Determine whether the following pair of equations having parallel or perpendicular lines or not: 4x - 6y = 12 and 6x + 4y = 12 AN

Answers

Answer 1

The pair of equations, 4x - 6y = 12 and 6x + 4y = 12, represents a pair of perpendicular lines.

To determine if two lines are parallel, we compare the slopes of the lines. The slope-intercept form of a line is y = mx + b, where m represents the slope.

Let's rewrite the equations in slope-intercept form:

Equation 1: 4x - 6y = 12

Rearranging the equation, we have:

-6y = -4x + 12

Dividing by -6, we get:

y = (2/3)x - 2

Equation 2: 6x + 4y = 12

Rearranging the equation, we have:

4y = -6x + 12

Dividing by 4, we get:

y = (-3/2)x + 3

Comparing the coefficients of x, we see that the slopes of both lines are (2/3) and (-3/2). Since the slopes are not equal, the lines are not parallel. Instead, they are perpendicular to each other.

The diameter of a semicircle is 10 meters. What is the perimeter of the semicircle, in meters? Round your answer to the nearest tenth.

Answers

Answer:

25.7 m

Step-by-step explanation:

The formula for the circumference of a circle is C = 2(pi)(r), where r is the radius, which in turn is half the diameter.  Thus, the formula for the circumference is C = (d)(pi).  The perimeter of a semicircle is half that, or

C = (pi)(r), which here is (3.14)(5 m) = 15.7 m.  Finally, the total perimeter is the sum of this 15.7 m and the 10 m diameter of the circle:

P = 15.7 m + 10 m = 25.7 m

Suppose there are 8 boys and 7 girls in a classroom. If one student is chosen at random to run a errand. What is the probability that the student will be a girl?

Answers

Answer:

47%

Step-by-step explanation:

There are 15 total students, so find the percentage of girls out of the total students: 7/15= .466, which is about 47%. To double check, you can do the boys and make sure it adds to 100%. 8/15= .533, which is about 53%. 47+53=100. So girls are 47% and boys are 53%

Would you consider data on grades (of a particular class)
collected over two semesters to be cross-sectional or times series
data and why?

Answers

The data on grades (of a particular class) collected over two semesters would be considered as time series data.

Time series data refers to any set of data collected over time, where time acts as a variable in the data set. Time series data consists of repeated measurements of the same variable taken over regular intervals of time.

A time series is a collection of observations obtained by observing a single variable or a single data point over a certain period of time. Time series data are ordered sequentially and collected at evenly spaced intervals of time. In this question, the grades were collected over two semesters, which are considered a series of two data points that were collected over time. Hence, it is a time series data.

Decide whether the composite functions, fog and gof, are equal to x. f(x) = * 1,5 g(x) = 2x - 5 - +5 2 O No, no O Yes, yes O Yes, no O No, yes.

Answers

No, neither fog nor gof is equal to x. The expressions fog(x) = 2/5x - 1 and gof(x) = 2/5x - 5 have different constant terms, indicating that they are not equal to x. The correct option is O (No, no.)

To determine whether the composite functions, fog and gof, are equal to x, we need to evaluate them using the functions f(x) = 1/5x and g(x) = 2x - 5.

First, let's calculate fog:

fog(x) = f(g(x)) = f(2x - 5) = 1/5(2x - 5) = 2/5x - 1

Next, let's calculate gof:

gof(x) = g(f(x)) = g(1/5x) = 2(1/5x) - 5 = 2/5x - 5

Comparing fog and gof, we can see that they are not equal to x. Specifically, fog(x) = 2/5x - 1 and gof(x) = 2/5x - 5.

Therefore, the correct option is "No, no" as neither fog nor gof is equal to x.

Alternatively, if we simplify fog and gof as a single expression, we have fog(x) = 2/5x - 1 and gof(x) = 2/5x - 5. Since both expressions have different constant terms, they cannot be equal to x.

CNNBC recently reported that the mean annual cost of auto insurance is 958 dollars. Assume the standard deviation is 144 dollars, and that the population is normally distributed. You will use a simple random sample of 99 auto insurance policies. Note: You should carefully round any intermediate values you calculate to 4 decimal places to match wamap's approach and calculations. Find the probability that a single randomly selected policy has a mean value between 934.8 and 965.2 dollars. P(934.8 < X < 965.2) = Enter your answer as a number accurate to 4 decimal places

Answers

Probability that a single randomly selected policy has a mean value between $934.8 and $965.2 is approximately 0.5819.

To find probability we can use the properties of the normal distribution.

Given,

Mean (μ) = $958

Standard deviation (σ) = $144

Sample size (n) = 99

We want to find the probability P(934.8 < X < 965.2).  X represents the mean value of a randomly selected policy.

Calculate z-score for the lower value.

z1 = (934.8 - μ) / (σ / sqrt(n))

Calculate z-score for the upper value.

z2 = (965.2 - μ) / (σ / sqrt(n))

Cumulative probability between the z-scores.

P(934.8 < X < 965.2) = P(z1 < Z < z2)

If P(Z < z1) = 0.2658. P(Z < z2) = 0.8477. The probability of interest would be.

P(934.8 < X < 965.2) = P(z1 < Z < z2) = P(Z < z2) - P(Z < z1) = 0.8477 - 0.2658 = 0.5819

Probability that a single randomly selected policy has a mean value between $934.8 and $965.2 is approximately 0.5819.
