Answer:

magnitude of PÔS = 60°

magnitude of SÔQ = 120°

note: a straight line has always 180°

solve for x:

m∠POS

m∠SOQ

So to find angle POS and SOQ we have to find value of x first.

\( \\ \)

\( \rm \angle POS + \angle SOR + \angle ROQ = 180 \degree \\ \)

Reason:-

Sum of angles on same line.

By the way it can be any number of angles but they should meet at same point. And their sum is always 180°. Remember linear pair? It is also same aspect but there will be only two angles.

\( \\ \)

So:-

\( \\ \)

\( \dashrightarrow \sf \angle POS + \angle SOR + \angle ROQ = 180 \degree \\ \)

\( \\ \)

\( \dashrightarrow \sf 3x + 2x+ 80= 180 \degree \\ \)

\( \\ \)

\( \dashrightarrow \sf 5x+ 80= 180 \degree \\ \)

\( \\ \)

\( \dashrightarrow \sf 5x= 180 - 80 \degree \\ \)

\( \\ \)

\( \dashrightarrow \sf 5x= 100 \degree \\ \)

\( \\ \)

\( \dashrightarrow \sf x= \dfrac{100}{5} \degree \\ \)

\( \\ \)

\( \dashrightarrow \sf x= \dfrac{5 \times 20}{5} \degree \\ \)

\( \\ \)

\( \dashrightarrow \sf x= \dfrac{\cancel5 \times 20}{\cancel5} \degree \\ \)

\( \\ \)

\( \dashrightarrow \sf x= \dfrac{1 \times 20}{1} \degree \\ \)

\( \\ \)

\( \dashrightarrow \bf x=20\degree \\ \)

\( \\ \\ \)

\( \\ \)

\( \dashrightarrow \sf 3x + 2x+ 80= 180 \degree \\ \)

Put value of x

\( \\ \)

\( \dashrightarrow \sf( 3 \times 20) + (2 \times 20)+ 80= 180 \degree \\ \)

\( \\ \)

\( \dashrightarrow \sf60 + (2 \times 20)+ 80= 180 \degree \\ \)

\( \\ \)

\( \dashrightarrow \sf60 + 40+ 80= 180 \degree \\ \)

None of the statements A, B, or C can be determined to be true based on the given information. we do not have enough information to determine the values of P(A), P(A∩B), or P(B|A) from the given probabilities.

To determine which statement is true, let's analyze the given information.  We have:

P(B) = 4/1

P(A∪B) = 2/1

P(A|B) = 3/2

Let's evaluate each statement:

A) P(A) = 3/1

This statement is not directly supported by the given information. We cannot determine the value of P(A) solely based on the provided probabilities.

B) P(A∩B) = 12/1

This statement is also not supported by the given information. We do not have enough information to determine the value of P(A∩B).

C) P(B|A) = 5/1

This statement is not supported by the given information. We do not have any direct information about P(B|A), so we cannot determine its value.

D) A and B are not independent.

To determine whether A and B are independent, we can check if P(A∩B) = P(A) * P(B). However, as mentioned earlier, we do not have enough information to determine the value of P(A∩B). Therefore, we cannot conclude whether A and B are independent based on the given information.

In summary, none of the statements A, B, or C can be determined to be true based on the given information. The only conclusion we can draw is that we do not have enough information to determine the values of P(A), P(A∩B), or P(B|A) from the given probabilities.

Answer:

the median home size.

Step-by-step explanation:

In this scenario, the confounding variable would be the median home size. This is because this factor is both a cause and effect of the median home prices. A bigger house would obviously be worth more than a smaller house so the house size affects the prices of the homes in the market. At the same time, the median home sizes can also cause an increase or decrease in crime rates as criminals are more likely to target homes that seem as though they have more valuables inside.

For the matrix the true statement is given by option d. Both A and B are false.

Let's analyze each statement of the matrix as follow,

A) If A is a 3 times 5 matrix and T is a transformation defined by T(x) = Ax, then the domain of T is R⁵.

This statement is false.

The domain of the transformation T is not R⁵.

The domain of T is determined by the dimensionality of the vectors x that can be input into the transformation.

Here, the matrix A is a 3 times 5 matrix, which means the transformation T(x) = Ax can only accept vectors x that have 5 elements.

Therefore, the domain of T is R⁵, but rather a subspace of R⁵.

B) If A is a 3 times 2 matrix, then the transformation x right arrow Ax cannot be onto.

This statement is also false.

The transformation x → Ax can still be onto (surjective) even if A is a 3 times 2 matrix.

The surjectivity of a transformation depends on the rank of the matrix A and the dimensionality of the vector space it maps to.

It is possible for a 3 times 2 matrix to have a rank of 2,

and if the codomain is a vector space of dimension 3 or higher, then the transformation can be onto.

Therefore, as per the matrix both statements are false, the correct answer is d. Both A and B are false.

The correct statement is Most of the songs were between 3 minutes and 3.8 minutes long.

Based on the given information from the graph, we can determine the following:

The graph shows an upward trend from 2.8 to 3.4 on the horizontal axis.

Then, there is a downward trend from 3.4 to 4 on the horizontal axis.

From this, we can conclude that most of the songs played during the one-hour interval were between 3 minutes and 3.8 minutes long. This is because the upward trend indicates an increase in length from 2.8 to 3.4, and the subsequent downward trend suggests a decrease in length from 3.4 to 4.

Therefore, the correct statement is:

The phase angle between the current and voltage in a pure resistive circuit is 0 radians.

How to determine the answer:In a pure resistive circuit, the phase angle between current and voltage is \(0\) radians.

This is because a pure resistive circuit has a voltage and a current in the same phase, which implies that the two are in phase.

To understand this, let's look at the two main parts of the question: a pure resistive circuit and the phase angle between current and voltage.

A pure resistive circuit is a circuit in which the only element is a resistor.

This means that the circuit does not contain any inductors or capacitors and, as a result, does not have any phase shift in the current or voltage.

The phase angle between current and voltage is the angle between the current and voltage waveforms in a circuit.

The angle is measured in radians and is positive for capacitive circuits and negative for inductive circuits.

In conclusion, the phase angle between current and voltage in a pure resistive circuit is \(0\) radians.

Multiply the fractional part of the decimal number by 2 and keep track of the integral parts:

0.8542 * 2 = 1.7084 (integer part: 1)

0.7084 * 2 = 1.4168 (integer part: 1)

0.4168 * 2 = 0.8336 (integer

To convert 326.5 from Octal to Binary:

The octal number 326.5 can be converted to decimal first.

3 * 8^2 + 2 * 8^1 + 6 * 8^0 + 5 * 8^(-1)

3 * 64 + 2 * 8 + 6 * 1 + 5 * (1/8)

192 + 16 + 6 + 0.625

214.625 (in decimal)

Now, let's convert 214.625 from decimal to binary:

The integer part, 214, can be converted to binary by successive division by 2:

214 / 2 = 107 (remainder 0)

107 / 2 = 53 (remainder 1)

53 / 2 = 26 (remainder 1)

26 / 2 = 13 (remainder 0)

13 / 2 = 6 (remainder 1)

6 / 2 = 3 (remainder 0)

3 / 2 = 1 (remainder 1)

1 / 2 = 0 (remainder 1)

Reading the remainders from bottom to top gives us the binary representation of the integer part: 11010110.

The fractional part, 0.625, can be converted to binary by successive multiplication by 2:

0.625 * 2 = 1.25 (integer part: 1)

0.25 * 2 = 0.5 (integer part: 0)

0.5 * 2 = 1.0 (integer part: 1)

Reading the integer parts from top to bottom gives us the binary representation of the fractional part: 101.

Combining the binary representation of the integer and fractional parts, we get:

326.5 (in octal) = 11010110.101 (in binary)

To convert 3A15 from Hexadecimal to Octal:

First, convert the hexadecimal number to decimal:

3A15 = 3 * 16^3 + 10 * 16^2 + 1 * 16^1 + 5 * 16^0

= 3 * 4096 + 10 * 256 + 1 * 16 + 5 * 1

= 12288 + 2560 + 16 + 5

= 15029 (in decimal)

Convert the decimal number 15029 to octal:

Divide 15029 by 8 successively:

15029 / 8 = 1878 (remainder 5)

1878 / 8 = 234 (remainder 6)

234 / 8 = 29 (remainder 2)

29 / 8 = 3 (remainder 5)

3 / 8 = 0 (remainder 3)

Reading the remainders from bottom to top gives us the octal representation:

3A15 (in hexadecimal) = 35625 (in octal)

The correct option would be "None of these" since the projection is an ellipse and not any of the given options (2, 4, 16, or "This option").

To determine the projection of the region D onto the xy-plane, we need to find the intersection curve of the two paraboloids.

First, let's set the two equations equal to each other:

3x² + (12/24)y² = 16 - x²

Next, we simplify the equation:

4x² + (12/24)y² = 16

Multiplying both sides by 24 to eliminate the fraction:

96x² + 12y² = 384

Dividing both sides by 12 to simplify further:

8x² + y² = 32

Now, we can see that this equation represents an elliptical shape in the xy-plane. The equation of an ellipse centered at the origin is:

(x²/a²) + (y²/b²) = 1

Comparing this with our equation, we can deduce that a² = 4 and b² = 32. Taking the square root of both sides, we have a = 2 and b = √32 = 4√2.

So, the semi-major axis is 2 and the semi-minor axis is 4√2. The projection of region D onto the xy-plane is an ellipse with a major axis of length 4 and a minor axis of length 8√2.

Answer:

Step-by-step explanation:

The critical z value for a 90% confidence interval for the population proportion is 1.645.

The point estimate of p, the population proportion, is 0.36 (27/75).
To find the critical z value for a 90% confidence interval for the population proportion, we use a z-table or calculator. The formula for the z-score is:
z = (x - μ) / (σ / √n)
where x is the sample proportion, μ is the population proportion (which is unknown), σ is the standard deviation (which is also unknown), and n is the sample size.
Since we don't know the population proportion or standard deviation, we use the sample proportion and standard error to estimate them. The standard error is:
SE = √[p(1-p) / n]
where p is the sample proportion and n is the sample size.
Using the values given in the question, we have:
SE = √[(0.36)(0.64) / 75] = 0.069
To find the critical z value, we look up the z-score that corresponds to a 90% confidence interval in the z-table or calculator.

The z-score is approximately 1.645.

The angle adjacent to the 5 degree angle is 90-5 = 85 degrees

Or you could note that 85+5 = 90.

Then from here you'd use the tangent ratio

tan(angle) = opposite/adjacent

tan(85) = 4629/x

x*tan(85) = 4629

x = 4629/tan(85)

x = 404.985 approximately

296 hot lunches were sold on Friday.

The number of hot lunches sold on Friday can be calculated by multiplying the total number of hot lunches by the relative frequency on Friday:

Hot lunches sold on Friday = 1,350 * 0.22 = 296

Relative frequency is a measure of the number of times an event occurs in a sample, expressed as a proportion of the total number of events. To find the number of hot lunches sold on Friday, we multiply the total number of hot lunches sold in the week by the relative frequency of Friday. This gives us the number of hot lunches sold on Friday, which is 296 in this case. Understanding relative frequency is important in statistics as it helps to summarize data and understand the distribution of events.

The angle PQS is 71 degrees and the angle PQR is 142 degrees.

The line or line segment that divides an angle into two equal pieces is known as the bisector of an angle, also known as the internal angle bisector. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

Given that line, QS is bisecting the angle PQR into two angles RQS and PQ. The angle bisector bisects the two angles into two equal halves.

PQR = RQS

PQS = 71 degrees

PQR = PQR + RQS = 142 degrees
