First distribute the negative to the second equation which would give you:

25x^2 - 14xy + 4 -7x^2 + 9y + 2xy + 7

Since addition is commutative. you can now just add like terms.

18x^2 - 12xy + 9y + 11

Identify all of the expressions that result in a difference of 1\4 . A) 2\10 − 1\6 B) 3\4 − 1 4 C) 2\3 − 5\12 D) 7\8 − 3\12 E) 1
MatroZZZ [7]

The expressions that result in a difference of 1/4 are; Choice C) 2\3 − 5\12 and Choice E) 1/2 − 1\4

For Choice A; 2\10 − 1\6

  • = 6/30 -5/30

  • = 1/30

For Choice B; 3\4 − 1 4

  • = 2/4

  • = 1/2

For Choice C; 2/3 - 5/12

  • = 8/12 - 5/12

  • = 3/12

  • = 1/4

For Choice D;. 7\8 − 3\12

  • = 21/24 - 6/24

  • = 15/24

  • = 5/8

For Choice D; 1/2 − 1\4

  • = 2/4 - 1/4

  • = 1/4

In essence, the expressions that result in a difference of 1/4 are; Choice C) 2\3 − 5\12 and Choice E) 1/2 − 1\4

Select the TRUE statement for completely random design.
Marysya12 [62]

Answer:

d.)The experimental units are assigned randomly to exactly one control group and one or more treatment groups

Step-by-step explanation:

Completely randomized design can be regarded as a type of experimental design in which the experimental units are assigned randomly for different treatments. This experimental design is utilized in cases whereby experimental units are seen to be “uniform" this implies that no uncontrolled factor in the experiment. completely randomized designs are engaged in studying effects of one primary factor by ignoring other nuisance variables it perform comparison of values of a response variable taking into account of the different levels of that primary factor. It should be noted that in completely random design, the experimental units are assigned randomly to exactly one control group and one or more treatment groups
