Answer:

Step-by-step explanation:

You want to know if the equation -6x+6x-6=2-5 is an identity, conditional, or inconsistent.

<h3>Simplified</h3>

The simplified equation, after combining like terms, is ...

-6 = -3

This is an "inconsistent" equation, always false.

How many sides does a regular polygon have if the measure of each interior angle is 1600?

Art [367]

Answer:

18 sides

Step-by-step explanation:

with regular polygons it is best to remember that:

(1) all the EXTERIOR angles add up to 3600

(2) 1 exterior angle+1 interior angle =1800

Work with the exterior angles. In this case:

1 int. <=180−160=200

No. of sides =36020=18

5(a - 2b) - 3(a - 2b) |use distributive property: a(b - c) = ab - ac

= 5a - 10b - 3a + 6b

= (5a - 3a) + (-10b + 6b)

= 2a - 4b

Forty-nine cities provided information on vacancy rates (in percent) for local apartments in the following frequency distributio

Nostrana [21]

Answer:

$E(X) = \frac{431.5}{49}= 8.81$

$s^2 = \frac{4780.25- \frac{(431.5)^2}{49}}{48} = 20.425$

$s= \sqrt{20.425}= 4.52$

Step-by-step explanation:

For this case we can calculate all the questions with the following table:

Class Midpoint(Xi) fi Xi*fi Xi^2 *fi

____________________________________

0-3 1.5 6 9 13.5

3-6 4.5 6 27 121.5

6-9 7.5 11 82.5 618.75

9-12 10.5 21 220.5 2315.25

12-25 18.5 5 18 1711.25

_____________________________________

Total 49 431.5 4780.25

We can calculate the expected value with the following formula:

$E(X) = \frac{\sum_{i=1}^n X_i P(X_i)}{n}$

And if we replace we got:

$E(X) = \frac{431.5}{49}= 8.81$

We can calculate the sample variance with the following formula:

$s^2 =\frac{\sum X^2 f -\frac{(\sum xf)^2}{n} }{n-1}$

And replacing we got:

$s^2 = \frac{4780.25- \frac{(431.5)^2}{49}}{48} = 20.425$

And the deviation would be just the square root of the variance like this:

$s= \sqrt{20.425}= 4.52$

If a male student is selected at random, what is the probability the student is a freshman?

Firlakuza [10]

The probability that the student selected at random is a freshman is; 29%

<h3>How to find the Probability?</h3>

From the given table;

Total number of male students = 4 + 6 + 2 + 2 = 14

Number of freshmen students = 4 students

Thus;

Probability that the student selected at random is a freshman is;

P(Freshman | Male) = 4/14 * 100% = 28.57% ≈ 29%

Given

The numbers, 1/2, 1/8, and 1/10.

To find: The least common denominator.

Explanation:

It is given that,

1/2, 1/8, and 1/10 .

Then,

Therefore, the LCM is,

$\begin{gathered} LCM=2\times2\times2\times5 \\ =40 \end{gathered}$

Hence, the least common denominator is 40.
