Yes

The definition Khan Academy gave is "A statistical question is one that can be answered by collecting data and where there will be variability in that data. For example, there will likely be variability in the data collected to answer the question, "How much do the animals at Fancy Farm weigh?" but not to answer, "What color hat is Sara wearing?".

A-C all don't have variability. They are set in place. However, the ages of all people in your class can change annd thus exhibit variability.

Complete Question

A sensor output was acquired for 32 seconds at a rate of 200 Hz and spectral analysis was performed using FFT. If the data set was split into 5 segments (each 6.4 seconds long), what is the resulting:

a)F minimum

b) F maximum

c) Frequency resolution

Answer:

a) $Fmax=100Hz$

b) $Fmin=0Hz$

c) $F_r=0.0313$

Step-by-step explanation:

From the question we are told that:

Time $t=32sec$

Frequency $F=200Hz$

Segments $\mu=5$

Generally the equation for Frequency Range is mathematically given by

$Fmax=\frac{F}{2}$

$Fmax=100Hz$

Therefore

a) $Fmax=100Hz$

b) $Fmin=0Hz$

Generally the equation for Frequency Resolution is mathematically given by

$F_r=\frac{F}{N}$

Where

N=The Total dat points

N=Sampling Frequency *Time

$N=200*32$

$N=6400$

Therefore

$F_r=\frac{200}{6400}$

$F_r=0.0313$

Please help i dont understand :(

Answer:306

Step-by-step explanation:

since the width of the bottom square is 10, you split it between the triangles on top. You have to do this because 7 is not the whole width of the two triangles. So then the width of the triangles would be 12, 12 times 9 is 108, you'd have 216 total for both triangles and then the area of the square is 90, 90 plus 216 is 306.

Need help with this.

Step-by-step explanation:

put some x values into the equation

i.e : -2, -1, 0 ,1 ,2

3/5 (-2) +2 = 4/5 (-2, 4/5)

3/5 (-1) +2 = 7/5 (-1, 7/5)

3/5 (0) +2 = 2 (0, 2)

3/5 (1) +2 = 2.6 (1, 2.6)

3/5 (2) +2= 3.2 (2, 3.2)

Then plot these on the graph as corodinates with the x values
