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?

Describe how you could draw a diagram for a problem about finding the total length for two strings, 15 inches long and 7 inches
Varvara68 [4.7K]
Two strings are 15 inches and 7 inches long.

You could draw a diagram that has two rulers (that are longer than 12 inches).

Draw a piece of string that is exactly 15 inches on one ruler.
Draw another piece of string on the other ruler at exactly 7 inches.

Then you can find the total length of the two strings by adding 15 and 7 inches.
15 + 7 = 22

The total length of both the strings is 22 inches. You can draw a ruler and a piece of string on it at 22 inches.

kondaur [170]

Answer:

B

Step-by-step explanation:

The probability of obtaining a 3 is

P(3) = \frac{1}{6}

Then after 30 spins the predicted number of times it should land on 3 is

30 × \frac{1}{6} = 5

The height of a rocket a given number of seconds after it is released is modeled by h (t) = negative 16 t squared + 32 t + 10. W
vaieri [72.5K]

Answer:The number of seconds after rocket is released

Step-by-step explanation:

Given

The height of  a rocket after it is released is modeled by

h\left ( t\right )=-16t^2+32t+10

Here t represent the number of seconds after the rocket is released.

Initial velocity can also be determined by this equation by differentiating the h\left ( t\right ) w.r.t time

\frac{\mathrm{d}h(t)}{\mathrm{d} t}=-32t+32

at t=o

\frac{\mathrm{d}h(t)}{\mathrm{d} t}=32

thus initial velocity will be 32 units/s
