The average price for a gallon of gasoline in the United States is $3.73 and in Russia it is $3.40 (Bloomberg Businessweek, Marc

h 5–March 11, 2012). Assume these averages are the population means in the two countries and that the probability distributions are normally distributed with a standard deviation of $.25 in the United States and a standard deviation of $.20 in Russia.
a. What is the probability that a randomly selected gas station in the United States charges less than $3.50 per gallon?
b. What percentage of the gas stations in Russia charge less than $3.50 per gallon?
c. What is the probability that a randomly selected gas station in Russia charged more than the mean price in the United States?

find two consecutive odd intergers that twice the larger is fifteen more than three times the smaller
Svetach [21]

Answer:

11, 13

Step-by-step explanation:

an odd number can be represented by 2n+1

since they are consecutive, the larger odd number will be 2n + 1 + 2

now,

2(2n+3) = 2n + 1 +15

solving this eqn, we get n = 5

so the two numbers are (2n+1) = 11 and 11+2= 13

Suppose that qequals30​, Lequals5​, and Kequals15 is a point on the production function qequals​f(L, ​K). Is it posssible for qe
Kamila [148]

Answer:

No

Step-by-step explanation:

If q=30​, L=5​, and K=15 is a point on the production function q=​f(L, ​K).

Production function is an equation that expresses the relationship between the quantities of factors of production used and the amount of product obtained under the assumption that the most efficient available methods of production are used.

The combination q=30​, L=5​, and K=16 cannot be a point because we assume production functions are efficient.
