a) mean: add all numbers and then divide them.. so:

3+9+10+5+8+5+9+11+10+3+10= 83

83 divided by 11 = 83/11 or 7 4/11

b) median: the middle number of the sequence but put in order first.. so:

smallest to largest: 3,3,5,5,8,9,9,10,10,10,11

so then middle number: 9

c) mode: most frequent (popular) figure/number.. so:

most frequent value: 10

d) range: difference between smallest number and largest number

so in this case: 11-3 = 8

e) positive direction

In the figure below, Z is the center of the circle. Suppose that OR=4, ST= 4, UZ= 6, and VZ=4x-6. Find the following.

Ann [662]

Answer:

x = 3 units

SV = 2 units

Step-by-step explanation:

In $\odot Z$ QR and ST are chords such that:

QR = ST = 4

That is both the chords are equal in measure.

Equal chords are at equal distance from the center of the circle. Therefore,

VZ = UZ

4x - 6 = 6

4x = 6 + 6

4x = 12

x = 12/4

x = 3 units

Since, perpendicular dropped from the center of the circle bisects the chord.

$\therefore SV = \frac{1}{2} ST$

$\therefore SV = \frac{1}{2} \times 4$

$\therefore SV = 2\: units$

9> -2m + 2 - 3

Tanya [424]

Answer:

Step-by-step explanation:

Given

9 > - 2m + 2 - 3, that is

9 > - 2m - 1 ( add 1 to both sides )

10 > - 2m

Divide both sides by - 2, reversing the symbol as a result if dividing by a negative quantity.

- 5 < m , thus

m > - 5 → A
