a) the corresponding standardized value (z) for x = 4.1 is approximately 1.39.

b) The area under the standard normal probability density function from negative infinity to z is interpreted as the probability that the random variable is less than or equal to z.

a) To calculate the standardized value (z) for the point x = 4.1, we can use the formula:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation.

In this case, x = 4.1, μ = 0.33, and σ = 2.69. Plugging these values into the formula:

z = (4.1 - 0.33) / 2.69

z ≈ 1.39

So, the corresponding standardized value (z) for x = 4.1 is approximately 1.39.

b) The area under the standard normal probability density function from negative infinity to z is interpreted as the probability that the random variable is less than or equal to z.

Type fish A are 8 inches long and Type B fish are 7 inches long.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific values in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Marta's aquarium holds 38 gallons of water

and Hank's aquarium hold 52 gallons of water.

let length of fish A be x

and, the length of type B be y.

So, 3x+ 2y = 38

and, 3x+ 4y = 52

Solving above equation

2y = 52-38

2y = 14

y=7

and, 3x+ 2(7) = 38

3x = 38-14

3x= 24

x= 24/3

x= 8

Hence, Type fish A are 8 inches long and Type B fish are 7 inches long.

Bayes' theorem is used to connect the probability of a person's DNA profile appearing in a sample with the possibility of that person being guilty.

Likelihood ratio (LR) is the ratio of the possibility of the evidence given the accused's guilt divided by the probability of the evidence given the accused's innocence. LR is a frequent tool used by experts to estimate the likelihood of a suspect being the source of a DNA sample. The likelihood ratio can be used to assess the probability of a given event. For example, it may be used to determine the likelihood of a crime suspect's DNA profile appearing in a sample.

It is essential to know the likelihood ratio of the first, second, third, fourth, and fifth occurrence of the same diagnosis for the same person to make an accurate assessment of this probability. This may be accomplished by calculating separate likelihood ratios for each occurrence.

In any likelihood ratio calculation, Bayes' theorem is used to link the probability of an individual's DNA profile appearing in a sample with the possibility of that person being guilty. This theorem helps to account for the possibility of coincidental matches.

The value of the likelihood ratio is determined by the strength of the DNA evidence in the case. When there is a higher probability of a match, the ratio will be higher. The value of the LR should be sufficiently large to establish the probability of the evidence given the suspect's guilt or innocence. Typically, an LR of more than 100 is considered a strong match.

The likelihood ratio for the first occurrence is calculated by dividing the likelihood of the evidence given the accused's guilt by the likelihood of the evidence given the accused's innocence. The same calculation is repeated for each additional occurrence. The sum of the likelihood ratios for all occurrences is used to compute the overall likelihood ratio for the case.

To conclude, the separate likelihood ratios for the first, second, third, fourth, and fifth occurrences of the same diagnosis for the same person can be calculated to assess the probability of a given event. Bayes' theorem is used to connect the probability of a person's DNA profile appearing in a sample with the possibility of that person being guilty. An LR of more than 100 is considered a strong match.

After the 10th iteration, the estimated value of the root obtained by the bisection method is approximately 0.517. Option B

To solve the equation cos(x) - x * e = 0 in the interval [0, 1] using the bisection method, we start by checking the function values at the endpoints of the interval.

For x = 0:

cos(0) - 0 * e = 1 - 0 = 1

For x = 1:

cos(1) - 1 * e ≈ 0.54 - 2.72 ≈ -2.18

Since the function values at the endpoints have opposite signs, we can apply the bisection method to find the root within the interval.

The bisection method involves repeatedly dividing the interval in half and checking the function value at the midpoint until a sufficiently accurate approximation is obtained. In this case, we will perform 10 iterations.

After the 10th iteration, the estimated value of the root obtained by the bisection method is approximately 0.517.

The shortest path to take is \(20\sqrt{3}\ cm\) or \(34.64\ cm\)

Step-by-step explanation:

This question requires an attachment (See attachment 1 for question)

Given

Cube Dimension: 20cm * 20cm

Required

Shortest path from A to B

For proper explanation, I'll support my answer with an additional attachment (See attachment 2)

The shortest path from A to B is Line labeled 2

But first, the length of line labeled 1 has to be calculated;

This is done as follows;

Since, the cube is 20 cm by 20 cm

\(Line1^2 = 20^2 + 20^2\) (Pythagoras Theorem)

\(Line1^2 = 2(20^2)\)

Take square root of both sides

\(Line1 = \sqrt{2(20)^2}\)

Split square root

\(Line1 = \sqrt{2} * \sqrt{20^2}\)

\(Line1 = \sqrt{2} * 20\)

\(Line1 = 20\sqrt{20}\)

Next is to calculate the length of Line labeled 2

\(Line2^2 = Line1^2 + 20^2\) (Pythagoras Theorem)

Substitute \(Line1 = 20\sqrt{20}\)

\(Line2^2 = (20\sqrt{2})^2 + 20^2\)

Expand the expression

\(Line2^2 = (20\sqrt{2})*(20\sqrt{2}) + 20 * 20\)

\(Line2^2 = 400*2 + 400\)

Factorize

\(Line2^2 = 400(2+1)\)

\(Line2^2 = 400(3)\)

Take square root of both sides

\(Line2 = \sqrt{400(3)}\)

Split square root

\(Line2 = \sqrt{400} * \sqrt{3}\)

\(Line2 = 20 * \sqrt{3}\)

\(Line2 = 20 \sqrt{3}\)

The answer can be left in this form of solve further as follows;

\(Line2 = 20 * 1.73205080757\)

\(Line2 = 34.6410161514\)

\(Line2 = 34.64 cm\) (Approximated)

Hence, the shortest path to take is \(20\sqrt{3}\ cm\) or \(34.64\ cm\)

Answer:

44.72 cm

Step-by-step explanation:

1. This was marked correct by RSM

2. Unfold the cube, so that points A and B and on points diagonal from each other on a 40 cm x 20 cm rectangle. Now draw a line connecting points A to B. That is the hypotenuse of both triangles. Now according to the pythagorean theorem, the hypotenuse is √2000, which is equal to 5√20.

The probability of being dealt 4​, ​5, 6​, 7​, and 8​, not necessarily in the same​ suit is  0.00039.

The cards 4,5,6,7, and 8 are given to us. We must figure out the probability of obtaining these cards in a deal. As we already know, probability equals the number of possible card selection methods divided by the total number of possible card selection methods. The amount of card selection options will therefore be determined initially.

We know that there are four cards of each number, 4, 5, 6, 7 and 8, in a deck of 52 cards. This means that there will be an equal number of possibilities to choose one card from the decks of 4, 5, 6, 7 and 8 when raised to the power of five.

Possible ways= 4^5= 1024

Total selection= C(52,5)= 2598960

Probability of being dealt with  4​, ​5, 6​, 7​, and 8​ is 1024/2598960 which is equal to 0.00039.

The monthly payment that Micaylah gives will be $189.1.

Given that:

Principal, P = $8,500

Rate, r = 0.0325 / 12 = 0.0027

Time, n = 4 x 12 = 48

The formula of monthly payment (MP) will be

\(\rm MP = P \times \dfrac{r(1+r)^n}{(1+r)^n - 1}\\\)

Substitute the values in the above equation, then the monthly payment is calculated as,

MP = $8,500 x 0.0027 x (1 + 0.0027)⁴⁸ / [(1 + 0.0027)⁴⁸ - 1]

MP = $8500 x 0.0027 x (1.1382) / (1.1382 - 1)

MP = $8500 x 0.0027 x (1.1382) / (0.1382)

MP = $8,500 x 0.0027 x 8.2135

MP = $189.1
