(2,2), 24 units squared
Step-by-step explanation:
D is at (2,2) because it would make Line AD equal to line BC and line AB equal to line CD, which would make a rectangle.
Area= length x width
A= 6 x 4
A=24 units squared
Good Luck!
Answer:
The probability that a call last between 4.2 and 4.9 minutes is 0.4599
Step-by-step explanation:
Let X be the length in minutes of a random phone call. X is a normal distribution with mean λ=4.2 and standard deviation σ=0.4. We want to know P(4.2 < X < 4.9). In order to make computations, we will use W, the standarization of X, given by the following formula

We will use
, the cummulative distribution function of W. The values of
are well known and the can be found in the attached file

We conclude that the probability that a call last between 4.2 and 4.9 minutes is 0.4599
