The measure of the required angle of the given rhombus ABCD is m∠ADC = 64°.

The given rhombus has four angles as

∠ADC, ∠DCB, ∠CBA, and ∠BAD

It has two diagonals that bisect each other at point E.

And we have ∠ABD = 32° and ∠ACD = 58°

Here, the angles ∠ABD and ∠BDC are alternate angles. Since we know that, the alternate angles are equal in measure, we can write

∠ABD = ∠BDC

⇒ 32° = ∠BDC

Since we know that the diagonals of a rhombus bisect the angles, we get

∠ADC = 2∠BDC

⇒ ∠ADC = 2 × 32° = 64°

Therefore,  the required angle of the rhombus is ∠ADC = 64°.

The reflection of triangle with respect to y axis is P'(-3,-2). Q'(1, -2), R'(-2,7)

How does reflection relate to the y axis?

The y-coordinate stays the same when a point is reflected across the y-axis, but the x-coordinate is assumed to be the additive inverse. Point (x, y) is reflected across the y-axis as (-x, y).

What does a reflection mean in mathematics?

A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.

For the reflection we need to see first the axis then we will fix that coordinate of the axis like in this case we have y axis so y coordinates will be fix and for x coordinate we will do in opposite direction like for 3 it will be -3 , for -1 it will be 1 and for 2 it will be -2

Answer:

Measures are SV=9 units., SY=14 units, YW= [tex]\sqrt{75units}[/tex], YW=[tex]\sqrt{27units}[/tex]

Step-by-step explanation:

===================================================

Explanation:

The circumcenter is found by intersecting the perpendicular bisectors of the triangle.

Segments VY, WY, and XY are perpendicular bisectors of triangle STU.

A perpendicular bisector has two properties:

Perpendicular bisector WY divides side TU into equal pieces TW and WU

In short:

TW = WU

So

TW = 11

since WU is equal to 11 as well

---------------------------------------

Focus on triangle TWY.

This is a right triangle with the sides of...

We'll use the pythagorean theorem to determine the unknown leg.

Plug in a = 11 and c = 14. Then let's solve for b.

[tex]a^2+b^2 = c^2\\\\11^2+b^2 = 14^2\\\\121+b^2 = 196\\\\b^2 = 196-121\\\\b^2 = 75\\\\b = \sqrt{75}\\\\b \approx 8.66025\\\\b \approx 8.7\\\\[/tex]

Therefore, segment YW is roughly 8.7 units.

The variables as length are L and width is W and the system of equations is L = 2W - 3 and 42 = 2(L + W) and the length and width are 13 feet and 8 feet respectively.

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

As per the given total fencing = 42 feet

Let's say the length is L and the width is W.

As per the given,

L = 2W - 3

Perimeter = 2(length + width)

42 = 2(L + W)

21 = 2W - 3 + W

21 + 3 = 3W

W = 8 feet

And, L = 2(8) - 3 = 13 feet

Hence "The variables as lengths are L and width is W and the system of equations is L = 2W - 3 and 42 = 2(L + W) and the length and width are 13 feet and 8 feet respectively".

Answer: 8 + i

Step-by-step explanation:

The complex number 8/1+i can be written in standard form as 8 + i. In standard form, a complex number is written as a+bi, where a is the real part and bi is the imaginary part. In this case, the real part is 8 and the imaginary part is i. Therefore, the standard form of the complex number 8/1+i is 8 + i.

Answer: 4-4i

The answers to each part are as follows -

a. n refers to the number of bought tickets. p is representative of the probability that I will win some prize after taking a single ticket.

b. The values of X will be in the range 0 to 5. It is indicative of number of won tickets. Hence, values that are possible are 0, 1, 2, 3, 4 and 5.

c. The probability of each value of x will be calculated using Binomial formula. The formula is-

P(x) = (n choose x) × [tex] {p}^{x} [/tex] × [tex] {(1 - p)}^{n - x} [/tex]

In this formula, n is the number of trials, p is probability of success and x is number of successes.

Keep the values in formula for calculation -

P(0) = (5 choose 0) * 0.256^0 * (1-0.256)^(5-0)

P(0) = 0.326

P(1) = (5 choose 1) * 0.256^1 * (1-0.256)^(5-1)

P(1) = 0.410

P(2) = (5 choose 2) * 0.256^2 * (1-0.256)^(5-2)

P(2) = 0.219

P(3) = (5 choose 3) * 0.256^3 * (1-0.256)^(5-3)

P(3) = 0.062

P(4) = (5 choose 4) * 0.256^4 * (1-0.256)^(5-4)

P(4) = 0.011

P(5) = (5 choose 5) * 0.256^5 * (1-0.256)^(5-5)

P(5) = 0.001

d. For the probability histogram stating the distribution of x, the x-axis will have x values and y-axis will have the probability of each x value. The mean of distribution will be calculated by the formula -

mean = n × p

mean = 5 × 0.256

mean = 1.28

Further, the standard deviation will be calculated by the formula -

Standard Deviation = [tex] \sqrt{n × p × (1-p)} [/tex]

90 miles per hour is 132 feet per second. To convert multiply it by 5,280, then divide by 3,600. The foot per second is a speed and velocity unit.

Mile per hour is a speed unit defined in the Imperial and US customary systems of measurement. It calculates how many miles an object travels in an hour. The international mile [mi] is a length unit that is equivalent to 5280 feet and precisely defined as 1609.344 metres. The abbreviation mph is more commonly used on signs and labels, but in science and engineering contexts, mi/h may be more convenient for unit arithmetic.

The Imperial and US customary systems of units define the foot per second as a unit of speed. It calculates the distance an object travels in one second. The foot [ft] is a length unit that is precisely defined as 0.3048 metres.

To convert a speed value from miles per hour to feet per second, multiply it by 5,280, then divide by 3,600.

Speed in miles per hour = 90 miles per hour

From the given information,

"The population of a city decreases by 3.3% per year"

and

This year's population is 72,000

Thus,

The population of the following year will be

Next year population = 72000 - 3% of 72000

Next year population = 72000 - 3% × 72000

Next year population = 72000 - 0.03 × 72000

If we reject the null hypothesis, we conclude that there is not enough statistical evidence to infer that the null hypothesis is true.

In hypothesis testing, the researcher makes a claim about the population and then uses a sample of the population to determine whether or not the claim is accurate. Before the sample is drawn, the degree of significance—or the predicted error—must be determined. The validity of a claim is determined by the value of a test statistic.

The researcher rejects the provided null hypothesis if the test statistic's value is significant. When the null hypothesis is rejected, there is no discernible difference between the hypothesized value and the sampled observations. If the null hypothesis is rejected, it is determined that there is insufficient statistical support to draw the conclusion that it is true.

r = n[(A/P)1/nt - 1]

r = 1 × [(38,000.00/22,000.00)1/(1)(9) - 1]

Step-by-step explanation:

For the linear factors of the cubic, which are (x - 2)(x - 3)(x – 5), the function will be f(x)=1/6x³–5/3x²+31/6x–5.

The first-degree equations that make up a polynomial's linear factors serve as the foundation for higher-order and more complicated polynomials. The formula for a linear factor is ax + b, and it cannot be factored further. A linear factor model establishes a linear equation-based relationship between the return on an asset (such as a stock, bond, mutual fund, or other type of investment) and the values of a small number of factors.

Here,

The linear factors of the cubic are  

=(x – 2)(x – 3)(x – 5)

To solve for the leading coefficient, use  

–5 = a(0 – 2)(0 – 3)(0 – 5)

a = 1/6

f(x)=1/6x³–5/3x²+31/6x–5
