What are Sets and Subsets?

A set is a mathematical representation of a group of diverse items. A set has elements or members, which can be any type of mathematical object, including numbers, symbols, lines, points in space, other geometric structures, variables, or even other sets.

When all the components of Set A are also present in Set B, Set A is said to be a subset of Set B. Alternatively said, Set B contains Set A.

Here, (3,4,5} has open ended bracket on 3 which implies it does not contain 3 .

Similarly, (3,4,5} has closed bracket on 5 which implies it contains 5.

Since, we have to check whether 4 belongs to the set or not,

4 belongs to the given set because it is a part of given set which is in the mid hence, we don't need to check bracket here.

Hence, 4 € (3,4,5} and the given statement is true.

If David uses 4 GB over the limit, then he has used a total of 6 + 4 = 10 GB of data in that month. Since his plan includes 6 GB of data, he has exceeded the limit by 4 GB.

For the extra 4 GB of data, he will be charged an additional $10 per GB, so his total extra charge will be $10 x 4 = $40.

Therefore, in a month where David used 4 GB over the limit, he would have to pay $30 (the base cost of the plan) plus $40 (the extra charge for the additional data), for a total of $70.

If David went over the limit by x GB, then his total data usage for the month would be 6 + x GB. He would then be charged $10 for each GB over the limit, so his extra charge would be $10 x x.

Therefore, in a month where David went over the limit by x GB, he would have to pay $30 (the base cost of the plan) plus $10x (the extra charge for the additional data), for a total of $30 + $10x.

The domains of the composite function (f/g)(4) and (f + g)(4) for f(x) = x² + 2x - 3 and g(x) = x² - 9 are equal to 3 and 28 respectively.

A function is composite when the co- domain of the first mapping is the domain of the second mapping

We shall evaluate the domains of the function (f/g)(4) and (f + g)(4) as follows:

(f/g) = (x² + 2x - 3)/(x² - 9)

by factorization of the right hand side;

(f/g) = (x - 1)(x + 3)/(x - 3)(x + 3)

(f/g) = (x - 1)/(x - 3)

(f/g)(4) = (4 - 1)/(4 - 3)

(f/g)(4) = 3

(f + g) = x² + 2x - 3 + x² - 9

(f + g) = 2x² + 2x - 12 {simplify like terms}

(f + g)(4) = 2(4)² + 2(4) - 12

(f + g)(4) = 28

Therefore, the domains of the composite function (f/g)(4) and (f + g)(4) for f(x) = x² + 2x - 3 and g(x) = x² - 9 are equal to 3 and 28 respectively.

So the correct answer is $6,645, or option D. If just a portion of that sum was spent on print advertising.

Multiplication is the inverse of division. If 3 groups of 4 add up to 12, 12 split into 3 equal groups adds up to 4 in each group in division. The basic purpose of splitting is to determine how many equal groups develop or how many people are in each group when distributing equally. A division in mathematics is the process of dividing a specified amount into equal pieces. For example, we can split a group of 20 people into four groups of five people each, or five groups of four people each, and so on.

Here,

If half of the $13,290 was spent on print advertising, then $13,290 / 2 = $6,645 was spent on print advertising.

Therefore, $13,290 - $6,645 = $6,645 was spent on TV advertising.

Therefore , the solution of the given problem of equation comes out to be Matias operated with the number 760.

A straightforward regression graph is created using the equation y=mx+b. B is the slope, and m is the y-intercept. Even though the portion before it consists of separate sections, it is frequently described as just a "simple algorithm combining many variables". Two factors make up bivariate linear equations. There are no solutions known for application issues involving linear equations.

Here,

When Matias moved the decimal point in 7.6 two places to the left, he essentially divided 7.6 by 100, which is equivalent to dividing by 10 raised to the power of 2.

So, if we let x be the number Matias operated with, we can set up the equation:

x ÷ 10² = 7.6

Simplifying:

x ÷ 100 = 7.6

Multiplying both sides by 100:

x = 760

Therefore, Matias operated with the number 760.

The method of transformation is used to find the density functions of U1, U2 and U3 when given the probability density function of a random variable Y. The equation for the transformation of a random variable Y to U is U = g(Y), where g is a function of Y. To find the density functions of U1, U2 and U3, we need to first calculate the derivatives of U1, U2 and U3 with respect to Y, which are given by dU1/dY = 2, dU2/dY = -1/2 and dU3/dY = 2Y. Then, the density functions of U1, U2 and U3 can be calculated using the formula fU(u) = fY(g-1(u)) * |dg-1/du|, where fU(u) and fY(y) denote the density functions of U and Y, respectively, and g-1 is the inverse of g. For U1, U2 and U3, g-1(u) is y = (u+1)/2, y = 2/u and y = √u, respectively. Therefore, the density functions of U1, U2 and U3 can be calculated as fU1(u) = 2(2 - (u+1)), 0 < u < 1, 0, elsewhere; fU2(u) = 4/u2, 0 < u < 1, 0, elsewhere; and fU3(u) = 2/√u, 0 < u < 1, 0, elsewhere.

A central angle in a circle measures 52 degrees. 13° is the measure of an inscribed angle that intercepts the same arc.

An arc's inscribed angle is the angle that it occupies at any given point on the circle. The angle created when two chords cross on a circle's interior is known as a "inscribed angle" in geometry. The angle formed at a specific location on the circle by two specified points on the circle can also be used to define it. Two chords of the circle that share an endpoint define an inscribed angle in the same way.

Half of the size of the central angle that corresponds with the intercepted arc makes up the size of an inscribed angle. An inscribed angle's measurement is equal to half of its intercepted arc's measurement.

Thus, central angle = 52°

so, intercepted arc = 26°

We have shown that for any eigenvalue λ of A, 1-λ is an eigenvalue of -A. So, the eigenvalues of -A are 1-λ1, 1-λ2, ..., 1-λn, where λ1, λ2, ..., λn are the eigenvalues of A.

Eigenvalues are scalar values that are associated with a linear transformation of a matrix and are used to represent the behavior of a linear system. They represent the factor by which a linear transformation scales the direction of a vector. Eigenvalues play an important role in many areas of mathematics, including linear algebra, physics, engineering, and statistics. If a matrix A has an eigenvector x and an eigenvalue λ, then A can be represented as a scalar multiplication of x by λ: A x = λ x. The eigenvalues of a matrix can be used to determine its stability, to find the diagonalization of the matrix, and to determine the eigenvectors that represent the most important directions of a linear transformation.

The eigenvalues of a matrix A are scalars that satisfy the equation Av = λv, where v is a non-zero eigenvector and λ is the corresponding eigenvalue. If λ is an eigenvalue of A, then 1-λ is an eigenvalue of -A.

To see why this is true, let's consider an eigenvector v of A with eigenvalue λ. Then, Av = λv. We can multiply both sides of this equation by -1 to obtain:

-Av = -λv

Now, we can substitute -A for A and 1-λ for λ:

(-A)v = (1-λ)v

Thus, we have shown that for any eigenvalue λ of A, 1-λ is an eigenvalue of -A. So, the eigenvalues of -A are 1-λ1, 1-λ2, ..., 1-λn, where λ1, λ2, ..., λn are the eigenvalues of A.

distinct ways !

STATICS and STATICS are 2 different ways to arrange them. have you noticed the difference ?

no, of course not. I only exchanged the 2 S. the same problem with the 2 T.

while they are different permutations, their arrangements are not distinctly different. to us observers they look the same.

so, for the 7 letters, 7! is not the full answer.

these 7! permutations include all the ones, where we only change the S and the T with each other.

we need to eliminate those. we do this by dividing by the S permutations (2! = 2) and the T permutations (again, 2! = 2).

so, the answer is

7! / (2×2) = 5040 / 4 = 1260

the 7 letters can be arranged in 1260 distinctly different ways.

The null hypothesis is that the percentage of Americans who start the day with cereal for breakfast is 80%. The alternative hypothesis is that the percentage is less than 80%.

Let p be the true proportion of Americans who start the day with cereal. The sample proportion is 70/100 = 0.7. The standard error is √(p(1-p)/n) = √(0.8(0.2)/100) = 0.04.

The test statistic is (0.7 - 0.8) / 0.04 = -2.5. From the standard normal distribution table, the p-value for a one-tailed test with a test statistic of -2.5 is 0.0062.

Since the p-value (0.0062) is less than the significance level (0.05), we reject the null hypothesis. There is evidence to support the claim that the percentage of Americans who start the day with cereal for breakfast is less than 80%.

y' = (y-3)(y+3)exp(y)

This differential equation has equilibrium solutions at y=0 and y=3, and y' is positive for -inf < y < 0 and 3 < y < inf and negative for 0 < y < 3.

1. Set y′ = 0 to get the equilibrium solutions

y′ = 0 → y = 0 and y = 3

2. Find the sign of y′

y′ = (y-3)(y+3)exp(y)

For y < 0, y′ is positive

For 0 < y < 3, y′ is negative

For y > 3, y′ is positive

This differential equation has two equilibrium solutions at y=0 and y=3, meaning the value of y does not change when the equation is applied.

To determine the sign of the equation, we can look at the equation y′ = (y-3)(y+3)exp(y). For y < 0, y′ is positive. This means that when y is less than 0, the equation increases in value. For 0 < y < 3, y′ is negative. This means that when y is in between 0 and 3, the equation decreases in value. And for y > 3, y′ is positive. This means that when y is more than 3, the equation increases in value.

Overall, the equation behaves as expected: it increases when y is less than 0 and more than 3, and decreases when y is between 0 and 3. This is what we would expect in order for the equation to have the equilibrium solutions at y=0 and y=3.
