Step-by-step explanation:

Answer: y = (x + 3)2 − 4 is the equation of the function.

Step-by-step explanation:

The net change in the value of the function between x = 1 and x = 6 is 30.

To find the net change in the value of the function between the inputs of 1 and 6, we need to find the difference between the output values of the function at x = 1 and x = 6, and then take the absolute value of that difference.

First, we can find the output value of the function at x = 1:

f(1) = 6(1) - 5 = 1

Next, we can find the output value of the function at x = 6:

f(6) = 6(6) - 5 = 31

The net change in the value of the function between x = 1 and x = 6 is the absolute value of the difference between these two output values:

|f(6) - f(1)| = |31 - 1| = 30

Therefore, the net change in the value of the function between x = 1 and x = 6 is 30.

I believe that is the correct answer! Hope this is helpful! :)

The probability that the risk level is 0 irrespective of the applicant's marital status is 0.6.

The given information states that 60% of loan applicants were classified as low risk (risk level 0), and 40% were classified as high risk (risk level 1). Therefore, the probability of an applicant being classified as low risk is 0.6, and the probability of being classified as high risk is 0.4.

The question asks for the probability that an applicant is classified as low risk regardless of their marital status. This means that the probability is not affected by whether the applicant is married or not.

Since we know that the probability of an applicant being classified as low risk is 0.6, and this probability is not affected by their marital status, the answer to the question is simply 0.6.

In other words, regardless of whether an applicant is married or not, there is a 60% chance that they will be classified as low risk.

Answer:

\(P(W') = \frac{6}{n+6}\)

Step-by-step explanation:

Let P(W) represents the probability that Paul wins

Let P(W') represents the probability that Paul does not win

Given

\(P(W) = \frac{n}{n+6}\)

Required

\(P(W')\)

In probability, the sum of opposite probability equals 1;

This implies that

\(P(W) + P(W') = 1\)

Substitute \(P(W) = \frac{n}{n+6}\) in the above equation

\(P(W) + P(W') = 1\) becomes

\(\frac{n}{n+6}+ P(W') = 1\)

Subtract \(\frac{n}{n+6}\) from both sides

\(\frac{n}{n+6} - \frac{n}{n+6} + P(W') = 1 - \frac{n}{n+6}\)

\(P(W') = 1 - \frac{n}{n+6}\)

Solve fraction (start by taking the LCM)

\(P(W') = \frac{n + 6 - n}{n+6}\)

\(P(W') = \frac{n - n + 6}{n+6}\)

\(P(W') = \frac{6}{n+6}\)

Hence, the probability that Paul doesn't win is \(P(W') = \frac{6}{n+6}\)

The smallest number of people such that probability for at least 2 of them were born on April 1 exceeds "1/2" is 115 persons.

At least 2 out of the "n" people born on April 1, it means that either all "n" people are not born on "April-1" or exactly 1 person is born on "April-1", So, P(X) ⇒ 1 - P(Y) - P(Z)

where P(Y) denotes probability that none are born on "April-1" and P(Z) denotes the probability that exactly one is born on "April-1",

P(Y) can be expressed as = 364ⁿ/365ⁿ,

So, P(Z) = n × 364ⁿ⁻¹/365ⁿ,

and , P(X) = 1 - P(0) - P(1)

P(X) = 1 - 364ⁿ⁻¹/365ⁿ × (364 - n),

Now, using the hit and trial method,

We get,

P(3) ⇒ 0.016

P(50) ⇒ 0.24

P(120) ⇒ 0.517

P(119) ⇒ 0.514

P(115) ⇒ 0.502

P(114) ⇒ 0.497

We see that probability exceeds (1/2) = 0.5, when x=115, that is 115 persons,

Therefore, the required number of persons are 115.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A cylindrical fish tank at the zoo has a capacity of 7252 cubic feet.

Now, We know that;

Volume of a cylinder = π × radius² x height

Here, Radius is 16 feet.

Hence, We get;

Volume of a cylinder = π × radius² x height

7252 = 3.14 × 16² × h

⇒ 7252 = 803.84 h

⇒ h = 7252 / 803.84

⇒ h = 9.02 feet

Step-by-step explanation:

The 210 feet diameter of the ferris wheel rotated 45° gives;

The amount by which the height of the seat changes is the option;

\( \Delta y = \frac{210 \cdot \sqrt{2}}{2} \: ft \)

Given parameters;

Diameter of the wheel, D = 210 feet

Angle of rotation of the wheel = 45°

Required;

The measure by which the height changes.

Solution;

The equation of a Ferris wheel can be represented as follows;

y = A•sin(B•(x - c)) + D

Change in height, ∆y, is found as follows;

∆y = A•sin(t1) + D - A•sin(t2) + D

∆y = A•(sin(t1) - sin(t2))

Where;

t1 = 0

t2 = 45°

A = The radius = 210 feet

Therefore;

∆y = 210×2×(sin((45+0)/2)° × cos((45-0)/2)°)

∆y = 210×2×(sin(22.5)° × cos(22.5)°)

∆y = 210×sin(2×22.5)° = 210×sin(45)°

The amount by which the height of the seat changes is therefore;

\( \Delta y = \frac{210 \cdot \sqrt{2}}{2} \: ft \)

The correct option is therefore;
