How do i round 186.282?

Answers

Well, first you need to decide what place you want to round it TO.

Example: Round it to the nearest hundredth:

The next larger hundredth is 186.29 .
The next smaller hundredth is 186.28 .
Now look at it.
186.282 is closer to 186.28 than it is to 186.29 .
So the nearest hundredth is 186.28 .

-- When 186.282 is rounded to the nearest hundredth, it becomes 186.28 .

Similarly . . .
-- When 186.282 is rounded to the nearest tenth, it becomes 186.3 .
-- When 186.282 is rounded to the nearest whole number, it becomes 186 .
-- When 186.282 is rounded to the nearest ten, it becomes 190 .
-- When 186.282 is rounded to the nearest hundred, it becomes 200 .
-- When 186.282 is rounded to the nearest thousand or anything larger,
it becomes zero.

I'm curious . . . where did this number come from ?

It happens to be one thousandth of the speed of light, in miles per hour.

Did it come up in science class, or did a science geek use it for
one of the problems in math ?

Okay so if you want to know how to Round all you have to remember is 4 or more add 1 more 4 or less just ignore.

If your rounding 186.282 in the tenths you would look in your tenths place and look at the number in the left. ( the number in the tenths place is 8)

So is 2 greater or lesser than 4?

its lesser.

so ignore the rest of the two numbers there ( 8 & 2)

And your answer would be 186.2

Two lines are parallel. The equation for the first line is y=-3x+5. Which of the following can't be the equation of the second line?A. y=-3x+2
B. x-3y=-3
C. 3x+y=-6
D. 6x+2y=2 Two lines are parallel. The equation for the first line is y=-3x+5. Which of the following can't be the equation of the second line?
A. y=-3x+2
B. x-3y=-3
C. 3x+y=-6
D. 6x+2y=2 @Mathematics

Answers

Parallel lines can be distinguished by looking at the value of their slopes. These equations should have the same value of the slope. We are given the equation,

y=-3x+5

From the choices, we see that A, C and D have the same slope with the equation. Therefore, the correct answer is B, it is the equation that can't be parallel with the given equation.

means per hundred hope its right

It means per CENT, per every cent that makes up to 100, or you could say per hundred, which is why everything is based off from 0 - 100 perCENT.

Consider that I have 4 sections of Stat 200. Section 001 has 40 students, section 002 has 40 students, section 003 has 30 students, and section 004 has 40, for a total of 150 students. I'd like to do a satisfaction survey with a sample size of 30, but I suspect that the section may change students' satisfaction with the course. a. Which sampling techniques could I use to ensure I get a representative sample from each section? (Check the two best answers!) A. Systematic Sampling B. Cluster Sampling C. Simple Random Sampling D. Stratified Sampling

Answers

Answer:

B. Cluster Sampling

D. Stratified Sampling

Step-by-step explanation:

B. Cluster Sampling: In cluster sampling, you divide your population (in this case, the students) into clusters (the sections) and randomly select some of those clusters for your sample. This method allows you to ensure representation from each section. You would randomly select a few sections (clusters) and survey all the students within those selected sections.

D. Stratified Sampling: In stratified sampling, you divide your population into subgroups (strata) based on certain characteristics (in this case, sections). Then, you randomly select samples from each subgroup in proportion to their size in the population. This ensures that each section is represented according to its proportion in the total population.

These methods will help you obtain a representative sample from each section while accounting for the different sizes of the sections in your Stat 200 course.

Using the equation y=ax^2+bx+c to represent a parabola on a graph, which statement is true?1) If b is negative, the parabola opens downward
2) If a is negative, the parabola opens upward
3) If a is positive, the parabola open upward
4) If c is negative, the parabola opens downward

Answers

Tha answer is 3) if a is positive, the parabola opens upward. You can see that when you imagine what happens when x is large. In that case bx + c is small compared to ax^2, and the value of the function is dominated by the terms ax^2. x^2 is positive always, so the sign of ax^2 is given by a. Then if a is positive the extreme values of the function (x positively large and x negatively large) are positive, which is the case when the parabola opens upward.
