zaharov [31]

Answer:

7t^2 + 21t

Step-by-step explanation:

You have 7 tiles of each t by t+3.

One tile has an area of

t * (t+3) = t^2 + 3t

So in total the area is

7* (t^2 + 3t)

7t^2 + 21t

qwelly [4]

The mean square for error in the ANOVA provides an estimate of the variance of an individual treatment average.

What is a variance?

Variance is the anticipated squared variation of a random variable from its population mean or sample mean in probability theory and statistics. Variance serves as a proxy for dispersion, or the degree to which a set of numbers deviates from their mean.

Here, We have

The mean square for error in the ANOVA provides an estimate

ANOVA = Analysis of VarianceThe correct answer is (B)

The mean square for error (MSE) in the analysis of variance (ANOVA) provides an estimate of the variance of an individual treatment average.

Unlike option C which refers to an individual observation,

option B refers to a group of observations that are classified into a single treatment sample.

The MSE measures (gives an estimate of) the variation within this treatment sample. In this case, the variation is in the average or the mean. This could be average texture, average strength, average penetration, etc.

Hence, the mean square for error in the ANOVA provides an estimate of the variance of an individual treatment average.

Jerry's CD player can hold five compact disks on a rotating tray around point A. The CD tray can move only counterclockwise. Ans

hjlf

Answer:

(a) 72 degrees

(b) 216 degrees

Let em know if you don't get how I answered either.

Step-by-step explanation:

So, to go all the way around is 360 degrees since there are 360 degrees. that means it turns 5 times for the beginning cd to be at the start again. So in 5 equal turns it goes 360 degrees. We want to know how much 360 is divided into 5 groups, or 360/5 = 72.

You can think of it this way, if it turns 72 degrees five times, it will have gone a full 360. that answers a though, each switch to another CD is 72 degrees.

b is asking how many degrees is it to go from 1 to 4. so how many movements is that? 1 to 2, 2 to 3 then 3 to 4. So 4. could have done 4-1 of course. anyway. 3 movements each 72 degrees is 72*3 = 216.
