Quinn needs to buy fabric for a border to sew onto all four edges of a tablecloth. he also needs an extra 0.875 feet of fabric to make a matching potholder. the length of the table cloth is 4/3 of its width (w) in feet. the total amount of fabric needed (f), in feet, is represented by the equation below.
f=2 (w+4/3 w) + 0.875
quinn needs 113/8 feet of fabric for the border of the tablecloth and the potholder. what is the width of quinn's tablecloth?

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.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
