What conclusions can you draw by comparing the mean and MAD repairs per vehicle for each type of Vehicle

1 answer:

5 0

The mean would tell you the average number of repairs per vehicle type. It is the total amount of repairs divided by the total number of vehicles.

The mean absolute deviation (MAD) describes how close the values are typically to the mean. It is an average of the distances the individual points are from the mean. Basically, it tells how spread out the data is.

For all values of x<br> f(x) = 3x + 2<br> Find f-¹(-12)

Novosadov [1.4K]

Answer:

-4.67

Step-by-step explanation:

first find f^-1(x)

let f(x)=y

y=3x+2

3x=y-2

x=y-2/3

Therefore f^-1(x)=x-2/3

Now f^-1(-12)=-12-2/3

=-14/3

=-4.67

The formula for wind chill C (in degrees Fahrenheit) is given by C = 35.74 + 0.6215T - 35.75v^0.16 + 0.4275Tv^0.16 where v is th

Diano4ka-milaya [45]

Answer:

dC = 2.44

Relative error = 19%

Step-by-step explanation:

$C = 35.74 + 0.6215*T - 35.75*v^(0.16) + 0.4275*T*v^(0.16)$

Δv = 3 ; ΔT = 1 , v = 23, T = 8

Use differential Calculus

$dC = Cv.dv + Ct.dt$

$Cv = dC/dv = -5.72*v^(-0.84) + 0.0684*T*v^(-0.84)\\Ct = dC/dT = 0.6215 + 0.4275*v^(0.16)\\dC = modulus (Cv.dv) + modulus (CT.dT)\\dC = (-5.72*v^(-0.84) + 0.0684*T*v^(-0.84))* 3 + (0.6215 + 0.4275*v^(0.16))*1\\dC = 2.44$

Relative Error

dC / C @(T = 8, v=23) * 100 = 19 %

Which expression is equivalent to 2.2 − 0.5(0.6x − 1.8) ?

yawa3891 [41]

Answer:

D is equivalent to the expression.

Step-by-step explanation:

The expression that is given equals 2.8, or 2.8x.

A. This expression equals 1.6x, and 1.6x is not equivalent to 2.8x

B. 0.3x + 3.1 = 3.4x. This doesn't have the answer of 2.8x.

C. 1.3 - 0.3x = 1 or x.

D. 3.1 - 0.3x = 2.8x. D is the answer.
