Mathematics

Elden [556K]2 years ago

The consideration of the Age Distribution of the Population of the United States South Region shows that:

<h3>South Region:</h3>

Section: 1: Child Dependency Ratio: =31.4160%

Section: 2: Old-age Dependency Ratio: 18.9205%

Section: 3: Age Dependency Ratio: 50.3364%

Section: 4: Interpret: About 31% of the children and 19% of old people of the South region depend on their working adults.

Section: 5: Extend: This implies that more than 50% of children and old people in the United States depend on 50% of the working population for survival.

<h3>Data and Calculations:</h3>

Age                            Total   # Northeast   # Midwest   # South      # West

Both sexes             306,108      54,782         66,104      113,274        71,946

Under 15 years        62,155       10,034          13,180       23,671        15,269

15 to 64 years       204,775        37,101        44,209       75,347         48,117

65 years and older 39,178         7,647           8,715        14,256         8,560

<h3>South Region:</h3>

Section: 1: Child Dependency Ratio: =31.4160% (23,671/75,347 x 100)

Section: 2: Old-age Dependency Ratio: 18.9205% (14,256/75,347 x 100)

Section: 3: Age Dependency Ratio: 50.3364% (37,927/75,347 x 100)

Section: 4: Interpret: About 31% of the children and 19% of old people of the South region depend on their working adults.

Section: 5: Extend: This implies that more than 50% of children and old people depend on the working population.

Thus, the records show that a little over 50% of the population depends on less than 50% population for survival.

Kaitlyn saves $6 each week. After correctly carrying out the Solve step of the five-step problem-solving plan, which solution sh
ch4aika [34]

Answer:

1. 10 weeks

Step-by-step explanation:

Apparently, we want to find the number of weeks (w) that Kaitlyn must save $6 in order to have a total of $60.

... $6 × w = $60

Divide by $6 to get ...

... w = $60/$6 = 10

Kaitlyn must save for 10 weeks (if she starts with a balance of 0).

_____

<em>Comment on the problem statement</em>

The problem reads like we came in somewhere in the middle of it. We don't know what other steps you've been asked to perform, or any of the details of the problem you're asked to solve. We don't have Kaitllyn's initial balance, for example, which is essential to determining how long she must save. (If Kaitlyn's initial balance is $33, for example, she must only save for 4.5 weeks.)

Cellus
Paladinen [302]

Answer:

9/4

Step-by-step explanation:

The quadratic function can be rearranged to look like this:

x^2-3x-1=0

Now we see that the constant b is equal to -3. Using the hint, we find:

(-3/2)^2=9/4

Hope that helps!

30 points! Find the four arithmetic means between -17 and 32.
bearhunter [10]

Answer: - 7.2 , 2.6 , 12.4 and 22.2

Step-by-step explanation:

Let the arithmetic means be p , q , r ,s , therefore , the sequence becomes:

-17 , p , q , r , s , 32

The first term (a ) = -17

Last term (L) = 32

common difference (d) = ?

number of terms (n ) = 6

We will use the formula for calculating the last term to find the common difference. That  is

L = a + (n - 1 ) d

Substituting the values , we have

32 = -17 + (6-1) d

32 = -17 + 5d

32 + 17 = 5d

49 = 5d

Therefore: d = 9.8

We can therefore find the values of p , q , r , and s

p is the second term , that is

p = a + d

p = -17 + 9.8

p = -7.2

q = a + 2d

q = - 17 + 19.6

q = 2.6

r = a + 3d

r = - 17 + 29.4

r = 12.4

s = a + 4d

s = - 17 + 39.2

s = 22.2

Therefore : the arithmetic means are : - 7.2 , 2.6 , 12.4 and 22.2
