The table that represents a linear equation is the first one, and the line can be:

y = -4x - 1

A general linear function can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

Now, notice that if we evaluate the line in x + 1, we will get:

y = a*(x + 1) + b

y = a*x + a + b

So, for an increase of one unit on the variable x, we have a constant increase in the y value.

Now, if you look at the first table, you can see that for each increase of 1 unit on the value of x, the value of y decreases by 4.

So that is the table that can represent a linear function.

And the line is:

y = -4x - 1

Answer: False

Step-by-step explanation:

25% of the data is between Q1 and the median.

Answer:

B

Step-by-step explanation:

Let the two numbers be a and b.

The product of the two is 120 and their sum of their squares is 289. In other words:

\(\displaystyle ab = 120 \text{ and } a^2 + b^2 = 289\)

And we want to find the sum of the two numbers.

We can use the perfect square trinomial. Recall that:

\(a^2 + 2ab + b^2 = (a+b)^2\)

From the first equation, multiply by two:

\(2ab = 240\)

Add the two equations together:

\((a^2+b^2)+(2ab) = (289)+(240)\)

Simplify and rewrite:

\(a^2+2ab+b^2 = 529\)

Factor using the perfect square trinomial pattern:

\((a+b)^2 = 529\)

And take the square root of both sides:

\(\displaystyle a + b = \pm\sqrt{529} = \pm23\)

Hence, the sum of the two numbers is 23 or -23.

In conclusion, our answer is B.

Parte A: 32 yardas cuadradas por galón

Parte B: 13 pies cuadrados por galón de diferencia

Explicación paso a paso:

Parte A:

Para saber cuántas yardas cuadradas cubre cada galón, tienes que dividir 42 2/3 entre 1 1/3, lo que equivale a 32. Eso significa que cada galón de pintura cubre 32 yardas cuadradas.

Parte B:

Primero, tienes que convertir cuánto cubrió Ángela en yardas cuadradas a pies cuadrados. Como una yarda cuadrada equivale a 9 pies cuadrados, tenemos que multiplicar 32 por 9, lo que equivale a 288. Para encontrar la diferencia, debes restar 288 - 275, lo que equivale a 13.

Answer:

The simplified expression would be 4

Step-by-step explanation:

So since we have parentheses in this expression we have to use the steps of PEMDAS (parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

So the first step is to solve what's in the parentheses \((4+10)=(14)\\(6+5)=(11)\)

Then we multiply \(2(14)=28\\-3(11)=-33\)

Since we have simplified the equation so far let's write it out

\(9+28-33\)

Now we just solve the equation as written

Answer:

\(C_{22} = 389\)

\(Max(A_{31}) =376\)

Step-by-step explanation:

Given

See attachment for complete question

Solving (a): The entry C22

First, matrix C represents the inventory at the end of July.

The entry of C is calculated as:

\(C = Inventory - Sales\)

i.e.

\(C = \left[\begin{array}{ccc}543&356&643\\364&476&419\\376&903&409\end{array}\right] - \left[\begin{array}{ccc}102&78&97\\98&87&59\\54&89&79\end{array}\right]\)

\(C = \left[\begin{array}{ccc}543-102&356-78&643-97\\364-98&476-87&419-59\\376-54&903-89&409-79\end{array}\right]\)

\(C = \left[\begin{array}{ccc}441&278&546\\266&389&360\\322&814&330\end{array}\right]\)

Item C22 means the entry at the second row and the second column.

From the matrix

\(C_{22} = 389\)

Solving (b): The maximum A31 possible.

From the given data, we have:

\(Inventory = \left[\begin{array}{ccc}543&356&643\\364&476&419\\376&903&409\end{array}\right]\)

\(Unit\ Sales = \left[\begin{array}{ccc}102&78&97\\98&87&59\\54&89&79\end{array}\right]\)

From the matrices above.

A31 means entry at the 3rd row and 1st column.

So, the possible values of A31 are:

\(A_{31} = 376\)

and

\(A_{31} = 54\)

By comparison, 376 > 54

So:

\(Max(A_{31}) =376\)  

We are asked to determine the interest rate for a deposit compounded annually. To do that we will use the following formula:

Where "r" is the interest rate, "A" is the accumulated quantity, "P" the initial deposit and "t" is time. We will solve for "r" first by dividing both sides by "P":

Now we will take root on both sides:

Now we subtract 1 to both sides:

Now we replace the values:

Solving the operations:

Therefore, the interest rate is 5%.

What is equation?

An equation is a formula that uses the equals sign to connect two expressions to show that they are equal.

The correct approaches to solving the equation are those that lead to the correct solution. We can check which students are correct by solving the equation and seeing if their approach leads to the correct answer.

Two-fifths (5 + x) = 8

Multiplying both sides by 5 gives:

5/5 * two-fifths (5 + x) = 5/5 * 8

One-fifth (5 + x) = 8/5

One-fifth (5) + One-fifth x = 8/5

1 + One-fifth x = 8/5

Subtracting 1 from both sides gives:

One-fifth x = 3/5

Multiplying both sides by 5 gives:

x = 3

So the solution is x = 3.

From the given approaches, Nico, Aditi, and Erick are correct. Their approaches are equivalent to the correct approach:

Two-fifths (5 + x) = 8

(5/2) * two-fifths (5 + x) = (5/2) * 8

(5/2) * (5/5 + x/5) = 20/5

5/2 + (5/2)x/5 = 4

5/2 + x/2 = 4

x/2 = 3/2

x = 3

Answer:

The probability is 0.6796

Step-by-step explanation:

Given

Population Mean - 100

Population Standard Deviation - 25

As we know

z = x-μ/σ, where:

z is the standard score

x is the raw score  

μ is the population mean

σ is the population standard deviation

Z value for mean of sample = 95

z1 = -100+95/25 = -5/25 = -0.2

P value for Z = -0.2 is 0.2912

Z2 = 100-105/25 = 0.2

P(z > 0.2 = 1 - P(z ≤ 0.2) = 1 - 0.0294 = 0.9706

P(-0.2 < z < 0.2) = 0.9706 - 0.2912= 0.6796

fill in 4 for

f(4) = 3(5)^(4-2)

do the 4-2 subtraction first

f(4) = 3(5)^2

do the 5 to the 2nd power next.

f(4) = 3(25)

last, multiply.

f(4) = 75

This is just following the typical order of operations.

Answer:

Step-by-step explanation:

f/h = 10/8

f = 1.25h

f = 1.25(15)

f = 18.75 cups

f = 1.25(17)

f = 21.25 cups

f = 1.25(30)

f = 37.5 cups

f = 1.25(h)

flour (c)

according to the table

\(f \: \frac{5}{4} \: h \: = \: 1.25 \: h\)

{positive correlation}

when h = 15 ,

\(f = \frac{5}{4} \: \times 15 = 18.75\)

when h= 17 ,

\(f = \frac{5}{4} \times 17 = 21.25\)

The garden has a length of 37.5 yards and width of 37.5 yards as well as an opening of 12.5 yards.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the length and y represent the width.

150 yards of fencing is available, hence:

2(x + y) = 150

x + y = 75

y = 75 - x     (1)

The area (A) of the garden is given as:

A = xy

A = x(75 - x)

A = 75x - x²

The maximum area is at A' = 0

A' = 75 - 2x

75 - 2x = 0

x = 37.5 yards

y = 75 - x = 75 - 37.5 = 37.5

Opening of the garden = 1/3 * 37.5 = 12.5 yards
