Answer:

No. of Plates Possible = 78624000 = 7.86 x 10⁷

Step-by-step explanation:

We have total 7 places to fill in order to form a plate. So, we see all the number of options available for each of the position:

No. of Options for First Place = 26 (All alphabets of English)

No. of Options for Second Place = 25 (Due to no repetition)

No. of Options for Third Place = 24 (Due to no repetition)

No. of Options for Fourth Place = 10 (Digits from 0 to 9)

No. of Options for Fifth Place = 9 (Due to no repetition)

No. of Options for Sixth Place = 8 (Due to no repetition)

No. of Options for Seventh Place = 7 (Due to no repetition)

Hence, the total possible plates that can be made are given by multiplying

the options to select in each place:

No. of Plates Possible = 26*25*24*10*9*8*7

No. of Plates Possible = 78624000 = 7.86 x 10⁷

Answer:

the value of x is x men just like spiderman and my favorite rapper is lil baby

Answer:

Given Initial investment = $12,000

Cost per unit = $11.50

Selling price per unit = $19

a. For x unit

Total cost = Initial investment + Cost per unit * no of unit

= 12,000 + 11.50(x)

c(x) = 12,000 + 11.50(x)

R(x) = Selling price per unit * no of items

R(x) = 19 * x

R(x) = 19x

b. Break even point = R(x) = C(x)

19x = 12,000 + 11.50x

19x - 11.5x = 12,000

7.5x = 12,000

x = 12,000 / 7.5

x = 1600

So, break even point x =  1,600

c. For Profit = $1,000

P(x) = 1,000

P(x) = R(x) - C(x)

1000 = 19x - (12,000 + 11.5x)

1000 =19x - 11.5x - 12000

7.5x = 12000 + 1000

7.5x = 13000

x = 13000/7.5

x = 1733.33

So x = 1733 units

Hence, 1733 units will yield for $1,000 profit

The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.

The speed   is the distance travelled per unit of time by a sound wave  

Speed of sound in water is [tex]1.46 \cdot 10^3[/tex]

Speed of sound in air is [tex]3.31 \cdot 10^2[/tex]

To find how much faster does travel , we need to subtract  the speed

To subtract we need to make the exponents same

[tex]1.46 \cdot 10^3\\14.6 \cdot 10^2[/tex]

Now we subtract ,

 [tex]14.6- 3.31= 11.29\\\\11.29 \cdot 10^2\\1.129 \cdot 10^3[/tex]

The sound travel [tex]1.129 \cdot 10^3 m/s[/tex] faster than the speed of sound in air.

Answer:

To get from step 1 to step 2, apply the distributive property to eliminate the parentheses.

To get from step 2 to step 3, combine like terms on the right side of the equation.

To get from step 3 to step 4, apply the addition property of equality to isolate the variable term.

To get from step 4 to step 5, apply the multiplication property of equality to isolate the variable, x.

To get from step 5 to step 6, apply the symmetric property to rewrite the equation with the variable on the left side.

Answer:

-2 degrees

Step-by-step explanation:

Divide -16 by 8:

-16/8

= -2

So, the average change in temperature each hour was -2 degrees.

The average change of weather dropped 2 degrees for every hour is snowed.

Here,

After 8 hours of snow, the temperature had changed by a total of -16 degrees.

We have to find the average change in temperature in each hour.

What is Average?

Average is the middle value of the given sets of values.

Now,

After 8 hours of snow, the temperature had changed by a total of -16 degrees.

Hence, The average change in temperature in each hour = -16 ÷ 8 = -2

Therefore, The weather dropped 2 degrees for every hour is snowed.

Answer:

The score of the student is  x = 779.42

Step-by-step explanation:

Generally we can mathematically represent the z-score as

         [tex]z = \frac{x - Mean}{ stDev}[/tex]

Here x is the score of the student

substituting 1045.7 for the Mean, 221.9 for the stDev and -1.2 for z we have  

          [tex]-1.2 = \frac{x - 1045.7 }{ 221.9}[/tex]

=>       [tex]-266.28 = x -1045.7[/tex]

=>     x  =  -266.28 + 1045.7

=>     x = 779.42

The student scored 779.42 for him to have a z score of - 1.2;

z score is used to determine by how many standard deviations the raw score is above or below the mean.

The z score is given by:

[tex]z=\frac{x-\mu}{\sigma/ } \\\\where\ x\ is\ raw\ score,\mu\ is\ mean, \sigma\ is\ standard\ deviation[/tex]

Given that μ = 1045.7, σ = 221.9 Hence for z = -1.2:

[tex]-1.2=\frac{x-1045.7}{221.9} \\\\x=779.42[/tex]

The student scored 779.42 for him to have a z score of - 1.2;
