This cannot be true because -10 is not between 3 and 7. there is no solution to this inequality.

What three steps are involved in resolving an inequality?

Make use of the following steps to solve an inequality:

Step 1: Remove fractions by multiplying all terms by the fractions' lowest common denominator.

Step 2 Combine like terms on both sides of the inequality to simplify.

Step 3 Get the unknown on one side and the integers on the other by adding or subtracting quantities.

ii. To begin, we must use the following set of operations to simplify -7(3+2):

-7(3+2) = -7(5) = -35

The fοci οf the given ellipse are apprοximately (-0.65, 3) and (-3.35, 3).

What is the ellipse?

An ellipse is a clοsed curve in a plane that is symmetric abοut twο intersecting perpendicular axes, called the majοr axis and the minοr axis.

The given equatiοn represents an ellipse centered at the pοint (-2, 3) with semi-majοr axis οf length 4 and semi-minοr axis οf length 3. Tο find the fοci, we can use the fοrmula [tex]\rm c = \sqrt{(a^2 - b^2)[/tex], where a is the length οf the semi-majοr axis and b is the length οf the semi-minοr axis.

In this case, a = 4 and b = 3, so:

[tex]\rm c = \sqrt{(4^2 - 3^2) }= \sqrt7[/tex]

The foci are located on the major axis of the ellipse, which is parallel to the x-axis and passes through the center (-2, 3).

Therefore, the coordinates of the foci are [tex](-2 + \sqrt7, 3)[/tex] and [tex](-2 - \sqrt7, 3)[/tex].

Hence, the foci of the given ellipse are approximately (-0.65, 3) and (-3.35, 3).

Answers

The probability that a worker selected at random makes between $350 and $450 is 68%.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

We can start by standardizing the values of $350 and $450 using the formula:

z = (x - mu) / sigma

where x is the value we want to standardize, mu is the mean, and sigma is the standard deviation.

For $350, we have:

z = (350 - 400) / 50 = -1

For $450, we have:

z = (450 - 400) / 50 = 1

Now, we can use the z-score table or calculator to find the probability of a standard normal distribution between -1 and 1, which is approximately 68%.

Therefore, the probability that a worker selected at random makes between $350 and $450 is 68%.

Find the area of a segment by a chord 8 long in a circle with radius of 8​

Answers

The area of the segment is 5.76 in²

What is a Segment of a Chord?

A segment of a chord refers to a portion of a chord that lies between two points on the circumference of a circle. In other words, a chord is a line segment that connects two points on a circle, and a segment of a chord is any part of that chord that lies between the two endpoints.

For example, if we have a circle with points A and B on its circumference, and a chord that connects these two points, then any portion of the chord that lies between A and B is a segment of the chord.

How to solve

If a chord is 8`` long then α = 60° = π/3 ( the angle between the line segments connecting the ends of the chord and the center of the circle).

A = 1/2 r² ( α - sin α ) = 1/2 · 8² ( π/3 - sin π/3 ) =

90 dL times L/dL equals what

Answers

90 dL times L/dL equals 9 L

How to find 90 dL times L/dL

To understand why 90 dL times L/dL equals 90L, it's important to understand the units involved and how they cancel out.

First, dL stands for deciliter, which is a unit of volume equal to one-tenth of a liter.

L, on the other hand, stands for liter, which is a unit of volume equal to 1000 milliliters or one cubic decimeter.

So, 90 dL represents a volume of 90 deciliters, while L/dL represents a ratio of liters to deciliters.

Specifically, L/dL means "liters per deciliter," which is a way of expressing a conversion factor between liters and deciliters.

Multiplying 90 dL by L/dL involves multiplying 90 dL by the conversion factor of L/dL, which is 1 liter per 10 deciliters. The deciliter units cancel out, leaving only the liter units.

Therefore, we can rewrite the calculation as follows:

90 dL x (1 L/10 dL) = (90/10) L = 9 L

So, the result is 9 L, which is equivalent to 90 dL times L/dL.

Answers

The missing y value for the ordered pair (-25, F2) is F2 = -2343.

What is the ordered pair?

An ordered pair is a pair of numbers that are written in a specific order, typically separated by a comma and enclosed in parentheses.

The first number in the ordered pair represents the x-coordinate, and the second number represents the y-coordinate.

To compute the missing y values for each ordered pair, we need to substitute the given value of C into the equation and solve for F.

For the ordered pair (10, F1), we have C = 10 and F = F1. Substituting these values into the equation, we get:

F1 = 95(10) + 32

F1 = 950 + 32

F1 = 982

Therefore, the missing y value for the ordered pair (10, F1) is F1 = 982.

For the ordered pair (-25, F2), we have C = -25 and F = F2. Substituting these values into the equation, we get:

F2 = 95(-25) + 32

F2 = -2375 + 32

F2 = -2343

Therefore, the missing y value for the ordered pair (-25, F2) is F2 = -2343.

Hence, the missing y values for the ordered pairs

(10, F1) is F1 = 982.

(-25, F2) is F2 = -2343.

Diameter12meters height 2meters what is the volume of the cone in terms of pi

Answers

Answer:

Step-by-step explanation:

It seems like you have provided the dimensions of a cylinder, not a cone. To calculate the volume of a cylinder with a diameter of 12 meters and a height of 2 meters, we can use the formula:

Volume = πr^2h

where r is the radius of the cylinder (half of the diameter). So first, we need to find the radius:

r = d/2 = 12/2 = 6 meters

Now we can plug in the values and calculate the volume:

Volume = π(6 meters)^2(2 meters)

Volume = π(36 square meters)(2 meters)

Volume = 72π cubic meters

Therefore, the volume of the cylinder is 72π cubic meters.

2.375% for 15 years from Discover Home Loans. (You can use Rlab3 for this one i
you feel comfortable enough on your own).

Answers

The answer of the given question is the monthly payment necessary to amortize the loan is $923.98.

What is Principal?

Principal refers to the original amount of money that is borrowed or invested, not including any interest or fees that may accrue over time. In the context of a loan, the principal is the amount that the borrower receives and is responsible for repaying to the lender over a specified period of time, usually with interest.

To calculate the monthly payment necessary to amortize the loan, we can use the following formula:

M = P * (r/12) * (1 + (r/12))ⁿ / ((1 + (r/12))ⁿ - 1)

where:

M = monthly payment

P = principal amount borrowed

r = annual interest rate

n = total number of monthly payments

Plugging in the values for the given loan, we get:

P = 140,000

r = 0.02375 (2.375% expressed as a decimal)

n = 15 years * 12 months/year = 180 months

M = 140,000 * (0.02375/12) * (1 + (0.02375/12))¹⁸⁰ / ((1 + (0.02375/12))¹⁸⁰ - 1)

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

To calculate the monthly payment necessary to amortize a loan, we can use the formula:

P = (A * r) / (1 - (1 + r)^(-n))

Where:

P = Monthly payment

A = Loan amount

r = Monthly interest rate (annual interest rate / 12)

n = Total number of payments (number of years * 12)

Using the formula and plugging in the values from the problem:

A = 140,000

r = 0.02375/12 (2.375% annual interest rate divided by 12 months)

n = 15*12 = 180

P = (140,000 * (0.02375/12)) / (1 - (1 + (0.02375/12))^(-180))

P = $928.52 (rounded to the nearest cent)

What is probability?

Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.

According to the given information:

a) To find the total number of college students surveyed, we can start by adding the number of students who own a tablet, a laptop, or a gaming system:

359 (tablet) + 294 (laptop) + 284 (gaming system) = 937

However, this includes some students who own more than one device. We need to adjust for the overlap:

195 own a tablet and a laptop

200 own a tablet and a gaming system

140 own a laptop and a gaming system

68 own all three devices

To get the total number of unique students who own at least one device, we can subtract the overlap from the initial sum:

937 - (195 + 200 + 140 - 68) = 850

Therefore, 850 college students were surveyed.

b) From the given information, we know that 200 students own a tablet and a gaming system, and 68 own all three devices. Therefore, the number of students who own a tablet and a gaming system, but not a laptop, is:

200 - 68 = 132

Therefore, 132 college students own a tablet and a gaming system, but not a laptop.

c) To find the number of students who own a laptop, but neither a tablet nor a gaming system, we can start by adding the number of students who own a laptop and then subtract the overlap:

294 (laptop) - 195 (tablet and laptop) - 140 (laptop and gaming system) - 68 (all three) = -9

This suggests that there is an error in the data or the calculations, since we cannot have negative students. It is possible that there was a typo or mistake in the original problem.

d) To find the number of students who own exactly two devices, we can add up the number of students who own each pair of devices and subtract the overlap:

195 own a tablet and a laptop

200 own a tablet and a gaming system

140 own a laptop and a gaming system

68 own all three devices

195 + 200 + 140 - 68 = 467

Therefore, 467 college students own exactly two of these devices.

e) To find the number of students who own at least one of these devices, we can simply subtract the number of students who own none of these devices from the total number of students surveyed:

850 - 26 = 824

Therefore, 824 college students surveyed own at least one of these devices.

Therefore,There were 850 college students surveyed. 132 students owned a tablet and a gaming system, but not a laptop. There seems to be an error in the data or the calculations for part c. 467 students owned exactly two of these devices. 824 students owned at least one of these devices.

By evaluating the linear function in different values of x, we will get the complete table:

x         f(x)

-3         -6

-2         -16/3

0            -4

3             -2

6              0

How to complete the table?

Here we have a table of x and f(x) and we want to complete it, to do so, we only need to evaluate the function in different  values of x and then put that in the correspondent places.

if x = -2

f(-2) = (2/3)*-2 - 4

      = -4/3 - 4 = -4/3 - 12/3 = -16/3

if x = 0

f(0) = (2/3)*0 - 4 = -4

if x = 3

f(3) = (2/3)*3 - 4 = 2 - 4 = -2

if x = 6

f(6) = (2/3)*6 - 4 = 0

Then putting these in the table, we will get:

x         f(x)

-3         -6

-2         -16/3

0            -4

3             -2

6              0

What is the ordered pair that is a reflection over the x-axis for the point shown? The x-axis starts at negative 8, with tick marks every one unit up to 8. The y-axis starts at negative 7, with tick marks every one unit up to 7. The point plotted is five units to the left and six units up from the origin. (5, 6) (−5, −6) (6, 5) (−6, −5)

Answers

Answer:

To reflect a point over the x-axis, we need to negate the y-coordinate while keeping the x-coordinate the same.

The given point is located 5 units to the left and 6 units up from the origin. So its coordinates are (-5, 6).

To reflect this point over the x-axis, we negate the y-coordinate to get (−5, −6).

Therefore, the ordered pair that is a reflection over the x-axis for the given point is (−5, −6).

20. An airplane is coming in for a landing. It is currently 80000 feet horizontally away from where it will eventually come to a stop. Its radar indicates that the plane is at an altitude of 60000 feet.

a) At what angle of depression is the plane flying as it lands?

b) In a direct line, how far from its landing destination is the plane?

Please help I will mark you brainless

Answers

Answer:

a.) 36.87 degrees

b.) 100000 feet

Step-by-step explanation:

First, we solve for the direct distance from destination, which is the slope of the triangle. We can use the formula a^2 + b^2 = c^2 for this. Then, by using the trig functions, we can determine the angle of depression by using the inverse of sine of 3/5. This leads to 36.87 degrees.

Answers

By answering the presented question, we may conclude that Therefore, the solutions to the equation 3y² + 5y = 12 are y = -2/3 or y = 1, rounded to the nearest hundredth.

What is equation?

A statement proving the equality of two expressions is known as an equation. It can include variables, integers, and mathematical operations like addition, subtraction, multiplication, and division. It also incorporates mathematical symbols. In mathematics and science, equations are frequently used to illustrate connections between quantities. The equals sign (=) is typically used in equations to denote that the expressions on each side of the sign have the same value. For instance, the formula 2 + 3 = 5 demonstrates that the total of 2 and 3 equals 5. Equations can be solved to determine a variable's value or to determine if a certain value meets the connection that the equation describes.

3y² + 5y = 12

3y² + 5y - 12 = 0

y² + (5/3)y - 4 = 0

y² + (5/3)y + 25/36 - 25/36 - 4 = 0

(y + 5/6)² - 49/36 = 0

(y + 5/6)² = 49/36

y + 5/6 = ±(7/6)

y = (-5 ± 7)/6

y = -2/3 or y = 1

Therefore, the solutions to the equation 3y² + 5y = 12 are y = -2/3 or y = 1, rounded to the nearest hundredth.

Suppose a pharmaceutical company wants to do a study of the commissions of its sales force. Let's assume that there are 4,300 sales people and the population mean for the sales force is $52,400 in commissions and has a population standard deviation of $3,500. What is the probability that a simple random sample of 50 members of the sales force will have commissions within $400 of the population mean?

Answers

Suppose a pharmaceutical company wants to do a study of the commissions of its sales force. the probability that a simple random sample of 50 members of the sales force will have commissions within $400 of the population mean is 0.5812, or 58.12%.

How to find the probability?

We can use the following formula to calculate the standard error of the mean:

Standard error = population standard deviation / sqrt(sample size)

In this case, the standard error is:

Standard error = 3500 / sqrt(50) = 494.9747

Next, we can calculate the z-score for a commission value that is $400 above the population mean as follows:

z = (X - mu) / standard error

where X is the commission value, mu is the population mean, and standard error is the standard error of the mean that we calculated above.

For X = $52,800, the z-score is:

z = (52800 - 52400) / 494.9747 = 0.808

Similarly, we can calculate the z-score for a commission value that is $400 below the population mean:

z = (X - mu) / standard error

For X = $52,000, the z-score is:

z = (52000 - 52400) / 494.9747 = -0.808

Using a standard normal distribution table or calculator, we can find the probability that a random sample of 50 members of the sales force will have commissions within $400 of the population mean:

P(-0.808 < Z < 0.808)

= P(Z < 0.808) - P(Z < -0.808)

= 0.7906 - 0.2094

= 0.5812

Therefore, the probability  is 0.5812, or 58.12%.
