After answering the given query, we can state that the function slope changes at a rate of 3 between x=5 and x=8.
What is slope?The inclination of a line determines how sharp it is. A gradient gradient is gradient overflow is an algebraic formula for the gradient. The vertical change (run) between two spots is divided by the height change (rise) between the same two locations to determine the slope.
The equation for a straight line, written as y = mx plus b, is represented using the curve form of a formula. The slope is m, b is b, and the line's y-intercept is located at these points. (0, b). As an example, consider the y-intercept and slope of the equation y = 3x - 7. (0, 7). The y-intercept is situated where the inclination of the path is m, b is b, and (0, b).
the coordinates (5, 2) and (8, 11) to determine the function's rate of change. We'll apply the slope formula:
slope equals (y2 + y1)/. (x2 - x1)
Inserting the values:
slope = (11 - 2) / (8 - 5)
slope = 9 / 3
slope = 3
Consequently, the function changes at a rate of 3 between x=5 and x=8.

During a walk, walkers discover a car that has fallen to the bottom of a 20m high vertical cliff. It is 10m from the foot of the cliff. The police investigation reveals that the braking marks (perpendicular to the edge) start at 7.5m from the upper (horizontal) edge of the cliff and that the acceleration (braking!) was -5m/s. The chief sergeant concludes an accident. Calculate the speed of the car before the start of braking and the duration of the driver's anxiety (braking & fall).After the calculation, I got t1 from cliff = 2 sec, I got the Vf from the baking = 5m/s, I need to find V0 before baking (using this formula = d=v0t+1/2at^2),
Given, Height of the cliff = 20 m Distance of the car from the foot of the cliff = 10 m.
The time taken by the car to fall from the cliff can be found using the formula:
\(`h = (1/2) g t^2`\)
Where h is the height of the cliff, g is the acceleration due to gravity and t is the time taken by the car to fall from the cliff.
Substituting the given values,`20 = (1/2) × 9.8 × t^2`
Solving for t, `t = sqrt(20/4.9)` = 2.02 s
Let the initial velocity of the car be V0 and the time taken for the car to come to rest after applying brakes be t1.
Distance covered by the car before coming to rest can be found using the formula: `\(s = V0t1 + (1/2) (-5) t1^2\)`
Where s is the distance covered by the car before coming to rest.
Simplifying the above equation,\(`2.5 = V0 t1 - (5/2) t1^2`\)
Substituting the given values,`5 = V0 - 5 t1`
Solving the above two equations,\(`V0 = 32.5/2 t1`\)
Simplifying the above equation,`V0 = 16.25 t1`
Substituting the value o\(f t1,`V0 = 16.25 × 2` = 32.5 m/s\)
Therefore, the speed of the car before the start of braking is 32.5 m/s.

You roll a twelve-sided die (having values one through twelve on its faces). What is the probability that the value of the roll will be a composite number?
show work pls!
help pls!
Step-by-step explanation:
Probability
Probability is a measure of the likelihood that an event will happen.
When dealing with probability, the outcomes of a process are the possible results. For example, when a die is rolled, the possible outcomes are 1, 2, 3, 4, 5, and 6. In mathematical language, an event is a set of outcomes, which describe what outcomes correspond to the "event" happening. For instance, "rolling an even number" is an event that corresponds to the set of outcomes {2, 4, 6}. The probability of an event, like rolling an even number, is the number of outcomes that constitute the event divided by the total number of possible outcomes. We call the outcomes in an event its "favorable outcomes".

A mobile set after allowing a discount of 10% on its marked price, was sold at a gain of 20%,Had it been sold after allowing 20% discount,there would have been a profit Rs.350. Find the cost price and marked price of the mobile set.
Answer:
Let x be the cost price.
Let y be the marked price
Gain = 20%
Then , sale price = 120/100 * x = 1.2x
Now , sale price is after 10% discount from marked price.
Hence , marked price, y = 1.2x/90 * 100 =
y * 0.9 = x * 1.2
Now, with 20% discount, sale price = y * 80/100 = 0.8y
Now, profit = 0.8y — x
Now, 0.8y — x = 350
0.8 * x * 1.2/0.9 — x = 350
1.0667x — x = 350
Hence, x = 350/0.0667= Rs.5250
Hence marked price = (5250 + 350) * 100/80 = Rs.7000

A cube has a surface area of 600 square centimeters. What is the side length?
Answer:
10 cm
Step-by-step explanation:
The formula for finding the surface area of a cube is 6 x (side length)^2.
Since the surface area equals 600, you can divide the surface area by 6 (because a cube has 6 faces) so that becomes 100. The square root of 100 is 10, so the side length is equal 10 cm.

a data analyst wants to find out how much the predicted outcome and the actual outcome of their data model differ. what function can they use to quickly measure this?
Analyst can measure this through cor()function
What is Function?
Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
Concept:
The R language's cor() function is used to calculate the correlation coefficient between two vectors.
Finding the correlation between the two equities is one method of capturing this type of interaction. Using a value between -1 and 1, correlation is a measure of association between two items, in this case, stock prices. A perfect correlation of 1 indicates a positive correlation, a perfect correlation of -1 indicates a negative correlation, and a perfect correlation of 0 indicates independent stock movement. Understanding how to compute correlation in R is helpful because it is a common metric in finance.
When given a matrix, the cor() function creates a correlation matrix or determines the correlation between two vectors.

How do you fill a table with a function?
The proper method of filling a table with a function has been explained below.
Tables are helpful when we have to plot a function or we have to interpolate a function using given data points. A table usually consists of 2 or more 2 variables whose values are arranged either in a row or in a column. For filling a table with the help of a function, firstly we have to define the values of independent variables which we will input into the function to get the dependent variable's values.
When we get the value of independent data we will be inputting one of one those values in the function we will get the values of the function at the given point and hence the function will be filled by the output values.

(a) The area to the left of Z = -1.11 is (Round to four decimal places as needed.) (b) The area to the left of Z=-0.51 is (Round to four decimal places as needed.) (c) The area to the left of Z= -0.35 is (Round to four decimal places as needed.) (d) The area to the left of Z = -0.03 is (Round to four decimal places as needed.)
(a) The area to the left of Z = -1.11 is 0.1331.
(b) The area to the left of Z = -0.51 is 0.3050.
(c) The area to the left of Z = -0.35 is 0.3632.
(d) The area to the left of Z = -0.03 is 0.4918.
To find the area under the standard normal curve to the left of each given Z-score, you can use a standard normal (Z) table or a calculator with a built-in normal distribution function. Here are the steps:
1. Locate the Z-score in the standard normal table or enter it into your calculator's normal distribution function.
2. Find the corresponding probability, which represents the area to the left of that Z-score.
Using these steps, you can find the area to the left of each Z-score:
(a) Z = -1.11:
The area to the left of Z = -1.11 is 0.1335 (rounded to four decimal places).
(b) Z = -0.51:
The area to the left of Z = -0.51 is 0.3050 (rounded to four decimal places).
(c) Z = -0.35:
The area to the left of Z = -0.35 is 0.3632 (rounded to four decimal places).
(d) Z = -0.03:
The area to the left of Z = -0.03 is 0.4901 (rounded to four decimal places).
Therefore, the area under the standard normal curve to the left of any Z-value represents the proportion or percentage of the total area under the curve that is less than that Z-value. It can also be interpreted as the probability of obtaining a standard normal random variable less than that Z-value.
