Let's go shape by shape!

The area of a rectangle can be calculated as follows:

L * W = area where L = length and W = width

The area of a trapezoid can be calculated as follows:

\frac{( b_{1} +  b_{2})*H}{2} = area
where b1 and b2 = lengths of the base and H = height of the shape

The area of a parallelogram can be calculated as follows:

B * H = area where B = length of the base and H = height of the shape

2. Last year, 70% of 1 million Philadelphians got their flu shots. About 2% of people who got
alexgriva [62]

The conditional probability that a Philadelphian who got the flu got a flu shot is of:

0.4375 = 43.75%.

<h3>What is Conditional Probability?</h3>

Conditional probability is the probability of one event happening, considering the outcome of a previous event.

The formula is presented as follows:

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which each probability in the formula is described as follows:

  • P(B|A) is the probability of the event B happening, given that the event A happened.
  • P(A \cap B) is the probability of both the events A and B happening.
  • P(A) is the probability of the event A happening.

In the context of this problem, the events are described as follows:

  • Event A: Got the flu.
  • Event B: Got the flu shot.

The probability of people who got the flu is obtained as follows:

  • 2% of 70%. (got the shot).
  • 6% of 30%. (did not get the shot).

Hence:

P(A) = 0.02 x 0.7 + 0.06 x 0.3 = 0.032.

The probability of both getting the flu and the shot is:

P(A and B) = 0.02 x 0.7 = 0.014.

Hence the conditional probability that a Philadelphian who got the flu got a flu shot is calculated applying the conditional probability formula as follows:

P(B|A) = P(A and B)/P(A) = 0.014/0.032 = 0.4375 = 43.75%.

The two fastest times in past 20 years for the girls 200-meter run at Clarksville elementary school are 27.97 seconds and 27.93
Delvig [45]

Answer:

The answer to your question is: no

Step-by-step explanation:

Data

Fastest time = 27.93 s

Second fastest time = 27.97 s

Claire's time = 27.99 s

Just remember that to win a race, the athete that wins must register the lowest time.

Substract Claire's time from the fastest time, if the result is positive, Claire ran slower, if the result is negative Claire ran faster than the previous Girls.

Difference 1 = 27.99 - 27.93 = 0.06 positive, Claire ran slower

Difference 2 = 27.99 - 27.97 = 0.02 positive, Claire ran slower.
