The probability of picking a lime or bubblegum jellybean followed by a papaya jellybean is 425/2162, which is approximately 0.196 when rounded to three decimal places.

The subject of this question is probability, a mathematical concept. Here is how we would calculate the answer to the student's query:

First, add up the total number of jelly beans in the jar, which gives us 47 jelly beans (12 lime + 17 papaya + 5 mango + 13 bubblegum). The total probability of picking a lime or bubblegum jelly bean is the probability of picking lime or bubblegum jelly beans divided by the total number of jelly beans.

The probability of picking a lime or bubblegum jelly bean is 25/47 (12 lime + 13 bubblegum = 25; 25/47).

After picking a lime or bubblegum jellybean, there are now 46 jellybeans left. Hence the probability of picking a papaya jellybean is 17/46.

Now, to get the total probability of picking a lime or bubblegum jellybean followed by a papaya jellybean, you multiply these two probabilities together.

The result will be (25/47) × (17/46) = 425/2162, which can be simplified to approximately 0.196 when rounded to three decimal places.

The correct probability, as a fraction, of selecting either a lime or bubblegum followed by a papaya is [tex]\(\frac{25}{341}\)[/tex].

To find this probability, we need to calculate the probability of each individual event and then multiply them together because we are dealing with two independent events: first selecting a lime or bubblegum, and then selecting a papaya.

 First, let's find the total number of jelly beans:

Total jelly beans = lime + papaya + mango + bubble gum

Total jelly beans = 12 + 17 + 5 + 13

Total jelly beans = 47

Now, let's calculate the probability of selecting either a lime or bubblegum:

Probability of selecting lime = Number of lime jelly beans / Total number of jelly beans

Probability of selecting lime = 12 / 47

Probability of selecting bubblegum = Number of bubblegum jelly beans / Total number of jelly beans

Probability of selecting bubblegum = 13 / 47

 Since we want the probability of selecting either a lime or bubblegum, we add these probabilities:

Probability of lime or bubblegum = Probability of lime + Probability of bubblegum

Probability of lime or bubblegum = (12 / 47) + (13 / 47)

Probability of lime or bubblegum = 25 / 47

 Next, we calculate the probability of selecting a papaya after selecting either a lime or bubblegum. Since we are not replacing the jelly bean after the first selection, the total number of jelly beans is now 46 (one less than before because one jelly bean has been removed).

Probability of selecting papaya = Number of papaya jelly beans / Total number of remaining jelly beans

Probability of selecting papaya = 17 / 46

Now, we multiply the probability of selecting either a lime or bubblegum with the probability of selecting a papaya:

Probability of lime or bubblegum followed by papaya = Probability of lime or bubblegum * Probability of papaya

Probability of lime or bubblegum followed by papaya = (25 / 47) * (17 / 46)

Finally, we simplify this expression:

Probability of lime or bubblegum followed by papaya = (25 * 17) / (47 * 46)

Probability of lime or bubblegum followed by papaya = 425 / 2162

This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 1 in this case. So the fraction is already in its simplest form.

 Therefore, the probability of selecting either a lime or bubblegum followed by a papaya is [tex]\(\frac{425}{2162}\).[/tex]However, upon re-evaluating the calculation, it seems there was an error in the simplification process. The correct simplification is:

 Probability of lime or bubblegum followed by papaya = [tex]\(\frac{25}{341}\).[/tex]

Answer:

Step-by-step explanation:

VC = (1/3)·pi·r2·h

VC = volume of a cone

r = radius of base of cone = 6 cm

h = height

VC = (1/3)·pi·62·h

VC = 12·pi·h

VS = (4/3)·pi·r3

VS = volume of a sphere

r = radius of base of sphere = 3 cm

VS = (4/3)·pi·33

VS = 36·pi

Since the volume of the cone and the sphere are equal:

VC = VS

12·pi·h = 36·pi

Solve for h.

Answer:

A=363

Step-by-step explanation:

To solve the area of a kite you use

[tex] a = \frac{pq}{2} [/tex]

So 22×33=726 then divide that by 2 and you get 363.

The area of a kite with diagonals of 22 feet and 33 feet is calculated as half the product of its diagonals, resulting in an area of 363 square feet.

The area of a kite can be calculated by taking the product of the lengths of its diagonals and dividing by two. In the case of the kite with diagonals of 22 feet and 33 feet, we use the formula: Area = (diagonal1 × diagonal2) / 2. Substituting the given lengths into the formula, we get Area = (22 × 33) / 2.

To find the area, we multiply 22 feet by 33 feet which equals 726 square feet. Then we divide by 2, so the area of the kite is 363 square feet.

Answer:

First of all (3x + 50) is equal to (6x - 10) so (3x + 50) = (6x - 10) 3x + 50 = 6x - 10 60 = 3x 20 = x

Step-by-step explanation:

Answer:

Step-by-step explanation:

(3x + 50)(6x + -10) = 0

Reorder the terms:

(50 + 3x)(6x + -10) = 0

Reorder the terms:

(50 + 3x)(-10 + 6x) = 0

Multiply (50 + 3x) * (-10 + 6x)

(50(-10 + 6x) + 3x * (-10 + 6x)) = 0

((-10 * 50 + 6x * 50) + 3x * (-10 + 6x)) = 0

((-500 + 300x) + 3x * (-10 + 6x)) = 0

(-500 + 300x + (-10 * 3x + 6x * 3x)) = 0

(-500 + 300x + (-30x + 18x2)) = 0

Combine like terms: 300x + -30x = 270x

(-500 + 270x + 18x2) = 0

Solving

-500 + 270x + 18x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '2'.

2(-250 + 135x + 9x2) = 0

Factor a trinomial.

2((-50 + -3x)(5 + -3x)) = 0

2: 3 and 12: 18 form a proportion

Step-by-step explanation:

When the two ratios are equal then they are said to be in proportion.

[tex]$\frac{2}{3}[/tex]  ≠ [tex]$\frac{4}{12} = \frac{1}{3}[/tex]  

So 2:3 and 4:12 are not in proportion.

[tex]$\frac{2}{3}[/tex]  ≠ [tex]$\frac{6}{12} = \frac{1}{2}[/tex]

So 2:3 and 6:12 are not in proportion

[tex]$\frac{2}{3}[/tex]  ≠ [tex]$\frac{12}{18} = \frac{2}{3}[/tex]  

So 2:3 and 12:18 are in proportion

[tex]$\frac{2}{3}[/tex]  ≠ [tex]$\frac{12}{36} = \frac{1}{3}[/tex]

So 2:3 and 12: 36 are not in proportion

Answer: 5 units

Step-by-step explanation:

Based on the definition of an isosceles trapezoid, the length of XY is: 5 units.

An isosceles trapezoid is a trapezoid that has two legs that are congruent.

Therefore:

2a - 2 = a + 1

Add like terms

2a - a = 2 + 1

a = 3

XY = 3a - 4

Plug in the value of x

XY = 3(3) - 4

XY = 5 units

Therefore, based on the definition of an isosceles trapezoid, the length of XY is: 5 units.

Option A:

The equation used to solve for angle N is

 [tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]

Solution:

Given data:

MO = 6.2 cm

ON = 4.3 cm

MN = 3.6 cm

To find the equation to solve for angle N:

Using cosine formula,

 [tex]c^{2}=a^{2}+b^{2}-2 a b \cdot \cos C[/tex]

Here, a = 3.6 cm, b = 4.3 cm, c = 6.2 cm, and angle A = angle C

Substitute these in the formula, we get

 [tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]

The equation used to solve for angle N is

 [tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]

Hence option A is the correct answer.

Answer:

x = 9

Step-by-step explanation:

MN is a midline segment and is half the length of GH, thus

GH = 2 × MN, substitute values

15x - 45 = 10x ( subtract 10x from both sides )

5x - 45 = 0 ( add 45 to both sides )

5x = 45 ( divide both sides by 5 )

x = 9

The value of x is 4. So 40000 mg= 40 g.

Step-by-step explanation:

      The given is 40000mg = 10x g

Step:1

      Take given equation as equation (1)

                     40000 mg= 10x g.................(1)

      where, X is known value.

Step:2

      Standard value for mg to g for the purpose of conversion of units,

                      1 milligram = 0.001 gram   (or)

                      1 gram = 1000 milligram

Step:3

      From the standard data values,

                    = 40000 mg

      it converted mg to g by dividing 1000

                    = [tex]\frac{40000}{1000}[/tex] g

                    = 40 g.......................(2)

Step:4

       From the Equations (1) and (2),

                 40=10x

                  x=4

Result:

       The value of x is 4. So, 40000mg = 40 g.
