Rafeal’s family dinner costs $56.25. His dad wants him to leave a 35% tip. How much money should Rafeal provide as a tip? Round your answer to the nearest hundredth.(1 point) Responses $35.00 $35.00 $1.97 $1.97 $75.94 $75.94 $19.69 $19.69
To calculate the tip, we need to multiply the cost of the dinner by the percentage of the tip.
35% of $56.25 = 0.35 * 56.25 = $19.69.
Therefore, Rafeal should provide a tip of $19.69.
A university football stadium has 81,500 seats. The stadium is at full capacity on game day. Layla believes only 79,000 seats are occupied. Find the percent error of Layla’s prediction. Round your answer to the nearest hundredth of a percent.(1 point) Responses 0.0307% 0.0307% 3.07% 3.07% −3.07% negative 3.07 percent 90.3067%
To find the percent error, we need to calculate the absolute difference between the predicted number of occupied seats (79,000) and the actual number of occupied seats (81,500), and then divide that difference by the actual number of occupied seats. Finally, multiply by 100 to convert it into a percentage.
Absolute difference: |79,000 - 81,500| = 2,500
Percent error: (2,500 / 81,500) * 100 ≈ 0.0307%
Therefore, the percent error of Layla’s prediction is approximately 0.0307%.
Aatikah plans to buy books at a book fair. She thinks she will need $30.00 to purchase the books. She only spends $19.75. Find the percent error in her prediction. Round your answer to the nearest whole number.(1 point) Responses 2% 2% 52% 52% 1% 1% 58%
To find the percent error, we need to calculate the absolute difference between the predicted amount ($30.00) and the actual amount spent ($19.75), and then divide that difference by the predicted amount. Finally, multiply by 100 to convert it into a percentage.
Absolute difference: |$30.00 - $19.75| = $10.25
Percent error: ($10.25 / $30.00) * 100 ≈ 34.17%
Since we need to round the answer to the nearest whole number, the percent error in Aatikah's prediction is approximately 34%.
thats not an answer choice. the answer choices are
A. 2%
B. 52%
C. 1%
D. 58%
Apologies for the confusion. Let's recalculate the percent error using the correct answer choices.
To find the percent error, we need to calculate the absolute difference between the predicted amount ($30.00) and the actual amount spent ($19.75), and then divide that difference by the predicted amount. Finally, multiply by 100 to convert it into a percentage.
Absolute difference: |$30.00 - $19.75| = $10.25
Percent error: ($10.25 / $30.00) * 100 ≈ 34.17%
Rounding this to the nearest whole number, the percent error in Aatikah's prediction is 34%.
