Answer:

Mean : 47.48

Median : 46

Mode : 46

Step-by-step explanation:

1) Mean= Total sum / Total Entries

Sum = 41*3 +42*2+43*4+45*3+46*7+49*2+50*1+51*2+53*1+54*1+55*2+56*2+57*1

Sum = 123+84+172+135+322+98+50+102+53+54+110+112+57

sum = 1472

Total Entries = 3+2+4+3+7+2+1+2+1+1+2+2+1= 31

Mean = 1472/31

= 47.48

ii) Median = 16th Value

As there are total 31 entries , Hence the Median will be the entry coming on 16th place

Median = 46

iii) Mode

The entry which is repeated for the maximum number of times is called the mode. Here 46 is repeated the most. hence 46 is the mode

Pls help I don’t get it

Well you are trying to find x, so you would divide 5/8 by itself and on the other side.

(5/8x / 5/8) = (10 / 5/8)

x=16

Hope this helps!

Solve 0 = (x – 4)2 – 1 by graphing the related function.

fomenos

Answer:

Therefore, the solutions of the quadratic equations are:

$x=5,\:x=3$

The graph is also attached.

Step-by-step explanation:

The solution of the graph could be obtained by finding the x-intercept.

$y=\left(x-\:4\right)^2-1$

Finding the x-intercept by substituting the value y = 0

$y=\left(x-\:4\right)^2-1$

$\:0\:=\:\left(x\:-\:4\right)^2\:-\:1$ ∵ y = 0

$\left(x-4\right)^2-1=0$

$\left(x-4\right)^2-1+1=0+1$

$\left(x-4\right)^2=1$

$\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$\mathrm{Solve\:}\:x-4=\sqrt{1}$

$\mathrm{Apply\:rule}\:\sqrt{1}=1$

$x-4=1$

$x=5$

$\mathrm{Solve\:}\:x-4=-\sqrt{1}$

$\mathrm{Apply\:rule}\:\sqrt{1}=1$

$x-4=-1$

$x=3$

So, when y = 0, then x values are 3, and 5.

Therefore, the solutions of the quadratic equations are:

$x=5,\:x=3$

The graph is also attached. As the graph is a Parabola. It is visible from the graph that the values of y = 0 at x = 5 and x = 3. As the graph is a Parabola.
