To do this you need to do 4300 x 1.04 to the power of 3
Answer:
3
Step-by-step explanation:
V=⅓b²h
16=⅓*16*h
16=16h/3
h=3cm
2 because there at more than just 4-2 but the awnser is 2
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
