The false statement about completely random designs is this:  c.) The additional variables affect different control groups differently.

The false statement about completely random designs is that additional variables affect different control groups differently. It is however true that in completely random esigns, the subjects are randomly assigned to treatments and any number of treatments may be addressed.

Also, the goal of this type of design is to reduce the effects of confounding variables. So, the correct option number that describes the false statement is C.

The value that can take the place of "?" is -6a. The length of line AB is 6a units.

The distance or length of any line on the graph,

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where,

d = distance/length of the line between point 1 and 2,

(x₁ , y₁) = coordinate of point 1,

(x₂ , y₂) = coordinate of point 2,

The length of a line with two points known is written as,

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Given the coordinate of points A and B are (-3a,b) and (-3a,b), respectively. Therefore, the length of the line AB can be written as,

[tex]AB = \sqrt{(-3a-3a)^2+(b-b)^2}\\\\AB = \sqrt{(-6a)^2+(0)^2}\\\\AB = 6a[/tex]

Hence, the length of line AB is 6a units.

Answer:

Mr. Hildebrant planned to spend $95 in the gift shop.

Step-by-step explanation:

We want to find 80% of $? equals $76.

We can write an equation to help us solve for x, the money that Mr. Hildebrant planned to spend in the gift shop.

Divide both sides of the equation by .80.

Mr. Hildebrant planned to spend $95 in the gift shop.

Answer:

Option D: 20km South

Step-by-step explanation:

Lets say A = (0, 0)

A is 30km East of D which makes D = (-30, 0)

D is 10km South of F which makes F = (-30, 10)

F is 10km West of B which makes B = (-20, 10)

A is 10km North of C which makes C = (0, -10)

C is 20km East of E which makes E = (-20, -10)

Find distance from B = (-20, 10) to E = (-20, -10)

     1. Cancel equivalent values:

x of B = (-20) and x of E = (-20)

Remove x from equation.

     2. Solve for answer:

B = 10 and E = (-10)

Find the difference: (-10) - 10 = (-20)

Conclusion:

South translates to negative on a graph making the answer 20km South

You need to add them all.

The expression is 2(n-6), and in these two operations are

multiplication and subtraction with two constants 2, and 6.

Arithmetic is an area of mathematics involving the study of numbers and the different operations that can be performed on them. Addition, subtraction, multiplication, and division are the four basic math operations.

We have:

Twice the difference between a number and six

Let's suppose the number is n, then the expression becomes:

= 2(n-6)

The true statements are:

Thus, the expression is 2(n-6), and in these two operations are

Answer:

P = 17

Step-by-step explanation:

let's separate this into x and y components

x component: 3x

as x increases, so does the x component. e.g. 0 * 3 = 0, 4 * 3 = 12. therefore, we want x as high as possible

y component: y

as y increases, so does the y component. this is because the y component is literally just y.

therefore, given these two, to maximize P, we want x and y to be as high as possible

in 0 ≤ x ≤ 4, the maximum of x is 4

in -1 ≤ y ≤ 5, the maximum of y is 5

plug these in to get

3(4) + 5 = 17 as our answer

Answer:

Step-by-step explanation:

Formula : ( surface area of a cone )_________________________

The total surface area = The curved surface area + area of the base

____________________________________________________

→The curved surface area = π × r × g = π × r × (√(h2 + r2))

 where g is the slant height of the cone and r is the radius of the base

 and h is the height of the cone

 and g = √(h2 + r2)

→Area of the base = π × r²

We get :

The curved surface area = π × r × (√(h2 + r2))

                                         = π × 5.1 × √(14^2+(5.1)^2)

                                         = 238.729625746288                                        

Area of the base = π × r²

                            = π × (5.1)^2

                            = 81.712824919871

Conclusion:

The total surface area = The curved surface area + area of the base

                                     = 238.729625746288 + 81.712824919871

                                     = 320.442450666159
