In a recent year, 304 of the approximately 300,000,000 people in the United States were struck by lightning. Estimate the prob

umka2103 [35]

Answer:

$\frac{19}{18,750,000}=0.0000010133333333$

Step-by-step explanation:

We have been given that in a recent year, 304 of the approximately 300,000,000 people in the United States were struck by lightning.

$\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Number of possible outcomes}}$

$\text{P( A randomly selected person in the United States will be struck by lightning this year)}=\frac{304}{300,000,000}$

$\text{P( A randomly selected person in the United States will be struck by lightning this year)}=\frac{19}{18,750,000}$

$\text{P( A randomly selected person in the United States will be struck by lightning this year)}=0.0000010133333333$

Therefore, the probability that a randomly selected person in the United States will be struck by lightning this year is $\frac{19}{18,750,000}=0.0000010133333333$ .

Remove the parentheses and take out the constansts.

$(7 x 3) x^{2} x^{5} y^{3} y^{8}$

Simplify 7 x 3 to 21.

$21x^{2} x^{5} y^{3} y^{8}$

Use the product rule: $x^{a} x^{b} = x^{a + b}$

$21x^{2 + 5}y^{3+8}$

Simplify 2+5 to 7.

$21x^{7}y^{3+8}$

Simplfiy 3 + 8 to 11.

$21x^{7}y^{11}$
