Answer:

Step-by-step explanation:

This portion of the graph is completely flat, and has a slope of 0. The slope is the rate of change. Any horizontal line has a slope of 0 (we can use the slope formula to prove this). The term 'constant" means "it does not change".

In contrast, sections A, B, and D are all increasing sections because they go uphill as we move from left to right. The slopes of each line segment are positive.

The increased percent and decreased percent of an item are not equal.

What is Percent formula?

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

Now,

Let the original price of an item = $100

After increased by $10,

Increased percent of an item = 10 * 10/100 = 10%

The new cost of an item = $100 + $10 = $110

After decreased by $10,

Decreased percent of an item = 10 * 10/110 = 9.1%

So, The increased percent and decreased percent of an item are not equal.

Answer:

The correct option is (A). The first equation is for sample​ data; the second equation is for a population.

Step-by-step explanation:

According to the scenario, the following would be represented as a sample and the population

Y with caret = b0 + b1x = sample

and

y = b0 + b1x =  population

It is because if we considered the population than the expected value would be nearest and there is no need to determine the b0 and b1 value again. But in the case of the sample, the reestimation of the values would be determined again and again

Therefore the correct option is A.

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.

Answer:

B. [tex] \frac{60 hours}{1} \times \frac{1 day}{24 hours} [/tex]

Step-by-step explanation:

Converting 60 hours to days:

24 hours = 1 day

60 hours = x day

Cross multiply

[tex] 24 hours \times x = 60 hours \times 1 day [/tex]

Divide both sides by 24 hours

[tex] x = \frac{60 hours \times 1 day}{24 hours} [/tex]

Thus,

[tex] \frac{60 hours \times 1 day}{24 hours} = \frac{60 hours}{1} \times \frac{1 day}{24 hours} [/tex]

The expression that shows how to convert 60 hours to days is:

[tex] \frac{60 hours}{1} \times \frac{1 day}{24 hours} [/tex]

The vertices of the image are R'(x, y) = (- 1, - 7), S'(x, y) = (4, - 7), T'(x, y) = (4, - 5) and V'(x, y) = (- 1, - 3).

In this question we know the locations of the four vertices of the trapezoid RSTV and we need to determine the coordinates of its image by using a reflection formula about an axis parallel to the y-axis, whose formula is described below:

P'(x, y) = P(x, y) - 2 · [P(x, y) - (p, k)]    

Where:

Now we proceed to find the coordinates of the images:

R'(x, y) = (- 1, 1) - 2 · [(- 1, 1) - (- 1, - 3)]

R'(x, y) = (- 1, 1) - 2 · (0, 4)

R'(x, y) = (- 1, 1) + (0, - 8)

R'(x, y) = (- 1, - 7)

S'(x, y) = (4, 1) - 2 · [(4, 1) - (4, - 3)]

S'(x, y) = (4, 1) - 2 · (0, 4)

S'(x, y) = (4, 1) + (0, - 8)

S'(x, y) = (4, - 7)

T'(x, y) = (4, - 1) - 2 · [(4, - 1) - (4, - 3)]

T'(x, y) = (4, - 1) - 2 · (0, 2)

T'(x, y) = (4, - 1) + (0, - 4)

T'(x, y) = (4, - 5)

V'(x, y) = (- 1, - 3) - 2 · [(- 1, - 3) - (- 1, - 3)]

V'(x, y) = (- 1, - 3) - 2 · (0, 0)

V'(x, y) = (- 1, - 3)

The vertices of the image are R'(x, y) = (- 1, - 7), S'(x, y) = (4, - 7), T'(x, y) = (4, - 5) and V'(x, y) = (- 1, - 3).

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 - 5 = 2x + x

9 = 3x

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

Answer:

[tex]\dfrac{2}{3}[/tex]

Step-by-step explanation:

Given that:

The number of observations is:

6, 10, 12

If we are to use a simple  random sampling without replacement, then we will have:

(6,10)  (6,12)  (10,12)

Here;

the sample size n = 2

The population size N = 3

For (6,10) ; The sample mean = [tex]\dfrac{6+10}{2}[/tex]

= [tex]\dfrac{16}{2}[/tex]

= 8

For (6,12) ; The sample mean = [tex]\dfrac{6+12}{2}[/tex]

= [tex]\dfrac{18}{2}[/tex]

= 9

For (10, 12) ; The sample mean = [tex]\dfrac{10+12}{2}[/tex]

= [tex]\dfrac{22}{2}[/tex]

= 11

The probability distribution of sample mean(x) is:

X           8           9          11

P(X=x)    [tex]\dfrac{1}{3}[/tex]          [tex]\dfrac{1}{3}[/tex]           [tex]\dfrac{1}{3}[/tex]

Thus, the probability that the sample mean  is larger than 8 is:

P(X> 8) = P(X = 9) + P(X + 11)

P(X> 8) = [tex]\dfrac{1}{3}+\dfrac{1}{3}[/tex]

P(X > 8) = [tex]\dfrac{1+1}{3}[/tex]

P(X> 8) = [tex]\dfrac{2}{3}[/tex]

The easiest way to get the maximum r value is to draw a line from the origin at angle θ until it hits the semicircle, and a line from there to (2,0)(2,0). Then you can see in the diagram a right-angled triangle (because the angle in a semicircle is a right angle) with hypotenuse 22, and so we get max=2cosrmax=2cos⁡θ.

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]
