Step-by-step explanation:

In parallelogram STVU,

\( m\angle TVU + 60\degree = 180\degree\) (linear pair angles)

\( m\angle TVU = 180\degree - 60\degree \)

\( m\angle TVU = 120\degree \)

\( m\angle UST= m\angle TVU =120\degree \)(Opposite angles of a parallelogram)

\( m\angle USR= 120\degree(\because S-R-T) \)

\( 108\degree + m\angle USR+m\angle PSR= 360\degree\)

\( 108\degree + 120\degree+m\angle PSR= 360\degree\)

\( 228\degree + m\angle PSR= 360\degree\)

\( m\angle PSR= 360\degree - 228\degree \)

\( m\angle PSR= 132\degree \)

\( y+m\angle PSR= 180\degree \)

(Adjacent angles of a parallelogram)

\( y+ 132\degree= 180\degree \)

\( y= 180\degree-132\degree\)

\( y= 48\degree\)

The linear system of equation y = -12x and 4x+2y= -8 has only one solution at 0.4,-4.8) .

The linear equation is  y = -12x and 4x+2y = -8

Now we solve the equations by substitution:

Using the value of y from the first equation and substituting in the second equation we get:

4x+2y = -8

or, 4x + 2(-12x)= -8

or, 4x -24x = -8

or, -20 x = -8

or, x = 0.4

At x=0.4 , y = -4.8

Hence solution is (0.4,-4.8) which represents the point of intersection of the two lines.

The collection of variable values in a linear equation that yields every feasible solution is referred to as the "solution of a linear equation." Unknown variables are used as one or more variables in linear equations to model real-world issues.

The solutions are the points at which the lines or planes used to describe the linear equations intersect or meet. The set of values for each variable in a system of linear equations is known as the solution set.

Answer: Please see answer in explanation column

Step-by-step explanation:

Place value tells us how much value or the worth of a number. In a decimal number as such below, The numbers before the decimal point are whole numbers, while after the decimal number are regarded as fractions .

In the number 7.759,

The place value of One of the 7 represents 7 unit  = 7.0

and the other 7 represents 7 tenths = 7/ 10  of unit= 0.7

We can see from above the the 7 unit, a whole number  is greater than 7 tenths which is a fraction.

Euler's formula can be used to derive the trigonometric identities.

Euler's formula states that for any real number x, the complex exponential function can be represented as follows:

\(\[e^{ix} = \cos(x) + i\sin(x)\]\)

where \(e\) is the base of the natural logarithm, \(i\) is the imaginary unit, \(\cos(x)\) represents the cosine function, and \(\sin(x)\) represents the sine function. This formula provides a powerful connection between exponential functions and trigonometric functions.

To derive trigonometric identities using Euler's formula, we can start with the exponential form of Euler's formula and manipulate it algebraically. Let's consider the complex exponential function for two angles, \(x\) and \(y\):

\(\[e^{ix} \cdot e^{iy}\]\)

Using the properties of exponents, we can simplify this expression:

\(\[e^{ix} \cdot e^{iy} = e^{i(x + y)}\]\)

Now, applying Euler's formula to both sides, we get:

\(\[\cos(x) + i\sin(x) \cdot \cos(y) + i\sin(y) = \cos(x + y) + i\sin(x + y)\]\)

By comparing the real and imaginary parts of this equation, we obtain the sum and product formulas for cosine and sine:

\(\[\cos(x) \cdot \cos(y) - \sin(x) \cdot \sin(y) = \cos(x + y)\]\[\sin(x) \cdot \cos(y) + \cos(x) \cdot \sin(y) = \sin(x + y)\]\)

These are known as the angle addition formulas, and they form the basis for deriving other trigonometric identities. By manipulating and applying these formulas, we can establish relationships such as double-angle formulas, half-angle formulas, and more.

Answer:

23/30

Step-by-step explanation:

In estimating a population mean, an interval estimate is more likely to be correct than a point estimate. An interval estimate provides a range of values within which the true population mean is likely to fall, while a point estimate provides only a single value.

When estimating a population mean, using an interval estimate is more likely to be correct because it accounts for the uncertainty associated with the estimate. A point estimate, on the other hand, provides a single value that is assumed to represent the true population mean. However, due to sampling variability and potential errors in measurement, a point estimate is prone to error and may not accurately reflect the true population mean.

By using an interval estimate, which includes a range of values, we have a measure of uncertainty. The range is typically constructed based on a certain level of confidence, such as a 95% confidence interval. This means that if we were to repeat the sampling and estimation process many times, the true population mean would be expected to fall within the estimated interval in 95% of those repetitions.

The interval estimate takes into account the variability in the data and provides a more realistic representation of the true population mean. It provides a margin of error and acknowledges that the point estimate is just one possible value among many that could have been obtained through sampling.

Therefore, when estimating a population mean, an interval estimate is preferred because it not only provides a point estimate but also quantifies the uncertainty associated with that estimate, leading to a higher likelihood of being correct.

Let's assume the first number to be x. Then, the second number will be 11 more than x, so the second number will be x + 11.

Thus, the two numbers can be expressed as x and x + 11.The twice the sum of the two numbers is 38. The sum of the two numbers is x + (x + 11), which is 2x + 11. So,

twice the sum of the two numbers is 2 × (2x + 11) which is equal to 4x + 22.So, we can write an equation to express this statement as 4x + 22 = 38.Subtract 22 from both sides of the equation.

4x = 16Divide both sides of the equation by 4. x = 4Thus, the first number is 4 and the second number is 11 more than 4, which is 15.The two numbers are 4 and 15.

The probability that Mrs. Vassilyeva gave birth to quadruplets, given that she gave birth to at least 3 children, is 16/69, which is closest to option A.

Out of the 69 children Mrs. Vassilyeva had, there were 16 x 2 = 32 twins, 7 x 3 = 21 triplets, and 4 x 4 = 16 quadruplets. This means that the total number of births was,

32 + 21 + 16 = 69

If we randomly select one of these births, the probability that it is a quadruplet is,

P(quadruplet) = 16/69

Given that Mrs. Vassilyeva gave birth to at least 3 children (triplets), this means that the number of possible births that could have been selected is 21 + 16 = 37. Therefore, the probability that the selected birth was a quadruplet, given that Mrs. Vassilyeva gave birth to at least 3 children, is,

P(quadruplet | at least 3 children) = P(quadruplet and at least 3 children) / P(at least 3 children)

We know that P(quadruplet and at least 3 children) is simply the probability of selecting a quadruplet, which is 16/69. To find P(at least 3 children), we need to find the probability of selecting a triplet, a quadruplet, or one of the remaining 69 - 21 - 16 = 32 births that were not triplets or quadruplets,

P(at least 3 children) = P(triplet) + P(quadruplet) + P(other births)

P(triplet) = 21/69

P(other births) = 32/69

Therefore P(at least 3 children) = 21/69 + 16/69 + 32/69 = 69/69 = 1

Plugging in these values, we get,

P(quadruplet | at least 3 children) = (16/69) / 1 = 16/69

Therefore, the answer is not one of the given options. However, the closest option is (A) 4/27, which is the same as 16/69 rounded to the nearest hundredth.

Given:

The vertices of the rectangle ABCD are A(-3,4), B(-1,4), C(-1,-1) and D(-3,-1).

It is reflected over the line x=2.

To find:

The vertices of the image A'B'C'D'.

Solution:

If a figure is reflected over the line x=a, then

\((x,y)\to (-(x-a)+a,y)\)

\((x,y)\to (-x+a+a,y)\)

\((x,y)\to (-x+2a,y)\)

The rectangle ABCD is reflected over the line x=2. So, the rule of reflection is

\((x,y)\to (-x+2(2),y)\)

\((x,y)\to (-x+4,y)\)

Using this rule, we get

\(A(-3,4)\to A'(-(-3)+4,4)\)

\(A(-3,4)\to A'(3+4,4)\)

\(A(-3,4)\to A'(7,4)\)

Similarly,

\(B(-1,4)\to B'(5,4)\)

\(C(-1,-1)\to C'(5,-1)\)

\(D(-3,-1)\to D'(7,-1)\)

The vertices of image are A'(7,4), B'(5,4), C'(5,-1) and D'(7,-1).

Answer:

\(\boxed {\tt B. \ g(2)=-68}\)

Step-by-step explanation:

We are given the function:

\(g(x)=-2x^5-4\)

We want to find g(2), so we should substitute 2 in for each x.

\(g(2)=-2(2)^5-4\)

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction. Evaluate the exponent.

\(g(2)= -2(32)-4\)

Multiply -2 and 32.

\(g(2)= -64-4\)

Subtract 4 from -64.

\(g(2)=-68\)

The correct answer is B. g(2)= -68
