Based on the information given, the standard deviation for the observation is: 23.802698 or approximately 24.

The standard deviation in statistics is a measure of the degree of variation or dispersion in a set of values. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.

The formula for Standard deviation is given as:

σ[tex]= \sqrt{\frac{1}{N-1} \sum_{i=1}^N (x_i - \overline{x})^2} .[/tex]

Where

σ = population standard deviation

[tex]\bar x[/tex] =  mean

x = each value of the population

n = number of observation

Note that mean ([tex]\bar x[/tex]) = [tex]\( \frac{1}{n} \sum_{i=i}^{n} x_{i} \),[/tex]

[tex]\bar x[/tex] = (5+10+10+10+10+12+15+20+20+25+30+30+40+40+60+60+65+70+70+70)/20

= 33.6

Hence the standard deviation for travel times for these  20 New York workers is:

Standard Deviation = [tex]\sqrt{\frac{\sum(x_{1} - {\bar x})^{2} }{n-1} }[/tex]

= √ [(5-33.6)²+ (10 - 33.6)² + .... + (70 - 33.6)²]/(20-1)]

Standard Deviation = √(10764.8)/(20-1)

SD = √(10764.8/19)
SD = √566.56842
SD = 23.802698

The value of of angle x of the circumscribing circle is x° = 140°

In the above question, the following figure is given, where

The angle inside the circle made by the intersection of two line segments is = 40°

We need to find the angle x made by the angle made by the tangents outside the circle

A line that touches a curve or a circle at one point is said to be tangent.

The point of tangency is the intersection of the tangent line and the curve.

We'll find the value of of angle x using the theorems of the circumscribing   circle.

The sum of opposite angles of a circumscribing quadrilateral is always 180°

Using this property we can write,

40° + x° = 180°

x° = 180° - 40°

x° = 140°

Hence, the value of of angle x using the theorems of the circumscribing   circle is x° = 140°

The vertex form is y= (x+ 6)²+1.

The vertex form of a quadratic equation is y = a (x- h)² + k as opposed to the regular quadratic form, which is an x² + bx + c = y. In both cases, the variables that indicate whether the parabola is facing up (+ a) or down ( a) are y, the y-coordinate, x, and a.

a=1

b=12

c=37

Consider the vertex form of a parabola.

a(x+ d)²+e

Now, d= b/2a

d=12/ 2

d=6

and, e= c-b²-4a

e= 37 - (12)²/4x1

e= 37 - 36

e= 1

Then, the vertex form is

y = a(x+ d)²+e

y= 1(x+ 6)²+1

Answer:

$33,187

Step-by-step explanation:

Our total is 71,482 so let's set our equation to 71482=_________

Now we have $38,295 for one car, and we will subtract it from the total to find the other car, as there are 2 cars.

Equation:

71482-38295=x OR 71482=38295+x

X is the cost of the second car.

After 2.14 hours the trains are exactly 300 miles apart.  

Two trains leave the same station at the same time, one traveling west at a constant speed of 60 miles per hour, the other traveling south at a constant speed of 80 miles per hour.

The time both of them will travel 300 miles can be calculated as follows:

Therefore,

speed = distance / time

distance = speed × time

The train that travel west:

let

t = time of the train that travel west

distance = 60t

The train that travel south:

distance = 80t

Therefore,

total distance = 60t + 80t

300 = 140t

t = 300 / 140

t = 2.14285714286

t = 2.14 hours

Let x represent the rental cost for each movie.

Let y represent the rental cost for each video game.

We were told that One month Tony rented 5 movies and 3 video games for a total of 532. This means that

5x + 3y = 32

Also, the month, he rented 2 movies and 12 video games for a total of $83. This means that

2x + 12y = 83

Dividing through by 2, we have

x + 6y = 41.5

x = 41.5 - 6y

Substituting x = 41.5 - 6y into 5x + 3y = 532, we have

5(41.5 - 6y) + 3y = 32

207.5 - 30y + 3y = 32

- 30y + 3y = 32 - 207.5

- 27y = - 175.5

y = - 175.5/- 27

y = 6.5

x = 41.5 - 6(6.5) = 41.5 - 39

x = 2.5

Rental cost for each movie = $2.5

Rental cost for each video game = $6.5

Answer:

For A and B, we have (10, 6)

For C and D, we have (12, 8)

For E and F, we have (12, 8)

Explanation:

To determine the missing numbers along each side of the triangle, we have to

*Add the two numbers at the vertex

*Subtract it from 32

*Divide it by 2

*Add 2 to it to have the 1st number

*Subtract 2 from it to have the 2nd number

So to find the pair of numbers that can be used for A and B, we'll have;

Therefore the missing numbers for A and B are 10 and 6.

So to find the pair of numbers that can be used for C and D, we'll have;

Therefore the missing numbers for C and D are 12 and 8.

So to find the pair of numbers that can be used for E and F, we'll have;

So to avoid repetition of any of the numbers between 4 and 12, we have to add and subtract 1 instead of 2.

If we express this as an interval, we get [9.52, 22.22].

Here is the inequality which is Kali's earning potential

200 ≤ 15.75x + 50 ≤ 400

To solve the inequality, we must isolate the variable in the center; if we remove 50 from each of the three sides, we get:

The parabola y = - 0.5x² + 2 opens downwards and the vertex is at (0,2) .

A parabola is a mirror-symmetric planar curve with a rough U-shape. It can be defined by many seemingly unrelated mathematical descriptions that all relate to the same curves.

One way to interpret a parabola is with a line and a point (the focus) (the directrix). The directrix is less significant. The parabola lies between the directrix or the focus and the endpoints in this plane that are uniformly spaced apart.

a) y=-0.5x² + 2 vertex is at (0,2)

c) y = -0.1x² - 6 vertex at (0,6)

d)y=x²+4 vertex at (0,-4)

e) y=-3x²-5 vertex at (0,5)

g)y=8x²+4 vertex at (0,-4)

h) y=-0.7x²-3 vertex at (0,3)

Answer

The equation in point-slope form is

y - 1 = (-10/3) (x + 2)

We can then simplify this by multiplying through by 3 to obtain

3y - 3 = (-10) (x + 2)

3y - 3 = 10x - 20

3y = 10x - 20 + 3

3y = 10x - 17

Explanation

The general form of the equation in point-slope form is

y - y₁ = m (x - x₁)

where

y = y-coordinate of a point on the line.

y₁ = This refers to the y-coordinate of a given point on the line

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

x₁ = x-coordinate of the given point on the line

We can calculate the slope of the line and then use any of the two points given to serve as the point (x₁, y₁) in the equation

For a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as

For this question,

(x₁, y₁) and (x₂, y₂) are (-5, 11) and (-2, 1)

x₁ = -5

y₁ = 11

x₂ = -2

y₂ = 1

Slope = m = (-10/3)

Using the point (-2, 1) as (x₁, y₁), we can write the equation of the line

y - y₁ = m (x - x₁)

y - 1 = (-10/3) (x - (-2))

y - 1 = (-10/3) (x + 2)

We can then simplify this by multiplying through by 3 to obtain

3y - 3 = (-10) (x + 2)

3y - 3 = 10x - 20

3y = 10x - 20 + 3

3y = 10x - 17

Now,

We convert the equation in standard form as;

Since, The equation in slope - intercept form as;

⇒ y - 3 = 1/5 (x + 6)

Change into standard form as;

⇒ y - 3 = 1/5 (x + 6)

Multiply by 5 both side, we get;
