I NEED HELP ASAP PLEASE. I CANT THINK TOO MUCH RN SO YEAH PLEASE HELP

BaLLatris [955]

There are 60 min per hour.
There are 24 hours in one day, so there are 60 times 24= 1,440 minutes in a day.
Person A: for 45 minutes per day had a heart rate of 150, and for 1,395 minutes per day had a heart rate of 60.
This means that her heart rate totaled (45x150) + (1,395x60) = 90,450 beats per day.
Person B: for 1,440 minutes per day had a heart rate of 72 beats per minute.
This means that her heart rate totaled (1,440x72) = 103,680 beats per day.

So for 365 days: 365(103,680-90,450)= 4,828,950-this is the number of beats MORE per year of Person B than Person A.

Assuming the probability of a single sample testing positive is 0.15, find the probability of a positive result for two samples

Grace [21]

Answer:

$P(Positive\ Mixture) = 0.2775$

The probability is not low

Step-by-step explanation:

Given

$P(Single\ Positive) = 0.15$

$n = 2$

Required

$P(Positive\ Mixture)$

First, we calculate the probability of single negative using the complement rule

$P(Single\ Negative) = 1 - P(Single\ Positive)$

$P(Single\ Negative) = 1 - 0.15$

$P(Single\ Negative) = 0.85$

$P(Positive\ Mixture)$ is calculated using:

$P(Positive\ Mixture) = 1 - P(All\ Negative)$ ---- i.e. complement rule

So, we have:

$P(Positive\ Mixture) = 1 - 0.85^2$

$P(Positive\ Mixture) = 1 - 0.7225$

$P(Positive\ Mixture) = 0.2775$

<em>Probabilities less than 0.05 are considered low.</em>

<em>So, we can consider that the probability is not low because 0.2775 > 0.05</em>

leg^2 + leg^2 = hyp^2

5^2 + 12^2 = hyp^2

25 + 144 = hyp^2

169 = hyp^2

13 = hyp

Hope this helps! ;)
