Step-by-step explanation:

f(0) means x=0

We use the f(x) when x<5

f(0) = 0+4 = 4

f(6) means x=6  

We use the f(x) when 5≤x<7

f(6) =8

Answer:

n=0

Step-by-step explanation:

3n+5+2n=5+n+6n-n​

move like terms together

3n+2n+5=5+n+6n-n

simplify down

5n+5=5+6n

subtract 5n from each side

5=5+n

subtract 5 from each side

0=n

Answer:

a

[tex]\mu  =  127[/tex]

b

[tex]\sigma  =  9.76[/tex]  

c

[tex]z-score  =  3.18 [/tex]

d

Yes, 158 players out of 508 is an unusual number of men born in the first 3 months of the year because the z score of 158  is  greater than  3( Note :the probability of  z-score = 3 is  97%)

e

The correct option is  option 3

Step-by-step explanation:

From the question we are told that

   The population proportion is  p =  0.25

   The sample size is  n =  508

Generally the mean is  mathematically represented as  

     [tex]\mu  =  np[/tex]

=>   [tex]\mu  =  508 * 0.25[/tex]

=>   [tex]\mu  =  127[/tex]

Generally the standard deviation is mathematically represented as

     [tex]\sigma  =  \sqrt{ np (1-p)}[/tex]

=>   [tex]\sigma  =  \sqrt{ 508 * 0.25 (1-0.25)}[/tex]    

=>    [tex]\sigma  =  9.76[/tex]  

Generally the z-score of  158 is mathematically represented as

    [tex]z-score  =  \frac{158 - 127}{9.76}[/tex]

=>  [tex]z-score  =  \frac{158 - 127}{9.76}[/tex]

=>  [tex]z-score  =  3.18 [/tex]

Yes, 158 players out of 508 is an unusual number of men born in the first 3 months of the year because the z score of 158  is  greater than  3( Note :the probability of  z-score = 3 is  97%)

What this means is that the almost the whole  professional hockey league player are born in the first month which is unusual

Answer:

[tex]y = -x -2[/tex]

Step-by-step explanation:

Slope-Intercept form of the line

Any given line with slope m and y-intercept b can be written as:

y=mx+b

We need to find the equation of a line parallel to

2x + 2y = 6

Dividing by 2:

x + y = 3

Solving for y:

y = -x + 3

Comparing with the slope-intercept form of the line:

m = -1

Parallel lines have the same slope, thus the required line must have a slope m = -1.

Since we have a point through which the line passes, we use the point-slope form:

y - k = m ( x - h )

Where (h,k) is the point.

The required equation of the line is:

y - (-5) = -1 (x - 3)

Operating:

y + 5 = -x + 3

Solving for y:

[tex]\boxed{y = -x -2}[/tex]

Answer:

-7/4

Step-by-step explanation:

Since we have two points we can use the slope formula

m = ( y2-y1)/(x2-x1)

  = ( 3 - -4)/( -3 -1)

  ( 3+4) / ( -3 -1)

   7/-4

   -7/4

Step-by-step explanation:

A Venn diagram, also called primary diagram, set diagram or logic diagram, is a diagram that shows all possible logical relations between a finite collection of different sets. These diagrams depict elements as points in the plane, and sets as regions inside closed curves. A Venn diagram consists of multiple overlapping closed curves, usually circles, each representing a set. The points inside a curve labelled S represent elements of the set S, while points outside the boundary represent elements not in the set S. This lends itself to intuitive visualizations; for example, the set of all elements that are members of both sets S and T, denoted S ∩ T and read "the intersection of S and T", is represented visually by the area of overlap of the regions S and T.[1][2] In Venn diagrams, the curves are overlapped in every possible way, showing all possible relations between the sets. They are thus a special case of Euler diagrams, which do not necessarily show all relations. Venn diagrams were conceived around 1880 by John Venn. They are used to teach elementary set theory, as well as illustrate simple set relationships in probability, logic, statistics, linguistics, and computer science.

A Venn diagram in which the area of each shape is proportional to the number of elements it contains is called an area-proportional (or scaled Venn diagram).

10 of those are red cards which makes it 10/40 which is simplified to 1/4.

Answer:

10:30 (simplified- 1:3)

Step-by-step explanation:

there are 10 red cards so the first number would be 10

the other cards are black hearts and blue cards, if you add them together that is 30 cards, therefore, the answer is 10:30

Answer: The distributive property.

Step-by-step explanation:

(x^4 +3x^3 -2x^3)(-5x^2 +x) = (x^4 +3x^3 -2x^3)(-5x^2)+(x^4 +3x^3 -2x^3)(x) is an example of the Distributive Property.

It is a property of multiplication and division. It states that when either of these operations is written outside a bracket, the operation must be applied to all terms inside the bracket when it is opened.

(a + b)c = ac + bc

It is given that:

(x^4 +3x^3 -2x^3)(-5x^2 +x) = (x^4 +3x^3 -2x^3)(-5x^2)+(x^4 +3x^3 -2x^3)(x).

We can see that when the bracket of the second term is opened, the first term is multiplied across all the terms that were within the bracket.

This is a feature of the distributive property. It is called the distributive property of multiplication.

Therefore, we have found that the equation (x^4 +3x^3 -2x^3)(-5x^2 +x) = (x^4 +3x^3 -2x^3)(-5x^2)+(x^4 +3x^3 -2x^3)(x) is an example of the Distributive Property.

17/20 is the probability that their eyes are green or Hafzel.

It is a branch of mathematics that deals with the occurrence of a random event.

Given,

The number of students having Green eyes =6

The number of students having Blue eyes =3

The number of students having Hafzel eyes =11

The total number of students=11+3+6

=20

The probability that their eyes are green is 6/20

The probability that their eyes are Hafzel is 11/20

The probability that their eyes are green or  Hafzel

6/20 + 11/20

= 17/20

Hence,  17/20 is the probability that their eyes are green or Hafzel.

Answer:

y=3/2x+3

Step-by-step explanation:

The slope is 3/2. The slope is m. We plug 3/2 into our equation.

y=mx+b

y=(3/2)x+b

Now we have to find b.

B is 3 because that's where it crosses the y axis.

So y=3/2x+3

Answer: 40320 sequence to test.

Step-by-step explanation:

we have given the following data:

No of wires which need to be attached to a circuit board = 8

What We need to find is the number of possible sequences of assembly that must be tested.

Using our multiplication rule of counting we arrive at,

Number of possible sequences of assembly is given by

8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

= 40320

i.e. there are 8 choices for the first wire, 7 choices for the second wire, 6 choices for the third wire, 5 choice for the fourth wire same till the 8th wire.

Hence, there are 40320 possible sequences of assembly.
