos A

49 = 136 - 120 cos A

-87 =  - 120 cos A

0.725 = cos A

43.5° = A

15) Given: A = 21°,  b = 18,  c = 16

a² = 18² + 16² - 2(18)(16) · cos 21°

   = 324 + 256 - 576 cos 21°

   = 580 - 576 cos 21°

   = 42.26

[tex]a=\sqrt{42.26}[/tex]

   = 6.5

Answer:

Step-by-step explanation:

a) Revenue function us derives by taking the product of the number of yachts and the demand function p given. Mathematically,

R(x) = xp(x)

Given p(x) = 700 − 0.01x ln(x)

R(x) = x{700 − 0.01x ln(x)}

R(x) = 700x - x(0.01x ln(x))

R(x) = 700x - 0.01x²lnx

Hence the revenue function R(x) is expressed as R(x) = 700x - 0.01x²lnx

Marginal revenue function is derived by finding the derivative of the revenue function R(x). On differentiating;

d{R(x)}/dx = 700 - 0.01{x²(1/x)+2xlnx} (note that product rule was used to differentiate the function in parenthesis).

d{R(x)}/dx = 700 - 0.01{x+2xlnx}

Open the parenthesis

d{R(x)}/dx = 700 - 0.01x-0.02xlnx

Hence the marginal revenue function R'(x) is expressed as 700 - 0.01x-0.02xlnx.

b) In order to estimate the revenue to be realized from the sale of the 375th 34 ft Sundancer yacht, we will simply substitute the variable x = 375 into the revenue function R(x)

Given R(x) = 700x - 0.01x²lnx

R(375) = 700(375) - 0.01(375)²ln(375)

R(375) = 262500-1406.25ln(375)

R(375) = 262500-8334.74

R(375) = 254,165.26

Hence the revenue realized from the sale is approximately $254,165

For the Marginal revenue Function,

R'(x) = 700−0.01x−0.02xln(x)

R'(375) = 700−0.01(375)−0.02(375)ln(375)

R'(375) = 700−3.75−0.02(375)ln(375)

R'(375) = 700-3.75-44.45

R'(375) = 651.8

The marginal revenue is approximately $652

Answer:

D

Step-by-step explanation:

We know that we are adding the two expressions because the question says "sum" which means that we need to add. Let's combine like terms. We know that x + 2x = 3x and 5 + 3 = 8 so the answer is 3x + 8.

Answer:

D. 3x+8

Step-by-step explanation:

We want to find the sum of (x+5) and (2x+3). Sum means addition, so we must add the 2 expressions.

(x+5)+(2x+3)

Now, we must simplify by combining like terms.

First, combine the terms with variables.

(x+2x) + (5+3)

3x + (5+3)

Next, add the constants, or terms without variables.

3x+ 8

The sum of (x+5) and (2x+3) is 3x+8. This makes choice D the correct answer.
