The probability that a rental car delivered to the firm will need a tune-up is 0.03% or 0.000306 and the probability that it came from agency 2 is 39.15% or 0.3915.

(a) Let P(A1), P(A2), and P(A3) be the probabilities that a rental car comes from agency 1, agency 2, and agency 3, respectively, and let P(T) be the probability that a rental car needs a tune-up. Then, using the law of total probability, we have:

P(T) = P(T|A1)P(A1) + P(T|A2)P(A2) + P(T|A3)P(A3)

P(T) = 0.05(0.0036) + 0.02(0.0006) + 0.02(0.0058)

P(T) = 0.00018 + 0.000012 + 0.000116

P(T) = 0.000306

Therefore, the probability that a rental car delivered to the firm will need a tune-up is 0.03% (or 0.000306 as a decimal).

(b) Using Bayes' theorem, we can calculate the conditional probability that a rental car came from agency 2 given that it needs a tune-up:

P(A2|T) = P(T|A2)P(A2) / P(T)

P(A2|T) = 0.02(0.0006) / 0.000306

P(A2|T) = 0.3915

Therefore, if a rental car delivered to the firm needs a tune-up, the probability that it came from agency 2 is 39.15% (or 0.3915 as a decimal).

Answer:

Step-by-step explanation:

To find the bearing of the bushwalker's finishing position from his starting point, we can use trigonometry and the concept of bearings.

First, we can draw a diagram to visualize the bushwalker's journey:

        (9 km south)

              |

              |

 (Starting point)

        O-----|-------------------> (14 km east)

              |

              |

     (Finishing point)

Next, we can use the tangent function to find the angle between the bushwalker's starting point and finishing point:

tan θ = opposite / adjacent

In this case, the opposite side is 14 km (the distance traveled east), and the adjacent side is 9 km (the distance traveled south):

tan θ = 14 / 9

We can use a calculator or reference table to find that the angle θ is approximately 56.31 degrees.

However, this is not the bearing we are looking for. In the context of bearings, the bearing of a point is the angle measured clockwise from north to the line connecting the starting point and the point in question.

To find the bearing of the bushwalker's finishing point, we need to adjust the angle θ to take into account the fact that bearings are measured from north.

First, we can find the direction of the line connecting the starting point and finishing point. This line travels 14 km east and 9 km south, so it has a slope of -9/14. We can find the angle this line makes with the horizontal axis by taking the arctangent of the slope:

tan α = -9/14

α = -30.96 degrees

Note that we use a negative sign because the line slopes downwards (southward) from left to right.

Finally, we can add this angle to the angle θ we found earlier:

Bearing = 360 - (θ + 90 + α)

       = 360 - (56.31 + 90 + (-30.96))

       = 287.7 degrees

Therefore, the bushwalker's finishing position has a bearing of approximately 287.7 degrees from his starting point.

[tex] \bf{Answer }[/tex]

We can use trigonometry to find the bearing of the finishing position from the starting point.

Using the Pythagorean theorem, we can find the length of the hypotenuse:

c² = a² + b²

where c is the length of the hypotenuse, a is the distance traveled east (14 km), and b is the distance traveled south (9 km).

Substituting the given values, we get:

c² = (14 km)² + (9 km)²

c² = 196 km² + 81 km²

c² = 277 km²

c ≈ 16.67 km (rounded to two decimal places)

Now, we can use trigonometry to find the angle between the hypotenuse and the east direction.

tan(θ) = opposite/adjacent

where θ is the angle between the hypotenuse and the east direction, opposite is the distance traveled south (9 km), and adjacent is the distance traveled east (14 km).

Substituting the given values, we get:

tan(θ) = 9 km / 14 km

θ ≈ 32.47° (rounded to two decimal places)

Therefore, the bearing of the finishing position from the starting point is approximately 32.47° south of east. Alternatively, we can describe the bearing as 157.53° east of south (180° - 32.47°), or simply as southeast.

The minimum value of multiplication of AxB is 245,376.72, which is obtained when A = 450 (rounded down from 495) and B = 545 (rounded up from 537.03).

Calculating the sum of two or more numbers is the procedure of multiplication. It is expressed as "a multiplied by b" when two numbers, let's say "a" and "b," are multiplied. Multiplication in mathematics is essentially just adding a number continuously in relation to another number.

The given values are:

A = 900 rounded to the nearest 10 = 900

B = 90.7 rounded to 1 decimal place = 90.7

We need to find the minimum value of AxB.

Multiplying A and B directly, we get:

AxB = 900 x 90.7 = 81,630

To find the minimum value of AxB, we can use the concept of AM-GM inequality which states that for two positive real numbers a and b, their arithmetic mean (AM) is greater than or equal to their geometric mean (GM):

AM ≥ GM

or

(a+b)/2 ≥ √(ab)

Applying this to our values of A and B, we get:

(A+B)/2 ≥ √(AxB)

Substituting the given values of A and B, we get:

(900 + 90.7)/2 ≥ √(AxB)

Simplifying this, we get:

495.35 ≥ √(AxB)

Squaring both sides, we get:

245,376.72 ≥ AxB

Therefore, the minimum value of multiplication of AxB is 245,376.72, which is obtained when A = 450 (rounded down from 495) and B = 545 (rounded up from 537.03).

The correct interpretation of an odds ratio of 0.75 would be (a) If not exposed the outcome is less likely since the odds ratio is less than 1.

An odds ratio of less than 1 indicates a decreased odds of the outcome in the exposed group compared to the unexposed group. Specifically, an odds ratio of 0.75 suggests that the odds of the outcome occurring in the exposed group is 25% lower than the odds of the outcome occurring in the unexposed group.

Option b is incorrect as an odds ratio of 0.75 is not necessarily close to 0, and option c is incorrect because an odds ratio of 0.75 means that the odds of the outcome in the exposed group is lower than the unexposed group, not 75 times greater. Option d is also incorrect as a protective effect would be observed if the odds ratio were less than 1.

If a point's preimage is P(x, y), then its image after a dilation with a scale factor of k and centered at the origin (0, 0) is P'(kx, ky).

The set of all points in a function's domain that correspond to a given point in the range is known as the preimage of a point in mathematics.

Formally, let f be a function that goes from a set A to a set B, and let y be a point in B. The preimage of y is the set of all points x in A where f(x) = y, or the set of all points in the domain that the function maps to the given point in the range.

If the preimage of the point P has facilitates (x, y), and the expansion focused at the beginning with a scale component of k is applied, then the directions of the picture point P' can be tracked down utilizing the accompanying recipe:

The x- and y-coordinates of P' are determined by multiplying the corresponding coordinates of the preimage point P by the scale factor k; consequently, the coordinates of the image point P' following the dilation with the origin centered on k would be (kx, ky).

The probability that the other child is a daughter is 1/2 or 50%.

The gender of each child is independent, and there are two equally likely outcomes for each child (male or female). Therefore, the probability of having a son is 1/2 and the probability of having a daughter is also 1/2. Since one child is already known to be a son, that does not affect the probability of the other child being a daughter. Thus, the probability of having a daughter as the other child is also 1/2 or 50%.

The total surface area of the triangular prism is 200 square inches.

A triangular prism is a three-dimensional geometric shape that consists of two parallel triangular bases connected by three rectangular faces.

To find the surface area of the triangular prism using the net provided, we need to find the area of each face and then add them together.

Using formulas,

Area of rectangle= [tex]length\times width[/tex] square unit.

Area of triangle = [tex]\frac{1}{2}\times Base \times Height[/tex] square unit.

The blue rectangle has a length of 5 inches and a width of 4 inches, so its area is

=> 5 x 4 = 20 square inches.

The orange rectangle has a length of 12 inches and a width of 4 inches, so its area is

=> 12 x 4 = 48 square inches.

The red rectangle has a length of 13 inches and a width of 4 inches, so its area is

=> 13 x 4 = 52 square inches.

The green triangles have a base of 12 inches and a height of 5 inches, so each triangle's area is

=> [tex]\frac{1}{2}\times12\times5[/tex]=  30 square inches.

To find the total surface area, we add the area of each face:

=> 20 + 20 + 48 + 52 + 30 + 30 = 200 square inches.

Answer:

the area of the trapezoid is (3/2)x^2 + 2x square units.

Step-by-step explanation:

Let's use "x" to represent the height of the trapezoid. According to the problem, one base measures 5 feet more than the height, so we can use "x + 5" to represent the length of that base. The other base is one foot less than twice the height, so we can use "2x - 1" to represent the length of that base.

The area of a trapezoid is given by the formula:

Area = (1/2)(sum of the bases)(height)

Substituting the expressions for the bases and the height, we get:

Area = (1/2)(x + 5 + 2x - 1)(x)

Simplifying the expression inside the parentheses, we get:

Area = (1/2)(3x + 4)(x)

Expanding the expression, we get:

Area = (3/2)x^2 + 2x

the area of the trapezoid is (3/2)x^2 + 2x square units.
