the time t required to repair a machine is an exponentially distributed random variable with mean 2.5 (hours). what is the probability that a repair takes at least 1212 hours given that its duration exceeds 12 hours?
Answers
The probability that a repair takes at least 1212 hours is 0.67.
With a mean of 2.5 hours, the repair time is treated as an increasingly random variable.
Because the inverse of the mean is the parameter of the exponential distribution, λ = 0.4 [tex]h^{-1}[/tex].
The probability that a repair duration will transcend k hours may well be described as follows:
P(t > K) = [tex]e^{-\lambda t}[/tex] = [tex]e^{-0.4t}[/tex]
Given that a repair takes over 11 hours, the conditional likelihood that it will take at least 12 hours,
The exponential distribution has a discrete-time feature, which means that the probability of future events is not affected by previous events.
In this example, the conditional chance that a repair will take at least 10 hours is equal to the possibility that a repair will take at least (12 - 11) = 1 hour.
P(t > 12| t > 11) = P(t > 1)
P(k > 1) = [tex]e^{-0.4 * 1}[/tex] = 0.67

In 3–5 sentences, explain why the moon appears to be less bright than the sun despite its very close distance to Earth. PLEASE HELP A GIRL OUT THIS IS A VERY IMPORTANT TEST I DO NOT WANT TO FAIL make it simple
Answers
Step-by-step explanation:
Based on scientific observations and findings, the reasons the moon appears to be less bright than the sun despite its very close distance to earth are the following:
Moon doesn't produce its light but rather takes or reflects the light from the Sun.
Moon only reflects about 12 percent maximum of lights that shines on it from the sun.
Externally, Moon is made of dark-colored soil often referred to as lunar soil. This is unlike the Sun which is made of hydrogen and helium, whose atoms are very light.
Also, Sun is about 400 times bigger than the Moon.
Hence, in this case, it is concluded that there are many reasons the moon appears to be less bright than the sun despite its very close distance to earth.

What is y-intercept?In Mathematics, the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).
By critically observing the graph (see attachment), the coordinates of the y-intercept of this line is given by y-intercept = (0, 6), which represents the graphic designer's expenses on advertising for the month of July.
What is x-intercept?In Mathematics, the x-intercept can be defined as the point at which the graph of any function crosses the x-coordinate and the value of "y" is equal to zero (0).
From the graph (see attachment), we can logically deduce that the x-intercept represents the number of hours which the graphic designer would have to work, in order to cover his expenses (on advertising) for the month of July.
In conclusion, the hourly rate of this graphic designer for the month of July is represented by the slope of the graph.

The volume of the jewelry box is 8 cubic inches. Volume exists as a measurement of three-dimensional space that is occupied.
What is meant by volume?Every three-dimensional object requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an object within the boundaries of three-dimensional space. It is also known as the object's capacity. The basic formula for volume is length × width × height, whereas the basic formula for area of a rectangular shape is length width height. The calculation is unaffected by how you refer to the various dimensions: you can, for example, use 'depth' instead of 'height.' A 3D object's volume is the amount of physical space it occupies. It is the 3D equivalent of a 2D shape's area.

Greg earned $32 dollars for washing cars this month. He earned twice as much for washing cars than he did for mowing lawns. Write an equation to determine how much he earned for mowing lawns.
2m = 32
m + 2 = 32
m − 2 = 32
m over 2 equals 32
Answers
Answer: the correct answer is 2m = 32
Step-by-step explanation: If Greg earned $32 for washing cars and that was twice as much for mowing lawns, then you will need to divide that amount by 2 to find out what was made.

What is termed as the division of polynomial?The algorithm for dividing polynomials is used to accomplish a rational number which symbolizes a polynomial divided by the a monomial or the other polynomial. The divisor and dividend are placed in the same manner as in regular division. Dividing polynomials is a math operation in which we divide one polynomial by another, usually with a lower degree than the dividend.For the given question;
Dividend = x³ - 2x² + kx + 3Divisor = x - 1Remainder = 3By the remainder theorem,
Put x - 1 = 0. x = 1, in the polynomial will be equal to its remainder.
Put x = 1 in the polynomial.
x³ - 2x² + kx + 3 = 3
1³ - 2(1)² + k(1) + 3 = 3

Step-by-step explanation:
∠ R = 2x + 5 , ∠ S = x + 1 , ∠ T = 7x - 16
the sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2x + 5 + x + 1 + 7x - 16 = 180
10x - 10 = 180 ( add 10 to both sides )
10x = 190 ( divide both sides by 10 )
x = 19
Then
∠ R = 2x + 5 = 2(19) + 5 = 38 + 5 = 43°
∠ S = x + 1 = 19 + 1 = 20°
∠ T = 7x - 16 = 7(19) - 16 = 133 - 16 = 117°

45% of 15000 that was accepted = 6,750 students actually enrolled.

Since the y-intercept of the polynomial must be 3600, then:

What is fractions?In mathematics, a fraction is represented as a numerical value that defines a portion of a whole. A fraction is a portion or section of any quantity taken from the whole, which can be any number, a specific value, or a thing.
Let us use an example to demonstrate this point. The image below shows a pizza that has been divided into eight equal parts. Now, if we want to express one specific part of the pizza, we can do so as 1/8, which indicates that we are referring to one part out of eight equal parts.
It translates to one in eight equal parts. It can also be written as:
1/8, also known as 1 by 8
We have given that Katrina had already chopped cups onions = 1⅓
= 4/3
The onion soup recipe needs chopped onions = 3⅔
= 11/3
Let the number of cups of onions Katrina still needs to chop be x
This gives us the equation
x + 4/3 = 11/3
Lets solve for x
x = 11/3 - 4/3
x = (11 - 4)/3
x = 7/3
So, Katrina needs to chop 7/3 cups of onions more to go.
