alina1380 [7]

Answer:

a) The average of compy heights is 33.5 cm

b) The 68.3 % of all compy heights are in the interval:

   (30.94,36.06)

Step-by-step explanation:

a) Meaning of the mean

The mean is a number expressing the central or typical value in a set of data.

The average of compy heights is 33.5 cm. If the select one height randomly its height will be in average 33.5 cm

b) Meaning of standard deviation

The standard deviation is a quantity expressing by how much the members of a group differ from the mean value for the group.

The 68.3 % of all compy heights are in the interval

(33.5cm - 2.56cm, 33.5cm + 2.56cm) = (30.94,36.06)

It means that the 68.3 % of all data is in the interval:

(μ - δ, μ +δ)

Where: μ is the mean

            δ is the standard deviation

monitta

The equation that represent the same salary is 55,000x+2,500x=64,000+1500x

<h3>What is Algebra?</h3>

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.

Given:

Katherine has a new job and earns salary of $55,000.  Katherine will receive a salary increase of $2,500 per year .

max has a new job and earns a salary of $64,000. Max will receive a salary increase of $1,500 per year.

So, in the case they would have the same salary for some x years the expression can be

Katherine salary along with increment= 55000+ 2500x

Max salary along with increment= 64000+ 1500x

Hence, equation ca be used to find x, the number of years it will take Katherine to earn the same salary as Max is 55,000x+2,500x=64,000+1500x.
