conclusions concerning cause-and-effect relationships are only possible when the method is used. a. survey b. experimental c. correlational d. descriptive
Conclusions concerning cause-and-effect relationships are only possible when the method is used by Experimental.
Cause and effect relationship is the concept that states about happening of a particular event causes another event to take place. Cause is the action that makes occurrence of effect. Cause is the reason because of which a event happens and effect is the result of that.
Conducting an experiment can clarify the concept to make it more understandable as conduction the experiment is the cause and the outcome is the effect caused due to experiment.
Other options are not appropriate as co-relational research measures two factors to understand relation without experimenting. Naturalistic observation is observing the happening of the natural surrounding and survey is recording the happening or event. Thus, the correct option is option(d).
The primary reason descriptive/correlational research cannot determine conclusively that variables have a cause-and-effect relationship is because in conducting researchThe researcher can't control occasions or control factors. A correlational report is a quantitative strategy for the look into in which you have at least 2 quantitative factors from a similar gathering of subjects, and you are attempting to decide whether there is a connection between the 2 factors.

an air conditioning system can circulate cubic feet of air per minute. how many cubic yards of air can it circulate per minute?
We know that ,
1 feet= 0.33 Yard
Given that .
An air conditioning circulate 1 cubic foot per minutes
So it circulates 0.33 Yards per minute .
an air conditioning system can circulate 360 cubic feet of air per minute. how many cubic yards of air can it circulate per minute13.32 yards per minute
Given that an air conditioning system can circulate 360 cubic feet of air per minute. This is the rate of cubic feet per minute. That is,
Rate = volume/time. Which is
360 = volume/ 1
Volume = 360 cubic feet
Convert cubic feet to cubic yard
1 cubic foot = 0.037 cubic yards
Multiply this by 360
Cubic yards = 360 × 0.037
Cubic yards = 13.32
Therefore, if 360 cubic feet can circulate air per minute, this is equal 360 cubic feet of air per minute. how many cubic yards of air can it circulate per minute to 13.32 cubic yards of air which can circulate air per minute

Given the rule what is the new coordinate? Show all of your work.
Rule: (x, y) → (x - 7.5, y + 6.8)
Original coordinate: (5, 3)
Using translation concepts, the new coordinates are given as follows:
(-2.5, 9.8).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.
For this problem, the rule is given as follows:
(x, y) → (x - 7.5, y + 6.8)
This means that the figure is shifted:
7.5 units left.6.8 units up.The original coordinate is given by:
(5,3), meaning that x = 5 and y = 3.
Applying the rule, we have tat:
5 - 7.5 = -2.5.3 + 6.8 = 9.8.Hence the new coordinates are given as follows:
(-2.5, 9.8).

Let's say I get 18 from subtracting, and there is a 4 in the hundreds place, then 18 becomes 184 subtracted by any number below it that the divisor can multiply to.Note: Anytime 2 negative numbers are divided by each other, they will have a positive quotient.tolerance is an allowance made for imperfections in a manufactured object. the manufacturer of an oven specifies a temperature tolerance of ±15ºf. this means that the temperature inside the oven will be within 15ºf of the temperature to which it is set. write an absolute value equation to find the maximum and minimum temperatures inside the oven when the thermostat is set to 400ºf. let t represent the temperature inside the oven.
The highest temperature recorded was 415°F(maximum).
At its lowest, the temperature is 385°F(minimum).
How to to find the maximum and minimum temperatures ?The function of absolute value calculates the separation between a point and an origin.

then the solution is
[tex] - a \leq \: x \: \leq \: a[/tex]
according to the question
Temperature T is set to 400°F with a tolerance of 15°F, meaning that the absolute difference between T and 400°F may not be greater than 15°F; in other words:
[tex] |T - 400| \leq \: 15[/tex]
now apply the solution
[tex] - 15 \leq \: T - 400 \leq \:15[/tex]

x= -136 and x = 80
x=-112 and x = 80
x= -80 and x = 80
Answer:
x = -136 and x = 80
Step-by-step explanation:
|(1/4)x +7| - 3 = 24
|(1/4)x + 7| = 27 (transpose 3 and it becomes positive)
now:
(1/4)x + 7 = 27 (first solution)
(1/4)x = 20
x/4 = 20
x = 20×4
x = 80
(1/4)x + 7 = -27 (second solution)
(1/4)x = -34
x/4 = -34
x = -34×4
x = -136

The slope of the line AB which passes through the points (4, 5) and B(9, 7) is 2/5.
According to the given question.
We have a line AB containing the points A(4, 5) and B(9, 7).
Here, we have to find the slope of line AB.
As we know that, as we know that, the slope of a line is the ratio of the amount that y increases as x increases some amount.And the slope formula is m=(y2-y1)/(x2-x1) if a lines passes through the point (x2, y2) and (x1, y1).
Therefore, the slope of the line AB which passes through the points (4, 5) and B(9, 7)
