What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, it is given that :

number of rows = m³

number of columns = m^(5)

Now, we have to find the number of tiles in a wall

= rows *  column

=  m³ *  m^(5)

= m^(3+5)

= m^(8)

hence, the number of tiles in a wall is m^(8)

#SPJ1

Answer: Events A and B are independent.

=============================================

Explanation:

Note how,

P(A)*P(B) = 0.5*0.2 = 0.1

which matches exactly with P(A and B) = 0.1

Therefore,

P(A and B) = P(A)*P(B)

is a true statement. This further leads to events A and B being independent.

Answer: C. [tex]B=\left[\begin{array}{ccc}1\\3\\-5\end{array}\right][/tex]

Step-by-step explanation: I got this right on Edmentum.

Several operations such as addition, subtraction, multiplication, etc. can be performed on matrices. The value of matrix B is:

[tex]B =\left[\begin{array}{c}1&3&-5\end{array}\right][/tex]

Given that:

[tex]A =\left[\begin{array}{ccc}2&4&-2\\4&-5&7\\2&7&5\end{array}\right][/tex]

[tex]AB =\left[\begin{array}{c}24&-46&-2\end{array}\right][/tex]

Let matrix B be:

[tex]B =\left[\begin{array}{c}a&b&c\end{array}\right][/tex]

The product of A and B is as follows:

[tex]\left[\begin{array}{ccc}2&4&-2\\4&-5&7\\2&7&5\end{array}\right] \times\left[\begin{array}{c}a&b&c\end{array}\right][/tex]

Multiply the rows of A to the column of B. So, we have:

[tex]AB =\left[\begin{array}{ccc}2a+4b-2c\\4a-5b+7c\\2a+7b+5c\end{array}\right][/tex]

This means that:

[tex]\left[\begin{array}{ccc}2a+4b-2c\\4a-5b+7c\\2a+7b+5c\end{array}\right] = \left[\begin{array}{c}24&-46&-2\end{array}\right][/tex]

By comparison, we have:

[tex]2a + 4b - 2c = 24[/tex] --- (1)

[tex]4a - 5b + 7c = -46[/tex] --- (2)

[tex]2a + 7b + 5c = -2[/tex] --- (3)

Multiply (1) and (3) by 2

[tex]2a + 4b - 2c = 24[/tex] --- (1)

[tex]4a + 8b - 4c = 48[/tex] ----- (5)

[tex]2a + 7b + 5c = -2[/tex] --- (3)

[tex]4a + 14b + 10c = -4[/tex] ---- (6)

So, we have:

[tex]4a - 5b + 7c = -46[/tex] --- (2)

[tex]4a + 8b - 4c = 48[/tex] ----- (5)

[tex]4a + 14b + 10c = -4[/tex] ---- (6)

Make 4a the subject in each of the equations

[tex]4a = -46 + 5b - 7c[/tex]

[tex]4a = 48 - 8b + 4c[/tex]

[tex]4a = -4 - 14b - 10c[/tex]

[tex]4a = 4a[/tex]. So, we have:

[tex]-46 + 5b - 7c = 48 - 8b + 4c[/tex]  and  [tex]-46 + 5b - 7c = -4 - 14b - 10c[/tex]

Simplify both expressions

[tex]-46 + 5b - 7c = 48 - 8b + 4c[/tex]

[tex]5b + 8b - 7c - 4c = 48 + 46[/tex]

[tex]13b - 11c = 94[/tex]

[tex]-46 + 5b - 7c = -4 - 14b - 10c[/tex]

[tex]5b+14b - 7c + 10c = 46-4[/tex]

[tex]19b + 3c = 42[/tex]

Make c the subject

[tex]c = \frac{42 -19b}{3}[/tex]

Substitute [tex]c = \frac{42 -19b}{3}[/tex] in [tex]13b - 11c = 94[/tex]

[tex]13b - 11 \times (\frac{42 - 19b}{3}) = 94[/tex]

Multiply through by 3

[tex]39b - 11 \times (42 - 19b) = 282[/tex]

Open bracket

[tex]39b - 462 + 209b = 282[/tex]

Collect like terms

[tex]39b + 209b = 282+462[/tex]

[tex]248b = 744[/tex]

Solve for b

[tex]b = \frac{744}{248}[/tex]

[tex]b = 3[/tex]

Solve for c

[tex]c = \frac{42 -19b}{3}[/tex]

[tex]c = \frac{42 - 19 \times 3}{3}[/tex]

[tex]c = \frac{-15}{3}[/tex]

[tex]c = -5[/tex]

Solve for a in [tex]4a = -4 - 14b - 10c[/tex]

[tex]4a = -4 - 14 \times 3 - 10 \times -5[/tex]

[tex]4a = 4[/tex]

Divide by 4

[tex]a = 1[/tex]

Recall that matrix B is:

[tex]B =\left[\begin{array}{c}a&b&c\end{array}\right][/tex]

Hence, the value of matrix B is:

[tex]B =\left[\begin{array}{c}1&3&-5\end{array}\right][/tex]

The functional model is a logical description of the functionalities (activities, events, procedures, and procedures) of the simulation model or content matter.

As per the given question, below is a list of values provided by a science teacher.

What function is responsible again for tables representing data that are

The chart with x and f(x) has been provided below.

The table shows that if [tex]x = \frac{1}{10}[/tex]  then [tex]f(x) =1[/tex]

Using the logarithm rule that is:

[tex]\log (10) = 1 \\\\\log (100) = 2.[/tex]

Substituting the values of x in [tex]f(x)= \log \frac{1}{x}[/tex]

When

[tex]x = \frac{1}{10}\\\\f(x)= \log \frac{1}{\frac{1}{10}}[/tex]

We can write it [tex]f(x) = \log(10) = 1[/tex]

If

[tex]x = \frac{1}{100}\\\\f(x)= \log \frac{1}{\frac{1}{100}}[/tex]

We can write it [tex]f(x) = \log(100) = 2[/tex]

Therefore, the final answer is "[tex]f(x)= \log \frac{1}{x} , x =/ 0[/tex]".

Answer:

60%

Step-by-step explanation:

In the camp 15 out of 25 boys chose to go swimming. 15 is 60% of 25, so 60% of boys chose to go swimming.

Important information:

We need to find the percentage of the boys who chose to swim.

The percentage of the boys who chose to swim is:

[tex]\text{\% of boys who chose to swim}=\dfrac{\text{Boys chose to go swimming}}{\text{Total boys}}\times 100[/tex]

                                              [tex]=\dfrac{15}{25}\times 100[/tex]

                                              [tex]=15\times 4[/tex]

                                              = 60

Therefore, 60% of boys chose to go swimming.

Net pay of Kevin is $440

Step-by-step explanation:

Pay per hour = $6.50

Total Hours worked= 60 hours

Total pay for 60 hours worked = 6.50 x 60 = $390

Amount received as tips = $148

Now, his pay would be: 390+148 = $538

Amount deducted for meals = $21

Now his pay would be = 538-21 = $517

Now, Pay of Kevin is $517

Payroll taxes deducted from pay = $77

Net pay of Kevin= 517-77 = &440

Answer:

[tex]\frac{1}{233974}[/tex] (1 out of 233974 chance of correctly guessing Alec’s password)

Step-by-step explanation:

First Part (letter in the password):

There are 26 letters in the alphabet, and there is only one letter in Alec’s password. So for that part, you have [tex]\frac{1}{26}[/tex] chance in finding the letter in the password.

Second Part (4 digit number in the password):

For the next part, the problem says that it’s a four digit number. So, out of all the numbers there are, what place value has four digits? It would be the thousands. That means from 1,000 to 9,999 (not including 10,000 too because that’s 5 digits) is the range of all the possible 4 digit numbers. So, how many numbers are in the range of 1,000 through 9,999? Well, all you do is subtract 1,000 from 9,999 (can be written as 9,999 - 1,000) and that equals 8,999. This means that there are 8,999 possible 4 digit numbers that can be guessed in Alec’s password. So that means you will have a 1 out of 8,999 chance in finding the 4 digit number in Alec’s password. This can be written as [tex]\frac{1}{8999}[/tex].

Final Part (solving it):

Finally, you need to multiply the two chances together (the chance in finding the letter times the change of finding the 4 digit number). This can be written as [tex]\frac{1}{26}[/tex] × [tex]\frac{1}{8999}[/tex], which equals [tex]\frac{1}{233974}[/tex].

Answer: [tex]\frac{1}{233974}[/tex] (1 out of 233974 chance of correctly guessing Alec’s password)
