Nathan packs 25 boxes in 2 hours. how many boxes can he pack in his 8-hour shift? 5) 13 candy bars weigh 26 ounces. what is the weight of 35 candy bars?

Step-by-step explanation:

these can be solved in a couple of wayseither by proportions or by finding the unit rate I will do one of each

25 boxes in 2 hrs = x boxes in 8 hrs

 25          x

 =      cross multiply

 2             8

(2)(x) = (8)(25)

2x = 200

x = 200/2

x = 100 <=== nathan can pack 100 boxes in 8 hrs

13 candy bars weigh 26 ozthat means each candy bar weighs 26/13 = 2 oz. So 35 candy bars would weigh : 35 * 2 = 70 oz <==

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.
