Answer:5

Step-by-step explanation:

Given

There are total of 150 ticket

If the probability to win a raffle is [tex]\frac{1}{30}[/tex]

[tex]Probability =\frac{\text{Favorable outvome }}{\text{Total outcome}}[/tex]

[tex]\frac{1}{30}=\frac{\text{no of tickets bought}}{\text{Total no of tickets}}[/tex]

[tex]\frac{1}{30}=\frac{\text{no of tickets bought}}{150}[/tex]

no of tickets bought[tex]=\frac{150}{30}=5[/tex]

and no of tickets bought=No of friends

Therefore there 5 persons who bought tickets

Answer:

y= [tex]\frac{-1}{4}[/tex]x+3

Step-by-step explanation:

To write an equation for a line, we will first need to find the slope of the graph. This can be done by using the slope formula:

m= [tex]\frac{y_{2-y_{1}} }{x_{2}-x_{1}}[/tex]

Now, we can plug these points in this equation.

m= [tex]\frac{2-3}{4-0}[/tex] --> m= [tex]\frac{-1}{4}[/tex] .

Since we have derived the slope, we can simply use one of the points listed to solve for our other values by plugging them into the line formula:

y= mx+b

------------

2= [tex]\frac{-1}{4}[/tex](4)+b

2=-1+b

3= b

Therefore, the equation we get is:

y= -[tex]\frac{-1}{4}[/tex]x+3

Answer:

(Approximately)

Step-by-step explanation:

The mean absolute deviation (MAD) is defined as

[tex]MAD=\frac{\Sigma |x_{i}-\mu| }{N}[/tex]

Where [tex]\mu[/tex] is the means and [tex]N[/tex] is the total number of elements.

First, we need to find the mean:

[tex]\mu = \frac{\Sigma x_{i} }{N} =\frac{18+12+15+10+13+20+16+12+18+6}{10}= \frac{140}{10}\\ \mu=14[/tex]

Then, we calculate the difference between each value and the mean, from that difference, we are gonna use the absolute value.

18 - 14 = |4|

12 - 14 = |-2|

15 - 14 = |-1|

10 - 14 = |-4|

13 - 14 = |-1|

20 - 14 = |6|

16 - 14 = |2|

12 - 14 = |-2|

18 - 14 = |4|

6 - 14 = |-8|

Now, we sum all terms and divide them by the total number of elements, which are 14.

[tex]MAD=\frac{4+2+1+4+1+6+2+2+4+8}{14}= \frac{34}{14}\\ MAD \approx 2.4[/tex]

Therefore, the absolute deviation is about 2 points. The right answer is B.

Answer:

x = 7

LP = 6

Step-by-step explanation:

JK = 12

LK = 12

NS = 8

PS = 2x - 6

radius bisects the chords JK and LK  because it is perpendicular to them.

JK = JN + NK = 6 + 6 = 12

LK = LP + PK = 6 + 6 = 12

LP = 6

radius= root(6^2 + 8^2) = 10  then  PS = 8 = 2x -6,

8 = 2x - 6

14 = 2x

x = 7

The best example of a line of best fit will be given in option A.

What is Equation of line?

The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Some graph are shown in figure.

Now, Find the best fit of the line as;

In option A;

The line is contain almost near to the points of the graph.

So, This is the best example of a line of best fit.

In option B;

The line is not passes through any of the given points.

So, It is not best fit.

In option C;

The line is perpendicular to the graph of the points.

So, It is not best fit.

In option D;

The line is vertically with the points of the graph.

So, It is not best fit.

Thus, The best example of a line of best fit will be given in option A.

We have been an equation in polar coordinates [tex]r=10\text{sin}(\theta)[/tex]. We are asked to write our equation in rectangular coordinates.  

We know that the equation [tex]r=2b\text{sin}(\theta)[/tex] is equation of a circle with a radius [tex]|b|[/tex] and center at [tex](0,b)[/tex].

Let us find the value of b.

[tex]2b\text{sin}(\theta)=10\text{sin}(\theta)[/tex]

[tex]\frac{2b\text{sin}(\theta)}{2\text{sin}(\theta)}=\frac{10\text{sin}(\theta)}{2\text{sin}(\theta)}[/tex]

[tex]b=5[/tex]

We know that equation of a circle in rectangular coordinates is [tex](x-h)^2+(y-k)^2=r^2[/tex]

Since [tex]b=5[/tex], so radius is 5 and center is at point (0,5).

[tex](x-0)^2+(y-5)^2=5^2[/tex]

[tex]x^2+(y-5)^2=25[/tex]

Therefore, our required equation would be [tex]x^2+(y-5)^2=25[/tex].

Answer:

Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in

Part 2) The approximate value of the arc length is 13.1\ in

Step-by-step explanation:

ind the circumference of the circle

The circumference of a circle is equal to

C=2\pi r

we have

r=5\ in

substitute

C=2\pi (5)

C=10\pi\ in

step 2

Find the exact value of the arc length by a central angle of 150 degrees

Remember that the circumference of a circle subtends a central angle of 360 degrees

by proportion

\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in

Find the approximate value of the arc length

To find the approximate value, assume

\pi =3.14

substitute

\frac{25}{6}(3.14)=13.1\ in

Answer:

D.

Step-by-step explanation:

Firstly, we must look at the absolute value symbol. This means that if d is positive, it must be a number greater than 3. If d is negative, the number must be less than -3 (for the absolute value to be greater than 3.)

This results in A and D being possible solutions. HOWEVER, we must look at the ">" symbol.

Notice how the symbol solely represents "Greater than", and not "Greater than OR equal to".

This means that the number line must have OPEN circles at -3 and 3. This will give you solution D.

Answer:

679.

Step-by-step explanation:

There is either a 1, 4 or 7 in the number.

From the second guess, 189, 1 cannot be in the number , either 8 or 9 are in right place. Also 4 or 7 are in the number.

9 6 4: 9 may be in the number, also 4 or 6.

No 2,3 or 5.

2 8 6  this tells us there is no 8 ,  and 9 is the last digit.

As there is no 2 there must be a 6 in the number

So the number contains a 9 and a 6.

The third number is either a 4 or a 7, but from the  964 result it cannot be a 4 because 6 is included.

So it either 679 or 769.

But 964 had 6  in the wrong place  so the number is 679.

I think the answer is 679 because you every numbers make sense except for 679.
