<u>Answer:</u>

The correct answer option is A. positive.

<u>Step-by-step explanation:</u>

When an exponent or a power is an even number and the base is a negative number, the value is always positive.

Suppose we have a negative base - 3 and a power which is even, lets say, 6 so what we get is a positive value.

(-3)^6=729

Therefore, a negative base with even power is always a positive value.

Answer: A. positive

Step-by-step explanation:

We know that powers are written in this form:

b^m

Where "b" is the base and "m" is the exponent.

By definition, the exponent indicates how many times to base must be multiplied by itself. Then, if the base is negative and the exponent is an even number, you get:

(-3)^4=(-3)(-3)(-3)(-3)=81\\\\\\(-2)^2=(-2)(-2)=2\\\\\\(-5)^6=(-5)(-5)(-5)(-5)(-5)(-5)=15,625

Therefore, when an exponent of a power is an even number and the base is a negative number, the value is always positive.

Solve<br>0.9(7x + 14) = 1.5 - (x + 2)
Triss [41]

\\ \sf\longmapsto 0.9(7x+14)=1.5-(x+2)

\\ \sf\longmapsto 6.3x+12.6=1.5-x-2

\\ \sf\longmapsto 63x+12.6=-x-0.5

\\ \sf\longmapsto 63x+x=-0.5-12.6

\\ \sf\longmapsto 64x=-13.1

\\ \sf\longmapsto x=\dfrac{-13.1}{64}

\\ \sf\longmapsto x=0.2

A headline in a major newspaper read, "Breast-fed youth found to do better in school."a. Do you thinkthis statement was based on
Maurinko [17]

Answer:

Randomized experiment

Step-by-step explanation:

Such a statement is said to be Randomized experiment as the kids in the school have been selected at random and their performances are observed and recorded. Later it is inquired if they are breast fed or not. This information is later assessed and a conclusion is reached. This type of research or experiment is Randomized experiment.

Considering that the experiment is Randomized, the statement should be "Link found between breast-feeding and school performances". This statement does not restrict the performances of the student specifically on breast-feeding but shows a probable affect of it.
