On analyzing the data given in question we get to know that the sensitivity is negative.
Our function is 40 + 24 x 2.4 /1 + 4x to the point.
For the time being, our first task is to determine the sensitivity, which is the derivative of our discovery. The quotient rule, whose derivative we shall be utilizing, says that the derivative of F org equals G f prime minus f g prime all over g squared.
The bottom function is one plus four times the top function's derivative, or 40.4 times. 40 has a derivative of zero.
When a light source is x cm away from a light probe, the light's intensity is measured as y microwatts per square cm. The outcomes are displayed as ordered pairs( x , y).
So we just need to multiply 24 x240.4.
Using the power rule, we can reduce the 0.4 point to 9.6 x to the minus 0.6.
We subtract one from the initial exponents minus the top function 40 + 24 x to the point for times the bottom function's derivative 10 So we have the derivative of four additional 40.4 by the power rule,
we bring down the 0.4 multiplied by four against 1.6 next to the minus 0.6, and we divide all of that by one plus four x to the 40.4 squared.

Is ( 2,-1) a solution? yes or no
Answer:
(-2,-7) , yes
(2,-1) , no
Step-by-step explanation:
the question says y is less than or equal to -2 . In the first order pair (-2,-7) , x= -2 & y = -7 in the number line -2 comes first than -7 it means -2 is grater than -7 so the answer is yes but in the second order pair (2,-1) the value of x is 2 and the value of y is = -1 thus -1 is grater than -2 however the question says y should be less or equal but not greater than -2 so the answer is yes for the first order pair and no for the second one

young's modulus is a quantitative measure of stiffness of an elastic material. suppose that for metal sheets of a particular type, its mean value and standard deviation are 85 gpa and 2.3 gpa, respectively. suppose the distribution is normal. (round your answers to four decimal places.)
(a) Calculate P(79 x 81) when n = 25. (b) How likely is it that the sample mean diameter exceeds 81 when n = 36? You may need to use the appropriate table in the Appendix of Tables to answer this question
(a) Probability that sample mean lies between 79 and 81 is 0.9946.
(b) It is 0.04% likely is it that the sample mean diameter exceeds 81 when n = 36.
We are given that the metal sheets of a particular type, its mean value and standard deviation are 85 GPA and 2.3 GPA, respectively.
Suppose the distribution is normal.
Let X = sample mean diameter
The z-score probability distribution for sample mean is given by;
Z = (X - μ) / (σ / √n)
where,
μ = population mean = 85 GPA
σ = standard deviation = 2.3 GPA
n = sample size = 25
(a) Probability that sample mean lies between 79 and 81 is given by
= P(79<X<81) = P(X<81) - P(X≤79)
P(X<81) = P {(X - μ) / (σ / √n) < (81 - 85) / (2.3 / √25) = P(Z < 2.78) = 0.9973
P(X<79) = P {(X - μ) / (σ / √n) < (79 - 85) / (2.3 / √25) = P(Z < 2.78) = 0.0027
The above probability is calculated by looking at the value of x = 2.78 in the z table which has an area of 0.9973.
Here, P(79 < X < 81) = 0.9973 - 0.0027 = 0.9946
(b) Probability that the sample mean diameter exceeds 81 when n = 36 is given by = P(X > 81)
P(X<81) = P {(X - μ) / (σ / √n) < (81 - 85) / (2.3 / √25) = P(Z < 3.33) = 0.0004
The above probability is calculated by looking at the value of x = 3.33 in the z table which has an area of 0.9996.
Therefore, probability that sample mean lies between 79 and 81 is 0.9946 and it is 0.04% likely is it that the sample mean diameter exceeds 81 when n = 36.

I want to know some example of a continuous function which is continuous at exactly one point. We know that f(x)=1x is continuous everywhere except at x=0. But i think this in reverse manner but i dont get any example. So please help me out!
Examples of a continuous function that is continuous at exactly one point are x=0,1,2,3,4.
In mathematics, a continuous function is one where a continuous variation of the argument results in a continuous variation of the function's value (i.e., a change without a leap). This indicates that there aren't any discontinuities or sudden changes in value. More specifically, a function is continuous if it is possible to guarantee that its value will not vary significantly even with arbitrarily tiny changes to its parameter.
We know that the modulus function,
f(x)=∣x∣ is continuous but not differentiable at x=0.
So,
f(x)=∣x∣+∣x−1∣+∣x−2∣+∣x−3∣+∣x−4∣ is continuous but not differentiable at x=0,1,2,3,4.
Hence, this is the answer.

The cross-country team had a fundraiser selling wreaths for $25 each. They made $15 for each wreath they sold. If they sold 114 wreaths, (a) how much money did they pay to make each wreath, (b) how much money did they collect, and (c) how much money did they make? If they made $180, (d) how many wreaths did they sell?
Answer:
(a) They paid $25-$15=$<<25-15=10>>10 to make each wreath.
(b) They collected $15114=$<<15114=1710>>1710.
(c) They made $1710-$10114=$<<1710-10114=180>>180.
(d) They sold $180/$15=<<180/15=12>>12 wreaths.
Step-by-step explanation:
Sure, here is a breakdown of the solution:
(a) The cross-country team paid $10 to make each wreath because they sold the wreaths for $25 and made $15 for each wreath they sold, so the cost to make each wreath was $25-$15=$10.
(b) They collected $1710 because they sold 114 wreaths and made $15 for each wreath they sold, so they collected a total of $15*114=$1710.
(c) They made $180 because they collected $1710 and it cost them $10 to make each wreath, and they sold 114 wreaths, so the total cost of making all the wreaths was $10*114=$1140. They made $180 because they collected $1710 and it cost them $1140 to make all the wreaths, so their profit was $1710-$1140=$180.
(d) They sold 12 wreaths because they made $180 and it cost them $15 to make each wreath, so they sold $180/$15=12 wreaths.

he graphed line shown below is y = negative 2 x minus 8.
On a coordinate plane, a line goes through (negative 4, 0) and (negative 2, negative 4).
Which equation, when graphed with the given equation, will form a system that has infinitely many solutions?
y = negative (2 x + 8)
y = negative 2 (x minus 8)
y = negative 2 (x minus 4)
Answer: A
Step-by-step explanation:
Our given equation is: y = -2x - 8
In order to have an equation with infinitely many solutions, it needs to be the same as the given equation.
Look at the answer choices:
A) y = -(2x + 8) = -2x - 8
This is the exact same equation, which means that any solutions for the given will also be solutions for this one. That means there will be infinitely many solutions.
B) y = -2(x - 8) = -2x + 16
We can tell this is definitely not the same as the given, so eliminate.
C) y = -2(x - 4) = -2x + 8
Again, this has a +8 instead of -8, so it's not the same and wrong.
D) y = -(-2x + 8) = 2x - 8
Here, we have positive 2 as the slope instead of -2, so it's not the same and wrong. Thus, the answer is A.

Regression analysis, regression, and immigration analyst analysis are the solutions.
What is Regression analysis?Regression analysis is a group of statistical procedures used in statistical modeling to determine the relationships between a dependent variable (often referred to as the "outcome" or "response" variable, or a "label" in machine learning jargon), and one or more independent variables (often referred to as "predictors," "covariates," "explanatory variables," or "features").
In linear regression, the most typical type of regression analysis, the line (or a more complicated linear combination) that most closely matches the data in terms of a given mathematical criterion is found.
When using the ordinary least squares method, for instance, the specific line (or hyperplane) that minimizes the sum of squared differences between the genuine data and that line is computed (or hyperplane).
This enables the researcher to estimate the for precise mathematical reasons (see linear regression).
Hence, Regression analysis, regression, and immigration analyst analysis are the solutions.

What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
From the ideal gas equation, we know that,
pressure is directly proportional to the temperature,
So,
P₁ / P₂ = T₁ / T₂
Where,
P₁ and T₁ are the initial pressure and temperature,
P₂ and T₂ are the final pressure and temperature.
Substitute the values,
P₁ / P₂ = 300 / 900
P₂ = 3P₁
