Answer:

1/625

Step-by-step explanation:

Exponent Rule: $(b^m)(b^n) = b^{m+n}$

Exponent Rule: $b^{-m}=\frac{1}{b^m}$

5⁻⁸ · 5⁴ = -8 + 4 = -4

5⁻⁴

1/5⁴

<h3><u>Given</u></h3>

Rolled A six-sided dice.

P(Prime) as percentage

<h3><u>Solution</u></h3>

Total Possible Outcomes= 1, 2, 3, 4, 5, 6.

So, No. of possible Outcomes= 6

Prime number of the dice= 2, 3, 5

So, No. of favorable outcomes of Prime number= 3

$\text{Probability of an event= }$

$\frac{ \text{favorable no. of outcome}}{ \text{total no. of outcome}} \times 100$

$\text{Percentage of Probability getting P(Prime) number on face of dice} =$

$\frac{3}{6} \times 100 \\ \\ = \cancel \frac{3}{6} \times 100 \\ \\ = \frac{1}{ \cancel2} \times \cancel{100} \\ \\ = 50\%$

$\therefore \% \text{ Probability of getting prime number is \red{50} \red\%}$

The general form of the equation of a circle is x2 + y2 + 42x + 38y − 47 = 0. The equation of this circle in standard form is (x

Korvikt [17]

For the center of this circle the right choice will be choice B. (-21,-19)

and its radius sqrt849 = 849^(1/2) so choice B. is right for this too

hope this will help you
