Give an example of an experiment where a control group would not be necessary.

1 answer:

8 0

DoE studies, for example do not require control group, since they usually involve models in which the number of variables are substantially smaller than the number of experiments. The DoE analysis provides a description model that shows how the responses or output variables depend on the factor settings or input variables. As long as the unknowns are substantially less than the number of equations, there is very minimal risk of over-fitting.

Answer:

$log\boxed{7}$

Step-by-step explanation:

$log\frac{14}{3}+log\frac{11}{5}-log\frac{22}{15}$

$=log\bigg(\frac{14}{3}*\frac{11}{5}\bigg)-log\frac{22}{15}$

$=log\bigg(\frac{14*11}{3*5}\bigg)-log\frac{22}{15}$

$=log\bigg(\frac{154}{15}\bigg)-log\frac{22}{15}$

$=log\bigg(\frac{154}{15}\div\frac{22}{15}\bigg)$

$=log\bigg(\frac{154}{15}\times\frac{15}{22}\bigg)$

$=log\bigg(\frac{154}{22}\bigg)$

$=log\boxed{7}$

How to solve for f(x)=9??? Help please

Alinara [238K]

There is nothing to solve for. You stated a constant function, where f(x) will always be 9.

What is the slope of a line that passes through the origin and the point (-2,1)?

Mazyrski [523]

Answer:

The slope would be -1/2.

Step-by-step explanation:

Since, the midpoint of the segment joining the points P (0, -4) and B (8, 0),

= ( 4, -2 ),

Now, the slope of the line passes through the origin and the point ( 4, -2) is,

= -1/2

A group of students and teachers are going on a field trip? One ninth of the group will fit on 1/3 of a school bus. How many bus

solniwko [45]

3/9 will fit on one bus so it will take 3 buses to fit 9/9 of the students, which 9/9 is the whole group.

Which equation can be used to find the value of b if side a measures 8.7 cm? 8.7 + b = 54.6 17.4 + b = 54.6 26.1 + b = 54.6 34.8

Ipatiy [6.2K]

We can't say. You never told us how side-b is related to side-a.
Are they in the same square ? Are they in the same triangle ?
Are they sides of the same box ? Are they on the same planet ?
