if dr. lintz tried to make inferences about the outcomes of individuals based on her data of state legislatures, what mistake would she be making?

Answers

A unit of analysis is merely the entity under investigation. This is generally individuals but in case of Dr. Lintz, it really is state legislatures. The variables record information about the legislative bodies themselves, rather than the individuals who make up those bodies.

What is state legislatures?

A state legislature is a broad term that refers to the legislative body in any of the 50 states in the United States. The formal name differs from one state to the next.

Some key features regarding the state legislatures are-

Every state (except Nebraska) has a bicameral legislature, which means the legislature is divided into two separate legislative chambers (or "houses"); Nebraska does have a unicameral, or one-chamber legislature. The smaller chamber is called the "Senate" in all bicameral legislatures and is commonly referred to as the "upper house." The smaller chamber generally, but not always, has the exclusive power to approve appointments made by the governor and to attempt articles of impeachment.

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.

Answers

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.

A less-than-compound inequality is represented by:

[tex] |x| \leq a[/tex]

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]

then simplify this

[tex]T - 400 \ge \: - 15 \\ T \geq \: - 15 + 400 \\ T \geq \: 385[/tex]

[tex]T - 400 \leq \: 15 \\ T \leq \: 15 + 400 \\ T \leq \: 415[/tex]

Hence, The highest temperature recorded was 415°F(maximum).

At its lowest, the temperature is 385°F(minimum).

x= -136 and x = 80
x=-112 and x = 80
x= -80 and x = 80

Answers

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

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)

conclusions concerning cause-and-effect relationships are only possible when the method is used. a. survey b. experimental c. correlational d. descriptive

Answers

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 research

The 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.

Given the rule what is the new coordinate? Show all of your work.

Original coordinate: (5, 3)

Answers

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).

an air conditioning system can circulate 360 cubic feet of air per minute. how many cubic yards of air can it circulate per minute​

13.32 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
