18A person typically breathes about 8.64 x 10^3 liters of air per day. The life expectancy of
a person in the United States at birth is about 29,200 days. Estimate the total amount of
air a person born in the United States breathes over a lifetime.

Answer:

the answer would be 8

Step-by-step explanation:

To find the percentage of people with an IQ score between 83 and 117, we need to find the area under the bell-shaped curve between these two scores.

First, we need to standardize the scores by subtracting the mean from each score and dividing by the standard deviation.

For a score of 83:

Standardized score = (83 - 100) / 17 = -1

For a score of 117:Standardized score = (117 - 100) / 17 = 1

Now, we can find the area under the curve between these standardized scores using a standard normal distribution table or calculator.

Using a standard normal distribution table, we can find the area for a standardized score of -1 as 0.1587. This represents the percentage of people below a score of 83.

Similarly, the area for a standardized score of 1 is 0.8413, representing the percentage of people below a score of 117.

To find the area between these two scores, we subtract the area below 83 from the area below 117:

0.8413 - 0.1587 = 0.6826

So approximately 68.26% of people have an IQ score between 83 and 117.

Answer:

x=30

Step-by-step explanation:

2 times 1/2(x+6)=18 times 2

x+6=36

x+6-6=36-6

x=30

whomever is reporting me please stop(echo2155)

Answer:

Step-by-step explanation:

First you have to perform distributive property which is

2((x+6)=18) 2

Which will turn to

X+6=36

Then move the constant to the right so

X=36-6 then calculate

So the answer is 30

The value of x is 30
