Answer:

The exact probability that all three marbles drawn  will be red is [tex]\frac{1}{56}[/tex]

Step-by-step explanation:

Number of red marbles = 5

Number of blue marbles = 4

Number of Green marbles = 7

Total Number of marbles = 5+4+7=16

We are given that three marbles  are drawn out of the bag

Probability of getting 1 red marble on first draw=[tex]\frac{5}{16}[/tex]

Probability of getting 1 red marble on second draw= [tex]\frac{4}{15}[/tex]

Probability of getting 1 red marble on third draw=[tex]\frac{3}{14}[/tex]

So,the exact probability that all three marbles drawn  will be red=[tex]\frac{5}{16} \times \frac{4}{15} \times \frac{3}{14}=\frac{1}{56}[/tex]

Hence The exact probability that all three marbles drawn  will be red is [tex]\frac{1}{56}[/tex]

Final answer:

The exact probability of drawing three red marbles consecutively from a bag containing a mix of 16 marbles is 1 in 56, calculated by multiplying the probabilities of each draw without replacement.

Explanation:

The question asks for the exact probability that all three marbles drawn from a bag containing 5 red marbles, 4 blue marbles, and 7 green marbles will be red. To find this probability, we use the formula for conditional probability without replacement.

First, calculate the total number of marbles, which is 5 + 4 + 7 = 16 marbles. The probability of drawing a red marble first is 5 out of 16. Once a red marble is drawn, there are now 15 marbles left, and 4 of them are red. So, the probability of drawing a second red marble is 4 out of 15. Further, if a second red marble is drawn, there are now 14 marbles left, and 3 of them are red, making the probability of drawing a third red marble 3 out of 14.

The combined probability of all three events (drawing three red marbles in a row) happening is the product of their individual probabilities:

P(3 red marbles) = (5/16) * (4/15) * (3/14) = 60 / 3360 = 1/56

Therefore, the exact probability of drawing three red marbles in a row from the bag is 1 in 56.

Answer:

The ratio of the height of the cone to the height of the cylinder is 3 to 1

The ratio of the height of the cone to the radius of the sphere is 4 to 1

Step-by-step explanation:

First we need to know the volume of a cylinder, a cone and a sphere:

V_cylinder = pi*r^2*h

V_cone = (1/3)*pi*r^2*h

V_sphere = (4/3)*pi*r^3

If they have the same volume:

The ratio of the height of the cone to the height of the cylinder is:

V_cone / V_cylinder = 1

(1/3)*pi*r^2*h1 / pi*r^2*h2 = 1

(1/3) * h1 = h2

h1 / h2 = 3

So the ratio is 3 to 1

The ratio of the height of the cone to the radius of the sphere is:

V_cone / V_sphere = 1

(1/3)*pi*r^2*h / (4/3)*pi*r^3 = 1

h / 4r = 1

h / r = 4

So the ratio is 4 to 1

Answer:

Each member in the group that went to the candy store named  Sugar Shack

received a larger portion of a candy bar because each member in the group got  5/7 of a candy bar.

Step-by-step explanation:

Okay so first I am a visual learner so I drew a picture! I started with Sweet Dreams. I drew 4 candy bars and split each candy bar in 6 pieces. Each friend got 1/6 of each candy bar. This means if someone went to Sweet Dreams they got a total of 4/6 of a candy bar. Which is equivalent to  2/3. I then converted that into a decimal which is about .66 and then I went on to Sugar Shack. I then drew 5 candy bars split in 7ths. Each person got a seventh out of each candy bar. This means they got a total of 5/7. I then converted that into a decimal which is about .714. Since .71 is greater than .66 that means people at Sugar Shack got a larger portion. Hope this helps!!! Good luck on the assignment!

Each member in the group that went to the candy store named Sugar Shack received a larger portion of a candy bar because each member in the group got 0.71 of a candy bar.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given:

Two candy stores are offering free same-sized candy bars to groups of friends.

Both groups shared the candy bars equally among their members.

A group of six friends went to Sweet Dreams and received four candy bars to share.

That means,

the share of one member = 4/6 = 2/3 or 0.67

A group of seven friends went to Sugar Shack and received five candy bars to share.

That means,

the share of one member = 5/7 = 0.71.

Therefore, each member in the group got 0.71 of a candy bar.

The total surface area of the composite figure will be 134 square units.

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

Answer: $1500 was invested in the account earning 8%.

$3300 was invested in the account earning 12.5%.

$1850 was was invested in the account earning 7.5%.

Step-by-step explanation:

Let x represent the amount invested in the account earning 8%.

Let y represent the amount invested in the account earning 12.5%.

Let z represent the amount invested in the account earning 7.5%.

Penelope invested $6650 into theee investment accounts, earning 8%, 12.5%, and 7.5% simple interest per year. It means that

x + y + z = 6650- - - - - - - - - - -1

Interest earned from the $x investment is

8/100 × x = 0.08x

Interest earned from the $y investment is

12.5/100 × x = 0.125y

Interest earned from the $z investment is

7.5/100 × x = 0.075z

If the annual interest earned totaled $671.25, it means that

0.08x + 0.125y + 0.075z = 671.25- - - - - - - 2

The amount invested at 12.5% was $300 more than twice the amount invested at 8%. It means that

y = 2x + 300

Substituting y = 2x + 300 into equation 1 and equation 2, it becomes

x + 2x + 300 + z = 6650

3x + z = 6650 - 300

3x + z = 6350- - - - - - - - - 4

0.08x + 0.125(2x + 300) + 0.075z = 671.25

0.08x + 0.25x + 37.5 + 0.075z = 671.25

0.33x + 0.075z = 671.25 - 37.5

0.33x + 0.075z = 633.75- - - - - - - 5

From equation 4, z = 6350 - 3x

Substituting z = 6350 - 3x into equation 5, it becomes

0.33x + 0.075(6350 - 3x) = 633.75

0.33x + 476.25 - 0.225x = 633.75

0.33x - 0.225x = 633.75 - 476.25

0.105x = 157.5

x = 157.5/0.105

x = 1500

y = 2x + 300

y = 2(1500) + 300

y = 3300

Substituting x = 1500 and y = 3300 into equation 1, it becomes

1500 + 3300 + z = 6650

z = 6650 - 4800

z = 1850

Answer:

1/5

Step-by-step explanation:

We need to fill in the circles; on the left, we need to put the number of students who play an instrument. That information is given: it's 25.

In the middle, we need the number of students who both play an instrument and speak a foreign language: again, we know that's 16.

On the right, we need the number of students who speak a foreign language; that's 30.

Finally, there are 9 students who participate in neither of these activities, so place "9" outside the circles but still in the rectangle.

See the attachment.

Probability is basically (# times specific event can occur) / (# times general event will occur). Here, the specific event is getting a student who plays an instrument and speaks a foreign language, which is 16. The general event is just selecting a student; since there are 80 total students, that number would be 80.

Our probability is thus:

16 / 80 = 1/5

Answer:

16/41

Step-by-step explanation:

Outside both: 9

Intersection (both): 16

0nly "Play instrument": 25

Only "Speak Foreign language": 30

Total: 80

P(Language/Instrument)

= n(both)/n(Instrument)

Answer:

The next three terms of the sequence are 182.3, 273.5 and 410.3 respectively (all rounded to the nearest tenth value)

Step-by-step explanation:

A geometric sequence is one in which successive members are multiples of a constant common ratio.

From the sequence, we can identify that;

First term a = 36

common difference = 2nd term/first term = 3rd term/second term = 4th term/3rd term

Hence, common difference d = 54/36 = 81/54 = 1.5

The next three terms of the sequence are the 5th, 6th and 7th term respectively.

For the 5th term, we have 4th term × common ratio = 121.5 × 1.5 = 182.3

For the 6th term, we have 5th term × common ratio = 182.3 × 1.5 = 273.5

For the 7th term, we have 6th term × common ratio = 273.5 × 1.5 = 410.3

Step-by-step explanation:

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

Answer:

x = -2, y = 3

Step-by-step explanation:

x + 3y = 7

2x + 4y = 8

Make the x term the same for both equations by multiplying the first equation by 2.

Now you have two equations with the same x terms.

2x + 6y = 14

2x + 4y = 8

Take the larger equation from the smaller to remove the x terms from the equations.

2x + 6y = 14

                   -

2x + 4y = 8

2y = 6

y = 3

Put the known y term back into the equations to find the y term

3(3) + x = 7

9 + x = 7, x = -2

12 + 2x = 8

2x = -4, x = -2

Step-by-step explanation:

Hi, to answer this question, first, we have to subtract the amount of juice poured (1/8) to the amount of remaining juice before he poured some (1).

1-1/8 = 7/8 remaining juice

Since he pours the same amount into more glasses until the pitcher is empty, we have to divide the remaining juice (7/8) by the amount poured in each glass (1/8).

7/8 ÷ 1/8 = 7 glasses
