A bag contains 8 blue marbles 6 red marbles and 4 green marbles what is the probability of selecting a blue marble replaced it in the bag and then selecting a red marble

Answers

Answer 1

Answer:

[tex]\dfrac{4}{27}[/tex]

Step-by-step explanation:

A bag contains 8 blue marbles 6 red marbles and 4 green marbles, 8 + 6 + 4 = 18 marbles in total.

The probability of selecting a blue marble is

[tex]P(\text{blue marble})=\dfrac{\text{Number of blue marbles}}{\text{Total number of marbles}}=\dfrac{8}{18}=\dfrac{4}{9}[/tex]

Then the blue marble was replaced in the bag.

The probability of selecting a red marble is

[tex]P(\text{red marble})=\dfrac{\text{Number of red marbles}}{\text{Total number of marbles}}=\dfrac{6}{18}=\dfrac{1}{3}[/tex]

The probability of selecting a blue marble replaced it in the bag and then selecting a red marble is

[tex]P=\dfrac{4}{9}\cdot \dfrac{1}{3}=\dfrac{4}{27}[/tex]

A surveyed was conducted at Holy Spirit High school where 50 students were randomly
chosen and asked whether they liked apples or bananas. Of the 50, 36 students said they
like apples, 30 students like bananas and 5 students do not like either apples or bananas.

How many students like both apples and bananas?

Answers

Answer:

26

Step-by-step explanation:

50 students were asked, and only 5 said that they did not like apples or bananas.This means that  45 students like either apples or bananas, or both of them. We will call these 45 students, the group of "45".We also know that, between these 45 students there are 36 who like apples and 30 that like bananas. This imply that, 45-36=9 students do not like apples, and 45-30=15 students do not like bananas.Then, there are 15 students within the group of "45" that do not like bananas, and 9 students within the group of "45" that do not like apples. This means that 9+15=24 students within the group of "45" only like bananas or apples. The rest of them, 45-24= 26 like both apples and bananas.

A survey of all beings on planet Tott found that 12 beings preferred
hab juice to all other juices. If 40 beings were surveyed altogether,
what percent of them preferred hab juice?

Answers

Answer:

4.8

12 x 40

100

= 4.8

Step-by-step explanation:

The percentage of beings that preferred hab juice, is 30% of beings preferring hab juice.

The question is asking to find the percentage of beings that preferred hab juice out of a total of 40 surveyed on planet Tott. To do this, we use the basic formula for percentage:

Percentage = (Part / Whole) * 100

In this case, 12 beings out of 40 preferred hab juice. So we have:

Percentage = (12 / 40) * 100 = 0.3 * 100 = 30%

Therefore, 30% of the beings surveyed preferred hab juice.

The arithmetic sequence 1, 3, 5, 7, 9, . . . represents the set of odd natural numbers. What is the explicit rule for the sequence? ak = ____ +____ (k - 1)

Answers

Answer:

The explicit rule is Ak = 1 + 2 * (k - 1)

Step-by-step explanation:

1. Let's review the information provided to us for finding the explicit rule for the sequence.

The arithmetic sequence 1, 3, 5, 7, 9, . . . represents the set of odd natural numbers.

2. Let's find the solution:

Ak = 1 + 2 * (k - 1)

For k = 1 ⇒ Ak = 1 + 2 * (1 - 1) = 1 + 2 * 0 = 1 + 0 = 1

For k = 2 ⇒ Ak = 1 + 2 * (2 - 1) = 1 + 2 * 1 = 1 + 2 = 3

For k = 3 ⇒ Ak = 1 + 2 * (3 - 1) = 1 + 2 * 2 = 1 + 4 = 5

For k = 4 ⇒ Ak = 1 + 2 * (4 - 1) = 1 + 2 * 3 = 1 + 6 = 7

For k = 5 ⇒ Ak = 1 + 2 * (5 - 1) = 1 + 2 * 4 = 1 + 8 = 9

For k = 6 ⇒ Ak = 1 + 2 * (6 - 1) = 1 + 2 * 5 = 1 + 10 = 11

For k = 7 ⇒ Ak = 1 + 2 * (7 - 1) = 1 + 2 * 6 = 1 + 12 = 13

Answers

Answer:

x=27°

Step-by-step explanation:

we know that

The Triangle Exterior Angle Theorem, states that: An exterior angle of a triangle is equal to the sum of the opposite interior angles

step 1

Find the measure of angle PLM

we know that

m∠PLM+m∠LPM=m∠PMN ----> by Triangle Exterior Angle Theorem

we have

m∠LPM=x°

m∠PMN=2x+72°

substitute

m∠PLM+x=2x+72°

m∠PLM=2x-x+72°

m∠PLM=x+72°

step 2

Find the measure of angle x

we know that

3x+m∠PLM=180° ----> by supplementary angles (form a linear pair)

we have

m∠PLM=x+72°  (see step 1)

substitute

3x+x+72°=180°

4x=180°-72°

4x=108°

x=27°

Answer:

By the given diagram,

PLM is a triangle,

K and N are points on line MN,

m∠KLP = 3x, m∠P = x, m∠PMN = 2x + 72°

We need to give the reasons in the steps of finding the value of x.

For this we have to know the following properties :

Linear pairs: Adjacent angles which are supplementary.

Subtraction property of equality : We can subtract a number or expression in both sides of an equation.

i.e. a = b ⇒ a + c = b + c

Exterior angle theorem : exterior angle formed by extending the side of a triangle is equal to the sum of its non-adjacent angles.

Thus, the steps of finding value of x are as follow,

1. m∠KLP+m∠PLM = 180°       ( linear pairs )

2. 3x +m∠PLM = 180°              ( Substitution)

3. m∠PLM = 180° - 3x              ( Subtraction property of equality)

4. m∠PMN=m∠P+m∠PLM      ( Exterior angle theorem )

5. 2x + 72° = x + 180° - 3x        ( Substitution)

6. 2x + 72° = 180° - 2x              ( Solving )

   2x = 180° - 2x - 72°  

   2x + 2x = 108°

   4x = 108°

   x   = 27°

How do you round to 630 to the nearest hundred

Answers

Answer: Here we will tell you what 630 is rounded to the nearest hundred and also show you what rules we used to get to the answer.

Remember, we did not necessarily round up or down, but to the hundred that is nearest to 630.

First, 630 rounded to the nearest hundred is: 600

When rounding to the nearest hundred, like we did with 630 above, we use the following rules:

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Step-by-step explanation:

Rounding 630 to the nearest hundred results in 600.

To round the number 630 to the nearest hundred, consider the tens digit of the number.

In this case, the tens digit is 3.

If the tens digit is 5 or greater, you round up to the next hundred.

If the tens digit is 4 or less, you round down to the current hundred.

Since the tens digit in 630 is 3, which is less than 5, you round down.

Therefore, rounding 630 to the nearest hundred results in 600.

Answer:

y = -6x + 31

Step-by-step explanation:

In order for us to make this an equation of the form y = mx + b we have to find the slope.

The formula for slope is rise/ run. The rise is 6 and the run is -1.

So, the slope is 6/-1 or -6.

Our equation is now: y = -6x + b

Substituting 4,7 into the equation we get 7 = -24 + b

So, b = 31.

B. HOW MUCH INFORMATION COULD BE TRANSMITTED IN 30,000 PACKETS

Answers

Answer:

A. It would be needed 20 packets to transmit 30,000 bytes of information.

B. 45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Size of each packet of information = 1,500 bytes

Number of packets = P

Number of bytes of information = B

2. Let's answer the questions:

A. How many packets would be needed to transmit 30,000 bytes of information?

P = 30,000 ÷ 1,500

P = 20

It would be needed 20 packets to transmit 30,000 bytes of information

B. How much information could be transmitted in 30,000 packets?

B = 30,000 * 1,500

B = 45'000,000

45'000,000 (45 million) of bytes could be transmitted in 30,000 packets.

Cousin Hector drove 1,851 miles to the reunion. He lives in Mexico and drove 747 miles through that country to the United States border. How many miles did he drive in the United States?

Answers

Answer:

1104 miles

Step-by-step explanation:

Say he lives in a place in Mexico which is at a distance of a miles from the Mexico-America border point and the reunion is at b miles from the same border point, in America.

So the total distance travelled is ( a + b ) miles

( this is just sum of distance travelled in Mexico + that in America )

Given , a=747 and a+b=1851

that implies:

747 + b = 1851

So, b = 1104 miles.

Therefore he has travelled 1104 miles in America,

Use Pascal’s Triangle to determine the third term of the expansion of (x + 3)4.

Answers

Answer:

In the Pascal Expansion of [tex](x+3)^4[/tex] the third term is [tex]54x^2[/tex].

Step-by-step explanation:

Here, the given expression is given as [tex](x+3)^4[/tex]

Now, by the PASCAL'S TRIANGLE EXPANSION:

[tex](a + b)^4 = 1(a)^4 + 4(a)^3b + 6(a)^2b^2 + 4(a)b^3 + 1b^4\\= 1 + 4b + 6a^2 + 4b^3 + b^4.[/tex]

Substituting a  = x and b = 3, we get:

[tex](x + 3)^4 = 1(x)^4 + 4(x)^3(3) + 6(x)^2(3)^2 + 4(x)(3)^3 + 1(3)^4\\= x^4 + 12x^3 + 54x^2  + 108x+ 81[/tex]

In the given expansion, the third term is [tex]54x^2[/tex].

Hence, in the Pascal Expansion of [tex](x+3)^4[/tex] the third term is [tex]54x^2[/tex].

Final answer:

The third term is 6 times x squared times 3 squared, which simplifies to 54x².

Explanation:

To use Pascal's Triangle to determine the third term of the expansion of (x + 3)⁴, we first need to look at the row of Pascal's Triangle that corresponds to the exponent 4. This is the fifth row if we start counting from 0 and it reads 1, 4, 6, 4, 1. We use these coefficients for each term of the expansion, which follows the pattern (a + b)ⁿ = C(n,0)*aⁿ + C(n,1)*a⁽ⁿ⁻¹⁾b + C(n,2)*a⁽ⁿ⁻²⁾b² + ... + C(n,n)*bⁿ, where C(n,k) is the binomial coefficient from Pascal's Triangle.

So, the third term in the expansion is given by the third coefficient (counting from 0) from the row, which is 6, multiplied by x raised to power 4 - 2 times 3 squared. Therefore, the third term is 6x²·3², which simplifies to 54x².

For setting up a control chart to manage the irregularities (e.g., loose threads and tears), the following data were collected froma sample provided by the supplier.Sample: 1 2 3 4 5 6 7 8 9 10Irregularities: 3 5 2 6 5 4 6 3 4 5(a) Using these data, set up a c-chart with z = 2.(b) Suppose the next five rolls from the supplier had three, two, five, three, and seven irregularitiies. Is the supplier process under control? A 15 kg object starts for rest and is pushed across a frictionless surface e with a force of 30 N for 4 seconds Calculate the final momentum Jeff has 4 red pens and 2 blue pens in his backpack. He also has 1 yellow highlighter and 4 green highlighters in hisbackpack. If he reaches into his backpack and grabs one pen and one highlighter without looking, what is the probabilitythat he will grab a blue pen and a yellow highlighter? A piece of taffy slams into and sticks to an identical piece of taffy at rest. The momentum of the combined pieces after the collision is the same as before the collision, but this is not true of the kinetic energy, which partly degrades into heat. What percentage of the kinetic energy becomes heat?A) 25% B) 0% C) 75% D) 50% E) need more information. science homework plz this is 2 grades for some reason Why are groups 1 and 2 referred to as the s-block of the periodic table
