Answer:

[tex]Visitors = 130000[/tex]

Step-by-step explanation:

Given

[tex]Visitors = 127034[/tex]

Required

Approximate to the nearest ten thousand

First, identify the digit at the ten thousand position

From the given numbers of visitors, the digit is 2.

So, the next digit (which is 7) will be approximated and added to 2.

7 > 5. So, 1 will be added to 2.

The number of visitors becomes:

[tex]Visitors = 130000[/tex]

Answer:

Step-by-step explanation:

The person I sent it to couldn't see it either. I'm going to take a chance and say the Chord (AB) and the Tangent line form a 50 degree angle. If this is incorrect, I won't know, from the diagram, what else to try.

If I'm right then <OAB = 40 degrees because 90 - 50 = 40 because <AOC is a right angle (property of radii and tangents).

<ABO also = 40 (the triangle is isosceles by two legs being radii).

That means that BOA = 180 - 40 - 40 = 100

two over four is the probability that you will land on seven or eight

Answer:

P( landing an an 8 then on  a 7 ) = 1/ 16

Its is the branch of mathematics concerning numerical description of how likely an event is to occur .

P( landing an an 8 then on  a 7 ) = P ( landing on an 8) * P ( landing on a 7 )

P(Landing on an 8) = 1/4

P(Landing on an 7) = 1/4

P = 1/4 * 1/4

P= 1 / 16

y' = a*b * x^(b-1)

Solution

3x^3 = 3*3x^(3-1)

3x^3 = 9x^2

-2x^-4  = -2*-4 x ^(-4 - 1)

-2x^-4 = 8 x ^-5

Answer:

5 9/14

Step-by-step explanation:

Let's add the whole numbers first to make the process simpler, 4+1=5. So 5 1/7 + 1/2 can be converted to 5 2/14 + 7/14, with a common denominator of 14. Add the numerators together, and you get 5 9/14.

Answer:

[tex]Mean = 48.6364[/tex]

[tex]s^2 = 331.8545[/tex] -- Sample Variance

[tex]s = 18.2169[/tex] --- Sample Standard Deviation

Step-by-step explanation:

Given

[tex]n = 11[/tex]

[tex]Data: 24, 41 ,25 ,68 ,53 ,83 ,43 ,63 ,56 ,34 ,45[/tex]

Solving (a): The sample mean

[tex]Mean = \frac{\sum x}{n}[/tex]

So:

[tex]Mean = \frac{24 +41 +25 +68 +53 +83 +43 +63 +56 +34+ 45}{11}[/tex]

[tex]Mean = \frac{535}{11}[/tex]

[tex]Mean = 48.6364[/tex]

Solving (b): Sample variance (s^2)

This is calculated as:

[tex]s^2 = \frac{\sum (x - \bar x_i)^2}{n - 1}[/tex]

Where:

[tex]\bar x = 48.6364[/tex]

So:

[tex]s^2 = \frac{(24 -48.6364)^2 +(41 -48.6364)^2 +......................+( 45 -48.6364)^2}{11-1}[/tex]

[tex]s^2 = \frac{3318.54545456}{10}[/tex]

[tex]s^2 = 331.8545[/tex]

Solving (c): Sample Standard Deviation (s)

This is calculated as:

[tex]s = \sqrt {s^2[/tex]

[tex]s = \sqrt{331.8545[/tex]

[tex]s = 18.2169[/tex]

Answer:

6/12 is equal to 3/6 ( 6 twelfths is equal to 3 sixths )

Step-by-step explanation:  

multiply both sides of 3/6 by 2 to get the same denominator, doing that will get you 6/12

Answer:

6 copies

Step-by-step explanation:

Step 1:  Convert 1 twelfth to an expression

1 twelfth is the same thing as 1/12

Step 2:  Convert 3 sixths to an expression

3 sixths is the same thing as 3/6

Step 3:  Get common denominators

The lowest common denominator between 1/12 and 3/6 is 12

[tex]\frac{1}{12}[/tex] → [tex]\frac{(1 * 1)}{(12 * 1)}[/tex] → [tex]\frac{1}{12}[/tex]

[tex]\frac{3}{6}[/tex] → [tex]\frac{(3 * 2)}{(6*2)}[/tex] → [tex]\frac{6}{12}[/tex]

Step 4:  Find the amount of 1/12 there are in 6/12

In order to find out the copies, we need to add 1/12 x amount of times to get 6/12.  We find that x is going to be 6.  Therefore, there 6 copies.

[tex]\frac{1}{12}+\frac{1}{12}+\frac{1}{12}+\frac{1}{12}+\frac{1}{12}+\frac{1}{12} = \frac{6}{12}[/tex]

Answer:  6 copies

Answer:

1,769

Step-by-step explanation:

The computation of the sum is shown below:

Future value = Present value × (1 + rate of interest)^number of years

2,590 = Present value × (1 + 0.10)^4

2,590 = Present value × 1.10^4

So, the present value is

= 2,590 ÷ 1.10^4

= 2,590 ÷ 1.4641

= 1,769

Answer:

A. Cos θ = 16/42

Step-by-step explanation:

The angle the ladder makes with the floor = θ

Hypotenuse = length of the ladder = 42 m

Adjacent = Distance from the bottom of the ladder to the wall = 16 m

Therefore to find θ, we would apply the trigonometric function, CAH:

Cos θ = adj/hyp

Which is:

Cos θ = 16/42

Statistic

Step-by-step explanation:

A statistic is a sample of the whole mean like

E.x( how many pink doughnuts are in the dozen pack of doughnuts.

A parameter represent the whole mean

E.x( how many donuts were made at 7:00)

Since they are sampling 25 cars, it is a statistic.
