Step-by-step explanation:
Two students created a list of steps for the following construction. Which student has steps in the correct order, and which does not? Explain.
The steps of student B are in the correct order but the steps of student A are in the incorrect order.
What is a perpendicular and parallel line?Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines and the lines that never intersect are known as parallel lines.
We have:
You are given AB and point C. Construct a line parallel to AB that passes through point C
The correct way to draw a parallel line to AB that passes through point C is:
1. Draw a line that intersects points B and C.2. Place the compass on point B, and swing an arc that crosses line AB and line BC. Label the points D and E.3. Keep the compass at the same width, and place it on point C.4. Swing an arc that crosses line BC, and label the point F.5. Open the compass to the width between points D and E.6. Keeping the compass at the same width, place it on point F.7. Swing an arc that intersects the arc created from line BC at point C.8. Mark the intersection of the two arcs as point G.9. Draw a line through point C and point G.The steps of student B are in the correct order but the steps of student A are in the incorrect order.
Thus, the steps of student B are in the correct order but the steps of student A are in the incorrect order.

Which compound inequality is equivalent to the absolute value inequality |bl> 6?
-6> b and b> 6
b>-6 or b < 6
-6 6
b<-6 or b> 6
Answer:
b > -6 or b < 6
Step-by-step explanation:
The absolute value operator always returns a positive number, with |b| = b if b > 0, and |b| = -b if b 0. With this in mind, consider the following inequality:
|b| > 6Because of the absolute value operator, this is valid for b values larger than 6 and less than -6. As a result, the compound inequality that this circumstance illustrates is:
b< -6 or b > 6The compound inequality is equivalent to the absolute value inequality |bl> 6 is b < -6 or b > 6.
Option D is the correct answer.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
The absolute value inequality |b| > 6 is equivalent to the compound inequality b < -6 or b > 6.
To see why, consider that the absolute value of b is greater than 6 if b is either greater than 6 or less than -6 (because the absolute value of any number greater than 6 or less than -6 will be greater than 6).
So, we can write the inequality as:
|b| > 6
b > 6 or -b > 6
b > 6 or b < -6
b < -6 or b > 6 (rearranging the terms)
Therefore,
The compound inequality is equivalent to the absolute value inequality |bl> 6 is b < -6 or b > 6.

A manufacturer of four-speed clutches for automobiles claims that the clutch will not fail until after 50,000 miles. A random sample of 10 clutches has a mean of 58,750 miles with a standard deviation of 3775 miles. Assume that the population distribution is normal. Does the sample data suggest that the true mean mileage to failure is more than 50,000 miles. Test at the 5% level of significance.What kind of hypothesis test is this?A. One Proportion z-TestB. One mean t-testC. Two Proportions z-TestD. Two mean t-testE. Paired Data
The sample data suggests that the true mean mileage to failure is more than 50,000 miles with a 5% level of significance. This is a one mean t-test.
In this question, we are testing a hypothesis about a population mean based on a sample of data. The null hypothesis is that the population mean mileage to failure is equal to 50,000 miles, while the alternative hypothesis is that it is greater than 50,000 miles. Since the sample size is small (n = 10), we use a t-test to test the hypothesis. We calculate the t-value using the formula t = (sample mean - hypothesized mean) / (standard error), and compare it to the t-critical value at the 5% level of significance with 9 degrees of freedom. If the calculated t-value is greater than the t-critical value, we reject the null hypothesis and conclude that the true mean mileage to failure is more than 50,000 miles.

what is Evaluate 4/5-3/7
Answer:
\( \frac{13}{35} \)
Step-by-step explanation:
To add or subtract two or more fractions from each other, the denominators have to be the same. To make the denominators the same, we should find the least common multiple of 5 and 7. The least common multiple of 5 and 7 is 35. 5 should be multiplied with 7 to get 35 and 7 should be multiplied with 5 to get 35 (with both numerators).
\( \frac{4}{5 } - \frac{3}{7} \)
\( \frac{4 \times 7}{5 \times 7} - \frac{3 \times 5}{7 \times 5} \)
\( \frac{28}{35} - \frac{15}{35} \)
\( \frac{13 }{35} \)
When subtracting, only subtract the numerators (the denominators are kept as is).

The function C(t) = 25. 50t - 16. 75 represents the cost of buying a certain number of tickets to the concert with a $16. 75 coupon. The cost, C, is measured in dollars for t tickets
The given function, C(t) = 25.50t - 16.75, represents the cost, C, in dollars for buying a certain number of tickets, t, to the concert. To understand this function, let's break it down step by step:
The first term, 25.50t, represents the cost of each ticket without the coupon. This means that for every ticket, the cost is $25.50.
The second term, -16.75, represents the discount you get by using the $16.75 coupon. Since this term is subtracted, it reduces the overall cost by $16.75.
Combining both terms, we get the overall cost of buying t tickets after applying the coupon.
For example, if you want to find the cost of buying 5 tickets, you can substitute t = 5 into the function:
C(5) = 25.50(5) - 16.75
= 127.50 - 16.75
= 110.75
So, the cost of buying 5 tickets after applying the coupon would be $110.75.
The given function C(t) = 25.50t - 16.75 represents the cost, C, in dollars for buying a certain number of tickets, t, to the concert after applying a $16.75 coupon. You can substitute a value for t into the function to find the corresponding cost.

Suppose the average yearly salary of an individual whose final degree is a master's is $47 thousand less than twice that of an individual whose final degree is a bachelor's. Combined, two people with each of these educational attainments earn $112 thousand. Find the average yearly salary of an individual with each of these final degrees.
Answer:
m= masters degree salary and b=bachelors degree salary.
m = 2b - 45000
m + b = 112000
Substitute to get
2b - 45000 + b = 112000
3b = 156000
b = 52000
So m = 59000
Check to see if these numbers work
59000 = 2*52000 - 45000 true
59000 + 52000 = 112000 true
Step-by-step explanation:
The average yearly salary of an individual with each of these final degrees is $53000 and $59000
What are average?The average can be calculated by dividing the sum of observations by the number of observations.
Average = Sum of observations/the number of observations
Given;
The final degree is a master's is $47 thousand less than twice that of an individual whose final degree
Now let, Average salary of a bachelor's degree = b
Salary of a master's holder = 2b - 47000
Combined salary of both degrees will be;
b + (2b - 47000) = 112000
b + 2b - 47000 = 112000
3b = 112000 + 47000
3b = 159000
b = 53000
Therefore, the Average salary of a bachelor's degree and master's degree will be $53,000 and 2(53000) - 47000 = 59,000.
