Answer:

2.03

Step-by-step explanation:

2.033

When you round to the nearest hundredth you look at the thousandths place and see if it is 5 or above. If it's 5 or above you round and change the hundredth place. ( 2.04 )

In this case it is lower than 5

So, it would be 2.03

Hope this helps dude

The round off the number 2.033 to nearest hundredth is 2.03.

Although the term "rounding" is a general one, we typically use the terms "round up" or "round down" to indicate whether the number has gone up or down after being rounded. When the rounded number is increased, then the given number is said to be rounded up, conversely, if the rounded number is dropped, then it is said to be rounded down.

We have to round off the number 2.033 to nearest hundredth.

When rounding to the nearest hundredth, check the thousandths place to see if it is 5 or higher.

If it's 5 or higher, you go around and change the hundredth place 2.04.

But here it is less than 5 which makes the round off 2.03.

The answer to your question is :

Explanatory variable <--------> The first freezer

Response variable <---> The time required for the water to turn into ice in each freezer

control group <------------------> The second freezer

An Explanatory variable in an experiment is the variable that has been changed/manipulated by the researcher for the purpose of the experiment/research it is an independent variable ( as seen in first freezer )

A Response variable is the outcome of an experiment that serves as an evidence of the effect of the explanatory variable. it is a dependent variable

The control group is the made up of the refrigerators whom are not cooled using the new formula of refrigerant ( i.e. the second freezer )

hence the explanatory variable is the first freezer, the response variable is the time required for the water to turn into ice in each freezer, while the control group is the second freezer.

Answer:

Good luck to whoever figures out the last one.

Step-by-step explanation:

Let's say we had a sample of 100 people. We'll split them into two equal groups of 50 each. The two groups will be the treatment and control groups. The treatment group, aka experimental group, is where the actual drug is given. The control group is where the fake drug is given. People in the control group must not know the pill is fake. For more info, check out the placebo effect. In short, this is when a person takes a fake pill and thinks they get better, and that positive mentality helps them actually get better.  

If both the treatment and control groups improve (on average) together, then that means the fake pill is just as good as the real thing. Consequently, it means the real pill isn't effective at all. If on the other hand the experimental group does better overall compared to the control group, then we can see that the real pill is doing what it's intended to do. Of course, there are a lot of complicated factors involved, as there is with anything dealing with medicine. I haven't mentioned anything about side effects or things of that nature. In this simplified viewpoint of the world, we're only considering the one factor of whether or not the drug clears up the psoriasis on the skin.

To make things fair, it's best to randomly generate numbers so that you randomly assign people into each group. That way you have representative samples. Also, when drawing the sample of 100 people, make sure that's as random as possible to help represent the population as best as possible. The fact that the people in the control group not knowing that they are taking the fake pill means we have a single blind experiment. A double blind experiment is when even the researchers are not sure who is taking the real pill vs the fake pill. Double blind experiments are encouraged to prevent the researcher's bias from affecting the results.

To keep participants from knowing whether or not they are in the control group, the common solution is to provide a sugar pill. The pill will not cause any side effects and will not cause any improvements to health. It's simply sugar. To the participant, it seems like the real thing since they can't taste the difference or detect anything seems different.

Answer:

Randomly select a sample of people with psoriasis. Randomly assign them to one of two groups. Give one group the​ treatment, and withhold it from the other group. Give both groups similar looking​ pills, so neither knows which group they are in.

Answer:

   (12, 4)

Step-by-step explanation:

The point (12, 4) is the only one in the doubly-shaded area of the graph. Of the choices offered, it is the only one that is a solution.

__

I prefer to use a graphing calculator to draw the graph and plot the points. That is more interesting to me than evaluating the inequalities over and over.

Here, we find the first inequality is only satisfied by the first point. We can rewrite it so we're not messing with fractions.

  y ≥ -5/6x +2

  6y ≥ -5x +12 . . . . multiply by 6

  5x +6y ≥ 12 . . . . . add 5x

Now, to check the points:

  (12, 4) -- 5(12) +6(4) ≥ 12 . . . true

  (0, -2) -- 5(0) +6(-2) ≥ 12 . . . not true

  (6, -7) -- 5(6) +6(-7) ≥ 12 . . . not true

  (-12, 7) -- 5(-12) +6(7) ≥ 12 . . . not true

Just to make sure, we can use the first point in the second inequality:

  (12, 4) -- 4 ≤ 5(12) -1 . . . true

The point (12, 4) would be a solution to the two inequalities.

Using the discriminant formula, we can determine if this equation is ever true:

b² - 4ac

Plug in the a, b, and c values from the equation:

(4)² - 4(1)(5)

16 - 20 = -4 < 0

Since the discriminant is less than 0, there are no zeros to the equation. Thus, the equation is never true.

It should be noted that the quadrilateral is a trapezoid.

A trapezoid is a quadrilateral with at least one pair of parallel sides. In a trapezoid, the parallel sides are called the bases, and the non-parallel sides are called the legs. The distance between the bases is known as the height or altitude of the trapezoid.

A trapezoid has two bases, which are parallel to each other. These bases can have different lengths or the same length, depending on the type of trapezoid.

The legs of a trapezoid are the non-parallel sides. They connect the bases and can have different lengths.

A trapezoid has four angles. The angles formed by the bases and legs are called the base angles, while the angles formed by the legs and non-adjacent side are called the diagonal angles.

Answer:

a = 98⁰

Step-by-step explanation:

According to the the triangle sum thereom, all angles in triangle add up to 180⁰.

m<a + m<b + m<c = 180⁰

m<a + 34⁰ + 48⁰ = 180⁰

m<a + 82⁰ = 180⁰

m<a + 82⁰ - 82⁰ = 180⁰ - 82⁰

m<a = 98⁰

Answer:

Step-by-step explanation:

The Pythagorean theorem tells you the square on the hypotenuse is equal to the sum of the squares on the other two sides. (This is the version you use for problem 2.)

This also means the square on one side is the difference between the square on the hypotenuse and the square on the other side. (Use this version for problems 1 and 3.)

1. ? = 200 in² -75 in² = 125 in²

2. ? = 576 km² + 100 km² = 676 km²

3. ? = 36 square units - 16 square units = 20 square units
