First we will go to the section that lists that students that like hotdogs.  76 students out of 150 like hotdogs.  Out of those 76 students, which of them like burgers?  
32 students like hotdogs and burgers.  32/76 is equal to .421..., which when multiplied by 100 is equal to approximately 42.1%.  We found the conditional frequency, or the column frequency.  The correct answer is C.

2 years ago, father age was nine times the son age but 3 years later it will be 5 times only. find the present ages of the fathe
Goshia [24]

Answer:

<u><em>The Father is currently 47 and the Son is 7</em></u>

Step-by-step explanation:

Let F and S be the present ages of Father and Son, respectively.

We are told that <u>(F-2) = 9(S-2)</u> [2 years ago, father age was nine times the son age]

We also learn that <u>(F+3) = 5(S+3)</u>  [3 years later it will be 5 times only]

Take the first expression and isolate one of the variables (S or F).  I'll isolate F:

(F-2) = 9(S-2)

F = 9S - 16

Now use this in the second expression:

(F+3) = 5(S+3)

((9S-16)+3) = 5(S+3)

9S-13 = 5S+15

4S = 28

S = 7

Since F = 9S-16,

F = 9*(7)-16

F = 47

<u><em>Father is 47 and Son is 7</em></u>

CHECK:

Was the father 9 times the age of his son 2 years ago?

Father would have been 45 and son 5.  Yes, 9*5 = 45

In 3 years will he be 5 times older than his son?  Yes, Father would be 50 and son would be 10.  5*(10) = 50

Why is the percent not the same as the percent you find from he percent of money
nexus9112 [7]
Percentage is a way to express a relation between two numbers as a fraction of 100<span>. In other words, the percentage tells us how one number relates to another. If we know that number A is </span>25%<span> of number </span>B<span>, we know that </span>A<span> to </span>B<span> is like </span>25<span> is to </span>100<span> (one more transformation: </span>A<span> is four times smaller than </span>B<span>). This is Percentage Calculator's lesson on what is percentage. 
  But in money a percent is how many cents past the dollar the number is.</span>
