Step-by-step explanation:

Given the parallelogram

Here are some of the properties of a parallelogram:

We know that the diagonals of a parallelogram bisect each other.

In our case, the diagonals PR and QS bisect each other.

Thus, we get

Given RT = x and TP = 5x-28, so

\(x = 5x-28\)

\(5x-x = 28\)

\(4x = 28\)

divide boh sides by 4

\(4x/4 = 28/4\)

\(x = 7\)

Similarly,  we can determine the value of y.

As

\(QT = TS\)

Given QT = 5y and TS = 2y+12, so

\(5y = 2y+12\)

\(5y-2y = 12\)

\(3y = 12\)

divide both sides by 3

\(3y/3 = 12/3\)

\(y = 4\)

Result

Answer:

\(y = 5x + 3\)

The population parameter will always be between lower and upper bounds of the confidence interval. - True, whereas sample statistic will always be between lower and upper bounds of the confidence interval - False

With a certain degree of certainty, the population parameter is anticipated to lie between the lower and higher limits of the confidence interval. The confidence interval, which gives an interval estimate of the unidentified population parameter, is created based on the sample data. The interval's level of confidence shows the amount of ambiguity we are prepared to accept when determining the actual population parameter.

The confidence interval's lower and upper limits may or may not be met by the sample statistic used to compute them. A single point estimate, the sample figure is susceptible to sampling error. On the other hand, based on the observed sample data and the selected degree of confidence, the confidence interval is a range of values that we can be fairly confident includes the true population parameter.

Answer: 9cm

Step-by-step explanation:

The circumference of a circle is given as: = 2πr

where,

π = 3.142

r = radius = unknown

Since circumference = 56.52cm, we'll slot it into the formula which will be:

Circumference = 2πr

2πr = 56.52

2 × 3.142 × r = 56.52

6.284r = 56.52

r = 56.52 / 6.284

r = 8.99

r = 9cm approximately

A function is a law that relates a dependent variable and an independent variable with each other

It is given that

y = 2tan (x - π/2) +3

To find the zeroes of a function that function has to be equated to zero.

2tan (x - π/2) +3 = 0

2tan (x - π/2)  = -3

tan (x - π/2)  = -3/2

x - 90 = -56.31

x = 33.69 degree

The zero of the function is at 33.69 degree

For finding the maxima /minima

Answer: 98873

Step-by-step explanation:

Using the binomial distribution, it is found that there is a 0.9815 = 98.15% probability that at least one of them has been vaccinated.

The formula is:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are:

In this problem, the values of the parameters are:

n = 5, p = 0.55

The probability that at least one of them has been vaccinated is given by:

\(P(X \leq 1) = 1 - P(X = 0)\)

In which:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 0) = C_{5,0}.(0.55)^{0}.(0,45)^{5} = 0.0185\)

Then:

\(P(X \leq 1) = 1 - P(X = 0) = 1 - 0.0185 = 0.9815\)

0.9815 = 98.15% probability that at least one of them has been vaccinated.

Answer:

Kaylaa   do you use  desmos graphing calculator?  it's an online graphsing tool and would make this very easy for you. Maybe you are not allowed to use a calculator?

Step-by-step explanation:

with out  a calculator it's a long math process,  1st because each of the equations are equal to  Y,  we can set each of them equal to each other. like this

\(\sqrt{x-8}\) + 3  =  - \((x-5)^{2}\) + 18

\(\sqrt{x-8}\)     =  - \((x-5)^{2}\)  +18 -3

\(\sqrt{x-8}\)   =    - \((x-5)^{2}\)  + 15

\(\sqrt{x-8}\)   = -[ (x-5)*(x-5) ] + 15

\(\sqrt{x-8}\)  = -[ \(x^{2}\) - 10x + 25] +15

\(\sqrt{x-8}\)  = -\(x^{2}\) + 10x -25 +15

 \(\sqrt{x-8}\) = -\(x^{2}\) + 10x -10

-  \(\sqrt{x-8}\)  = \(x^{2}\) - 10x +10

(-  \(\sqrt{x-8}\))^2  = (  \(x^{2}\)- 10x +10)^2

this turns into a 4 order polynomial.   I used a solver to find x

x = 8.75884....  approx

so the question asks what is the point at the nearest 1000th,  which is 8.759  

then they ask what is the point at the nearest 100th, which is

There are n x (n-1) number of ways for the speaker and vice speaker to be selected in the demonstrator's party, where n is the number of members in the party.

For the demonstrator's party, the first position of the speaker can be filled by any of the n members. After the speaker is chosen, there are n-1 members left to select from for the position of vice speaker. Therefore, the total number of ways the speaker and vice speaker can be selected is n x (n-1).

For example, if the demonstrator's party has 4 members, there are 4 choices for the speaker position. After the speaker is chosen, there are 3 choices left for the position of vice speaker. So, the total number of ways to select a speaker and vice speaker in the party is 4 x 3 = 12.

This formula can be applied to any size of the party to determine the total number of possible ways to select a speaker and vice speaker.

(a) To calculate the permeate composition, yp, we can use the formula:

yp = (P * x * (Ph - p₁) * t * 0) / (q * (Ph - p₁) + P * x * t * 0)

Given:

x = 0.5 (mole fraction of gas A)

Ph = 80 cm Hg (feed-side pressure)

p₁ = 20 cm Hg (permeate-side pressure)

P = 400 x 10^(-10) cm³(STP) cm/(s cm² cm Hg) (permeability)

t = 2 x 10³ cm (membrane thickness)

0 = 0.25 (fraction of feed permeated)

q = feed flow rate (to be determined)

Substituting the given values into the formula:

yp = (400 x 10^(-10) * 0.5 * (80 - 20) * 2 x 10³ * 0) / (q * (80 - 20) + 400 x 10^(-10) * 0.5 * 2 x 10³ * 0)

Since 0 * anything equals zero, we can simplify the formula to:

yp = 0

Therefore, the permeate composition, yp, is zero.

(b) To calculate the reject composition, xo, we can use the formula:

xo = 1 - yp

Since we found in part (a) that yp = 0, we can conclude that:

xo = 1 - 0

xo = 1

Therefore, the reject composition, xo, is 1.

(c) To calculate the feed flow rate, q, we can rearrange the formula from part (a) and solve for q:

q = (P * x * (Ph - p₁) * t * 0) / (yp * (Ph - p₁) + P * x * t * 0)

Substituting the given values into the formula:

q = (400 x 10^(-10) * 0.5 * (80 - 20) * 2 x 10³ * 0) / (0 * (80 - 20) + 400 x 10^(-10) * 0.5 * 2 x 10³ * 0)

Again, since 0 * anything equals zero, we can simplify the formula to:

q = 0

Therefore, the feed flow rate, q, is zero.

In conclusion:

(a) The permeate composition, yp, is zero.

(b) The reject composition, xo, is 1.

(c) The feed flow rate, q, is zero.

Please note that the calculations resulted in a feed flow rate of zero, which may suggest an inconsistency in the given values or equations. Double-checking the values and equations is recommended to ensure accuracy.

Answer:

-3,5,-10,16

Step-by-step explanation:

The temperature 60 degrees Fahrenheit is equal to 15.556 degrees Celsius.

Converting temperature from Fahrenheit to Celsius is done by subtracting 32 from the Fahrenheit temperature and then multiplying the result by 5/9. Therefore, 60 degrees Fahrenheit is equal to 15.556 degrees Celsius. This is because when you subtract 32 from 60 it gives 28. Multiplying 28 by 5/9 gives 15.556. This means that 60 degrees Fahrenheit is equal to 15.556 degrees Celsius. The Fahrenheit scale is based on 32 degrees being the freezing point of water and 212 degrees being the boiling point of water. The Celsius scale is based on 0 degrees being the freezing point of water and 100 degrees being the boiling point of water. Knowing this makes it easier to convert between the two scales, as you can use the boiling point and freezing point of water as a reference point.

The correct statement regarding the correlation coefficient (0.77) between class absences and the number of problems missed on an exam is that there is a strong positive correlation between these two variables.

A correlation coefficient ranges from -1 to 1, where values closer to -1 indicate a strong negative correlation, values closer to 1 indicate a strong positive correlation, and a value of 0 indicates no correlation. In this case, the correlation coefficient is 0.77, which is significantly close to 1.

Therefore, we can conclude that there is a strong positive correlation between class absences and the number of problems missed on an exam. This means that as the number of class absences increases, the number of problems missed on an exam also tends to increase.

Step-by-step explanation:

Two tracking stations are on the equator 173 miles apart. A weather balloon is located on a bearing of N36°E from the western station and on a bearing of N18°W from the eastern station using vector addition.

The balloon is 124.56 miles rounding to the nearest mile is option D)164 miles from the western station using vector addition.

To solve this problem, we can use the concept of vector addition. Let's denote the distance from the western station to the balloon as "x" miles.

We can split the distance between the tracking stations into two segments. The northern segment from the western station to the balloon and the southern segment from the balloon to the eastern station. The sum of these two segments should be equal to the total distance of 173 miles.

Using basic trigonometry, we can determine the lengths of the segments:

In the northern segment:

sin(36°) = (x) / (173)

x = 173 * sin(36°) ≈ 103.87 miles

In the southern segment:

sin(18°) = (173 - x) / (173)

173 - x = 173 * sin(18°) ≈ 48.44 miles

x ≈ 173 - 48.44 ≈ 124.56 miles

Therefore, the balloon is approximately 124.56 miles away from the western station. Rounding to the nearest mile, the correct answer is D) 164 miles.
