Answer:

Option A: $1

Step-by-step explanation:

Mr. Boyle played WinOne lottery game = 100 times

He spent on tickets = 100 × $2.00 = $200

Prize money for WinOne game = $150.00

He won 2 times and got prize = $150.00 × 2 = $300.00

His net winning prize would be = 300 - 200 = $100.00

Mr. Boyle's net winning per turn is = 100 / 100 = $1.00

Option A : $1 is the correct answer.

Mr Boyle spends 2 * 100 = $200 in playing 100 games
His winning come to 2*150 = $300
so net winning = $100
winnings per turn = 100 / 100 = $1

(5 points) The population of a state changes due to births, deaths, and immigration. The annual birth rate is 14.3 births per 10

LUCKY_DIMON [66]

Answer:

The population growth rate is of 1.86%.

Step-by-step explanation:

Population growth rate:

Immigration plus births subtracted by emigration and deaths.

In this question, we have that:

Birth: 14.3 per 1000

Death: 11.8 per 1000

Immigrations: 21.6 per 1000

Emigrations: 5.5 per 1000

Rate:

$\frac{14.3 + 21.6 - 11.8 - 5.5}{1000} = \frac{18.6}{1000} = 0.0186$

As a percentage:

Multiply by 100%. So

0.0186*100% = 1.86%

The population growth rate is of 1.86%.

Find a1, for the given geometric series. Round to the nearest hundredth if necessary. Sn= 86,830, r= 2.2, n=4

larisa86 [58]

Answer:

4,646.30

Step-by-step explanation:

The sum of n terms of geometric sequence can be calculated using formula

$S_n=\dfrac{a_1(1-r^n)}{1-r}$

In your case,

$S_n=86,830\\ \\r=2.2\\ \\n=4\\ \\a_1=?$

Substitute into the formula:

$S_4=\dfrac{a_1(1-2.2^4)}{1-2.2}\\ \\86,830=\dfrac{a_1(1-23.4256)}{-1.2}\\ \\-104,196=a_1(-22.4256)\\ \\22.4256a_1=104,196\\ \\a_1=\dfrac{104,196}{22.4256}\approx 4,646.30$
