Answer:

96 is the number of original women investors.

Step-by-step explanation:

Let X be the number of young women in the initial group.  They raised 480000, so the average payment per person was (480000/X).  

When 4 pull out, the new average is (480000/(X-4)).  We are told that this new average required the remaining women (X-4) to add another 20000.

The four women therefore had contributed 20000 in total, making their average 20000/4 = 5000 each.  

This would have been the same amount contributed by all X women.  Thus, we can set the average (480000/X) equal to 5000

(480000/X) = 5000

(480000) = 5000X

(480000)/5000 = X

X = 96

<u><em>The original number of women was 96.</em></u>

===

Check

(96 Women)(5000/Woman) = 480000  CHECKS

(4 Women pull out)*(5000) = 20000 that needs to be added to stay at 480000.  CHECKS

Jacqueline records the height of her plant for three
Alex777 [14]

Answer:

Each month: y = 12(3x - 7)

12 months: y = 36x - 42

Step-by-step explanation:

We are told that her plants grow by 7" subtracted from the product of a number and 3" inches each month.

Now, let the number be x.

Also, let y denote how much her plants grow each month.

Thus, each month, her plants will grow by;

y = 3x - 7

Since 1 month, it grows by y = 3x - 7

Then, for 12 months, it will grow by;

y = 12(3x - 7)

y = 36x - 42

If ax7yb is a term from the expansion of (x + y)12, describe how to determine its coefficient a and missing exponent b without w
DerKrebs [107]

<u>ANSWER</u>

a) Use the homogeneous property of the binomial expansion to find the missing exponent

b) Use the binomial theorem to find the coefficient

<u>EXPLANATION</u>

The given binomial expansion is:

(x+y)^{12}

When we compare this to

(a + b) ^{n}

We have

n = 12

Therefore the of each term in the expansion must be 12.

\implies \: 7 + b = 12

b = 12 - 7

b = 5

Since the coefficient of x and y are unity, we use the formula

^{n} C_r =  \frac{n!}{(n - r)!r!}

to find the coefficient.

Where n=12 and r=5(the exponent of the y-term).

Therefore the coefficient is

^{12} C_5=  \frac{12!}{(12- 5)!5!}

^{12} C_5=  \frac{12!}{7!5!}

^{12} C_5=  \frac{12 \times 11 \times 10 \times 9 \times 8 \times 7!}{7! \times 5 \times 4 \times 3 \times 2 \times 1}

When we simplify further we get:

^{12} C_5= 11 \times 9 \times 8 = 792
