Marrrta [24]

250/974 = x/40,000...250 opposed to 974 total = x opposed to 40,000 total
cross multiply because this is a proportion
974x = 10,000,000
x = 10,000,000/974
x = 10266.94 rounds to 10,267 <==

stiks02 [169]

Answer: Park P

Step-by-step explanation:

Since, According to the question,

Number of yellow bird in park P = 33

Total number of the bird in park P = 53

Thus, the percentage of yellow bird in park P = $\frac{33}{53} \times 100$ = 62.264150943% ≈ 62 %

Number of yellow bird in park Q = 20

Total number of the bird in park Q = 48

Thus, the percentage of yellow bird in park P = $\frac{20}{48} \times 100$ =41.666666666% ≈ 42%

Number of yellow bird in park R = 54

Total number of the bird in park R = 90

Thus, the percentage of yellow bird in park R = $\frac{54}{90} \times 100$ = 60 %

Number of yellow bird in park S = 44

Total number of the bird in park S = 83

Thus, the percentage of yellow bird in park P = $\frac{44}{83} \times 100$ =53.012048192 % ≈ 53 %

Since, 62% > 60% > 53% > 42%

Therefore, highest percentage of the yellow bird is 62 %

Which is present in park P.

The boss is correct because if you press the button 5 time knowing that if u press it one time it is going to have the photo at 7.04 inches so if you keep going by the time you get to 5 times it is going to about 4.22 so you would have had to press it 4 times which would equal 5.4 inches
