Answer:

P = 0.000000028514

Step-by-step explanation:

First we are going to calculate the probability of correctly choosing exactly 4 of the winning numbers.

Remember that the probability of an event can be calculated thus:

P = \frac{favourable - cases}{total -cases}

The favorable cases resulting from choosing 4 numbers of the set of 5 winning numbers from the upper section.

The favorable cases can be calculated with a combinatorial thus:

5C4 = \frac{5!}{(5-4)!4!} =5

and the total cases are:

59C5 = \frac{59!}{(59-5)!5!} = 5006386

Then the probability is:

P = \frac{5}{5006386} = 0.000000998

and the probability of correctly choosing  the Mega Ball number is:

P = \frac{1}{35} = 0.0285714

And how both events are independent the probability of correctly choosing exactly 4 of the winning numbers and the Mega Ball number is:

P = (0.000000998)(0.0285714)

P = 0.000000028514

Describe this pattern and Find the next 3 numbers in the pattern 3.5, 13, 41.5, 127, , , . also explain in a easy way how you fi
notsponge [240]

You have:

a_1=3.5,\\ \\a_2=13,\\ \\a_3=41.5,\\ \\a_4=127.

Find

a_2-a_1=13-3.5=9.5,\\ \\a_3-a_2=127-41.5=28.5=9.5\cdot 3,\\ \\a_4-a_3=127-41.5=85.5=28.5\cdot 3=9.5\cdot 3^2.

This gives you the rule how to find next terms:

1.

a_5-a_4=9.5\cdot 3^3,\\ \\a_5-127=256.5,\\ \\a_5=127+256.5=383.5.

2.

a_6-a_5=9.5\cdot 3^4,\\ \\a_6-383.5=769.5,\\ \\a_6=383.5+769.5= 1153.

3.

a_7-a_6=9.5\cdot 3^5,\\ \\a_7-1153=2308.5,\\ \\a_7=1153+2308.5=3461.5.

Answer: next 3 terms are 383.5, 1153 and 3461.5.

galben [10]

Answer:

18 t-shirts.

Step-by-step explanation:

Trey made a total profit $106 by selling t-shirts and hats. $34 of that profit was from selling hats, subtract 34 from 106 and you will get 72. So he made a profit of $72 in selling t-shirts. The t-shirts were $4 each, so if you divide 72 by 4 you will get 18. Meaning he sold 18 shirts.
