Answer:

In analytic geometry, a point indicates a location on the coordinate plane through (x,y) coordinates.

On the other had, a point doesn't have dimension, that is, it doesn't have length or with, it just indicates location.

Similarly, a line has length but no width, that is, a line can describe an specific length, that it, because a line can be defined as subsequent points one after another, forming only one dimension, the length.

The third option is not true, because a distance along a line is actually a segment, which has to have an initial point and an ending point.

At last, a plane does consist of an infinite set of points, this is absolutely true, because a plane extends to the infinite as line do.

Therefore, the right answer are first and last one.

Given the number, two-fifths, generate its equivalent forms as a fraction, a decimal, and a percent. In addition, give a real wo

vichka [17]

The number in the three different forms is as follows.

2/5 (fraction), 0.2 (decimal), and 20% (percent).

You could use percentages for the results of a poll. For example, if you held a poll for which flavour of ice cream is your favorite. Let's say you surveyed 100 kids and 50 kids voted chocolate, 30 vanilla, and 20 strawberry. Then you could say 20% voted for strawberry.

You could use the decimal form for money. For example, let's say you want to buy something that costs $10.20 and you only have 10 dollars. You could say that you would need 20 more cents, or $0.20.

As for the fraction, you could use this for measurements. For example, let's say you have a piece of fabric. You want to cut it up into 5 equal pieces, but only use two of those pieces. You could say that you would only use 2/5 of the fabric.

I hope I helped you out! If anything is wrong, please let me know about it! :)

Find the greatest common factor.<br> 2y^3, 8y

Ira Lisetskai [31]

Answer:

STEP1:Equation at the end of step 1

2y3 - 8y

STEP2:

STEP3:Pulling out like terms

3.1 Pull out like factors :

2y3 - 8y = 2y • (y2 - 4)

Trying to factor as a Difference of Squares:

3.2 Factoring: y2 - 4

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 4 is the square of 2

Check : y2 is the square of y1

Factorization is : (y + 2) • (y - 2)

Final result :

2y • (y + 2) • (y - 2)

An investment service is currently recommending the purchase of shares of Dollar Department Store selling at $18 per share. The

Answer:

0.2857 = 28.57% probability that in a year the shares will be selling between $21 and $24

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The price is approximately normally distributed with a mean of 20 and a standard deviation of 2.

This means that $\mu = 20, \sigma = 2$
