The posterior probability of a sensor fault increases as the number of consecutive measurements below 1m increases.

Let P(F) be the prior probability of a sensor fault and P(M|F) be the probability of measurements below 1m given a faulty sensor. Then, the posterior probability of a sensor fault given N consecutive measurements below 1m is given by

P(F|M1 ,M2 ,...,MN )=P(F)P(M1|F)P(M2|F)....P(MN |F)/P(M1 ,M2 ,...,MN )

P(M1 ,M2 ,...,MN ) = P(M1)P(M2)....P(MN) = (1/3)^N

Therefore,

P(F|M1 ,M2 ,...,MN )=P(F)(1/3)^N

For N = 1,2,...,10

P(F|M1 ,M2 ,...,MN ) = 0.01 (1/3)^N

For N = 1, P(F|M1)= 0.01/3

For N = 2, P(F|M1,M2)= 0.01/9

For N = 3, P(F|M1,M2,M3) = 0.01/27

Similarly, for N= 4,5,6,7,8,9,10

P(F|M1,M2,M3,M4,M5,M6,M7,M8,M9,M10) = 0.01/81, 0.01/243, 0.01/729, 0.01/2187, 0.01/6561, 0.01/19683, 0.01/59049 respectively.

here, we have,

from the given figure , we get,

the trapezoid's,

parallel sides are, 9 ft. & 7ft.

height = 3.6 ft.

so, area = ½ (a + b) h,

i.e. A = 28.8 ft^2

Again, area of the triangle is,

area = 1/2 * base * height

         = 1/2 * 7* 2.8

Based on Madison's equation, the y-value is equal to 8.5.

In Mathematics, a function is typically used for uniquely mapping an independent value (input variable or domain) to a dependent value (range or output variable).

In order to use the given function to determine the value of y (y-value), we would have to substitute the values of x (x-value or domain) into the function and then evaluate as follows;

y = 0.5x² + 4

y = 0.5(-3)² + 4

y = 0.5(9) + 4

Total cost of soda and popcorn for 5 people = $6.00 x 5 = $30.00

Yes, two different expressions to calculate the total cost of the soda and popcorn for Tina and her family are:

Expression 1: Total cost of soda = $2.50 x 5 (5 people) = $12.50

Total cost of popcorn = $3.50 x 5 = $17.50

Total cost of soda and popcorn = $12.50 + $17.50 = $30.00

A ratio is a comparison of two or more values. It is a way of expressing the relationship between two or more quantities in the form of a fraction. The numerator of the fraction represents the first quantity and the denominator represents the second quantity. The ratio can be written in the form of a:b, where a and b are the two quantities being compared.

For example, if you have 4 apples and 2 bananas, the ratio of apples to bananas can be expressed as 4:2 or 2:1. This means that for every 2 bananas, there are 4 apples. Ratios can also be used to compare values of different units, for example, miles to kilometers or pounds to kilograms.

Ratios are widely used in many fields, including finance, cooking, construction, and physics, to compare and express the relationship between different quantities. They provide a simple and intuitive way to compare values and help to make sense of complex data.

Answer:

Step-by-step explanation:

1) Completing the square is a good solving option when b is an even number.

2) The discriminant of the quadratic equation y² = x² + 4x + 4 is positive.

What is discriminant?

The discriminant of a polynomial is a number that depends on the coefficients and allows some properties of the roots to be deduced without having to compute them.

1) Completing the square is a good solving option when b is an even number.

Completing the square is a technique used to solve quadratic equations of the form ax² + bx + c = 0 by rewriting the equation as a perfect square. This technique is particularly useful when b is an even number because it makes it easier to recognize the perfect square pattern.

For example, if b = 2, then the equation can be written as ax² + 2x + c = 0. By adding and subtracting the same term, this equation can be rewritten as a(x + 1)² + (c - a) = 0, which is a perfect square. Solving the equation then becomes a matter of finding the square root of the constant term.

If b is an odd number, the equation can still be solved using the completing the square technique, but it may require more steps.

Hence, Completing the square is a good solving option when b is an even number.

2) The discriminant of a quadratic equation of the form ax² + bx + c = 0 is given by b² - 4ac. In this case, a = 1, b = 4, and c = 4, so the discriminant is b² - 4ac = 4² - 4 * 1 * 4 = 16 - 16 = 0.

A positive discriminant means that the equation has two real and distinct roots, a negative discriminant means that the equation has two complex roots, and a zero discriminant means that the equation has one real root (a double root).

Hence, The discriminant of the quadratic equation y² = x² + 4x + 4 is positive.

The two expressions for this situation, with one representing the cost per customer and the other representing the average number of customers are:

Cost: 10 + x

Customer: 16 - 2x

Inequality: 160 - 4x - 2x² ≥ 130.

Based on the information provided, we can logically deduce that the amount of money being charged by Noah per buffet is equal to $10. Also, the total number of customers that chose buffet every hour is equal to 16 customers.

For an increase in the cost of buffet by $1, the average number of customers who selected the buffet would decrease by 2 per hour and the minimum revenue per hour is $130.

Therefore, an expression that represents the cost per customer is given by;

Cost: 10 + x

Additionally, an expression that represents the average number of customers;

Customer: 16 - 2x

Lastly, an inequality that would help Noah make the best pricing decisions is as follows;

Revenue = Cost × Customers

(10 + x) × (16 - 2x) ≥ 130

To determine if the ordered pair (1, 5) is a solution to the system of equations, we substitute the values into the equations and see if they hold true.

25 = 25 (holds true)

33 = 33 (holds true)

Since both equations hold true for the values of m=1 and n=5, we can conclude that the ordered pair (1, 5) is a solution to the system of equations.

To determine if the ordered pair (-2, 0) is a solution to the system of equations, we substitute the values into the equations and see if they hold true.

The length of the sides a and b are respectively 19.67 and 20.21 approximately to 2 decimal place, using the sine rule.

The sine rule is a relationship between the size of an angle in a triangle and the opposing side.

For the triangle ABC, by sine rule;

a/sinA = b/sinB = c/sinC

We first derive the angle A as follows:

75° + 35° + A = 180° {sum of interior angles of a triangle}

A = 180° - 110°

A = 70°

Thus by sine rule;

b/sin75° = 12/sin35°

b = (12× sin75°)/sin35° {cross multiplication}

b = 20.21

a/sin70° = 12/sin35°

a = (12× sin70°)/sin35° {cross multiplication}

a = 19.67

mean ± z*(standard deviation/sqrt(sample size))

Plugging in the values, we get:

95 percent confidence interval: 5.46 ± 1.96*(2.47/sqrt(100)) = 5.46 ± 0.39

99 percent confidence interval: 5.46 ± 2.58*(2.47/sqrt(100)) = 5.46 ± 0.52

(b) For the 95 percent confidence interval, the interval is 5.46 ± 0.39, which means that we can be 95 percent confident that the true mean waiting time u is between 5.07 and 5.85 minutes. Since 6 minutes falls outside this interval, we cannot be 95 percent confident that u is less than 6 minutes.

(c) For the 99 percent confidence interval, the interval is 5.46 ± 0.52, which means that we can be 99 percent confident that the true mean waiting time u is between 4.94 and 5.98 minutes. Since 6 minutes falls outside this interval, we cannot be 99 percent confident that u is less than 6 minutes.
