Answer:

Median income has not changed

Mean income has increased

Step-by-step explanation:

Initial number of houses = 6

Earning per household = $40,000

The initial mean :

$(40,000 * 6) / 6 = $40000

Initial median :

40000, 40000, 40000, 40000, 40000, 40000

= 1/2(n+1)th term,

Median = 40000

A 7th household earns 4,000,000

Mean = ((40000*6) + 4,000,000) / 7 = $605,714

Median = 1/2(n+1)th term

40000, 40000, 40000, 40000, 40000, 40000, 4000000

Median = 4th term = 40000

Answer:

(x+5) metres

Step-by-step explanation:

correct question

The rectangle below has an area of x^2+8x+15 square meters and a width of x+3 meters. What expression represents the length of the rectangle?

Area of the rectangle = Length * width

Factorize the area

A(x) =  x^2+8x+15

A(x) = x^2+3x+5x+15

A(x) = x(x+3) + 5(x+3)

A(x) = (x+3)(x+5)

Since the width is x+3, the length of the rectangle will be (x+5) metres

Answer:

22ft

Step-by-step explanation:

Find the diagram attached

Since the triangles are mirror images of each other, this shows that they are similar triangles

Taking the ratio of the sides of the triangle and equating it to a constant, we will have;

5.5/4 = x/16

Cross multiply

4 * x =5.5 * 16

4x = 88

x = 88/4

x = 22ft

Hence the required value of x is 22ft

Answer:

12 inches

Step-by-step explanation:

3 feet = 1 yard

1/3 yard = 1 foot

1 foot = 12 inches

If Brad cuts each log by 12 he will have 48 pieces of cut logs. I hope this helps you, have a great day!

Answer:

48

Step-by-step explanation:

4x12=48

Answer:

Step-by-step explanation:

a systems of equations can be made from the information on the problem

x+y=48

x=2y+3

since x= 2y+3 substitute 2y+3 in the firat equation to get:

(2y+3)+y=48  -> 3y+3=48 -> 3y=45  -> y=15

plug in 15 for y in the second equation to solve for x

x+15 =48 --> x=33

Answer:

  3)  ΔQRS ~ ΔQFG

  5)  ΔRST ~ ΔGFE

Step-by-step explanation:

3) Shortest to longest, the side ratios are ...

  RQ : QS = 6 : 12 = 1 : 2 (reduced)

  FQ : QG = 2 : 4 = 1 : 2 (reduced)

  ΔQRS ~ ΔQFG

5) FE : EG : GF = 18 : 24 : 26 = 9 : 12 : 13 (reduced)

  ST : TR : RS = 27 : 36 : 39 = 9 : 12 : 13 (reduced)

  ΔRST ~ ΔGFE

Answer:

The answer is 36

Step-by-step explanation:

Because 39+1=40

So then 40-24=16

and then divided by 6 is 36 because when you divide you multiply

Answer:

B

Step-by-step explanation:

points (1,4) and (8,11) cross through y=x+3

Let A be the first sequence, and denote by [tex]a_n[/tex] the n-th term in A.

Consider the forward differences of A :

16 - 7 = 9

30 - 16 = 14

49 - 30 = 19

73 - 49 = 24

Call this sequence of first differences B, so that for n ≥ 1,

[tex]b_n=a_{n+1}-a_n[/tex]

where [tex]b_n[/tex] is the n-th term of B.

Now consider the forward differences of B, which is another sequence we'll call C :

14 - 9 = 5

19 - 14 = 5

24 - 19 = 5

Then if [tex]c_n[/tex] is the n-th term of C, we have for all n ≥ 1,

[tex]c_n=b_{n+1}-b_n=5[/tex]

which gives

[tex]b_{n+1} = b_n+5[/tex]

This tells us B is an arithmetic sequence - the first term is 9 and the difference between consecutive terms is 5, so we have for n ≥ 1,

[tex]b_n = 9 + 5(n-1) = 5n + 4[/tex]

Plug this into the recurrence for A :

[tex]a_{n+1} = a_n + b_n = a_n + 5n + 4[/tex]

We don't need to solve for [tex]a_n[/tex], fortunately; we just want the next term, which would be

[tex]a_6 = a_5 + 5^2 + 4 = 73 + 25 + 4 = \boxed{102}[/tex]

Answer:

zeros are ±2

Step-by-step explanation:

y = x² - 4

this can be factored into (x+2)(x-2)

if you then set each factor equal to zero you will get zeros of ±2
