HELP SOMEONE PLEASE!!!!!!!!!!!!!!!!!!!
omeli [17]

Answer:

3/10

Step-by-step explanation:

The question asks for the probability of finding 4 or more, so first, you must add up all of the teenagers that have 4 or more shoes. Both the 4 and 5 categories fit, so add 20 and 10. Then, find the total number of people in the sample size. Overall, 100 teenagers are represented. Finally, put the number of people that have 4 or more shoes, 30, over the sample size, 100. This equals 30/100 which should be simplified to 3/10.

nirvana33 [79]

Answer:

Step-by-step explanation:

b + n = 192

n = 5b

b + 5b = 192

6b = 192

b = 192/6

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $13 monthly fee
Tpy6a [65]

Answer:

With 250 minutes of calls the cost of the two plans is the same

Step-by-step explanation:

We must write an equation to represent the cost of each call plan.

<u>For the first plan</u>

Monthly fee

 $ 13

Cost per minute

 $ 0.17

If we call x the number of call minutes then the equation representing the cost c for this plan is:

c = 13 + 0.17x

<u>For the second plan</u>

monthly fee

$ 23

Cost per minute

$ 0.13

If we call x the number of call minutes then the equation representing the cost c for this plan is:

c = 23 + 0.13x

To know when the cost of both plans are equal, we equate the two equations and solve for x.

13 + 0.17x = 23 + 0.13x\\\\0.17x -0.13x = 23-13\\\\0.04x = 10

x = \frac{10}{0.04}

x = 250\ minutes

With 250 minutes of calls the cost of the two plans is the same: $55.5

Find the surface area of the composite object below.
pogonyaev

Answer:

Step-by-step explanation:

area of triangular endface = ½×6×8 = 24 cm²

area of rectangular endface = 4×8 = 32 cm²

area of each endface = 24+32 = 56 cm²

area of each 3×10 face = 30 cm²

area of 3×4 face = 12 cm²

area of base = 8×3 = 24 cm²

surface area = 2×56 + 2×30 + 12 + 24 = 208 cm²
