The correct option regarding the standard deviation of the residuals is given by:

The point will increase the standard deviation of the residuals because it has a large negative residual.

Considering a scatter plot and a line of best fit, a residual is the difference between the observed value(scatter plot) and the predicted value(line of best fit).

Hence, the circled value has a large negative residual. For the standard deviation, the differences are squared, hence the circled value increasing the standard deviation, and the correct option is:

The point will increase the standard deviation of the residuals because it has a large negative residual.

Step-by-step explanation:

Shaded area = 1 - [tex]\frac{1}{4}[/tex] - [tex]\frac{3}{7}[/tex] (Make them have the same denominator, 28)

                      = [tex]\frac{28}{28}[/tex] - [tex]\frac{7}{28}[/tex] - [tex]\frac{12}{28}[/tex] (Simplify)

                      = [tex]\frac{28}{28}[/tex] - [tex]\frac{19}{28}[/tex] (Evaluate)

Answer:

1. B irrational number

2. A and F

3.A and C

4.A ,C , F and D

Step-by-step explanation:

1. Is the square root of 14 a rational number? No, the square root of 14 is not a rational number. It is an irrational number as it cannot be expressed in the form of p/q.

2.−4 is an integer. We can say it is also a rational number, but it is neither a natural number, whole number, irrational number nor an imaginary number.

3. 3/8 is a rational number and a whole number because its more than 0

4. When a rational number is split, the result is a decimal number, which can be either a terminating or a recurring decimal. All rational numbers can be expressed as a fraction whose denominator is non-zero. Here, the given number, 3 can be expressed in fraction form as 3⁄1. Hence, it is a rational number.

The value of x that will make each of the parallelogram the given type is:

11. x = 6.5

12. x = 3

A parallelogram is any quadrilateral whose opposite sides are parallel and equal to each other.

Examples of a parallelogram include:

11. The diagonals of a square intersect at right angles, therefore:

13x + 5.5 = 90

13x = 90 - 5.5

13x = 84.5

x = 84.5/13

x = 6.5

12. The four sides of a rhombus are equal in length, therefore:

14 - x = 2x + 5

14 - 5 = 2x + x

9 = 3x

9/3 = x

x = 3

The final coordinates of B' and C' after the rotation are B''(6, -3) and C''(6, 3) while the distance between both points is; 6

Distance between B" and C" is;

B"C" = √[(6 - 6)² +(3 + 3)²]

B"C" = 6

We are given coordinates of vertices of Quadrilateral ABCD  as;

A ( 5,0) , B ( 3,6) , C (-3,6) , and D( -4, -5)

Reflection about the x-axis gives; B (3, 6) , C(-3, 6)

Now, the transformation rule for rotating 90 degrees clockwise is;

(x, y) becomes (y, -x)

Thus, coordinates B' and C' are now;

B''(6, -3) and C''(6, 3)

Distance between B" and C" is;

B"C" = √[(6 - 6)² +(3 + 3)²]

B"C" = 6

The missing number in the expression equivalent to 16 - 5 is 15 - 4.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, two expressions ___ - 4 = 16 - 5.

Now, RHS of the expression can be written as,

16 - 1 - 4.

= 15 - 4.

Therefore, LHS of the equation is 15 - 4.

Answer:

27 gallons

Step-by-step explanation:

A rectangular room is a rectangular prism. The floor and ceiling are the bases. The walls are the lateral faces. The lateral are of a rectangular prism is the product of the perimeter of the base and the height of the prism.

lateral area = Ph

lateral area = 2(10 ft + 18 ft) × 8 ft

lateral area = 448 ft²

area of walls = 448 ft²

area of three coats = 3 × 448 ft² = 1,344 ft²

area covered by 1 gallon of paint = 50 ft²

number of gallons of paint needed = 1344 ft² / 50 ft² = 26.88
