304: total students
17: riding in car
7: number of buses

304 - 17 = 287
287 divided by 7 = 41
Answer:
The expected number of times is 4.
Step-by-step explanation:
Looking at the question, we see that this follows a geometric distribution because it is asking for the expected number of trials hat will bring about the FIRST SUCCESS. The probability of success is
Since it is a geometric distribution, we know that the expected value of a random variable X, E(X) that follows a geometric distribution is given as:
E(X) = 1/p where p is the probability of success.
Therefore, the expected number of times will be
E(X) = 1/(1/p) = 1/(1/4) = 4.
Hence, the expected number of times is 4.

Answer:
y=5x-7
Step-by-step explanation:
1. find slope
<u>-2-0</u>
1-1.4
is 5
2. find y intercept
y-0=5(x-1.4)
y=5x-7
Answer:
Step-by-step explanation: A GENERAL NOTE: VERTICAL STRETCHES AND COMPRESSIONS
Given a function a new function where is a constant, is a vertical stretch or vertical compression of the function
, then the graph will be stretched., then the graph
, then there will be combination of a vertical stretch or compression with a vertical reflection.HOW TO: GIVEN A FUNCTION, GRAPH ITS VERTICAL STRETCH.Identify the value of Multiply all range values by the graph is stretched by a factor of the graph is compressed by a factor of
, the graph is either stretched or compressed and also reflected about the
EXAMPLE: GRAPHING A VERTICAL STRETCHmodels the number of fruit flies in a population over time, and is graphed below.A scientist is comparing this population to another population, whose growth follows the same pattern, but is twice as large. Sketch a graph of this population.Graph to represent the growth of the population of fruit flies.
