Answer:

j/j+80 and 36/k+36

Step-by-step explanation:

The table is shown in the picture attached.

The way feedback was submitted had an impact on whether or not feedback was positive is comparing through the following values: j/j+80 and 36/k+36

j/j+80 represents the weight of positive emailed responses respect all emailed responses and 36/k+36 represents the weight of positive phoned responses respect all phoned responses

A new curved screen TV costs $3,508.80. A family makes a down payment of $450 and pays off the balance in 24 equal monthly payme

77julia77 [94]

Answer:

$127.45

Step-by-step explanation:

First, subtract 450 from 3,508.80:

3,508.80 - 450 = 3058.8

Then, divide this by 24 to find the monthly payment:

3058.8/24

= 127.45

So, the monthly payment was $127.45

As shown in the question, the translation changes the points as follows:

$(x,y)\rightarrow(x+2,y-2)$

Therefore:

$\begin{gathered} C(-5,-1)\rightarrow C^{\prime}(-3,-3) \\ D(-4,3)\rightarrow D^{\prime}(-2,1) \\ E(-3,2)\rightarrow E^{\prime}(-1,0) \\ F(-2,0)\rightarrow F^{\prime}(0,-2) \end{gathered}$

A population of scores has µ = 50 and σ = 5. If every score in the population is multiplied by 3, then what are the new values

PilotLPTM [1.2K]

Answer:

The new mean = 3 × (the old mean) = 150

The new standard deviation is also = 3 × (The old standard deviation) = 15

Step-by-step explanation:

µ = 50 and σ = 5

The mean is the sum of variables divided by the number of variables.

Mean = (Σx)/N = µ = 50

x = each variable

N = number of variables

If each variable changed to 3x

Mean becomes

Mean = (Σ(3x))/N = 3 (Σx)/N = 3 × µ = 3 × 50 = 150.

The standard deviation is the square root of variance. And variance is an average of the squared deviations from the mean.

The standard deviation measures the rate of spread of the data set around the mean.

Standard deviation = σ = √[Σ(x - µ)²/N]

x = each variable

µ = mean

N = number of variables

If each variable changed to 3x

Recall µ changed to 3µ

Standard deviation = σ = √[Σ(3x - 3µ)²/N]

σ = √[Σ 3² (x - µ)²/N] = √[(3²)Σ(x - µ)²/N] = 3×√[Σ(x - µ)²/N] = 3 × σ = 3 × 5 = 15

If every score is multiplied by 3, it is logical to reason that the average of the new set of numbers also is 3× the old average.

And the new set of numbers spread out similarly around this new mean, only that the new space of spread is now 3× the old one.
