Answer:

27°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

let the third angle be x , then

x + 90° + 63° = 180°

x + 153° = 180° ( subtract 153° from both sides )

x = 27°

Answer:

27 degrees

Step-by-step explanation:

A right angled triangle has 1 angle as 90 degree. And as you know the other angle is 63 degree, and the angle sum property of a triangle is 180 degrees. So-

Let's take 'x' as the other angle.

90 + 63 + x = 180

153 + x = 180

x = 180 - 153 = 27

x = 27 degrees

So, the other angle is 27 degrees.

All the angles of the right-angled triangle are- 90, 63, 27.

The percentile rank of 30 is 64.3% and the percentile rank of 15 is 0%.

To calculate the percentile rank of 30 and 15 from the given data, we need to first arrange the data in ascending order:

1, 15, 15, 15, 16, 22, 23, 23, 27, 30, 35, 43, 44, 45

To find the percentile rank of a particular value (X), we use the following formula:

Percentile rank of X = (Number of values below X / Total number of values) x 100%

For X = 30:

Number of values below X = 9

Total number of values = 14

Therefore,

Percentile rank of 30 = (9/14) x 100% = 64.3%

For X = 15:

Number of values below X = 0

Total number of values = 14

Therefore,

Percentile rank of 15 = (0/14) x 100% = 0%

Step-by-step explanation: If you were to graph this rectangle, you would see that D has the same x as A and the same y as C

A circle is the locus of points in a plane that are equidistant from one point, known as the center.

In geometry, a circle is a two-dimensional figure that consists of all points in a plane that are at an equal distance, called the radius, from a fixed point called the center. The distance from the center to any point on the circumference of the circle is always the same.

This property makes circles useful in various fields, such as mathematics, physics, and engineering. Circles have several important characteristics, including a diameter (the longest chord that passes through the center), a circumference (the boundary of the circle), and an area (the measure of the space enclosed by the circle).

The equation of a circle in the Cartesian coordinate system is (x - a)^2 + (y - b)^2 = r^2, where (a, b) represents the center coordinates and r represents the radius of the circle.

The total amount of yards are 4(1/8).

To find the total amount of fabric Tanya used, we need to add the amount of fabric she used for the dress and the amount of fabric she used for the jacket.

Tanya used 3(3/8) yards of fabric for the dress and 1(1/3) yards of fabric for the jacket. We can add these two amounts by finding a common denominator for the fractions and adding the whole numbers:

3(3/8) + 1(1/3) = 3(9/24) + 1(8/24)

=> 3(17/24)

Therefore, Tanya used a total of 3(17/24) yards of fabric. This can be simplified to:

=> 3(17/24) = 4(1/8)

So the answer is A. 4(1/8).

The midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is 9980

The midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is calculated by summing the area of each subinterval under the midpoint of the interval.

The formula for the midpoint Riemann sum is given by:

Sum = (width of interval) * (height of midpoint)

For this problem, since the width of each interval is 16/4 = 4, the midpoint Riemann sum is calculated by:

Sum = 4 * (1 + (16/4)^3 + (32/4)^3 + (48/4)^3)

Substituting the values for each midpoint, we get the following equation:

Sum = 4 * (1 + 4^3 + 8^3 + 12^3)

This simplifies to:

Sum = 4 * (1 + 64 + 512 + 1728)

Therefore, the midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is:

Sum = 4 * (2495)

Sum = 9980

Please find attached the drawing of two triangles which are drawn with MS Word, based on the possible difference of two triangles having a ASA and a SAA configuration.

Unique triangles are triangles that are different based on their configuration, which derives from the positioning of the given parameters to correspond with different congruency requirement.

The conditions for the congruency of two triangles are;

SSS: The Side-Side-Side rule; two triangles are congruent if all three sides of one triangle are congruent to the three sides of the other triangle

SAS: The Side-Angle-Side rule; two triangles are congruent if two sides and the included angle of one are congruent to two sides and an included angle in the other triangle

ASA: The Angle-Side-Angle rule; two triangles are congruent if two angles and the included side of one triangle are congruent to two angles and an included side of the other triangle

SAA: The Side-Angle-Angle rule; Two triangles are congruent if two angles and an a non included side of one triangle are congruent to two angles and the non included side of the other triangle.

RHS: Right angle Hypotenuse Side: Two right triangles are congruent if the hypotenuse side and one leg of one triangle are congruent to the hypotenuse side and one leg of the other right triangle.

To test the hypothesis that the mean weight of two sheets is equal (μ1 - μ2) against the alternative that it is not, and assuming equal variances, we can use a two-sample t-test. The t-statistic can be calculated using the following formula:

t = (x1 - x2) / (s_p * sqrt(1/n1 + 1/n2))

where:

x1 and x2 are the sample means of the two sheets,

s_p is the pooled standard deviation,

n1 and n2 are the sample sizes.

The pooled standard deviation (s_p) can be calculated using the following formula:

s_p = sqrt(((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2))

where:

s1 and s2 are the sample standard deviations.

To calculate the t-statistic, we need the sample means, sample standard deviations, and sample sizes.

Once you provide the specific values for these variables, I can assist you in calculating the t-statistic to 3 decimal places.

To test the hypothesis that the mean weight of the two sheets is equal (μ1 - μ2) against the alternative that it is not, we can use a paired t-test assuming equal variances. The paired t-test is used when we have paired data or measurements on the same subjects or objects.

The t-statistic for a paired t-test is calculated as follows:

t = (X1 - X2) / (s / √n)

where X1 and X2 are the sample means of the two samples, s is the pooled standard deviation, and n is the number of pairs.

To calculate the probability that at least two people in a class of 30 share the same birthday, we can use the complement rule, which states that the probability of an event happening is equal to one minus the probability of the event not happening.

If we assume that birthdays are uniformly distributed throughout the year (i.e., each day is equally likely to be someone's birthday), then the probability that no two people in the class share the same birthday is:

365/365 * 364/365 * 363/365 * ... * 336/365

This is because the first person can have any birthday (probability of 365/365), the second person must have a different birthday (probability of 364/365), the third person must have a different birthday than the first two (probability of 363/365), and so on, up to the 30th person, who must have a different birthday than the first 29 (probability of 336/365).

Calculating this probability gives us:

(365/365) * (364/365) * (363/365) * ... * (336/365) ≈ 0.2937

So the probability that no two people in the class share the same birthday is approximately 0.2937.

Using the complement rule, the probability that at least two people in the class share the same birthday is:

1 - 0.2937 = 0.7063

Therefore, the probability that at least two people in a class of 30 share the same birthday is approximately 0.7063, or 70.63%.

Answer:

26 units

Step-by-step explanation:

If point F is on the line segment EG, then EF+FG = EG

Given

FG=8,

EF=2x+4

EG=4x−10

Substitute the given values into the formula;

2x+4+8 = 4x−10

2x+12 = 4x-10

collect like terms

2x-4x = -10-12

-2x = -22

x = 22/2

x =11

Since EF = 2x+4

EF = 2(11)+4

EF = 22+4

EF = 26

Hence the numerical length of EF is 26 units

the current in the electromagnet is approximately 0.019 A (amps).

What is Magnetic Field in a Solenoid?

A solenoid is a cylindrical coil of wire that is often used to generate a magnetic field. When an electric current flows through the wire, it creates a magnetic field around the solenoid. The magnetic field produced by a solenoid can be calculated using the following formula:

B = μ₀ * n * I

To find the current in the solenoid, we can use a formula that relates the magnetic field (B) to the current (I) and other characteristics of the solenoid. The formula is:

B = μ₀ * (N * I) / L

Where:

B is the magnetic field strength,

μ₀ is the permeability of free space (constant value),

N is the number of turns (loops) in the solenoid,

I is the current in the solenoid and

L is the length of the solenoid.

We can rearrange the formula to solve for current (I):

I = (B * L) / (μ₀ * N)

Now we put the given values ​​into the formula:

B = 9.4 × 10⁻⁵ T (given)

L = 13 cm = 0.13 m (converted to meters)

N = 280 (given)

μ₀ is a constant with a value of 4π × 10⁻⁷ T·m/A

I = (9.4 × 10⁻⁵ T * 0.13 m) / (4π × 10⁻⁷ T·m/A * 280)

Now we can calculate the current:

I ≈ 0.019 A

Rounded to two significant figures, the current in the electromagnet is approximately 0.019 A (amps).

Weighing the available information and assigning a probability.

A sort of probability called subjective probability is one that is based on a person's subjective assessment or personal knowledge of the likelihood of a particular result. It solely represents the subject's thoughts and prior experience and does not include any formal computations. A "gut instinct" used when making a deal is an illustration of subjective probability.

So, as per the definition of subjective probability

Dividing the number of favourable events by the number of possible events and Studying the fraction of times in the past a particular event has happened, both can be determined through calculations mathematically accurate but for Weighing the available information and assigning a probability we might use a "gut instinct".

Answer:

9

Step-by-step explanation:

Let the number be 'x'

One third of a number : (1/3) *x

Thrice the number = 3x

\(3x -24=\dfrac{1}{3}x\\\\3x - \dfrac{1}{3}x = 24\\\\\\\)

Multiply the entire equation by 3

9x - x =  72

8x = 72

Divide both sides by 8

x = 72/8

x = 9

Answer:

The last graph is your answer.

Step-by-step explanation:

The midline of the function should be in between the highest and lowest y value.

Here's the midline should be at y=-1

Let find where our zeroes occur at

\(2 \cos(2x - \frac{\pi}{3} ) - 1 = 0\)

\(2 \cos(2x - \frac{\pi}{3} ) = 1\)

\( \cos(2x - \frac{\pi}{3} ) = \frac{1}{2} \)

Take the inverse cosine of both sides

\(2x - \frac{\pi}{3} = \cos {}^{ - 1} ( \frac{1}{2} ) \)

\(2x - \frac{\pi}{3} = \frac{\pi}{3} + 2\pi(n)\)

Or

\(2x - \frac{\pi}{3} = \frac{5\pi}{3} + 2\pi(n)\)

Solve for x. in both scenarios

\(x = \frac{\pi}{3} + \pi(n)\)

\(x = \pi + \pi(n)\)

So our zeroes occur at pi/3, and pi, and every pi units. So we should have a period of pi, and zeroes at pi/3, pi

The last graph is your answer.

Using the fact that the opposite sides of a trapezoid are parallel, we can set up the following equation:

2x + 15 = 3x + 10

Simplifying this equation, we get:

x = 5

Therefore, the value of x is 5.

To find the value of x, we use the fact that the opposite sides of a trapezoid are parallel. In this case, side AD is parallel to side BC. We also know that angles BCD and CDA are supplementary (they add up to 180 degrees) because they are adjacent angles that form a straight line.

Using this information, we can set up the equation 2x + 15 = 3x + 10, which represents the fact that the lengths of the two parallel sides and the length of the diagonal are related. Solving for x, we get x = 5. Therefore, the value of x is 5.
