The probability that the first 2 ribbons removed from the bag are yellow is [tex]\(\frac{1}{51}\)[/tex].

First, let's calculate the probability of drawing the first yellow ribbon. There are 3 yellow ribbons and a total of 8 red, 7 green, and 3 yellow ribbons, which sums up to 18 ribbons in total. So, the probability of drawing the first yellow ribbon is:

[tex]\[ P(\text{first yellow}) = \frac{\text{Number of yellow ribbons}}{\text{Total number of ribbons}} = \frac{3}{18} = \frac{1}{6} \][/tex]

After drawing the first yellow ribbon, there are now 17 ribbons left in the bag, with 2 yellow ribbons remaining. The probability of drawing the second yellow ribbon is:

[tex]\[ P(\text{second yellow | first yellow}) = \frac{\text{Number of remaining yellow ribbons}}{\text{Total number of remaining ribbons}} = \frac{2}{17} \][/tex]

Now, we multiply the two probabilities to find the probability that the first two ribbons drawn are yellow:

[tex]\[ P(\text{first two yellow}) = P(\text{first yellow}) \times P(\text{second yellow | first yellow}) = \frac{1}{6} \times \frac{2}{17} \]\[ P(\text{first two yellow}) = \frac{1 \times 2}{6 \times 17} = \frac{2}{102} = \frac{1}{51} \][/tex]

Answer:

$15.61

Step-by-step explanation:

483.62 - 218.25 = 265.37

265.37/17 = $15.61

If each student raises the same amount, how much more money must each student raise is: $15.61.

Using this formula

Amount raised=Current amount to raised-Old Amount raised /Number of students

Where:

Current amount to raised=$483.62

Old Amount raised =$218.25

Number of students=17

Let plug in the formula

Amount raised=483.62 - 218.25/17

Amount raised= 265.37/17

Amount raised= $15.61

Thus, if each student raises the same amount, how much more money must each student raise is: $15.61.

Answer:

Value of p is 1.2.

Now drag and drop the values as per explanation.

Step-by-step explanation:

Additive inverse of any number means a number which can be added to the original number to get

Two numbers are said to be additive inverse of each other if sum of both numbers is 0. For example if 5 is the given number then -5 will be it's additive inverse. So to find additive inverse, we basically change the sign of number.

Given number p is additive inverse off -1.2 so p must be 1.2.

Sum will obviously be 0.

So to graph them on number line, we make a point at -1.2, 1.2 and at 0 for their sum.

Answer:

The length of side BC is 18 units

Step-by-step explanation:

Perimeter of the rectangle: P=76 units

AB=4z

BC=3z+3=?

We need to determine z

The formula to calculate the perimeter of a rectangle is:

P=2(w+l)

Width: w=AB=4z

Length: l=BC=3z+3

Replacing in the formula:

76 = 2 [4z+(3z+3)]

Eliminating the parentheses:

76 = 2 [4z+3z+3]

Adding like terms:

76 = 2 (7z+3)

Solving for z: Dividing both sides of the equation by 2:

76 / 2 = 2 (7z+3) / 2

38 = 7z+3

Subtracting 3 both sides of the equation:

38-3 = 7z+3-3

Subtracting:

35 = 7z

Dividing both sides of the equation by 7:

35 / 7 = 7z / 7

Dividing:

5 = z

z = 5

Then:

BC=3z+3

Replacing z by 5 in the formula above:

BC = 3(5)+3

Multiplying:

BC = 15 + 3

Adding:

BC = 18 units

Final answer:

Each term is matched with its correct concept, revealing the fundamental concepts of biological macromolecules and their formation and breakdown through dehydration synthesis and hydrolysis.

Explanation:

Let's match each concept with its correct term:

Macromolecules such as proteins, carbohydrates, and nucleic acids are essential for life and are composed of smaller organic molecules called monomers. When these monomers join together through dehydration synthesis, they release a water molecule and form covalent bonds to create larger structures known as polymers. The opposite process, hydrolysis, involves adding water to break down polymers into monomers.

Answer:

x=0 , y=2

Step-by-step explanation:

x=y-2

4x+y =2

We can substitute the first equation in for x into the second equation

4*(y-2) +y =2

Distribute the 4

4y-8 +y =2

Combine like terms

5y-8 =2

Add 8 to each side

5y-8+8 = 2+8

5y= 10

Divide each side by 5

5y/5 =10/5

y=2

But we still need to find x

x = y-2

x = 2-2

x=0

Answer:

see explanation

Step-by-step explanation:

the rate of change is the measure of the slope m of the line

To calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, 27) and (x₂, y₂ ) = (5, - 8)

m = [tex]\frac{-8-27}{5-0}[/tex] = [tex]\frac{-35}{5}[/tex] = - 7 ← rate of change

the initial value is the y-coordinate of the starting point

That is y = 27 ← starting value

The rate of change for the linear function is -7 and the initial value is 27.

Answer:

Substitute 7 for a.

Simplify the equation after substituting the value for a.

Verify that a = 7 is correct when the result is a true statement.

Step-by-step explanation:

 –9(a – 5) = –18  

Distribute

-9a +45 = -18

Subtract 45 from each side

-9a +45-45 = -18-45

-9a = -63

Divide each side by -9

-9a/-9 = -63/-9

a = 7

To check the solution put a =7 back into the original equation

 –9(a – 5) = –18  

  -9(7-5) = -18

Simplify

-9(2) = -18

-18 = 18

Answer:

x = -1

Step-by-step explanation:

Subtract 3x from both sides

6x + 9 - 3x = 3x + 6 - 3x

3x + 9 = 6

Subtract 9 from both sides

3x + 9 - 9 = 6 - 9

3x = -3

Divide both sides by 3

3x/3 = -3/3

x = -1

Answer:

BE : EC = 1 : 3

Step-by-step explanation:

Consider triangles AKD and EKB. In these triangles

Then ΔAKD is similar to ΔEKB by AAA theorem.

Similar triangles have proportional corresponding sides:

[tex]\dfrac{AD}{EB}=\dfrac{AK}{EK}=\dfrac{DK}{KB}.[/tex]

Since [tex]\dfrac{DK}{KB}=\dfrac{4}{1},[/tex] then [tex]AD=4BE.[/tex]

Opposite sides in parallelogram have the same lengths, then [tex]BC=AD.[/tex]

Now

[tex]BC=BE+EC,\\ \\BC=\dfrac{1}{4}BC+EC,\\ \\EC=BC-\dfrac{1}{4}BC=\dfrac{3}{4}BC.[/tex]

Find the ratio

[tex]\dfrac{BE}{EC}=\dfrac{\frac{1}{4}BC}{\frac{3}{4}BC}=\dfrac{1}{3}.[/tex]

The ratio of BE:EC is 1:2.

We have Parallelogram ABCD

Point K on diagonal BD such that BK:DK = 1:4

The extension of AK meets BC at point E

Since BK:DK = 1:4,

we know that BK = 1/5 * BD

and DK = 4/5 * BD.

AK extends to meet BC at point E means that AE is parallel to BD and BE is parallel to AK.

pair A,B,C,D,K,E;

A = (0,0);

B = (5,0);

C = (5,5);

D = (0,5);

K = (3.5,0);

E = (3.5,2.5);

Since AE is parallel to BD and BD is a diagonal of parallelogram ABCD, we know that AE bisects BD. This means that AE = BD/2 = 3/5 * BD.

Since BE is parallel to AK and AK is a diagonal of parallelogram ABCD, we know that BE bisects AK. This means that BE = AK/2 = 1/5 * BD.

Therefore, the ratio of BE:EC = 1/5 * BD

: 2/5 * BD

= 1:2.

Answer:

Y=2x-3

Step-by-step explanation:

Hi there! :)

Answer:

y = 2x - 3

Step-by-step explanation:

The slope intercept equation looks like this : y = mx + b

Where "m" is the slope and "b" is the y-intercept.

Your y-intercept = -3 → SO, b = -3

Your slope = 2 → SO, m = 2

Replace the values of "b" and "m" in the equation, and you're done:

y = mx + b

y = 2x - 3
