which of the following statistical techniques can the psychologist use to determine the developmental score of a typical 4 year
anzhelika [568]

Your question is incomplete, as you have not listed the following statistical techniques.

But I wish to help you, with the correct answer, that is likely one of the option.

ANSWER : INFERENTIAL STATISTICS

Step-by-step explanation: Inferential statistics is a statistical inference, where conclusion is drawn using a set of data that are not gotten from the sample study, but are assumed to relate with the sample study. This type of statistics relies on a probability, that the assumed data used to analyze a sample can be used to study the properties of that sample.

Therefore, for a psychologist to determine the developmental score of a four year old child, without the child participating in the study, the psychologist is most likely to use the scores of other who as participated in the study, to infer as the same with the score of a four year old child.

1. Let f(x) = 7x2 – 5x + 3 and g(x) = 2x2 + 4x – 6.
olganol [36]

Answer:

f(x) + g(x) = 9x^{2} - x - 3

f(x) - g(x) = 5x^{2} - 9x + 9

g(x) - f(x) = -5x^{2} + 9x - 9

Step-by-step explanation:

f(x) = 7x^{2} - 5x + 3\ and\ g(x) = 2x^{2} + 4x - 6

Case 1:

f(x) + g(x)

= 7x^{2} - 5x + 3 + (2x^{2} + 4x - 6)

= 7x^{2} - 5x + 3 + (2x^{2} + 4x - 6)

= 9x^{2} - x - 3

Case 2:

f(x) - g(x)

= 7x^{2} - 5x + 3 - (2x^{2} + 4x - 6)

= 7x^{2} - 5x + 3 - 2x^{2} - 4x + 6

= 5x^{2} - 9x + 9

Case3:

g(x) - f(x)

= 2x^{2} + 4x - 6 - (7x^{2} - 5x + 3)

= 2x^{2} + 4x - 6 - 7x^{2} + 5x - 3

= -5x^{2} + 9x - 9

Romashka [77]

Answer:

V = d / t

Step-by-step explanation:

La velocidad se define como la relación entre la diatancia cubierta por un cuerpo y el tiempo necesario para cubrir esa distancia.

Si el tiempo empleado se da como (t)

La distancia recorrida se da como (d)

Podemos escribir la velocidad (V) en términos de disance y tiempo como;

V = d / t
