Answer 1
Answer:

Answer:

(a) Mean =243.0909

(b) Median = 240

In other words it is the middle value of the data arranged in order.

(c) Mode =  221  and 257

(d) Mid Range =   247.5

e)

Variance = 1578.5037

Standard Deviation = 39.730

Range = 309-186= 123

(e)  No the results are not  likely to be representative of all players in that​ sport's league because they are not similar.

Step-by-step explanation:

First arranging the data in ascending order

186 187 221 221 229 240 257 257  274  293    309

(a) Mean = Sum of observations/ No of observations

       = 186 + 187 + 221 +221 + 229 + 240 + 257 + 257 + 274 + 293 + 309 /11

= 2674/11=

= 243.0909

(b) Median for un grouped data is

Here n = 11 and n/2 = 11/2 is not an integer

Median = Results obtained by ([n/2] +1) player

                   = (11/2 +1) = 6th player in ordered data

                = 240

In other words it is the middle value of the data arranged in order.

(c) Mode = Most frequent values.

There are two modes : 221  and 257 . These both values occur repeatedly.

(d) Mid Range = Maximum Value + minimum value/ 2= 186+ 309/2=  247.5

Now we will find the variance and standard deviation

The variance is given by

s² =  (186-243.0909)²+ (187-243.0909)²+ (221-243.0909)²+ (221 -243.0909)²+(229-243.0909)²+ (240-243.0909)²+( 257-243.0909)²+ (257 -243.0909)²+ (274-243.0909)²+ ( 293-243.0909)²+    (309 -243.0909)²/11-1

s²=  3259.370 + 3146.139+ 488.008+ 488.008+ 198.553+ 9.554+ 193.463 + 193.463 + 955.372 +  2509.098 + 4344.009/10

s²= 15,785.037/10= 1578.5037

And Standard Deviation = s= √1578.5037= 39.730

Variance = 1578.5037

Standard Deviation = 39.730

Range = 309-186= 123

(e)  No the results are not  likely to be representative of all players in that​ sport's league because they are not similar.

Determine the factors of 5x2 + 29x _ 6

Answers

The answer is (x + 6)(5x - 1).

5x² + 29x - 6 = 5x² + 30x - x - 6 =
                      = (5x · x + 5x · 6) - (x + 6) =
                      = 5x(x + 6) - 1(x + 6) =
                      = (x + 6)(5x - 1)

Answer:

The factors of given equation 5x^2+29x-6 is  (5x-1)(x+6)

Step-by-step explanation:

Given equation 5x^2+29x-6

We have to determine the factors of given equation.

Quadratic equation is an equation with  highest degree 2.

Consider the given quadratic equation 5x^2+29x-6

We can solve the  quadratic equation 5x^2+29x-6  using middle term splitting method.

splitting middle term can be done by writing middle term in such a way that  the product of coefficient is the product of remaining two terms.

29x can be written as 30x-1x

\Rightarrow 5x^2+29x-6

\Rightarrow 5x^2+30x-x-6

Taking 5x common from first two terms and  -1 from last two terms , we have,

\Rightarrow 5x(x+6)-1(x+6)

5x^2+29x-6=(5x-1)(x+6)

Thus,  the factors of given equation 5x^2+29x-6 is  (5x-1)(x+6)

0.36p=3.6
p= (3.6)/(0.36)
p=10

PLS HELP. The cost of printing a flyer to spread knowledge of an organization that you run is a flat rate of $9 plus $0.05 per copy. Let C represent the total cost of printing and x represent the number of copies. Write in symbolic form an equation that will relate C and x. Organize the data into a table of values. Begin with 500 copies, increase by increments of 500, and end with 2500 copies. How much would it cost to print 2500 flyers and what equation would you use?

Answers

The cost of printing a flyer to spread knowledge of an organization that you run is a flat rate of $9 plus $0.05 per copy. 

We are given the equation: 
9.00+0.05x=C

500 copies:

Equation - 9.00+0.05(500)=C

1500 copies: 

Equation - 9.00=0.05(1500)=C 

2500 copies: 

Equation - 9.00=0.05(2500)=C 

C = 9 + 0.05x = 2500  flyers will cost $134
u would need to spend about 100-500 dollars on copies

Alessandro wrote the quadratic equation –6 = x2 4x – 1 in standard form. what is the value of c in his new equation?

Answers

Standard form for quadratic equations is:

0 = ax² + bx + c 

To make Alessandro's first equation in standard form, you must make the constant on the left side of the equation 0.

To do this, we should add 6 to each side to cancel out the -6 on the left side of the equation, making its value 0.

Alessandro's new equation is:

-6 + 6 = x² + 4x - 1 + 6

If we simplify this equation, we get:

0 = x² + 4x + 5

Therefore, knowing that the equation above is in the form ax² + bx + c, we can determine that the value of c in Alessandro's new equation is 5.

Answer:

c=5
