Ajar of peanut butter contains 442 g with a standard deviation of 10.2 g find the probability that a jar contains less than 436 g assume a normal distribution

7/34

Explanation:

442 subtract 10.2 is 431.8

436 subtract 431.8 is 4.2.

10.2 times two is 20.4.

4.2 out of 20.4 is 4.2/20.4

4.2/20.4 equals 7/34

step-by-step explanation:

good luck

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
