Nina [5.8K]

Answer:

The probability that a student is taking calculus given that he or she is taking statistics is = 0.26

Step-by-step explanation:

the probability that a student is taking calculus given that he or she is taking statistics.

Let C = Calculus

S = Statistics

We solve this above Question nursing the formula;

P ( C ∪ S) = P(C) + P ( S ) - P ( C ∩ S)

From the question,

P(C) = 0.10

P( S ) = 0.18

P ( C ∩ S) = 0.02

P ( C ∪ S) = ???

P ( C ∪ S) = 0.10 + 0.18 - 0.02

= 0.28 - 0.02

= 0.26

Katarina [22]

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 $10^{9}$ in scientific notation)

1000= $10^{3}$

One trillion is $(10^{3})(10^{9})=10^{12}$

The debt is: $ 10.5 x $10^{12}$

The population is scientific notation is: 308.0 x $10^{6}$

Dividing the amount of debt by the amount of population:

$\frac{(10.5)(10^{12})}{(308.0)(10^{6})}=\frac{(10.5)(10^{12-6})}{308.0}=\frac{(10.5)(10^{6})}{308.0}$

Simplifying and expressing it in standard notation:

34090.9 dollars per person

Rounding to the nearest dollar:

34091 dollars per person.

Answer:

The initial fee for the ticket is 3.5 dollars

Step-by-step explanation:

For 4 stops, the price of a ticket is 8 dollars

For 8 stops, the price of a ticket is 14 dollars.

- The number of stops increased in this case is: 8 -4 = 4 stops

When there are more 4 stops, the price of a ticket also increase from 8 to 14 dollars => the increase in price is: 14 - 8 = 6 dollars.

Similarly, for 8 stops, the price of a ticket is 14 dollars.

For 12 stops, the price of a ticket is 20 dollars.

- The number of stops increased in this case is: 12 - 8 = 4 stops

When there are more 4 stops, the price of a ticket also increase from 14 to 20 dollars => the increase in price is: 20 - 14 = 6 dollars.

So that, the price for an extra stop is constant and equal to: 6/4 = 1.5 dollars

=> The price for 3 extra stops is: 1.5 x 3 = 4.5 dollars

For 4 stops, the price of a ticket is 8 dollars

=> The initial fee for the ticket = 8 dollars - The price for 3 extra stops = 8 - 4.5 = 3.5 dollars.
