Calculate the lateral surface area of the cylinder below. Use 3.14 for pi.

Answer:

The correct statements regarding correlation coefficient are:

1. Its absolute value cannot exceed 1.

2. A positive value indicates a strong correlation between the two variables; a negative value indicates a weak correlation between the two variables.

3. If X and Y have positive correlation coefficient, when we run a regression analysis Y=a+bX+e, we will find b positive.

4. If X and Y have positive correlation coefficient, when we run a regression analysis Y=a+bX+e, we will find a positive.

Step-by-step explanation:

Correlation measures the strength of the relationship which exists between X and Y variables.   Regression, on the other hand, helps to establish a cause and effect between a dependent variable and an independent variable.

Answer:

(0, 0) and (3, 0)

Step-by-step explanation:

Zeros of any equation means, value of variable x at y = 0.

Given quadratic equation is,

y = -x(x - 3)

For y = 0,

-x(x - 3) = 0

x = 0

And (x - 3) = 0

x = 3

Therefore, x-intercepts of the given quadratic equation will be,

x = 0, 3

Points showing the x-intercepts will be,

(0, 0) and (3, 0)

Answer:

Step-by-step explanation:

The slope formula is useful for this.

  m = (y2 -y1)/(x2 -x1)

__

First line:

  m = (-9 -(-9))/(9 -(-6)) = 0/15 = 0

The slope of the first line is zero.

__

Second line:

  m = (-5-1)/(4 -4) = -6/0 = undefined

The slope of the second line is undefined.

_____

It is always a good idea to apply a little critical thinking to the given information. Here, you observe that the y-coordinates of the first pair of points are the same. That means this is a horizontal line, with a slope of 0.

Similarly, you observe that the x-coordinates of the second pair of points are the same. That means this is a vertical line, with undefined slope.

Hello there! We're provided with two problems in one, but we can solve each of them by using the slope formula, which is this:

[tex]\stackrel\diamond{\boxed{\boxed{\bold{\frac{y_2-y_1}{x_2-x_1}}}}}[/tex]

In this formula,

Plug in the values:

So the slope is 0.

       <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

The second problem can be solved the same way!

Once again, we'll use the formula

[tex]\stackrel\diamond{\boxed{\boxed{\bold{\frac{y_2-y_1}{x_2-x_1}}}}}[/tex]

only this time, the values are different:

Plug in the values:

So the slope's undefined. I hope this helps, feel free to comment if you have any queries regarding the slope formula! ^^

Answer:

The vehicle can drive 450 miles.

Step-by-step explanation:

You must find how many miles the car goes on one gallon, so since 300÷20= 15, you then know that the car can travel 15 miles per gallon. Therefore, you must do 15 x 30 to get 450 miles.

Answer:

450 miles

Step-by-step explanation:

By 20 gallons,the car travels 300 miles

by 1 gallon, car travels 300÷ 20 miles

By 30 Gallons, car travels: (300÷20 )×30

450miles

Answer:

D

Step-by-step explanation:

For simplify the work we can start to factorise all the possibles expressions:

2x + 8.

8 is multiple of 2, so it can became

2(x+4)

x^2 - 16 this is a difference of two squares, so it can be rewritten as:

(x+4)(x-4)

x^2 + 8x + 16

we have to find two numbers whose sum is 8 and whose product is 16

the two number are 4 and 4

it becames:

(x+4)(x+4)

x+ 4 can‘t be simplified

if we look at the expression, we can find that x-4 appears at the numerator so

x^2 - 16 must be at numerator

but the second factor (x+4) doesn’t appear, so has been simplified. This situation can be possible only in the D option

in fact

(x+4)(x-4)/2(x+4) * (x+4)/(x+4)(x+4)

it became

(x+4)(x-4)/2 * 1/(x+4)(x+4)

(x-4)/2(x+4)

Explain how to rewrite the function shown in order to determine the transformation of the parent function. Then, describe the transformation of the graph compared to  the parent function.

Rewrite the equation by factoring –8 from the radicand and taking the cube root to get –2 in front of the radical symbol.

The graph is reflected over the x-axis.

The graph is also reflected over the y-axis.

The graph is vertically stretched by a factor of 2.

The graph is translated ½ unit to the left.

Answer:

x=1

Step-by-step explanation:

Answer:

x=1

Step-by-step explanation:

x-1/5=x-1/2

2(x-1)=5(x-1)

2x-2=5x-5

-2=5x-5-2x

-2=3x-5

-2+5=3x

3=3x

1=x

Hello your has some missing information attached below is the missing information

answer : 2355.62

Step-by-step explanation:

Calculating the residual for Palm Beach county

Given that total votes = 430772

and The regression equation = 56.115131 + 0.0023197 * Total Votes

The predicted Buchanan = 56.115131 + 0.0023197 * 430772 = 1055.377

while the Actual Votes Buchannan = 3411

Residual for Palm Beach county = Actual votes Buchannan - Predicted

                                                      = 3411 - 1055.377 = 2355.62

Answer:

lateral surface area of cone =

[tex]\pi rl[/tex]

where, l = slant height, and r = radius

then

[tex]l.a = \pi \times 8 \times 17[/tex]

[tex]l.a = 136\pi[/tex]

The lateral area of this cone will be 136 π. Lateral area is found as the product of pi ,radius and slant height.

It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.

lateral area of this cone is found as;

L=πrl

L=π×8×17

L=136π

Hence,the lateral area of this cone will be 136 π.
