Answer:
34091 dollars per person
Step-by-step explanation:
In order to answer the question, you have to divide the amount of debt by the amount of population to obtain the amount of dollars per person.
The debt was $10.5 trillion. A trillion is a thousand billion (1000 multiplied by a billion which is 
in scientific notation)
1000=
One trillion is 
The debt is: $ 10.5 x 
The population is scientific notation is: 308.0 x 
Dividing the amount of debt by the amount of population:
Simplifying and expressing it in standard notation:
34090.9 dollars per person
Rounding to the nearest dollar:
34091 dollars per person.
Answer: D = -8

Answer:
The probability that the maximum speed is at most 49 km/h is 0.8340.
Step-by-step explanation:
Let the random variable<em> </em><em>X</em> be defined as the maximum speed of a moped.
The random variable <em>X</em> is Normally distributed with mean, <em>μ</em> = 46.8 km/h and standard deviation, <em>σ</em> = 1.75 km/h.
To compute the probability of a Normally distributed random variable we first need to convert the raw score of the random variable to a standardized or <em>z</em>-score.
The formula to convert <em>X</em> into <em>z</em>-score is:
Compute the probability that the maximum speed is at most 49 km/h as follows:
Apply continuity correction:
P (X ≤ 49) = P (X < 49 - 0.50)
= P (X < 48.50)
*Use a <em>z</em>-table for the probability.
Thus, the probability that the maximum speed is at most 49 km/h is 0.8340.
