if two cardboard boxes occupy 500 cubic centimetres space, then how much space is required to keep 200 such boxes​

Answer:

Y= -2/5X

Step-by-step explanation:

the equation is y=mx + b

slope: -2/5x

y- intercept: 0

all you do is combined your slope and y-intercept together: Y= -2/5X , you dont need to add +0 because it gonna just still be the same as y= - 2/5x

Y= -2/5X or y= -2/5x + 0 is the same so it can be any of these 2 that you pick but the correct way is y= -2/5x

Answer:

Write the problem as a mathematical expression. (5,5), (5,−8)

Use y=mx+b to calculate the equation of the line, where m represents the slope and b represents the y-intercept. To calculate the equation of the line, use the y=mx+b format.

Slope is equal to the change in y over the change in x , or rise over run.

m=(change in y)/(change in x)

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called rise).

m=(y2−y1) / (x2−x1)

Substitute in the values of x and y

into the equation to find the slope.

m=(−8−(5)) / (5−(5))

Finding the slope m.

Undefined

x=5

Step-by-step explanation:

Answer:

m = undefined

Algebra I

Step-by-step explanation:

Step 1: Define

Point (5, 5)

Point (5, -8)

Step 2: Identify

(5, 5) → x₁ = 5, y₁ = 5

(5, -8) → x₂ = 5, y₂ = -8

Step 3: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Here we see that we have a number divided by 0. Since we know that we cannot divide any number by 0, our slope will be undefined. This will be a vertical line on a Cartesian plane of x = 5.

Answer:

x = 34°

Step-by-step explanation:

corresponding angles made by a transversal intersecting parallel lines are congruent.

Answer:

x = [tex]\frac{10}{3}[/tex] or [tex]3\frac{1}{10}[/tex]

Step-by-step explanation:

2x - 8 = 12 - 4x

1) Add 8 on boths sides:

2x - 8 + 8 = 12 - 4x + 8

2x = 20 - 4x

2) Add 4x to both sides:

2x + 4x = 20 - 4x + 4x

6x = 20

3) Divide 6 on both sides

[tex]\frac{6x}{6} = \frac{20}{6}[/tex]

x = [tex]\frac{10}{3}[/tex] or [tex]3\frac{1}{10}[/tex]

12b - 5c = 16 --(2)

(1)x3

12b + 39c = -72 --(3)

(3)-(2)

12b + 39c - 12b + 5c = -72-16

c = -2

Sub c = -2 into (1)

Answer:

C) -8-11x-2.

Step-by-step explanation:

First solve the expression,

-2(4 - 3x)+(5x-2) = 11x-10

A) 11x-10 = 11x-10

B) -8+11x -2 = 11x-10

C) -8-11x-2 does not equal 11x-10. Instead -8-11x-2 = -11x-10

D) -8+6x+5x-2 = 11x-10

Answer:

The function that can be used to describe the number (n) of bacteria after 2 minutes is;

[tex]P = 4 \cdot e^{\left(\dfrac{ln(32)}{5} \times 2\right)} \approx 4 \cdot e^{\left(0.693\times 2\right)}[/tex]

Step-by-step explanation:

The data in the table are presented as follows;

Number of bacteria; 4, 128, 4,096, 131,072

Number of minutes from initial state; 0, 5, 10, 15

The general equation for population growth is presented as follows;

[tex]P = P_0 \cdot e^{r\cdot t}[/tex]

Where;

P = The population after 't' minutes

P₀ = The initial population

r = The population growth rate

t = The time taken for the growth in population numbers

At t =  minutes. we have;

[tex]4 = P_0 \cdot e^{r\times0} = P_0[/tex]

∴ P₀ = 4

At t = 5, we have;

[tex]128 = 4 \cdot e^{r\times 5}[/tex]

[tex]\therefore e^{r\times 5} = \dfrac{128}{4} = 32[/tex]

[tex]ln\left(e^{r\times 5}\right) = ln(32)[/tex]

∴ r × 5 = ㏑(32)

r = ln(32)/5 ≈ 0.693

The number (n) of bacteria after 2 minutes is therefore;

[tex]P = 4 \cdot e^{\left(\dfrac{ln(32)}{5} \times 2\right)} \approx 4 \cdot e^{\left(0.693\times 2\right)}[/tex]

Answer: 12.96 m²

Step-by-step explanation:

The area of the piece of land that the flower beds were dug in is:

= Length * width

= 5.2 * 4.8

= 24.96 m²

The flower beds were 3 in number and all had the shape of a square.

Their area is:

= 3 * (Length * width)

= 3 * ( 2 * 2)

= 3 * 4

= 12 m² for all three flower beds

Remaining land:

= 24.96 - 12

= 12.96 m²

Answer: 2 independent sample test of proportions

Step-by-step explanation:

The teo independent sample test of proportion is also referred to as the two proportion z-test and it simply allows the researcher to compare the two proportions in order to ascertain if they're the same or not.

In this case, the null hypothesis will be that that the proportions given in the research are the same while the alternate hypothesis will be that there is a difference between the proportions given.

The kind of analysis that would be most adequate for the given study:

Test of 2 Independent Proportions.

The test of two independent proportions is characterized as the method of study in which samples are opted randomly and allowed to remain independent.

In such a study, a minimum of 5 failures and successes are considered to reach a conclusion.

In the given situation, the samples of males and females are random and permitted to stay free("continue after the mission") and evaluated after a time to take the deduction.
