For the next math competition, Mr. Johnson would like to arrange all of the students who
rows with only girls or only boys in each row.
What is the greatest number of students that can be in each row​

Answer:

4 2/4

Step-by-step explanation:

3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4

To find the total weight of the coins Trey picked up, multiply the weight of one coin by the number of coins. The total weight is 9/2 ounces or 4.5 ounces in decimal form.

To find the total weight of the coins Trey picked up, we need to multiply the weight of one coin by the number of coins picked up. The weight of one coin is 3/4 ounces, and Trey picked up 6 of these coins. To multiply a fraction by a whole number, we multiply the numerator (top number) of the fraction by the whole number. So, the total weight of the coins Trey picked up is (3/4) * 6 = 18/4 ounces.

Next, we simplify the fraction to its simplest form. To do this, we find the greatest common divisor (GCD) of the numerator and denominator, and divide both by the GCD. In this case, the GCD of 18 and 4 is 2. Dividing both the numerator and denominator by 2, we get 18/4 = 9/2. So, the total weight of the coins Trey picked up is 9/2 ounces or 4.5 ounces in decimal form.

Answer:

Yes they are independent, because P(girl) ≈ 0.42 and P(girl l plays a sport) ≈ 0.42

Step-by-step explanation:

A.P.E.X

Yes, being a girl and playing a sport are independent events as P(girl) = P(girl plays a sport) = 0.4

The term probability refers to the likelihood of an event occurring. It is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

Given that;

We have been given a table that shows the results broken down by gender.

            Play sports         Do not play sports       Total

Boy            105                            75                        180

Girl             70                             50                        120

Total          175                            125                       300

Here, Formula for probability of independent events:

"If A and B are independent events then, P(A∩B) = P(A).P(B)"

And, Formula of the probability of an event A is:

⇒ P(A) = n(A)/n(S)

where,  n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.

Now, Using the definition of probability:

⇒ P(girl)  = Number of girls/ Number of students

⇒ P(girl) = 120/300

⇒ P(girl) = 0.4      .....(1)

And, we find the probability of girls that play a sport.

Using the definition of probability:

P(girl plays a sport) = Number of girls who plays a sport/ number of students who plays a sport

= 70/ 175

= 0.4    ...(2)

From (1) and (2),

P(girl) = P(girl plays a sport)

Thus, Being a girl and playing a sport are Independent events.

Surface area (SA) of the cylinder is computed as follows:

SA = π*d*h + π*d²/2

Replacing with data:

SA = π*8*18 + π*8²/2

SA = 144π + 32π

Answer:

10. 4.8%

11. 5.67%

12. 30.39%

Step-by-step explanation:

The total number of coins is 5 + 7 + 9 = 21 coins

The probability of selecting two pennies without replacemente is:

First penny: 5 possibilities over 21 coins: 5/21

Second penny: 4 possibility over 20 coins: 4/20

P(selecting 2 pennies) = (5/21) * (4/20) = 1/21 = 0.048 = 4.8%

With replacement, we have:

First penny: 5 possibilities over 21 coins: 5/21

Second penny: 5 possibilities over 21 coins: 5/21

P(selecting 2 pennies) = (2/21) * (2/21) = 25/441 = 0.0567 = 5.67%

The cases for selecting the same coin are:

First penny: 5 possibilities over 21 coins: 5/21

Second penny: 4 possibilities over 20 coins: 4/20

P(selecting 2 pennies) = (5/21) * (4/20) = 20/420

First nickel: 7 possibilities over 21 coins: 7/21

Second nickel: 6 possibilities over 20 coins: 6/21

P(selecting 2 nickels) = (7/21) * (6/21) = 42/441

First dime: 9 possibilities over 21 coins: 9/21

Second dime: 8 possibilities over 20 coins: 8/21

P(selecting 2 dimes) = (9/21) * (8/21) = 72/441

P(selecting the same coin twice) = P(selecting 2 pennies) + P(selecting 2 nickels) + P(selecting 2 dimes) = (20+42+72)/441 = 0.3039 = 30.39%

The probabilities for picking 2 pennies either with or without replacement from a total of 21 coins is calculated. With no replacement, the chance is approximately 4.76%, while with replacement, it is approximately 5.67%. It's impossible to choose the same coin twice without replacement.

The total number of coins is 5 pennies + 7 nickels + 9 dimes = 21 coins. We are asked to calculate the probability of selecting 2 specific coins from these total coins.

10. P(selecting 2 pennies), if no replacement occurs:
Since no replacement is occurring, we first select one penny out of 5, then another penny out of the remaining 4. That constitutes 5/21 * 4/20 = 0.0476, or 4.76% probability of selecting two pennies without replacement.

11. P(selecting 2 pennies), if replacement occurs:
Since replacement is possible in this scenario, even after choosing a penny, we still have 5 pennies left. Hence, the probability of selecting a penny twice is (5/21) * (5/21) = 0.0567, or approximately 5.67%.

12. P(selecting the same coin twice), if no replacement occurs:
If no replacement occurs, it's impossible to choose the exact same coin twice because once a coin is chosen, it is removed from consideration. Therefore, the probability here is 0.

From the question, we have the following parameters that can be used in our computation:

x + y = 6

This can be expressed as

y = 6 - x

The missing y values are at x = 4, 8 and x = 12

Substitute the known values in the above equation, so, we have the following representation

y = 6 - 4 = 2

y = 6 - 8 = -2

y = 6 - 12 = -4

The infinite sequence can be written as -2, 4, -6, 8 ..... with common difference -2.

In a geometric sequence, the ratio of two consecutive terms are always equal.

The general expression for the nth term is given as aₙ = a₁ × rⁿ⁻¹ .

The sum of n terms for this sequence is given as Sₙ = (rⁿ - 1)/(r - 1).

The expression for the general term for the given sequence is as below,

aₙ = (-1)ⁿ2n

The various terms can be written for different values of n as follows,

⇒ a₁ = (-1)¹ × 2 × 1 = -2

⇒ a₂ = (-1)² × 2 × 2 = 4

⇒ a₃ = (-1)³ × 2 × 3 = -6

⇒ a₄ = (-1)⁴ × 2 × 4 = 8

The Russian submarine is deeper since -205 meters is a greater depth than -200 meters when comparing negative values.

To compare the depths of the two submarines, we need to consider the numerical value of their depths. When we look at depths, the larger the negative number, the deeper the location. In this case, a depth of -200 meters means the French submarine is closer to the surface than a depth of -205 meters.

Therefore, the Russian submarine is deeper because -205 is lower than -200 when considering depths below sea level.

I just took the quiz on edge

Answer:

20% increase

Step-by-step explanation:

1- New number-original number

2- number increased divided by new number then multiply by 100

15-12= 3

3 divided by 15= 0.2

0.2 times 100= 20%

If an original quantity is 12, and the new quantity is 15, then the percentage increase is 25%.

Given that, an original quantity is 12, and the new quantity is 15.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here,

Percentage increase = (New quantity - Original quantity)/Original quantity ×100

= (15-12)/12 ×100

= 3/12 ×100

= 0.25×100

= 25%

Therefore, if an original quantity is 12, and the new quantity is 15, then the percentage increase is 25%.
