Hey There!

To find the height of the building there is only one way I can think of to find the answer;

Figure out the % 2.5 is out of 4 and apply that to 20...

2.5 is 62.5% of 4 and the tree is four meters tall.

20 is 62.5% of 32, so the building could be 32 meters tall

Hope I helped, Brainliest & Five stars is always appreciated.

Due to a packaging error, 4 cans labeled diet soda were accidentally filled with regular soda and placed in a 12 pack carton of
Sophie [7]

Answer:

Probability that both cans were regular soda =  \frac{1}{11}

Step-by-step explanation:

Probability = \frac{Desired outcome}{Total possible outcomes}

We are given 12 total number of cans; 4 cans have been accidentally filled with diet soda.

Probability that first can is a regular soda:

Outcome that first can is a regular soda will give us the number of regular soda available which are 4

Using formula of probability

Total possible outcomes are, n(total) = 12

Desired outcome: 4 (cans of regular soda)

P(1st can) =  \frac{4}{12} = \frac{1}{3}

Probability that 2nd can is a regular soda:

<em>As we have already taken a can of regular soda from the pack, the total soda in the pack now 11 and the regular soda left are 3.</em>

Total possible outcomes are, n(total) = 11

Desired outcome: 3 (cans of regular soda as one has already been taken)

P(2nd can) =  \frac{3}{11}


Probability that both cans are regular soda:

P(both) = P(1st can) × P(2nd can)

             = \frac{1}{3} * \frac{3}{11}

             = \frac{1}{11}

Kingbird, Inc. purchased merchandise with an invoice price of $3200 and credit terms of 2/9, n/30. Assuming a 360-day year, what
Tatiana [17]

Answer:

80%

Step-by-step explanation:

Data provided as per the question

Number of days in a year = 360 days

Discount provided = 2%

Total net credit period = 30

The calculation of implied annual interest rate inherent in the credit terms is shown below :-

Inherent\ in\ the\ credit\ terms\ = \frac{Number\ of\ days\ in\ a\ year}{Total\ net\ credit\ period\ - Remaining\ days}\times 2\%

Inherent\ in\ the\ credit\ terms\ = \frac{360}{30 - (30\ -\ 9)}\times 2\%Inherent\ in\ the\ credit\ terms\ = \frac{360}{30 - 21}\times 2\%

Inherent\ in\ the\ credit\ terms\ = \frac{360}{\ 9}\times 2\%

Inherent\ in\ the\ credit\ terms\ = \ 40\times 2\%

Inherent\ in\ the\ credit\ terms\ = \ 80\%

Therefore for computing the inherent in the credit terms we simply applied the above formula.
