Approximately what percentage of apple diameters is greater than the 66th percentile? 21. A. 3.4% B. 17% C. 66% D. 34%
astraxan [27]

Answer:

The correct option is D) 34%.

Step-by-step explanation:

Consider the provided information.

If it is given that you scored in the 66th percentile, that means you scored "as well as or better than" 66% of the group.

Here it is given that 66th percentile that means 66% of the data located below the 66th percentile.

That means 100%-66% = 34% of the data located above the 66th percentile,

Thus, the approximately 34% percentage of apple diameters is greater than the 66th percentile.

Therefore, the correct option is D) 34%.

Original price of a hotel: $240.00 per night.
lawyer [7]

Answer:

$ 929

Step-by-step explanation:

Given: Original price of stay in hotel= $240 per night

           Discount= 25%

           Total taxes and fee = 29%

Now, finding the price of stay for four night.

Using unitary method to solve:

As we know original price of hotel stay per night is $240

∴ Price of four night stay at original price is 240\times 4 = \$ 960

Next, 25% discount given on the price of four night stay.

∴ 960 - \frac{25}{100} \times 960 = 960 - 240

= \$ 720

∴Price of four night hotel stay after discount is \$ 720

Now, 29% taxes and fees been added to the price.

Price of hotel stay after discount + Taxes paid.

720 + ( \frac{29}{100} \times 720) = 720 + 209

= \$ 929

∴ \$ 929 is the price to be paid for four night stay at hotel after discount and taxes.
