f(x) = 3x - 14I really don’t understand these two question plz help
Answers
Answer:
1) I would remove the '-2' first by adding '2' to both sides. Technically, it does not matter the order you remove the '5' or '-2' though it would be more of a hassle if you were to remove the number associated w/ a variable as you would do extra steps when there is a possibility to do it in less steps. So, ideally, it does matter but depending on your perspective.
2) You would begin by turning '1' into a fraction that has the same denominator as the fraction it is to be added to. This would get you 7/7. Then, you add 7/7 to 4/7 in order to get your final answer of 11/7. You could also just put the two numerical values together as '1 4/7' but I am inferring they want it in an improper fraction format. The steps to get an improper fraction are ideal since it is the simplest way to get to the final answer.

The distribution is symmetric. skewed. both symmetric and skewed.
Answers
The data distribution is skewed to the right. This is because the bars are clustered towards the left side of the histogram and taper off towards the right side.
The histogram of distances students live from school provided in the question shows that the majority of students in Tuan's homeroom live within a short distance of the school, with only a few students living farther away. The distribution is skewed to the right because the bars are clustered towards the left side of the histogram and taper off towards the right side. This indicates that there are fewer students who live farther away from school. A skewed distribution means that the data is not evenly distributed and tends to cluster towards one end. In this case, the distribution is skewed to the right because there are fewer students living farther away from school.

Nora s a race car driver. during a race the first pit stop took 8.352 seconds and the second pit stop took 8.025 seconds. how much faster was the second pit stop
Answers
The second pit stop was 0.327 seconds faster than the first pit stop which is the difference between both time
What is the Subtraction operation?
Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
We have been given that during a race the first pit stop took 8.352 seconds and the second pit stop took 8.025 seconds.
To determine how much faster the second pit stop.
We need to calculate the difference between the first pit stop and the second pit stop of time.
the difference = Time of first pit stop - Time of second pit stop
the difference = 8.352 - 8.025
the difference = 0.327 second

CB is tangent to ⊙A at point C. Find the radius.
Circle A is shown. Line segment A C is a radii. Line segment B C is a tangent and it intersects with the circle at point C. A line is drawn from point B to point A and a point is drawn where the line intersects with the circle. The length of the radius is r, the length of C B is 8, and the length of B to the circle is 5.
Answers
Answer:
The length of the radius is 3.9 units
Step-by-step explanation:
From the details of the circle given, the circle is constructed with MS Visio and attached here;
From the drawing, we have;
The legs of the right triangle ABC = AC and CB
The given length of the leg CB = 8 units
The length from B to the circle on the hypotenuse side = 5 units
The length of the radius, AB = r
By Pythagoras's theorem, we have;
AB² = AB² + CB²
AB = r + 5 By segment addition postulate
Therefore;
(r + 5)² = r² + 8²
∴ (r + 5)² - (r² + 8²) = 0
r² + 10·r + 25 - r² - 8² = 0
10·r - 39 = 0
r = 39/10 = 3.9
The radius, r = 3.9 units long.

Find the equation of the line in slope -intercept form that passes through the following points. Simplify your answer. (-3,-7) and (-12,4)
Answers
The equation of the line in slope-intercept form that passes through the points (-3, -7) and (-12, 4) is y = (11/9)x - (20/3).
To find the equation of the line passing through the given points, we first need to determine the slope of the line. The slope (m) can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
Using the coordinates of the points (-3, -7) and (-12, 4), we substitute the values into the formula:
m = (4 - (-7)) / (-12 - (-3))
m = (4 + 7) / (-12 + 3)
m = 11 / (-9)
m = -11/9
Now that we have the slope, we can use the point-slope form of a line, y - y1 = m(x - x1), to determine the equation. Choosing the point (-3, -7) as (x1, y1), we substitute the values into the equation:
y - (-7) = (-11/9)(x - (-3))
y + 7 = (-11/9)(x + 3)
Next, we simplify the equation:
9(y + 7) = -11(x + 3)
9y + 63 = -11x - 33
9y = -11x - 96
y = (-11/9)x - (96/9)
y = (-11/9)x - (32/3)
Thus, the equation of the line in slope-intercept form that passes through the points (-3, -7) and (-12, 4) is y = (11/9)x - (20/3).

When a wing stalls: O Flow separates from the top and bottom surfaces of the wing O Aircraft wings are designed never to stall O The lift is reduced as the air density over the top surface is less than the lower surface O Flow separates from the top surface of the wing O The lift stops acting upwards and the plane descends
Answers
When a wing stalls, the lift is reduced as the air density over the top surface is less than the lower surface. The flow separates from the top surface of the wing.
The lift stops acting upwards and the plane descends. This is due to the fact that the angle of attack (AOA) is too high and the wing is no longer able to generate enough lift. The wing's airflow separates from the upper surface, causing the wing to lose lift and drag to increase. This condition is known as a stall.
Aircraft wings are designed to avoid stalling, but pilots must be aware of the conditions that can lead to a stall. The wings' AOA is regulated by adjusting the control surfaces, such as flaps, to keep the wing's AOA within a safe range. Pilots are trained to keep their speed high enough to prevent stalling during takeoff and landing.
In conclusion, when a wing stalls, the lift is reduced as the air density over the top surface is less than the lower surface. The flow separates from the top surface of the wing, causing the lift to stop acting upwards and the plane to descend. This is why it is important for pilots to be trained in stall prevention techniques and to avoid situations that can lead to a stall.

Name the geometric terms modeled by a wall and the floor. (Blank 1) Blank 1 options two lines intersecting in a point • two lines intersecting in a line • two planes intersecting in a line three planes intersecting in a point
Answers
Answer: Two planes intersecting in a line
Explanation:
The wall and floor are two different planes. They meet up to form a line which is the crease between them.
A plane is a flat surface without any bends or curves to it. In theoretical terms, planes go on forever in all directions. Realistically there are limits of course. The wall or floor cannot go on forever.
Another example of two planes would be found in a book. Each page is a plane. Two adjacent pages meet up to form a line (i.e. the spine of the book is a line).

At your local store, you are given a coupon for 20% off any store item purchased on Monday. When you return to your store, you notice that an item (normal price = $50) is on clearance for 40% off. You are allowed to use the coupon on the clearance item. How much should you pay for the item? Should it be 60% off of the normal price? Explain why or why not, justify your reason quantitatively.
Answers
The 40% clearance discount is already factored into the clearance price of $30, so applying the 20% coupon only reduces the price further by 20% of $30, or $6. Therefore, you would pay $24 for the item with both discounts applied.
Let's break down the discounts and calculate the final price of the item using the terms "normal", "price", and "quantitatively".
The normal price of the item: $50
First, apply the 40% clearance discount:
40% off the normal price = 0.4 * $50 = $20
Subtract the clearance discount from the normal price:
New discounted price = $50 - $20 = $30
Now, apply the 20% off coupon to the discounted price:
20% off the new discounted price = 0.2 * $30 = $6
Quantitatively, the calculation would be:
Normal price = $50
Clearance price (40% off) = $30
Coupon discount (20% off clearance price) = 0.20 x $30 = $6
Final price = $30 - $6 = $24
Subtract the coupon discount from the discounted price:
Final price = $30 - $6 = $24
So, you should pay $24 for the item. It is not the same as taking 60% off the normal price because the discounts are applied sequentially, not combined. Quantitatively, you can see that taking 60% off the normal price would result in a $30 discount ($50 * 0.6), while the actual total discount here is $26 ($20 + $6).
