A recent survey by the cancer society has shown that the probability that someone is a smoker is P(S)=0.19. They have also determined that the probability that someone has lung cancer, given that they are a smoker is P(LC|S)=0.158. What is the probability (rounded to the nearest hundredth) that a random person is a smoker and has lung cancer P(S∩LC) ?0.35

Answer 1

Answer:

Answer:

P (S∩LC) = 0.03

Step-by-step explanation:

We are given that the probability that someone is a smoker is P(S)=0.19 and the probability that someone has lung cancer, given that they are a smoker is P(LC|S)=0.158.

Given the above information, we are to find the probability hat a random person is a smoker and has lung cancer P(S∩LC).

P (LC|S) = P (S∩LC) / P (S)

Substituting the given values to get:

0.158 = P(S∩LC) / 0.19

P (S∩LC) = 0.158 × 0.19 = 0.03

Angles K and 3 are congruent because they’re vertical angles. Then, angles 3 and 1 are congruent. The supplements of angles 3 and 1 are congruent because supplements of congruent angles are congruent. Both lines are parralel because or the arrangement of the angles. That is the best way I can describe it.

Answer:

the answer is 1

Step-by-step explanation:

because I did 127+53=180

then you have to subtract 53 from each other 180-53=127

then you have to divide 127 and 127

then you go to gave you last answer is 1

Answer:

Step-by-step explanation:

$\log_(5)((2)/(3)x-2)+2=0\n\n\log_(5)((2)/(3)x-2)=-2\n\n$

This means that 5 to the power of -2 is $((2)/(3)x-2)$ , meaning that:

$(2)/(3)x-2=5^(-2)=(1)/(25) \n\n(2)/(3)x=(51)/(25) \n\n2x=(153)/(25) \n\nx=(153)/(50)=3.06$

What is the measure of an interior angle of a regular polygon iwth 15 sides

Answers

To find the measure of an interior angle of any regular polygon, we use the formula:

180 * (n-2) / n,

where n is the number of sides in the regular polygon.

Therefore, if there are 15 sides in the regular polygon, your answer would be

180 * (15-2) / 15,

or when simplified,

180 * 13 / 15

2340 / 15

156 degrees.

Thus, the measure of an interior angle of a regular polygon with 15 sides is 156 degrees.
