Answer:
The unknown information is how many months she will use her phone, and how many GB she will download. We can represent these with literally any non-number symbol, letters, greek letters (if ur cool), but to simplify it we can represent the number of months with 'm' and the number gigabytes with 'g'
21m + 3g ≤ 30
Step-by-step explanation:
Answer:
- <em>m</em> =
- <em>μ</em> = 20
- <em>σ </em>= 20
The probability that a person is willing to commute more than 25 miles is 0.2865.
Step-by-step explanation:
Exponential probability distribution is used to define the probability distribution of the amount of time until some specific event takes place.
A random variable <em>X</em> follows an exponential distribution with parameter <em>m</em>.
The decay parameter is, <em>m</em>.
The probability distribution function of an Exponential distribution is:

<u>Given</u>: The decay parameter is, 
<em>X</em> is defined as the distance people are willing to commute in miles.
- The decay parameter is <em>m</em> =
. - The mean of the distribution is:
. - The standard deviation is:
Compute the probability that a person is willing to commute more than 25 miles as follows:

Thus, the probability that a person is willing to commute more than 25 miles is 0.2865.
The only difference between the 2 is that the volume for cuboid with full unit cubes = l x w x h and half units cube if 1/2 x l x w x h
Answer:
Probability of missing two passes in a row is 0.08.
Step-by-step explanation:
Event E = A football player misses twice in a row.
P(E) = ?
Event X = Football player misses the first pass
P(X) = 0.4
Event Y = Football player misses just after he first miss
P(Y) = 0.2
Both the events are exclusive so the probability of occuring of these two events can be calculated by the formula:
P(E) = P(X).P(Y)
P(E) = 0.4*0.2
P(E) = 0.08
Answer:
Step-by-step explanation:
function 1 : y = 4x + 5
In y = mx + b form, which is what ur equation is in, the slope can be found in the m position. So the slope of this function is 4.
function 2 : (1,6),(3,10)
slope = (y2 - y1) / (x2 - x1)
(1,6)...x1 = 1 and y1 = 6
(3,10)...x2 = 3 and y2 = 10
now we sub
slope = (10 - 6) / (3 - 1) = 4/2 = 2
B. Function 1, because the slope is 4 and the slope of function 2 is 2. <==
