Answer:

39858075

Step-by-step explanation:

Hello,

One basic way to see it is to compute the values.

75 = 25 * 3

225 = 75 * 3

675 = 225 * 3

etc ...

We can notice that this is multiplied by 3 every 10 years so we can compute as below.

year population

1970 25

1980 75

1990 225

2000 675

2010 2025

2020 6075

2030 18225

2040 54675

2050 164025

2060 492075

2070 1476225

2080 4428675

2090 13286025

2100 39858075

So the correct answer is 39858075

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Giving that ai +bj 5i-2j are perpendicular find the value of a if b=3

Nonamiya [84]

Answer:

a = $\frac{6}{5}$

Step-by-step explanation:

Given

ai + bj and 5i - 2j are perpendicular and b = 3, that is

ai + 3j and 5i - 2j are perpendicular, then

The scalar product = 0 , that is

5a - 6 = 0 ( add 6 to both sides )

5a = 6 ( divide both sides by 5 )

a = $\frac{6}{5}$

If an urn has 5 white balls 10 red balls what is the probability that 5 randomly selected balls contain exactly 3 white balls?

kondaur [170]

Answer:

0.15

Step-by-step explanation:

Without Mincing words let us dive straight into the solution to the question above. We are given the following information which is going to aid in solving this particular question.

====> It is given, that there are 5 white balls and 10 red balls. Hence, the number of the total balls = 5 white balls + 10 red balls = 15 balls.

Therefore, the probability that 5 randomly selected balls contain exactly 3 white balls = $\left[\begin{array}{ccc}5\\3\end{array}\right]$ × $\left[\begin{array}{ccc}10\\2&\end{array}\right]$ ÷ $\left[\begin{array}{ccc}15\\3\\\end{array}\right]$ = 450 ÷ 3003 = 0.15

A company that has 350000 shares declares an annual gross profit of $2450665, pays 18.5% of this in tax, and reinvests 25% of th

podryga [215]

Gross profit, G = $2450665

Tax, t=18.5%

reinvestment, r = 25%

Total dividends

= G(1-t)(1-r)

=2450665*(1-0.185)(1-0.25)

=1497968.98

Dividend per share

=1497968.98/350000

=4.280

Earnings per share

EPS = Net profit / number of shares

= 2450665(1-0.185)/350000

=5.7065

Current price = 43.36

P/E ratio

= Current price/EPS

= 43.36/5.7065

= 7.598

=7.6 to one decimal place.
