Answer:

Step-by-step explanation:

You want the measure of angle S opposite angle (4x+5)° in an inscribed quadrilateral in which the other two angles are (5x-2)° and (7x+2)°.

The measure of an inscribed angle is half the measure of the arc it intercepts.

Two opposite angles in an inscribed quadrilateral intercept arcs that total the full circle.  Since the sum of double those angles is 360°, the sum of opposite angles of an inscribed quadrilateral is 180°—they are supplementary.

We can use this to find the value of x:

  (5x -2)° +(7x +2)° = 180°

  12x = 180 . . . . . . simplify

  x = 15 . . . . . . . divide by 12

Now, the angle opposite S can be found to be ...

  (4x +5)° = (4·15 +5)° = 65°

Angle S is the supplement of this:

  S = 180° -65°

  S = 115°

Answer:

The length of line segment CD is 10.3 units (rounded to 2 decimal places).

Step-by-step explanation:

To find the length of line segment CD, we need to use the distance formula, which is:

Distance = √[(x2 - x1)^2 + (y2 - y1)^2]

Here, (x1, y1) = (1, -5) and (x2, y2) = (6, 4).

So, substituting these values in the distance formula, we get:

Distance = √[(6 - 1)^2 + (4 - (-5))^2]

= √[5^2 + 9^2]

= √(25 + 81)

= √106

≈ 10.3 (rounded to 2 decimal places)

Therefore, the length of line segment CD is 10.3 units (rounded to 2 decimal places).

75 % of the college students will take more than 4.25 minutes when trying to find a parking spot in the library parking lot.

Actual experiments and sufficient documentation of the occurrence of occurrences serve as the foundation for experimental probability, sometimes referred to as empirical probability. A number of real experiments are carried out in order to ascertain the likelihood of any event. Random experiments are studies that don't have a predetermined outcome. The results of such tests are unpredictable. The chance of random experiments is calculated repeatedly. A trial is a repeating of an experiment that is performed a certain number of times.

Given that, mean of 3.5 minutes and a standard deviation of 1 minute.

Now, for 75% we have:

P(X > x) = 0.75

The z-score is given by:

0.75 = (X - μ) / σ

Substituting the formula we have:

0.75 = (X - 3.5) / 1

0.75 = X - 3.5

X = 0.75 + 3.5 = 4.25.

Answer:

To solve this problem, we can use the formula for exponential decay:

m = m0(1 - r)^t

where:

m0 = initial mass (300 grams)

r = decay rate (6% per day, or 0.06)

t = time in days

We want to find the mass at the beginning of the 16th day, so t = 15:

m = 300(1 - 0.06)^15

m ≈ 107.4

Therefore, the mass of the radioactive sample at the beginning of the 16th day of the experiment is approximately 107.4 grams.

Answer:

72mph

Step-by-step explanation:

To convert km/hr into m/s, simply multiply the speed value by 5/18

To convert 8Km/hr to m/s, multiply 8 by 5/18 or divide by 3.6

8 x 5/18 = 2.22m/s

You can say that 2.22m/s = 5mph since 8km/hr = 5mph

If 2.2m/s =5mph, 1m/s = 5mph/ 2.2 (Divide both sides by 2.2)

Then 32m/s = 5mph/2.2 x 32

2.25 x 32 = 72 mph

Using the conversion, 32 m/s is equivalent to 72 mph.

We have,

To convert 32 m/s to mph using the conversion factor 8 km/h = 5 mph,

We can follow these steps:

- Convert 32 m/s to km/h by multiplying by the conversion factor:

32 m/s x (3.6 km/h / 1 m/s) = 115.2 km/h

- Convert 115.2 km/h to mph using the conversion factor 8 km/h = 5 mph:

115.2 km/h x (5 mph / 8 km/h) = 72 mph

The volume of the hemisphere with diameter 9 is approximately 76.0435 cubic units.

What is hemisphere ?

A hemisphere is a three-dimensional geometric shape that consists of half of a sphere. It is formed by slicing a sphere into two equal parts along a plane that passes through its center. The term "hemisphere" comes from the Greek words "hemi," meaning half, and "sphaira," meaning sphere.

A hemisphere has a curved surface that is a portion of a sphere's surface, as well as a flat circular base that is formed by the plane of the cut. The diameter of the base is equal to the diameter of the original sphere, and the radius is half of the diameter.

To find the volume of the hemisphere, we first need to know its formula. A hemisphere is half of a sphere, so its volume is half of the volume of a sphere with the same radius.

The formula for the volume of a sphere is:

V = (4/3)πr³

where V is the volume and r is the radius.

Since the hemisphere has diameter 9, its radius is half of the diameter, which is:

r = 9/2 = 4.5

Substituting the value of r in the formula for the volume of a sphere, we get:

V = (4/3)π(4.5)³

V = (4/3)π(91.125)

V = 152.087

Since the hemisphere is half of a sphere with radius 4.5, its volume is half of the volume of that sphere, which is:

V_hemisphere = (1/2)V_sphere

V_hemisphere = (1/2)(4/3)π(4.5)³

V_hemisphere = 76.0435

Therefore, the volume of the hemisphere with diameter 9 is approximately 76.0435 cubic units.

Answer:

1/2 of the pool is filled, and in the second situation, the entire pool is filled.

Step-by-step explanation:

Let's start by finding the hourly filling rate of each pump. The first pump can fill the pool in 4 hours, so its hourly rate is 1/4 of the pool. The second pump can fill the pool in 6 hours, so its hourly rate is 1/6 of the pool.

For the first situation, the first pump works for 2 hours, so it fills 2/4 or 1/2 of the pool. The second pump does not work in this situation, so it fills 0 of the pool. Therefore, the total amount of the pool filled is 1/2.

For the second situation, the first pump works for 2 hours and fills 1/2 of the pool. The second pump works for 3 hours and fills 3/6 or 1/2 of the pool. Therefore, the total amount of the pool filled is 1/2 + 1/2 = 1.

So, in the first situation, 1/2 of the pool is filled, and in the second situation, the entire pool is filled.

The value of r(s(4)) is -33.

What is a function?

In mathematics, a function is a relation between a set of inputs (the domain) and a set of possible outputs (the codomain) with the property that each input is related to exactly one output.

To find the value of r(s(4)), we first need to find the value of s(4), and then use that as the input for the function r.

To find s(4), we substitute x = 4 into the expression for s(x):

s(4) = 3(4) - 1 = 12 - 1 = 11

Now that we have the value of s(4), we can use it as the input for the function r:

r(s(4)) = r(11) = -3(11) = -33

(a) The exploratory factor analysis (EFA) can be useful in two ways: Dimensional Reduction: The dimensionality of a set of data can be reduced by exploratory factor analysis. Rather than dealing with several variables, it identifies the basic factors that describe the data set. This can be achieved by extracting factor information that shows the covariance structure of the variables that underlie the observations. Investigation of latent variables: Exploratory factor analysis can be used to determine whether an underlying dimension, such as depression or anxiety, underlies a collection of observable variables, such as feelings of depression, nervousness, or irritability. Latent variables are those that cannot be observed directly. (b) Factor analysis and principal component analysis are two techniques for data reduction that are frequently confused. The principal component analysis, on the other hand, is a technique that creates uncorrelated variables to replace the original variables. It can be viewed as a special case of factor analysis in which all of the extracted factors are used. It includes the raw data's total variance, which is defined by a few components. Principal component analysis is a method of data reduction that extracts uncorrelated factors from the original variables. The correlation structure of the original variables is utilized in factor analysis to define the underlying factors.

The answer of the given question based on perimeter of trapezoid the ratio will be  x:y is 8:5.

A trapezoid is quadrilateral with at least one pair of the parallel sides. The parallel sides are called  bases of  trapezoid, and  non-parallel sides are called legs.

Let's denote the lengths of the four sides of Trapezoid 1 as a, b, c, and d, and the lengths of the corresponding sides of Trapezoid 2 as m, n, p, and q, respectively. Then we have:

a + b + c + d = 240 (perimeter of Trapezoid 1)

m + n + p + q = 150 (perimeter of Trapezoid 2)

Since Trapezoid 1 and Trapezoid 2 are similar, we can write:

m = ax

n = bx

p = cy

q = dy

where x and y are the ratios of the longer and shorter bases of Trapezoid 1 to Trapezoid 2, respectively.

Substituting these expressions into the equations for the perimeters of the trapezoids, we get:

a(x+y) + b(x+y) + c(x+y) + d(x+y) = 240

(ax+bx+cy+dy) = 150

Simplifying these equations, we get:

(a+b+c+d)(x+y) = 240

(a+b+c+d)(x+y)(x/y) = 150

by Dividing  second equation by  first, we will get:

x/y = 240/150 = 8/5

Therefore, the ratio x:y is 8:5.

Let number of hours the bakery needs to operate in order to make back the amount it invested in equipment be = "h".

To find "h", we need to find the profit per hour,

The profit per hour is = difference between hourly receipts and hourly operating costs;

Profit per hour = Hourly receipts - Hourly operating costs

Profit per hour = $10 - $9

Profit per hour = $1

The total profit required to make back the $392 investment is = $392,

We know that,

⇒ Total profit = (Profit per hour) × (Number of hours)

⇒ $392 = $1 × h

⇒ h = $392/$1

⇒ h = 392

So, bakery needs to operate for 392 hours to make back the amount it invested in equipment.

To calculate the total expenses and receipts, we can use the following formulas:

⇒ Total expenses = (Operating costs) × (Number of hours)

⇒ Total expenses = $9 × 392

⇒ Total expenses = $3528

⇒ Total receipts = (Hourly receipts) × (Number of hours)

⇒ Total receipts = $10 × 392

⇒ Total receipts = $3920
