The length of the dotted line would be 7.922 ft.

What is the diameter of the circle?

The diameter of a circle is the distance across the circle through its center. It is equal to twice the length of the radius, which is the distance from the center of the circle to any point on the circle.

In mathematical terms, if d represents the diameter of a circle, and r represents its radius, we have the formula:

d = 2r

In the given circle, for finding the inner diameter we have to remove the thickness of the circle from outer diameter, we get

q = 17.708 - 4.893 - 4.893

By solving this, we get

q = 7.922

Hence, the length of the dotted line would be 7.922 ft.

rectangular Persian rug's measurements are 10 ft in length and 1 ft in width.

Let's say that the Persian rug is rectangular, with length "l" and width "w".

The total of a rectangle's four sides is known as the perimeter, and it can be calculated as follows:

Perimeter = 2l + 2w

Given that the distance around it is 22 feet, we can write:

2l + 2w = 22

When we simplify this equation, we obtain:

l + w = 11

A rectangle's area is determined by the product of its length and breadth, which may be written as follows:

l x w = area

Given that the space is 10 square feet, we can write:

l x w = 10

Two equations with two variables are now available:

L+W = 11, and L x W = 10.

To find l and w, we can utilise substitution or elimination. For instance, we can solve for w from the first equation in terms of l:

w = 11 - l

Using this expression as w's replacement in the second equation, we obtain:

l x (11 - l) = 10

The result of expanding and rearrangement is a quadratic equation:

l² - 11l + 10 = 0

Using the quadratic formula or factoring, we can solve this quadratic problem. Factoring results in:

(l - 10)(l - 1) = 0

so either l = 10 or l = 1 is true.

w = 1 if l = 10, otherwise. w equals 10 if l = 1.

As w is always smaller than l, we have

Answer:

3w= 17.98-6.88

3w=11.1

w =3.7

Step-by-step explanation:

After subtracting divide both side by 3

Answer:

w = 3.70

Step-by-step explanation:

Given that,

6.88 + 3w= 17.98 ..........(1)

Now subtracting both sides by 6.88 in equation (1), We have

6.88 + 3w - 6.88 = 17.98 - 6.88

or, 3w + 0 = 11.1

or, 3w = 11.1

Again dividing both sides by 3 in the above equation, We have

[tex]\frac{3w}{3}=\frac{11.1}{3} = 3.70[/tex]

Hence the required answer is w = 3.70

The distance between the point P and the plane through the points Q, R, and S is 60/23.

The distance of a point P(x1, y1, z1) from a plane that passes through the points Q(x2, y2, z2), R(x3, y3, z3), and S(x4, y4, z4) can be found using the following formula:

d = |(A * x1 + B * y1 + C * z1 + D) / sqrt(A^2 + B^2 + C^2)|

Where A, B, and C are the coefficients of the plane's normal vector and D is the constant term in the equation of the plane. The normal vector can be found by taking the cross product of the vectors Q-R and Q-S:

n = (Q-R) x (Q-S)

The coefficients of the normal vector can be found using the following equations:

A = n1

B = n2

C = n3

D = -(A * x2 + B * y2 + C * z2)

Substituting the values of Q, R, and S, we have:

Q-R = (5-0, 0-(-1), 3-7) = (5, 1, -4)

Q-S = (7-5, 5-0, 0-3) = (2, 5, -3)

The cross product of Q-R and Q-S is:

n = (1 * -3 - 5 * -4, -3 * 5 - 2 * -4, -2 * 1 - 5 * 5) = (-23, 29, 17)

So,

A = -23

B = 29

C = 17

D = -(A * x2 + B * y2 + C * z2) = -(-23 * 5 + 29 * 0 + 17 * 3) = -109

Finally, substituting the values of x1, y1, and z1:

d = |(A * x1 + B * y1 + C * z1 + D) / √(A^2 + B^2 + C^2)|

= |(-23 * 3 + 29 * 1 + 17 * 7 + -109) / √(-23^2 + 29^2 + 17^2)|

= |(-69 + 29 + 119 -109) / √(-23^2 + 29^2 + 17^2)|

= |60 / √(-23^2 + 29^2 + 17^2)|

= |60 / √(529)|

= 60 / 23

So the distance between the point P and the plane through the points Q, R, and S is 60/23.

a) The value of z-score is -0.299.

c) The IQR value is measure of spread of data,  IQR = 4.25.

d) There is outliers since observations are not less than 30.375 and greater than 47.375.

The z-score is an example of a standardised score. The standard deviation of a data point's divergence from the mean of the distribution is calculated using a z-score.

Given:

Sample Data = 31.5, 36.0, 37.8, 38.5, 40.1, 42.2, 34.2, 36.2, 38.1, 38.7, 40.6, 42.5, 34.7, 37.3, 38.2, 39.5, 41.4, 43.4, 35.6, 37.6, 38.4, 39.6, 41.7, 49.3

(a) The value of z-score is calculated as follows,

μ = [tex]\sum _{i=1}^n[/tex]/ n = 933.1 /24 = 38.88

σ = 3.61

So, z = X - μ / σ  

 = 37.8 - 38.88/3.61

 = −  0.299

(b) Quartile:

Q₁ = ( n+1/4)th value

= (24+1/4)th

= 6.25th

=  36.2 + 0.25 x ( 37.3 −  36.2 )  

= 36.47

and, M = ( n+1/2)th value

= (24+1/2)th

= (24+1/4)th

=  12.5 t h

= 38.4 + 38.5/2

= 38.45

Q₃ = 3( n+1/4)th

= 3(24+1/4)th

= 18.75 t h  

= 40.6 + 0.75 x ( 41.4  −  40.6 )  

= 41.2

(c) Interquartile​ range

=  Q ₃ −  Q ₁  

= 41.2  −  36.47  

= 4.25

(d) Lower fences =  Q₁− 1.5 ( I Q R )  

                           =  36.75 −  1.5  ( 4.25 )  

                           =   30.375  

Upper fences = Q ₃+1.5

                      =  41 + 1.5( 4.25 )  

                      = 47.375

Hence, there is outliers since observations are not less than 30.375 and greater than 47.375.

so 15 multiplied 3 more times by itself (15 * 15 * 15 * 15) its 15^4.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, occasionally referred to as a "linear equation of two variables."

It is given that the amount of fuel filled up in Jon's semi truck is 240 gallons.

It is also given that for 1 mile the truck uses 0.15 gallons of fuel.

So, for "x" miles, the truck uses 0.15*x gallons of fuel.

So, the remaining fuel in the tank will be 240-0.15x.

Let the remaining fuel be "y".

This can be written as:

[tex]y=240-0.15x\\y=-0.15x+240[/tex].

Therefore the remaining fuel in the tank after Jon drives x miles will be a linear equation [tex]y=-0.15x+240[/tex]
