Answer:

$x=\frac{3g}{8(k+d)}$

Step-by-step explanation:

The best way is to use reciprocals. Remember that the reciprocal of a number x is 1/x. For example, the reciprocal of 2 is 1/2 and the reciprocal of 13 is 1/13. Applying the reciprocal on both sides:

$\frac{2}{3g} = \frac{1}{4x(k+d)}\\\frac{3g}{2} = \frac{4x(k+d)}{1}\\\frac{3g}{2} = 4x(k+d)\\$

Another way to see it is by switching on both side numerator and denominator.

Now we divide both side by the factors next to x, which are 4 and (k+d).

$\frac{3g}{2*4(k+d)} = \frac{4x(k+d)}{4(k+d)}\\\frac{3g}{8(k+d)} = x\\$

If f(1) = 2 – 2 anid 9(37)<br> and g(x) = x2 – 9, what is the domain of g(x) = f(x)?

lana66690 [7]

Answer:

Step-by-step explanation:

Let divide g(x) by f(x)

$\frac{ {x}^{2} - 9 }{2 - x {}^{ \frac{1}{2} } }$

The domain of a rational function cannot equal zero so let set the bottom function to zero.

$2 - x {}^{ \frac{1}{2} } = 0$

$x {}^{ \frac{1}{2} } = 2$

Square both sides

$x = 4$

Also we can simplify the bottom denomiator into a square root function

$2 - \sqrt{x}$

The domain of a square root function is all real number greater than or equal to zero because a square root of a negative number isn't graphable.

So we must find a answer that

Disincludes 4 from the interval
Doesnt range in the negative number or infinity)
Range out in positve infinity
The answer to that is B

Which the sampling method reflects the following:

Minchanka [31]

Answer:A. judgment sampling

Step-by-step explanation: Judgement sampling also known as judgemental sampling is a non probability sampling technique that gives the researcher the opportunity to choose his or her sampling based on his or her knowledge of the study subject and the samples.

In judgemental samplings are likely to have some bias based on some important part of the population that may not have been identified and considered during the sampling process.

Which of the following are variables are categorical, if any? (check all that apply)

alukav5142 [94]

Answer:

A) The brand of cars driven by Harvard instructors

C) The types of plants growing in yellowstone

Step-by-step explanation:

Categorical and numerical variables:

Numerical data can be expressed with the help of numerical.
Categorical data cannot be expressed by numerical.
They do no have any particular value.
They are the non-parametric data.
Categorical data are also known as qualitative data.

A) The brand of cars driven by Harvard instructors

Since the brands cannot be expressed in numerical, it is a categorical variable.

B) The age of randomly selected biology students.

The age of student are expressed in whole numbers or decimals. Thus, it is a numerical data.

C) The types of plants growing in yellowstone

Again, the type of plants cannot be expressed with the help of numerical. Thus, it is a categorical variable.
