Answer:

Relative frequency of male nonparticipation is O.42

Step-by-step explanation:

Figure 1 is your partially filled frequency table.

1. Complete the table

(a) Total No

Total Yes + Total No = Total

     102     + Total No = 187

                   Total No = 187 - 102  

                                   = 85

 

(b) Female No

Male No  + Female  No = Total No

     40      + Female No =      85

                  Female No =       85 - 40

                                      =       45

(c) Female Yes

Female Yes + Female  No = Female Total

Female Yes +       45          =        95

Female Yes                         =        95 - 45

                                            =        50

(d) Male Yes

Male Yes + Female  Yes = Total Yes

Male Yes +         50          =     102

Male Yes                           =     102 - 50

                                          =     52

(e) Male Total

Male Yes + Male No = Male Total

     52      +       40     = Male Total

         Male Total        =       92

Figure 2 shows the completed table.

2. Frequency of Male No

There are 92 males, of whom 40 do not participate in an after-school activity.

The relative frequency of male nonparticipation is

40/92 = 0.43

The height h (in feet) of an object dropped from a ledge after x seconds can be modeled by h(x)=−16x2+36 . The object is dropped
kakasveta [241]

Check the picture below.

\bf ~~~~~~\textit{initial velocity in feet} \\\\ h(t) = -16t^2+v_ot+h_o \quad \begin{cases} v_o=\textit{initial velocity}&\\ \qquad \textit{of the object}\\ h_o=\textit{initial height}&\\ \qquad \textit{of the object}\\ h=\textit{object's height}&\\ \qquad \textit{at "t" seconds} \end{cases}

so the object hits the ground when h(x) = 0, hmmm how long did it take to hit the ground the first time anyway?

\bf h(x)=-16x^2+36\implies \stackrel{h(x)}{0}=-16x^2+36\implies 16x^2=36 \\\\\\ x^2=\cfrac{36}{16}\implies x^2 = \cfrac{9}{4}\implies x=\sqrt{\cfrac{9}{4}}\implies x=\cfrac{\sqrt{9}}{\sqrt{4}}\implies x = \cfrac{3}{2}~~\textit{seconds}

now, we know the 2nd time around it hit the ground, h(x) = 0, but it took less time, it took 0.5 or 1/2 second less, well, the first time it took 3/2, if we subtract 1/2 from it, we get 3/2 - 1/2  = 2/2 = 1, so it took only 1 second this time then, meaning x = 1.

\bf ~~~~~~\textit{initial velocity in feet} \\\\ h(x) = -16x^2+v_ox+h_o \quad \begin{cases} v_o=\textit{initial velocity}&0\\ \qquad \textit{of the object}\\ h_o=\textit{initial height}&\\ \qquad \textit{of the object}\\ h=\textit{object's height}&0\\ \qquad \textit{at "t" seconds}\\ x=\textit{seconds}&1 \end{cases} \\\\\\ 0=-16(1)^2+0x+h_o\implies 0=-16+h_o\implies 16=h_o \\\\[-0.35em] ~\dotfill\\\\ ~\hfill h(x) = -16x^2+16~\hfill

quick info:

in case you're wondering what's that pesky -16x² doing there, is gravity's pull in ft/s².
