Answer:7+9=16

Step-by-step explanation:

if they were the on the same quadrant, it would be 2, but since y is a positive and a negative, you have to count the distance from each point to the x axis, then add them

Identify the error or errors in this argument that supposedly shows that if ∃xp (x) ∧ ∃xq(x) is true then ∃x(p (x) ∧ q(x)) is tr
Ymorist [56]

The mistake lies in steps 3 and 5.

In fact, you know that there exists some element that satisfies p(x), and some element that satisfies q(x), but you can't assume that the same element satisfies p(x) and q(x) at the same time.

So, you are only allowed to say

p(c) existential instantiation from (2)

q(d) existential instantiation from (4)

and so you can't do the conjunction in step 6 anymore.


Here's an example: if you follow this logic, you would say something like:

"There exists a person who is born in Italy and there exists a person who is born in the USA. Therefore, there exists a person who is born in both Italy and the USA"

which is clearly false: altought there exists a person for each proposition, they are not the same person.


This is even easier if q is the negation of p:

"There exists a number greater than 10, and there exists a number lesser than 10. Therefore, there exists a number that is greater than and lesser than 10 at the same time"

which is clearly absurd

One measure of general health is your body mass index (BMI). Adults with a BMI between 18.5 and 24.9 are generally considered to
soldi70 [24.7K]

Answer: 0.1797

Step-by-step explanation:

Given : \mu=24.5\ \ ; \sigma=1.2

Let x be the random variable that represents BMI for adults in this country.

We assume that  BMI for adults in this country is normally distributed.

Then, z-score for x=25.6 ,\because z=\dfrac{x-\mu}{\sigma}

\Rightarrow\ z=\dfrac{25.6-24.5}{1.2}\approx0.9167

Using z-value table , we have

The probability that the person's BMI is more than 25.6 :

P(x>25.6)=P(z>0.9167)=1-P(z\leq0.9167)\\\\=1- 0.8203413=0.1796587\approx0.1797

Hence, the probability that the person's BMI is more than 25.6 = 0.1797

Hence, the probability that the person's BMI is more than 25.6 = 0.1796

Hence, the  probability of the stick's weight being 2.23 oz or greater = 0.0174
