Vlad [161]
Substitute the given point (3, -2) in each condition
(i) y < -3; y ≤ (2/3)x - 4
-2 < -3 → False
Therefore, it is not a solution.
[Since the values of x and y must satisfy both the conditions, if one of them does not satisfy the condition then it is not necessary to check the other one.]
(ii) y > -3; y ≥ 2/3x - 4
-2 > -3 → True
y ≥ 2/3x - 4
-2 ≥ -2 → True
Therefore, it is a solution.
(iii) y < -3; y ≥ 2/3x - 4
-2 < -3 → False
Therefore, it is not a solution.
(iv) y > -2; y ≤ 2/3x - 4
-2 > -2 → False
Therefore, it is not a solution.
Thereofore, the system of linear inequalities having the point (3, -2) in its solution set is y > -3; y ≥ 2/3x - 4. Hope it helps you.

The triangle is equilateral.                         Given

<K = < M = 60                                             Property of an equilateral triangle.

IE = IE                                                           Reflexive property

Proof

  • <IEK = <IEM  = 90                                  Property of perpendicular
  • <EIK = 180 - 60 - 90                              All triangles have 180 degrees
  • <EIK = 30                                               Subtraction
  • <MIK = 180 - 60 - 90                             All triangles have 180 degrees
  • <MIK = 30                                              Subtraction
  • <MIE = <KIE                                           Both = 30 degrees
  • IE = IE                                                     Reflexive property
  • <IEK = <MEI                                            Both are right angles.

Which table shows no correlation? A 2-row table with 7 columns. The first row is labeled x with entries 3, 5, 6, 8, 10, 14, 15.
olga nikolaevna [1]

Answer:

  Table 3

Step-by-step explanation:

Data shows no correlation when it has no trend in relation to the x-values. The data of table 3 both increases and decreases as x gets larger, so shows less correlation than the other tables.

This is verified by the computation done using a spreadsheet.

  Table 3 shows no correlation
