An empty shipping box weighs 250 grams. The box is then filled with T-shirts. Each T-shirt weighs 132.5 grams. The equation W = 250 + 132.5T represents the relationship between the quantities in this situation, where W is the weight, in grams, of the filled box and T the number of shirts in the box. Select two possible solutions to the equation W = 250 + 132.5T .

For 20  t shirts  the weight is 2900 grams

and for 25 t- shirts the weight is 3562.5 gms  

Step-by-step explanation:

W = 250 + 132.5T

1) If we know the total weight we can find the number of t- shirts and

2) if the number of shirts are known the total weight can be calculated.

For example if the expression W= 250 + 132.5T is written like is written like

2900 = 250 + 132.5T

2900-250 = 132.5T

T = 2650/132.5= 20 shirts

Similarly if we have 25 t- shirts then the weight would be

W = 250 + 132.5(25)

W= 250+ 3312.5=  3562.5 gms  

step-by-step explanation:

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.
