Add the total bills:
23.59 + 40.65 + 30.50 + 15.68 = 110.42
Divide his tips by the total bills to get the rate of the tips
17.67 ÷ 110.42 = 0.16
0.16 x 100% = 16%
His tips were 16% of the bills.
To check:
23.59 x 16% = 3.7744
40.65 x 16% = 6.504
30.50 x 16% = 4.88
15.68 x 16% = <u>2.5088</u>
total tips 17.6672 rounded off to 17.67
Answer:
To three decimal place = 0.030
Step-by-step explanation:
Let probability of death in white p (WH) = 86%
Let probability of death in black p(B) =12%
Let probability of death in Asian p(A) = 2%
Probability of death caused by diabetes among white will be 2.8% of p (WH) = 0.86 x 0.028 = 0.02408
Probability of death caused by diabetes among black will be 4.4% of p (B) = 0.12 x 0.044 = 0.00528
Probability of death caused by diabetes among Asian will be 3.5% of p (A) = 0.02x 0.035 = 0.0007
If a sample is chosen and the cause is diabetes then the probability will be
Probability of death caused by diabetes among white or Probability of death caused by diabetes among black or Probability of death caused by diabetes among Asian
0.02408 +0.00528 +0.0007 = 0.03006
To three decimal place = 0.030
Answer:
67-32=a
if his mom is 67 and he is 32 years younger 67 minus 32 would equal a which is his age
The answer would be 25.65
