The number of beads on 500 necklaces follow normal distribution whose mean is 24 beads and standard deviation os 4 beads. how many necklaces have more than 28 beads?

 The numbers of beads on 500 handcrafted bead necklaces follow a normal distribution whose mean is 24 beads and standard deviation is 4 beads. 

so

About 24 necklaces have more than 28 beads. 

About 48 necklaces have more than 28 beads. 

About 80 necklaces have more than 28 beads. 

About 96 necklaces have more than 28 beads

 About 80 necklaces have more than 28 beads. 

Step-by-step explanation:

About 80 necklaces have more than 28 beads. 

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
