Answer: 2.5722 .
_____________________________________________________
Explanation:
_________________________________________________
log(base " $\pi$ " of 19 = y ? ; Solve for "y" ;
__________________________________________________
$\pi$ ^ (y) = 19 ; Solve for "y" ?
__________________________________________________
Take the "ln" (that is, "natural logarithm", of both sides:
__________________________________________________
ln [ $\pi$ ^ (y) ] = ln 19 ;
__________________________________________________
y * ln $\pi$ = ln 19 .
__________________________________________________
Use "3.1416" as an approximation for: " $\pi$ " ;
__________________________________________________
y * ln (3.1416) = ln 19 ;
__________________________________________________
Divide EACH side of the equation by: " [ ln (3.1416) ]" ; to isolate "y" on one side of the equation; and to solve for "y"; (Use a calculator to do this) ;
_________________________________________________________
y * ln (3.1416) / [ ln (3.1416) ] = ln 19 / [ ln (3.1416) ] ;
________________________________________________________
y = ln 19 / [ ln (3.1416) ] ;
_______________________________________________________
y = 2.5721639670047041 ;

→ round to nearest 4 (FOUR) decimal places;
_______________________________________________________
→ y = 2.5722 .

There is a game at the carnival that costs $20 to play. There are two outcomes: either you win $100 , or you lose. To play you r

Taya2010 [7]

Outcome on winning = $100 - $20 = $80
Outcome on losing = $20

Probability of winning = 1/6
Probability of losing = 5/6

Expected Value = 1/6 (80) +5/6(-20) = -3.333

This shows on average from each game, the game earns $ 3.333.

So, if 1000 such games are played, the game will earn 1000 x 3.33 = $3330

So, the answer to this question is option A

standard automobile license plates in a country display 3 numbers, followed by 2 letters, followed by 2 numbers. how many differ

RoseWind [281]

The system of standard automotive license plates allows for a variety of standard plates is 39917124 ways.

<h3>Define the term permutation?</h3>

The number of potential arrangements for a given set is assessed mathematical terms, but this procedure is referred to as permutation.
The arrangement's order is essential when using permutations.

For the stated data;

Standard car license plates in a nation typically have 3 digits, 2 letters, and 2 numbers.

There are total 9 digits (0 - 9).

There are total 26 letter (A - Z)

Repetitions of letters and numbers given allowed.

Thus, numbers and the letters ca be arranged as;

1st place = 9 ways.

2nd place = 9 ways.

3nd place = 9 ways.

4th place = 26 ways.

6th place = 26 ways.

7th place = 9 ways.
