Question

if 400 people are surveyed, what percentage of the people surveyed selected tennis as their favorite sport?
favorite sport | no. of people
tennis |
sailing | 96
walking | 20
netball | 216
favorite sport is tennis = %

Explanation:

Step1: Find the number of people who like tennis

First, we know the total number of people surveyed is 400. The number of people who like sailing is 96, walking is 20, and netball is 216. So we calculate the number of people who like tennis by subtracting the sum of the other groups from the total.
Sum of other groups: \(96 + 20 + 216 = 332\)
Number of tennis lovers: \(400 - 332 = 68\) (Wait, no, wait, maybe I misread the table. Wait, the table has Tennis with no number, Sailing 96, Walking 20, Netball 216. Wait, total is 400, so Tennis number is \(400-(96 + 20 + 216)=400 - 332 = 68\)? Wait, no, maybe the table is misformatted. Wait, maybe the first row is Tennis, and the numbers are: Tennis (let's say x), Sailing 96, Walking 20, Netball 216. So \(x + 96 + 20 + 216 = 400\), so \(x = 400 - 96 - 20 - 216 = 400 - 332 = 68\). Wait, but maybe I made a mistake. Wait, let's check again. 96 + 20 is 116, 116 + 216 is 332. 400 - 332 is 68. So number of tennis lovers is 68.

Step2: Calculate the percentage

Percentage formula is \(\frac{\text{Number of tennis lovers}}{\text{Total number of people}} \times 100\%\)
So \(\frac{68}{400} \times 100\% = 17\%\) (Wait, no, 68 divided by 400: 68/400 = 0.17, times 100 is 17. Wait, but maybe I misread the table. Wait, maybe the numbers are: Tennis (let's see, maybe the table is: Favorite Sport | No. of people, with Tennis, Sailing 96, Walking 20, Netball 216. So total is 400, so Tennis is 400 - 96 -20 -216 = 68. Then percentage is (68/400)*100 = 17%. Wait, but maybe I made a mistake. Wait, 96 +20 is 116, 116 +216 is 332, 400 -332 is 68. Then 68/400 = 0.17, so 17%.

Wait, but maybe the table was supposed to have Tennis as, say, maybe I misread the numbers. Wait, maybe the original table has Tennis with 68? Wait, no, let's check again. Wait, the user's table: "Favorite Sport | No. of people; Tennis; Sailing 96; Walking 20; Netball 216". So the first row is Tennis, no number, then Sailing 96, Walking 20, Netball 216. So total is 400, so Tennis is 400 - 96 -20 -216 = 68. Then percentage is (68/400)*100 = 17%.

Wait, but maybe I made a mistake in the number of tennis lovers. Let's recalculate:

Total = 400

Sailing: 96

Walking: 20

Netball: 216

Sum of Sailing + Walking + Netball = 96 + 20 + 216 = 332

Tennis = 400 - 332 = 68

Percentage = (68 / 400) * 100 = 17%

Yes, that's correct.

Answer:

17%
