For the given situation, we can clearly say that the change in one quantity will cause a change in the second quantity as well.

Correlation is a relationship between the values ​​of two variables. A scatter plot is a useful tool for displaying data about two variables as a series of points in the x and y plane and determining whether there is a correlation between the variables.

Causality means that one event causes another. Causality can only be determined by well-designed experiments. In such experiments, similar groups receive different treatments, and the results of each group are examined.

From the above information, we concluded that a person's age and the number of cassette tapes he/she owns are correlated more he lives the more he buys the cassette tapes. So we can make relation from this,

Person's Age ∝ Number of Cassette

This clearly states that by increasing/changing one quantity we will increase/change the other quantity as well.

Similarly, now that they have a direct relation if we decrease the Age of the person, the number of Cassette's will also decrease. A positive correlation we can call it.

Step-by-step explanation:

You must determine the least common multiple of the three in order to respond to this. 8:28 pm will be the moment when all three lights flash simultaneously next.

Wat is the LCM of 2, 3.5, and 4 in whole numbers?

Work with 3.5 now:

3.5 * 1 Equals 3.5 (no, 2 and 4 don't split into 3.5 in an equal manner)

3.5 * 2 = 7 (no, same excuse)

3.5 * 3 = 10.5 (nope) (nope)

3.5 * 4 = 14 (nope) (nope)

3.5 * 5 = 17.5 (nope) (nope)

3.5 * 6 = 21 (nope) (nope)

3.5 * 7 = 24.5 (nope) (nope)

3.5 * 8 = 28 (yes, as 2 and 4 are factors of 28) (yep, since 2 and 4 are factors of 28)

Therefore, 8:28 pm will be the moment when all three lights flash simultaneously next.

D = M/12 + N/4 represents the relationship between Elena's distance in miles, D, and her biking speed.

Speed = distance/ time

Here, we are given that Elena bikes 20 minutes each day for exercise. She bikes at a constant speed of M miles per hour for the first 5 minutes, then at N miles per hour for the last 15 minutes.

Therefore, distance covered by her in the first 5 minutes = speed x time

time = 5 minutes = 5/60 hours

= 1/12 hours

Thus, distance = M(1/12)

= M/12

Now, similarly, distance covered by her in the last 15 minutes = N(15/60)

=N/4

Thus, the total distance in miles, D, covered by her in the last 15 minutes = N(15/60)

= N/4

Thus, the total distance in miles, D, covered by her is D = M/12 + N/4

The x-value of the solution of x + y = 7 , 3x - 2y = 11, is equal to 5.

The given equations are linear equations in two variables since there are two unknown variables present in these equations.

Considering equation number one to be, x + y = 7

and equation number two to be, 3x - 2y = 11

By rearranging the first equation, the value of x can be considered to be:

x + y = 7

x = 7 - y

Adding this value of x in the second equation for the solution of y;

3 (7 - y) - 2y = 11

21 - 3y - 2y = 11

Rearranging,

21 - 11 = 3y + 2y

10 = 5y

y = 10 ÷ 5

y = 2

By adding this value of y to the first equation, the value of x can be found as follows,

x + y = 7

As y = 2

x + 2 = 7

x = 7 - 2

x = 5

Hence, the value of x is calculated to be 5.

Have a great day!

The value of A in the 4-digit number is 5.

What is the value of A?

Given the information provided in the question, the 4-digit number is a multiple of 15. A multiple of a number is the product of an integer and that number.

The multiple of a number is divisible by that number. For example, a multiple of 2 is 20. This is because 2 multiplied by 10 is equal to 20 and 20 is divisible by 2 to yield a value of 10.

The multiplies of 15 either have a unit value of 5 or 0.

If A is 5, the number becomes 3555.

3555 / 15 = 237

If A is 0, the number becomes 3050

3050 / 15 = 203.333

Thus, the value of A is 5 because 3555 is divisible by 15.

Finding the equation of the parabola, it is found that the height of the diving board is of 24 feet.

What is the equation of a parabola given it’s vertex?

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

From the maximum height, it is found that the vertex is at (1,25), hence:

h = 1, k = 25.

Hence:

y = a(x - 1)² + 25.

You hit the water 6 feet from the diving board, hence y(6) = 0, meaning that we use it to find a as follows:

0 = a(6 - 1)² + 25

25a = -25.

a = -1.

Hence:

y = -(x - 1)² + 25.

The height of the diving board is y(0), hence:

Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2
