Joshua tells his friends that for there to be snow it has to be 32o F. He uses his thermometer outside and sees snow. He finds it is only is 34oF. What is his percent error? (Round to the nearest tenth)

Percentage error = -5.9%

Step-by-step explanation:

Step 1

Percentage error =Approximate Value − theoretical  Value / Theoretical value    ×  100%

or

Percentage error = Assumed number - Result number / Result number x 100

Given  Assumed number / Approximate Value=  32o F

Result number/ Theoretical value= 34o F.

Step 2---

Percentage error = (32 - 34)/ 34  x 100

= - 2/34 x 100

= - 5.88%

Joshua  was in error by - 5.88 % which when rounded to nearest tenth gives - 5.9%.

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.

there would be 162.15 calories in this cereal.
