The number of camera phones shipped globally can be modeled by the function y=1.28e^1.31x where x is the number of years since 1
erik [133]
The first thing you should know for this case is how many years there are from 1997 to 2014.
 The number of years is:
 x = 2014-1997 = 17
 Then, you must replace this value in the given equation:
 y = 1.28e ^ 1.31x
 y = 1.28 * e ^ (1.31 * (17))
 y = 6011018736
 answer:
 the number of camera phones shipped in millions in 2014 is
 y = 6011018736

In a statistics mid-term exam graded out of 100 points, the distribution of the exam scores was bi-modal with a mean of 70 point
Mnenie [13.5K]

Answer:

Step-by-step explanation:

Assuming a normal distribution for the distribution of the points scored by students in the exam, the formula for normal distribution is expressed as

z = (x - u)/s

Where

x = points scored by students

u = mean score

s = standard deviation

From the information given,

u = 70 points

s = 10.

We want to find the probability of students scored between 40 points and 100 points. It is expressed as

P(40 lesser than x lesser than or equal to 100)

For x = 40,

z = (40 - 70)/10 =-3.0

Looking at the normal distribution table, the corresponding z score is 0.0135

For x = 100,

z = (100 - 70)/10 =3.0

Looking at the normal distribution table, the corresponding z score is 0.99865

P(40 lesser than x lesser than or equal to 100) = 0.99865 - 0.0135 = 0.98515

The percentage of students scored between 40 points and 100 points will be 0.986 × 100 = 98.4%
