The lifetime of a particular type of car tire is normally distributed. The mean lifetime is 50,000 miles, with a standard deviation of 5,000 miles. Of a random sample of 15,000 tires, how many of the tires are expected to last for between 45,000 and 55,000 miles?
Answer:
10,240 tires
Explanation:
To calculate the percentage of tires that are expected to last for between 45,000 and 55,000 miles, we need to find P(45000 < X < 55000).
Calculator input for "normal cumulative distribution function (cdf)":
Lower bound: x = 45000Upper bound: x = 55000Mean, μ = 50000Standard deviation, σ = 5000⇒ P = 0.682689492...
⇒ P = 68.27%
Therefore, approximately 68.27% (2 d.p.) of tires are expected to last for between 45,000 and 55,000 miles.
To find the number of tires that are expected to last between 45,000 and 55,000 miles from a random sample of 15,000, multiply the found percentage by the number in the sample:
⇒ 0.682689492... × 15000 = 10240.3428...
Therefore, of a random sample of 15,000 tires, 10,240 tires are expected to last for between 45,000 and 55,000 miles.

Given that f:x=2x²+8x-10 for the domain x>/=k; find the least value of k for which f is one-one
The least value of k in which the function f is one to one is k = -∞
What is the least value of k which f is one to oneA function f is considered to be one-to-one if for every unique output y, there is only one unique input x that maps to y. In other words, it means that no two inputs map to the same output.
For the given function f:x=2x²+8x-10, we need to find the value of k for which f is one-to-one for x >= k.
To determine whether the function is one-to-one, we need to check if it passes the horizontal line test. A function is one-to-one if and only if no horizontal line intersects the graph of the function at more than one point.
Since the function is a parabola, its graph opens upwards and therefore it passes the horizontal line test. This means that the function is one-to-one for all values of x, so k can be any real number including negative values.
Hence, the least value of k for which f is one-to-one is k = -∞.

Enter line segment, point, or ray in the answer box to complete the statement. Sydney described a ruler as a length of plastic that starts at 0 and continues on to 12 inches. The geometric term that best describes Sydney's description is a .
Answer:
Segment
Explanation:
Literally, segment refer to any distance between two points.
Let's assume the length of the ruler is 20inch, this means that the distance 0 inch to 12 inch is a segment of the full length of the ruler.
Another angle to look at the segment is the length of a segment can be measured because it has two end points; the end points are the point where the segment starts and the point where it ends.
So, in the question above, the end points of the segment are 0 inch and 12 inch while the length of the segment is 12inch.
This is calculated by 12 inch - 0 inch = 12 inch.
The above description can't be said of point and rays. Point is any unit position on a line while ray is a distance that starts from a point but do not have any endpoint.

How was Malcolm X's approach to gaining civil rights different from Dr. King's? Why do you think he resisted King's approach?
Answer:
Near the end of his life, Malcolm X publicly recognized that "Dr. King wants the same thing I want — freedom!" But for most of his ministry he did not identify with King and the civil rights movement. Although both Black Muslims and King's Southern Christian Leadership Conference had the same general goals of defeating white racism and empowering African Americans, Malcolm and King had different tended to speak at different venues (street corners vs. churches) and had different aims. Malcolm, who would publicly deny that he was even an American, worked for a Nation of Islam that sought to create a separate society for its members. Malcolm rejected integration with white America as a worthwhile aim (deriding it as "coffee with a cracker") and particularly opposed non-violence as a means of attaining it. "That's what you mean by non-violent," he said, "be defenseless." In Malcolm's mind, the African American could never surrender his right of self-defense against white violence.
Explanation:
I think that because Malcolm X had a different opinion thank King's approach on the civil rights movement he wanted to stick to it.

According to Newton's 3rd Law of Motion, when you walk on the sidewalk, the push of your shoe on the ground is _______ the push of the ground on your shoe. *
Answer:
opposite
Explanation:
Newton's 3rd law of motion: If object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
so it should be opposite because the ground/floor pushes the shoe up and forward, the shoe pushes down and back.

d&t / material used for marking out plastic and it's drawing form 1
In Design and Technology (D&T), when marking out plastic materials, various tools and techniques can be employed depending on the specific requirements and characteristics of the material. The choice of marking tools largely depends on the type of plastic and the desired outcome. Additionally, the drawing form used for marking out plastic typically involves the use of technical drawings or templates to ensure accurate and precise measurements.
Marking Tools:
1. Permanent Marker: A permanent marker with a fine tip is often used to make visible and long-lasting marks on plastic materials. It allows for clear lines and can be easily applied on smooth surfaces.
2. Scriber: A scriber, which is a sharp-pointed tool, can be used to scratch or score lines onto the plastic surface. This method is particularly useful for creating precise guidelines or marking out intricate shapes.
3. Masking Tape: Masking tape can be used to create temporary markings on plastic surfaces. It provides a clear boundary for cutting or shaping operations and can be easily removed without leaving residue.
4. Stencil: Stencils are pre-designed templates with cut-out shapes or patterns. They can be used to transfer specific designs or markings onto the plastic surface accurately.
Drawing Form:
1. Technical Drawings: Technical drawings, such as orthographic projections or isometric views, are commonly used in D&T to represent the shape, dimensions, and features of a plastic component. These drawings provide precise measurements, angles, and details necessary for accurate marking out.
2. Templates: Templates are pre-made patterns or outlines that are used as guides for marking out specific shapes or profiles onto the plastic material. Templates ensure consistency and accuracy in replicating complex shapes or designs.

How are camarasaurus and diplodocus similar
Answer:
Camarasaurus and Diplodocus are similar in that they were both large-sized, herbivorous dinosaurs that lived during the Late Jurassic period. They were both members of the family Diplodocidae, and had long necks and tails, as well as relatively small heads compared to their body size. In addition, both Camarasaurus and Diplodocus were quadrupedal, meaning they walked on four legs.
Geologic Processes CFA 11 of 1411 of 14 Items Question S Use the two data tables above to answer the following questions: Predict elevation in 8 milliion years. Present Day= 2037 m 1 mya= __?__, 2 mya= __?__ 3 mya= 1947 m 4 mya=__?__ 5 mya= __?__ 6 mya= 1857 m 7 mya= __?__ 8 mya= __?__ Describe which geologic processes that caused this change in elevation
Answer:
Explanation:
Based on the data in the tables, we can predict that the elevation in 8 million years will be approximately 1857 m. This prediction is based on the trend in the data, which shows that the elevation decreases by approximately 90 m every million years. Since the elevation at 3 million years ago was 1947 m, and the elevation decreases by 90 m every million years, we can predict that the elevation in 8 million years will be 1947 m - (90 m * 5 million years) = 1857 m.
The geologic processes that caused this change in elevation are likely to be a combination of erosion and tectonic activity. Erosion is the process by which rocks and sediments are worn away by wind, water, and other natural forces, which can cause the elevation of an area to decrease over time. Tectonic activity, on the other hand, refers to the movement of the Earth's crust, which can cause the elevation of an area to change as a result of uplift or subsidence. Together, these processes can cause the elevation of an area to change over millions of years.
