What is meant by the word function?A science called mathematics studies numbers, their variants, mathematical and the local structures, shapes, and both their existing and projected places. The relationship between a group of inputs, which each have a corresponding output, is described by a function variable . A function is a collection of inputs that together produce a single, recognisable output by each input.
Here,
Given :
=> 2x = 15x²
=> 2 = 15x
=> x =15/2
=> -6x =8x²
=> -6 = 8x
=>x = -4/3
thus , x =15/2 and x=-4/3

suppose you have 5 blue marbles and 5 red marbles in a bag. you pull out one marble, which may be blue or red and do not replace it. what is the probability that the second marble will be red?
Answers
Therefore , the solution of the given problem of probability comes out to be probability that the second marble will be red = 0.5.
What exactly does the probability process entail?Calculating the likelihood that a statement is true or that an event will occur is the focus of the branch of mathematics known as probability theory. Any number from 0 to 1, where 1 represents certainty and 0 normally represents possibility, may be used to represent chance. The likelihood that a particular event will occur is depicted in a probability diagram. Probabilities can be represented by the numbers 0 and 1, percentages with a range of 0% to 100%, and a small number of extra characters. the proportion of incidents that occurred among a set of equally likely possibilities out of all potential outcomes
Here,
(p = 5/10) First Blue
Blue II (p = 4/9)
Red 2 (p = 5/9)
Primary Red (p = 5/10)
Blue II (p = 5/9)
Fourth Red (p = 4/9)
Interestingly, if you observe the first marble and then put it back in, the outcome will remain the same (sampling with replacement). The second draw doesn't depend on the first.
=> Pr(B, R) = Pr(B)*Pr(R)
=> (5/10), (5/10), (1/2), (1/2), and 1/4.
and
=>Pr(R, R) = Pr(R)*Pr(R)
=> (5/10), (5/10), and (1/2).
(1/2) = 1/4
Pr
R, R, or (B, R) = (1/4) + (1/4) = 1/2
Therefore , the solution of the given problem of probability comes out to be probability that the second marble will be red = 0.5.

Step-by-step explanation:
Answer:
No. Divide the group of 12 small blue squares by small groups of 4 small blue squares, and you get 3, not 0.03.
Step-by-step explanation:
6.
The large square is divided into small squares. There are 10 small squares on each side of the large square. Since 10 × 10 = 100, the large square is divided into 100 small squares.
The large square is 1 unit.
Since the large square, 1 unit, is divided into 100 small squares, then each small square represents 1/100 of a unit, or 0.01 unit as a decimal.
There are 12 small squares shaded blued.
Each small square is 0.01 unit, so 12 squares represent 12 × 0.01 = 0.12.
The group of 12 small squares is divided into 3 smaller groups of 4 small squares each. Each group of 4 small squares represents 4 × 0.01, or 0.04.
Now we are asked what 0.12 ÷ 0.04 equals.
Look at the figure. The 0.12 of the entire blue shading makes up 3 groups of 0.04 size, so 0.12 ÷ 0.04 = 3.
The division 0.12 ÷ 0.04 is the same as asking how many groups of 4 small squares can you fit in the group of 12 small squares? The answer is 3.
0.12 ÷ 0.04 = 3
The answer 0.12 ÷ 0.04 = 0.03 is incorrect.
Answer: No. Divide the group of 12 small blue squares by small groups of 4 small blue squares, and you get 3, not 0.03.

a fair die is cast until a 6 appears what is the probability that it must be cast more than 5 times times
Answers
The probability that the fair die must be cast more than 5 times is 0.4315 or 43.15%.
The probability that it must be cast more than five times is the complement of the probability that it will be cast five or less times.
The probability of getting a 6 on the first roll is 1/6, the probability of not getting a 6 on the first roll is 5/6. The probability of getting a 6 on the second roll, given that it was not obtained on the first roll, is 1/6. The probability of getting a 6 on the third roll, given that it was not obtained on the first and second rolls is 1/6 and so on.
The probability of not getting a 6 in five rolls is (5/6)⁵. The probability of getting a 6 on the fifth roll is 1/6. The probability of getting a 6 on the fifth roll or not getting it on the first five rolls is (5/6)⁵ + 1/6.
So the probability of getting a 6 in five rolls or less is (5/6)⁵ + 1/6.
Therefore, the probability of getting a 6 in more than five rolls is 1 - ((5/6)⁵ + 1/6) = 0.4315
So the probability of having to cast the die more than five times to get a 6 is 0.4315 or 43.15%.

The new temperature of a gas will be 324.38k .
The Ideal Gas Equation defines the four gas variables and one constant for a better understanding. The four gas variables are pressure (P), volume (V), number of moles of gas (n), and temperature (T). Lastly, the constant in the equation shown below is R, known as the gas constant.
PV=RT

According to the question,
[tex]V_{1} = 7.3 litres[/tex] , [tex]V_{2} = 7.4 litres, T_{1} = 320k[/tex]
⇒ [tex]\frac{7.3}{7.4} = \frac{320}{T_{2} }[/tex] (substitute the values)

State the minimum monthly income and hourly wage per worker needed to cover monthly expenses for the family in the photo. Then, explain how to calculate the hourly wage based on the monthly income and state the hourly wage. Assume that each full-time worker works four 40 hour work weeks per month and each part-time worker works four 40 hour weeks per month.
Answers
Full-time worker minimum monthly income = US$ 7,846.40
Part-time worker minimum monthly income = US$ 7,846.40
Full-time worker hourly wage = US$ 49.04
Part-time worker hourly wage = US$ 98.08
Explanation:1.Review the information
Monthly costs of a 2-adult and 3-children family in the Modesto metro area = US$ 5841
Full-time worker = 4 weeks of 40-hour per month
Part-time worker = 2 weeks of 40-hour per month
2. Let's calculate the minimum monthly income and hourly wage per worker
Full-time worker hourly wage = Monthly costs/160
Part-time worker hourly wage = Monthly costs/80
Full-time worker hourly wage = 5841/160
Part-time worker hourly wage = 5841/80
Full-time worker hourly wage = US$ 36.5
Part-time worker hourly wage = US$ 73
Full-time worker minimum monthly income = Hourly wage * 160
Part-time worker minimum monthly income = Hourly wage * 80
Full-time worker minimum monthly income = US$ 5840
Part-time worker minimum monthly income = US$ 5840

Arnold is testing a new train locomotive on circular rail track with a radius of 0. 9 kilometers. How many times around the track does Arnold need to run the train to cover a distance of at least 50 kilometers?
Answers
So, Arnold needs to run the train 9 times around the track to cover a distance of at least 50 kilometers.
We know that the radius of the circular rail track is 0.9 kilometers, so the circumference of the track can be found using the formula C = 2πr, where C is the circumference and r is the radius of the circle.
C = 2 * 3.14 * 0.9 = 5.652 km
To find out how many times Arnold needs to run the train around the track to cover a distance of at least 50 kilometers, we need to divide 50 by the circumference of the track.
50 km / 5.652 km = 8.9
Arnold needs to run the train around the track approximately 8.9 times to cover a distance of at least 50 kilometers.
To be more precise, we can round up the result, so Arnold needs to run the train 9 times around the track to cover a distance of at least 50 kilometers.

where:
n represents the total number of items; and
r represents the number of items being chosen at a time.
