Answer:

Camila paid less

Step-by-step explanation:

In the question, we are told:

Camila's phone had a value of 120,000 but they gave her a 30% discount.

Therefore, Camila paid:

30% × 120,000

= 30/100 × 120,000

= 36,000

Luciana had a value of 150,000 on which they applied a 40% discount

Luciana paid:

40% × 150,000

40/100 × 150,000

= 60,000

From the calculation,

Camila paid 36,000 and Luciana paid 60,000, therefore, Camila paid less.

Luba_88 [7]

Answer:

165.47≈165 Gallons of Water

Step-by-step explanation:

According To the Question,

  • Given, A child-sized swimming pool can be modeled by a cylinder. The pool has a diameter of 6 1/2 feet (or) 6.5 feet (radius is 3.25 feet) and a height of 12 inches(1 feet).

The pool is filled with water to 2/3 of its height (H= 2/3 feet) .

Volume of Cylinder = π×R²×H , now put values, we get

Volume = 3.14×3.25²×2/3

Volume = 22.122 foot³ .

And, One cubic foot equals 7.48 gallons of water

Thus, 22.122 cubic foot equals to 165.47≈165 gallons of water .

Can someone help I need this asap
balu736 [363]

Answer:

Step-by-step explanation:

Total number of students =100

Number who bought pop corn = 62

Number who bought drinks = 47

Number who bought both =38

Hence number who did not purchase anything = 100-(62+47-38)

=29

Prob that students buys a drink = 47/100 = 0.47

PROB THAT THE  student buys a drink/he purchsaed pop corn

= Number for both/number of pop corn

=38/62 =0.613

P(buying pop corn) = 0.62 and P(drink) = 0.47

Product of these = 0.62*0.37=0.2356

Thus we find product is not equal to Prob of purchsing both

Hence cannot be independent
