What is the answer and how did you find that?

We can determine the age by dividing the total number of half-lives by the half-life decay constant of the parent atom (again, this value is determined in a laboratory).

The amount of time needed for a quantity (of substance) to decrease to half of its initial value is known as the half-life (symbol t12).

In nuclear physics, the phrase is frequently used to indicate how rapidly unstable atoms decay radioactively or how long stable atoms last.

By dividing the total number of half-lives by the parent atom's half-life decay constant, we may compute the age (again, this value is determined in a laboratory).

The phrase is also used more broadly to describe any kind of exponential decay (or, very infrequently, nonexponential decay).

The biological half-life of medications and other compounds in the human body, for instance, is a term used in the medical sciences.

Half-opposite of life's exponential growth is time's doubling.

Therefore, we can determine the age by dividing the total number of half-lives by the half-life decay constant of the parent atom (again, this value is determined in a laboratory).

Answer: f(6) = 3

Step-by-step explanation:

If you divide any polynomial h(x) by a linear function (it is to the 1st power) l(x), then the remainder of h(x) when divided by l(x) must be the value of h(x) where x is when l(x) = 0, or the x-intercept.

For example,

x - 6 = 0, and its x-intercept is 6. Therefore, if you do f(6), the remainder will be its output.  

The probability that the student competed in Rhythm given they had competed in Smooth or Standard: P(Rhythm |Smooth or Standard) or P ( A/( B or C)) is 0.6613 = 66.13%.

We have, A survey was conducted at a local ballroom dance studio asking students with three dance categories. The above Venn diagram shows the number of students in these three categories of dance.

Total number of students in all dance categories n(A or B or C) = 5 + 6 + 8 + 12 + 14 + 15 + 10 + 4

= 74

let us consider the events

A : students in Rhythm dance category

B : students in Standard dance category

C : students in Smooth dance category

Using the conditional probability,

Probability that student has competed in Rhythm and they have competed in Smooth, P(Rhythm/ smooth) = P(A/C) = P(A and C)/P(C)

= (12+14)/74 = 26/74 = 0.703

but we have to calculate probability that the student competed in Rhythm given they had competed in Smooth or Standard, P(Rhythm/Smooth or Standard) = P(Rhythm and (Smooth or Standard))/P(Smooth or Standard)

i.e., P( A/(B or C) )= P(A and (B or C))/P(B or C)

n(B or C) = n(B) + n(C) - n( B and C)

=> n(B or C) = 14 + 5 + 10 + 15 + 12 + 14 + 5 + 6 - 5 - 14 = 62

Now, P(B or C) =n(B or C)/n(A or B or C)

=> P(B or C) = 62/74 = 0.703 = 70.3%

P(A and (B or C)) = n(A and (B or C))/n(A or B or C)

n(A and (B or C)) = n(A) + n(B or C) - n(A or B or C)

= 12 + 14 + 15 + 8 + 62 - 70 +4 = 41

P(A and (B or C)) = 37/74

So, P( A/(B or C) )= P(A and (B or C))/P(B or C)

=> P( A/(B or C) )= 41/74/62/74 = 41/62

= 0.6613 = 66.13%

Hence, the required probability is 66.13%.

Taking into account the rule of three, the vehicle cover a distance of 60 km in 45 minute.

The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three must be applied as follow, being a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: x= (c×b)÷a

You can apply the following rule of three: if the vehicle travels 80 km in 60 minutes, in 45 minutes it travels how much distance?

60 minutes ⇒ 80 km

45 minutes ⇒ distance

So:

distance= (45 minutes× 80 km)÷ 60 minutes

Solving:

distance= 60 km

In summary, the vehicle travel 60 km in 45 minute.

Our Median will be 37 when the Mode is 15 and the Mean is 48.

Relationship between Mean Median and Mode?

An empirically established link exists between the mean, median, and mode in statistics. The average difference between the mean and the mode is three times greater than the difference between the mean and the median, according to observations of innumerable data sets. The equation for this relationship is:

Mode - Mean = 3*(Mean – Median).

on solving this we get:

Mode = 3 * Median - 2 * Mean

In our question, it is given that the Mode is 15 and the Mean is 48 and we have to calculate the Median.

Putting these values in our formula, we get:

15 = 3 * Median - 2 * 48

3 * Median = 15 + 96

Median = 111/3 = 37.

Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).

From the information given, the equation is written thus:

a + b / a - b = 5 / 3

Cross multiply

5(a - b) = 3 (a + b)

5a - 5b = 3a + 3b

Collect the like terms

5a - 3a = 3b + 5b

2a = 8b

Divide

a = 8b / 2

a = 4b

Therefore (a + b) / a will be:

A graph is a visual representation of data or information, typically plotted on an x-axis and a y-axis. A graph is said to be infinite when it has an infinite number of points that could be connected, or an infinite number of lines, curves, or shapes that could be drawn on the graph. For example, a line graph without an end point is considered infinite because it theoretically continues forever. Similarly, a circle graph with no beginning or end point could also be considered infinite. Other types of graphs that can be considered infinite include bar graphs, area graphs, scatter plots, and pie charts. When determining whether a graph is infinite, it is important to consider the purpose of the graph and its data. If the graph is meant to represent an infinite set of data points, then it can be considered infinite. Likewise, if the graph is meant to represent a function that goes on forever, then it should also be considered infinite.

Answer: -1324 spaces left in the car park.

Step-by-step explanation: There are 8 floors in the multi-storey car park and each floor has 5 rows of 20 cars, so there are 8 * 5 = <<85=40>>40 rows in the car park in total.

If each row has space for 20 cars, then the total number of parking spaces in the car park is 40 * 20 = <<4020=800>>800.

If 2124 cars have already parked, then there are 800 - 2124 = <<800-2124=-1324>>-1324 spaces left in the car park.

It is not possible for the car park to have negative spaces, so the answer must be 0. Therefore, if 2124 cars have already parked, there are 0 spaces left in the car park.

To find the number of integers less than 305 that are divisible by 3, we can divide 305 by 3 and round down to the nearest integer. This gives us 101. However, we need to subtract 1 to exclude the number 305 itself, so there are 100 numbers less than 305 that are divisible by 3.
