Answer:

60 minutes

Step-by-step explanation:

Latitude and longitude are measuring lines used for locating places on the surface of the Earth. They are angular measurements, expressed as degrees of a circle. A full circle contains 360°. Each degree can be divided into 60 minutes, and each minute is divided into 60 seconds.

One degree of latitude is equal to approximately 60 nautical miles or 69 statute miles. Since a minute of latitude is one-sixtieth of a degree, it follows that one degree of latitude is equal to 60 minutes.

This means that there are 60 nautical miles or 69 statute miles between two points that differ by one minute of latitude.

The minute of latitude is a widely used unit for measuring distances on Earth, particularly in navigation and aviation. It allows for precise calculations and is crucial for determining positions accurately. Understanding the relationship between degrees of latitude and minutes helps in determining distances, estimating travel times, and ensuring accurate navigation across the globe.

They have the same angle measure because the angles are corresponding angles.

To find the limit of the function g(x) as x approaches 11, we need to evaluate the left-hand limit and the right-hand limit separately and check if they are equal.

Left-hand limit:

lim(x->11-) g(x) = lim(x->11-) (-9) = -9

Right-hand limit:

lim(x->11+) g(x) = lim(x->11+) (7) = 7

Since the left-hand limit and the right-hand limit are different, the limit of g(x) as x approaches 11 does not exist.

Answer:

z=8/5

Step-by-step explanation:

2(4z-1)=3(z+2)

distribute the 2 and 3

8z-2=3z+6

move 2 to the other side by adding 2

8z=3z+8

move 3 to the other side by subtracting 3

5z=8

divide both sides by 5

z= 8/5

The equivalent value of the expression is z = 8/5 = 1.6

Given data ,

Let the equation be represented as A

Now , the value of A is

2 ( 4z - 1 ) = 3 ( z + 2 )

On simplifying the equation , we get

2 ( 4z - 1 ) = 3 ( z + 2 )

So , the left hand side of the equation is equated to the right hand side by the value of 3 ( z + 2 )

Opening the parenthesis on both sides , we get

2 ( 4z ) - 2 = 3z + 6

8z - 2 = 3z + 6

Subtracting 3z on both sides , we get

5z - 2 = 6

Adding 2 on both sides , we get

5z = 8

Divide by 5 on both sides , we get

z = 8/5

z = 1.6

Therefore , the value of z = 8/5 = 1.6

Hence , the expression is z = 8/5 = 1.6

3 is the minimum number of guesses required to guarantee that you know the number.

If we use a binary search approach, we can guess the number in a minimum number of steps.

First, we guess the middle number, which is 8. If the answer is higher, we can eliminate all the numbers from 1 to 8, because they are lower than the answer.

Then we guess the middle number of the remaining numbers, which is 12. If the answer is lower, we can eliminate all the numbers from 12 to 15, because they are higher than the answer.

We have now eliminated half of the remaining numbers, and we are left with 6 and 7. We can guess either of these numbers, and we will know the answer with a total of three guesses.

The probability that a randomly selected person from the survey prefers bacon would be 60% in this example. However, without knowing the specific numbers, we cannot calculate the probability accurately.

To determine the probability that a randomly selected person from the survey prefers bacon, we need additional information such as the total number of respondents in the survey and the number of people who prefer bacon. Without this information, it is not possible to calculate the exact probability.

The probability can be calculated by dividing the number of people who prefer bacon by the total number of respondents in the survey. If the survey provides these specific numbers, we can use the formula:

Probability = Number of people who prefer bacon / Total number of respondents

For example, if the survey includes 100 respondents and 60 of them prefer bacon, the probability would be:

Probability = 60 / 100 = 0.6 or 60%

Therefore, the probability that a randomly selected person from the survey prefers bacon would be 60% in this example. However, without knowing the specific numbers, we cannot calculate the probability accurately.

Answer: x=9

Step-by-step explanation:

2x+10=28

2x=18

x=9

Answer:

9

Step-by-step explanation:

because 2 times 9 is 18 then plus 10 equals 28

Let x be the volume of the 14% HCl solution and y the volume of the 19% HCl solution, in mililiters.

Since the total volume (in mililiters) of the mix should be 330, then:

The total amount of HCl on the first mix is (14/100), on the second mix is (19/100)y and on the final mix, is (17/100)(330). Then:

Isolate x from the first equation and substitute the resulting expression into the second one. Then, solve for y and go back to the first equation with the value of y to find the value of x:

Therefore, 132 ml of 14% HCl solution and 198 ml of 19% HCl solution are needed to create 330 ml of 17% HCl solution.

Step-by-step explanation:

a) Any value outside of Q1 - 1.5(IQR) and Q3 + 1.5(IQR) can be considered a potential outlier.

b) This will give us a visual representation of the distribution of income among the full-time students.

c) It is important to analyze outliers carefully to ensure that they are not artificially skewing the results of our analysis.

(a) To check for outliers in the data set, we can use the box-and-whisker plot or the z-score method. However, since we do not have the exact data, we cannot use these methods. One way to identify potential outliers is to calculate the quartiles (Q1, Q2, and Q3) and the interquartile range (IQR).

(b) To draw a histogram of the data, we can use the frequency distribution table given in the question. The x-axis should represent the income ranges (e.g. $0-$100, $100-$200, etc.) and the y-axis should represent the frequency (i.e. the number of students who earned income within each range).

(c) If there are any outliers in the data set, we need to investigate them further to determine the reason for their unusual values. Possible reasons for outliers could be data entry errors, extreme values due to high- or low-income jobs, or unique situations such as unexpected windfalls or emergencies.

The area under the normal curve to the right of X = 36 is approximately 0.9257.

(a) To compute the z-value corresponding to X = 36, we use the formula:

z = (X - u) / σ

where X is the value of interest, u is the mean, and σ is the standard deviation.

Plugging in the values, we have:

z = (36 - 49) / 9

 = -13 / 9

 ≈ -1.444

Therefore, the z-value corresponding to X = 36 is approximately -1.444.

(b) Given that the area under the standard normal curve to the left of the z-value found in part (a) is 0.0743, we want to find the corresponding area under the normal curve to the left of X = 36.

We can use the z-score to find this area. From part (a), we have z = -1.444. Using a standard normal distribution table or a calculator, we can find the area corresponding to this z-value, which is approximately 0.0743.

Therefore, the area under the normal curve to the left of X = 36 is approximately 0.0743.

(c) To find the area under the normal curve to the right of X = 36, we subtract the area to the left of X = 36 from 1.

Area to the right of X = 36 = 1 - Area to the left of X = 36

                                = 1 - 0.0743

                                = 0.9257

Therefore, the area under the normal curve to the right of X = 36 is approximately 0.9257.

The general solution of the differential equation is: y = c1 e^(3t) cos(t) + c2 e^(3t) sin(t), where c1 and c2 are arbitrary constants determined by the initial or boundary conditions.

The given differential equation is a second-order homogeneous linear differential equation with constant coefficients. Its characteristic equation is obtained by assuming a solution of the form y = e^(rt), where r is a constant. Substituting this into the differential equation, we get:

r^2 e^(rt) - 6r e^(rt) + 10 e^(rt) = 0

Dividing both sides by e^(rt) (which is non-zero), we get:

r^2 - 6r + 10 = 0

Solving for r using the quadratic formula, we get:

r = (6 ± sqrt(6^2 - 4(1)(10))) / 2

r = 3 ± i

Therefore, the general solution of the differential equation is:

y = c1 e^(3t) cos(t) + c2 e^(3t) sin(t)

where c1 and c2 are arbitrary constants determined by the initial or boundary conditions.

This solution consists of a linear combination of two functions: the exponential function e^(3t) and the periodic function cos(t) or sin(t), which oscillates between -1 and 1. The exponential function represents the growth or decay of the system, while the periodic function represents the oscillations or vibrations of the system. The constants c1 and c2 determine the amplitude and phase of the oscillations, respectively. The behavior of the system depends on the signs and magnitudes of the real and imaginary parts of the roots, which determine whether the solutions are overdamped, critically damped, or underdamped.

Answer:

x = -1

y = -7

Step-by-step explanation:

y=9x+2`

-2x+7y=-47  ==> isolate y

Equation 1: 7y = 2x - 47  ==> add 2x on both sides

Equation 2: y = 9x + 2

7 * (y = 9x + 2)

Equation 3: 7y = 63x + 14

Equation 1: 7y = 2x - 47

Subtract equation 1 from equation 3:

  7y = 63x + 14

- (7y = 2x - 47)

7y-7y = 63x-2x + 14-(-47)

0 = 61x + 14 + 47

0 = 61x + 61  ==> solve for x

-61 = 61x  ==> subtract 61 on both sides to isolate x

From the picture attached,

Two lines 'h' and 'k' are the parallel lines and a transversal 'n' is intersecting these parallel lines at two distinct points.

By the theorem of alternate interior angles, angle 8 and angle 11 will be equal in measure.

∠8 ≅ ∠11 [Alternate interior angles]

m(∠8) = m(∠11) = 118°

Therefore, Option (C) will be the answer.

The theorem or postulate that justifies your answer is Alternate Interior Angles Theorem. Option C is correct.

From the given diagram, we are given that m<11 = 118 degrees

To get the measure of angle m<8, we will use the following postulates;

The angle 11 and angle m<12 are supplementary, hence;

m<11 + m<12 = 180

118 + m<12 = 180

m<12 = 180 - 118

m<12 = 62 degrees

The measure of the angle m<11 is also equal to m<8 according to the alternate interior angle theorem. Hence;

m<8 = m<11 = 118 degrees (Alternate Interior Angles Theorem)
