Step-by-step explanation:

Step one:

given data

initial count of fish= 850

final count of fish= 500

Required

% decrease

Step two:

% decrease= final-initial/initial*100

substitute

% decrease= 850-500/850*100

% decrease=350/850*100

% decrease= 0.41*100

% decrease= 40.1%

The percent decrease is approximately 40%.

Answer:

The percent decrease is approximately 70%

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)

Answer:

y = 4x +1

Step-by-step explanation:

6x + 1 = y + 2x

First you need to solve for y, so then you need to

1. Combine like terms

So since there isn't anything to combine we can more on.

2. Make Y by itself

You need to subtract the 2x from both side to get the answer

Answer:

9/10 in simpliest form is 9/10

Step-by-step explanation:

In order to simplify a fraction there must be:

1. A number that will divide evenly into both the numerator and denominator so it can be reduced. No such number exists for 9 and 10.

or

2. The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number. 9 is not greater than 10.

9/10 as a decimal: 0.9

9/10 as a percent: 90%

I see what's happening here

You're face to face with greatness

Honestly, I can go on and on

I could explain every natural phenomenon

The tide, the grass, the ground

Oh, that was me I was messing around

I killed a snake, I buried its guts

Sprouted a tree, now you've got coconuts

What's the lesson?

What is the takeaway?

Don't mess with Maui when he's on a breakaway

And the tapestry here in my skin

Is a map of the victories I win

Look where I've been, I make everything happen

Look at that mean mini Maui just tikkity tappin'

Singing and scratchin'

Flipping and snappin'

People are clappin', hearing me rappin'

And bring the chorus back in

Well anyway, let me say you're welcome

For the wonderful world you know

Hey, it's okay, it's okay

You're welcome

Well, come to think of it, I gotta go

Hey, it's your day to say

You're welcome

'Cause I'm gonna need that boat

I'm sailing away, away

You're welcome

'Cause Maui's the ultimate guy

You're welcome!

You're welcome!

Answer:

Area of carpet = 177.625 ft²

Step-by-step explanation:

Given:

Length of room = [tex]14\frac{1}{2}[/tex] = 14.5 ft

Width of room = [tex]12\frac{1}{4}[/tex] = 12.25 ft

Find:

Area of carpet

Computation:

Area of carpet = lb

Area of carpet = (14.5)(12.25)

Area of carpet = 177.625 ft²

Micheal estimation = 15.5 x 12.25 = 189.875

Tracy estimation = 12.25 x 15.5 = 189.875

Both wrong.

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]

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.
