In a class of 20 students, on average, 4 will be left-handed. if a class includes 14 "lefties", estimate how many students are in the class.

  70

Step-by-step explanation:

The number in the class is 20/4 = 5 times the number of "lefties."

  5 · 14 = 70

The class is estimated to have 70 students.

For this case, we must indicate how many students there are in the class knowing that it includes 14 "lefties". For this, we make a rule of three:

20 -------------> 4

x ---------------> 14

Where the variable "x" the number of students in the class.

Thus, if the class includes 14 left-handers, then according to the base average, the class will have a total of 70 students.

70 students

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.
