Answer:

10,932,240

Step-by-step explanation:

According to the Naspa World list American english have 16,564 6-letters words. Now about the special characters we have the next list  !"#$%&'()*+,-./:;<=>[email protected][\]^_`{|}~ and considering the space as a special character we have a total of 33 special characters. For numbers we have a total of 10 digits.

Then to know how many possibles exists we have to find how many possibles are for the last two characters then.

33\cdot10=330

That is the amount os possibles if always the special character go before de number, but as the number could be before the special character we have to multiply this quantity by 2.

Then we have 16,564 words for the first 6 characters and 660 options for the last two. To know the total amount of possibilities we just need to multiply this numbers, then:

16,564\cdot660=10,932,240

Hello.

From our initial value, the price is $21 for 1 hour. After this, each hour is $14 more. From this information, we can solve for how much parking would cost at 24 hours, or one day.

5, 77; 6, 91; 7, 105; 8, 119; 9, 133; 10, 147; 11, 161; 12, 175; 13, 189; 14, 203; 15, 217; 16, 231; 17, 245; 18, 259; 19, 273; 20, 287; 21, 301; 22, 315; 23, 329; 24, 343.

After 24 hours, the total price will be $343.

I hope this helps!

Question 3 "Try Again." Mary needs 3 feet of boondoggle for a craft project.
kati45 [8]

Answer:

$9.00

Step-by-step explanation:

We can use conversion factors to solve this equation. The multiplication sequence that I got is shown below:

\frac{3ft}{1} × \frac{12 in}{1ft} × \frac{0.25}{1in}

Our feet and inches cancel out and we get the final expression \frac{3*12*0.25}{1}, which is equal to 9, or $9.00.

Hopefully that was helpful! :)

What is (5.03x -8.03) - (3.5x +6.2)?
Kryger [21]

Answer:

1.53x−14.23

Step-by-step explanation:

<em>simplify: </em>

5.03x−8.03−(3.5x+6.2)

<em>Distribute the Negative Sign:</em>

=5.03x−8.03−1(3.5x+6.2)

=5.03x−8.03−1(3.5x)+(−1)(6.2)

=5.03x−8.03−3.5x−6.2

<em>Combine Like Terms:</em>

=5.03x−8.03+−3.5x−6.2

=(5.03x−3.5x)+(−8.03−6.2)

=1.53x−14.23

A) it is left skewed
B) the median is 5
C) the mean is 5.15
D) the mean would be more affected (a change of 1.05 versus a change of 0.5).

The majority of the data is to the right of the graph; this means it is left skewed.

To find the median, write all of the data values out:
2, 3, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7

The middle value is 5.

We find the sum of this set of values and divide by 13, the number of data points, to find the mean:
2+3+4+4+5+5+5+6+6+6+7+7+7 = 67/13 = 5.15

If we added an additional data value at 20, the new median would be 5.5.  The new mean would be (67+20)/14 = 6.2.  The mean changes more than the median.
