A Sample Of 100 Clients Of An Exercise Facility Was Selected. Let X- The Number Of Days Per Week That A Randomly Selected Client
julia-pushkina [17]

Answer: 1.013

Step-by-step explanation:

Given the following data :

X_______f___fx___fx²

1_______15__15___15

2______30__60__120

3______28__84__252

4______10__40___160

______ 83__199__547

Number that is 1.5 standard deviations below the mean :

Mean(m) :

Σfx /Σf

(15 + 30 + 28 + 10) / 83

= 199 / 83

= 2.3976

Standard deviation(s) :

Sqrt[(Σfx² - (Σfx)²/Σf) /Σf-1]

sqrt[(547 - (199)²/83) / 83 - 1]

sqrt[(547 - (39601/83) / 82]

sqrt[(547 - 477.12) / 82]

sqrt(0.8522)

Standard deviation = 0.9231

1.5 standard deviations below the mean:

Mean - 1.5(standard deviation)

2.3976 - 1.5(0.9231)

2.3976 -1.38465

= 1.01295

= 1.013

an artist enlarged a drawing she made. the original is 3cm wide and 5cm tall .the artist set the copier zoom button to 120% . wh
gizmo_the_mogwai [7]

For this case we have the following data:

The original dimensions of the drawing are:

  • Width: 3cm
  • Height: 5cm

If the copier zoom is at 120%, we can find the new dimensions of the drawing by making a rule of three:

Width:

3 ----------> 100%

x ----------> 120%

Where x represents the new width of the drawing:

x=\frac{(120*3)}{100}\\x=3.6cm

Long:

5 ----------> 100%

y ----------> 120%

Where y represents the new long of the drawing:

y=\frac{(120*5)}{100}\\y=6cm

Thus, the new dimensions are 3.6 cm wide and 6 cm long

Answer:

the longer dimension of the new drawing is 6cm
