1. You could break them up:
10+30+20+10=70
6+5+4+4=19
70+19=89

2. Separate to groups:
16+35=51
24+14=38
51+38=89

I need the answer to a parts I-iii and the answer to b

fomenos

Answer:

i) Mean = 72

ii) Median = 72

iii) Mode = 72

69, 70, 71, 72, 72, 72, 73, 74, 75

Step-by-step explanation:

a. To find mean, median and mode

It is given that all the 9 students get 72 marks.

Therefore the data set be,

72, 72, 72, 72, 72, 72, 72, 72 72

i) mean = (sum of data)/(total number of data)

= (9 * 72)/9 = 9

ii) Median - Central data in the data set when arranging ascending or descending order

72, 72, 72, 72, 72, 72, 72, 72 72

Median = 72

iii) Mode - Most repeating data in the data set

Here mode = 72

b). To find a data set

69, 70, 71, 72, 72, 72, 73, 74, 75

Here Mean, mode and median are all 72

Which function is a quadratic function? F(x) =2x^2, g(x) =5x^3,k(x)=-x,b(x)=-9x^4

Katen [24]

Answer:

F(x)=2x^2

Step-by-step explanation:

Basically, a quadratic function has x^2 in it (standard form ax^2+bx+c with non-zero a). The others have x^3, -x, x^4, etc., which clearly are NOT x^2.

Three dressers are places side by side. One dresser is 5 feet 11 inches wide, another is 5 feet 6 inches wide, and the third is

Sidana [21]

5'-11" + 5'-6" + 5'-9" [add feet, then add inches]
= 15'+(11+6+9)"=15'+26"=15'+2'+2"
=17'-2"

The answer i'm so confused

Elena L [17]

Slope: rise over run, for any straight line. Example: y=mx + b

Constant of proportionality: a constant by which you multiply your independent variable (x) to get a specific value of the dependent variable (y). Example: y=kx.

The main difference here is that y=mx+b may or may not pass through the origin, whereas y=kx always passes through the origin.

Both k and m are "slopes," with k pertaining to direct variation y=kx, and m pertaining to slope of a line which may or may not pass through the origin.

In this limited sense, both k and x are slopes. k could be the slope of a straight line passing thru the origin, same as m, but m could not be the constant of proportionality if the line in question does not pass through the origin.
