A variable is normally distributed with mean 18 and standard deviation 3.
(a) Determine the quartiles of the variable
b)obtain and interpret the 85th percentile
C) Find the value that 65% of all possible
values of the variable exceed
d) Find the two values that divide the area
under the corresponding normal curve into a
middle area of 0.95 and two outside areas of
0.025. Interpret the answer

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

step-by-step explanation:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
