Answer:

275 miles in 5 hours

55 miles in one hour

Check

to check if im right

275×2 would be how many miles she drove in 10 hours rght ? 275×2=550

550 miles in 10 hours

we know one hour is 55 miles & 5 hours is 275 & 10 hours is 550

10 hours plus 3 hours = 13 hours right ?

55 ×3 = 165

550 +165=715

715 miles in 13 hours

Step-by-step explanation:

715÷13 to get how many miles she drove in one hour .

=55 miles in 1 hour .

then multiply 55 ×5 to get how many miles she drove in 5 hours

55×5=275

275 miles in 5 hours

Orders for a computer are summarized by the optional features that are requested. The proportion of orders with no optional feat
kap26 [50]

Answer: 0.28

Step-by-step explanation:

Let´s name the proportion of orders

  • with no optional features: "N"
  • with one optional feature: "O"
  • and the proportion of orders with more than one optional feature: "M"

<em>The sum of all of these proportions is equal to the total quantity of orders.</em>

Therefore,

N + O + M = 1

Then, substracting N and O on each side of that equation,

the proportion of orders with more than one optional feature (M) is:

M = 1 - N - O

M = 1 - 0.38 - 0,34

M = 0.28
