what is function ?The subject of mathematics includes quantities and their variations, equations and related structures, forms and their locations, and places where they can be found. The term "function" refers to the relationship between a set of inputs, each of which has an associated output. A relationship between inputs and outputs in which each input leads to a single, distinct result is known as a function. Each function is given a domain and a codomain, or scope. Usually, f is used to denote functions (x). input is an x. There are four main types of functions accessible. based on the following factors: on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

A set of 4 consecutive even integers sums to -252. What is the value of the greatest integer?
Let us assume that the first even number is x
Then the first consecutive even is x + 2
The second consecutive even is x + 4
The third consecutive even is x + 6
The four consecutive even numbers are
x, x + 2, x + 4, x + 6
Their sum is -252, then
Add them and equate the sum by -252
\(x+x+2+x+4+x+6=-252\)Add the like terms on the left side
\(\begin{gathered} (x+x+x+x)+(2+4+6)=-252 \\ 4x+12=-252 \end{gathered}\)Now let us solve the equation
Subtract 12 from both sides
\(\begin{gathered} 4x+12-12=-252-12 \\ 4x=-264 \end{gathered}\)Divide both sides by 4 to find x
\(\begin{gathered} \frac{4x}{4}=\frac{-264}{4} \\ x=-66 \end{gathered}\)That means, the first even number is -66
-66 + 2 = -64
-66 + 4 = -62
-66 + 6 = -60
The four consecutive even numbers are
-66, -64, -62, -60
Let us find their sum to check the answer
-66 + -64 + -62 + -60 = -252
Then the answer is right

How can u find a geometry-big circle mAB=56 mBC=59 mCD=63 mDE=63 mEF= 31
To find the measure of the geometry-big circle, we need to sum up the measures of all the arcs around the circle.
We are given the following measures:
\(\sf\:m\angle AB = 56 \\\)
\(\sf\:m\angle BC = 59 \\\)
\(\sf\:m\angle CD = 63 \\\)
\(\sf\:m\angle DE = 63 \\\)
\(\sf\:m\angle EF = 31 \\\)
To find the measure of the geometry-big circle, we add up these measures:
\(\sf\:m\angle AB + m\angle BC + m\angle CD + m\angle DE + m\angle EF \\\)
Substituting the given values:
\(\sf\:56 + 59 + 63 + 63 + 31 \\\)
Simplifying the expression:
\(\sf\:272 \\\)
Therefore, the measure of the geometry-big circle is 272.

In a history class, 30 students were asked about other courses that they were enrolled in: 20 said they were taking math, 22 were taking English and 26 students were in either math or English. a) How many students are taking both math and English b) How many are in neither c) What percent of the students are taking math but not English
16 students take both maths and english, 4 students took neither and 15.38% of the students are taking math but not English
What is probability?Probability is the likelihood of occurrence of an event. It is given by:
Probability = number of occurrence / total possible outcomes.
Let x represent the number of students that took both maths and english, hence:
Number of students taking only maths = 20 - x
Number of students taking only english = 22 - x
26 = 20 - x + (22 - x) + x
42 - x = 26
x = 16
b) Those who took neither = 30 - 26 = 4
c) those taking only math = 20 - 16 = 4.
Percentage = (4/26) * 100 = 15.38%

Answer:
i got 6 sorry if wrong
Step-by-step explanation:
Suppose X,Y and Z are three different random variables. Let X obey a Bernoulli Distribution. The probability distribution function is. c is a constant here.
Let Y obey the Standard Normal (Gaussian) Distribution, which can be written as Y N(0,1). X and Y are independent. Meanwhile, let Z = XY.
Calculate the covariance of Y and Z (Cov(Y, Z)) and determine whether values of c would affect the correlation.
The value of c does not affect the covariance of Y and Z.
How did we arrive at this assertion?The covariance of Y and Z can be calculated as Cov(Y, Z) = E[YZ] - E[Y]E[Z]. Since X is Bernoulli with parameter p and E[X] = p, we have E[Z] = pE[Y]. Hence,
Cov(Y, Z) = E[YZ] - E[Y]E[Z]
= E[YXY] - pE[Y]^2
= pE[Y^2 X] - pE[Y]^2
= p(E[Y^2]E[X] + Var[Y]p) - pE[Y]^2
= p(1 * p + 1 * p^2) - p^2
= p - p^2
It can be seen that the value of c does not affect the covariance of Y and Z.

Answer:
x = 15 , y = 21
Step-by-step explanation:
using Pythagoras' identity

x² + 8² = 17²
x² + 64 = 289 ( subtract 64 from both sides )
x² = 225 ( take square root of both sides )
x = \(\sqrt{226}\) = 15
in Δ ADC
8² + DC² = 10²
64 + DC² = 100 ( subtract 64 from both sides )
DC² = 36 ( take square root of both sides )
DC = \(\sqrt{36}\) = 6
