Answer:

D: Left side

Step-by-step explanation:

Step-by-step explanation:

The coefficient of C in the inequality 56C+64R<9000 represents the rate of fuel consumption while flying through clear skies. From the inequality, we can see that the rate of fuel consumption while flying through clear skies is 56 gallons per minute.

To find the initial fuel capacity of the airplane, we need to set the values of C and R to zero in the inequality 56C+64R<9000, since this represents the scenario where the plane flies entirely through clear skies and does not encounter any rain clouds.

56(0) + 64(0) < 9000

Simplifying the inequality, we get:

0 < 9000

This means that the inequality is true for any positive value of C and R, including C = 0 and R = 0. Therefore, the airplane has more than 0 gallons of fuel before takeoff, but the exact amount is not specified in the given information.

The given inequality is:

56C + 64R < 9000

We know that the airplane consumes fuel at a constant rate while flying through clear skies. Let the fuel consumption rate be F (in gallons per minute) and let the amount of fuel the airplane has before takeoff be T (in gallons).

We need to find the values of F and T that satisfy the given inequality.

First, we can simplify the inequality by dividing both sides by 8:

7C + 8R < 1125

Next, we can use the fact that the airplane consumes fuel at a rate of 64 gallons per minute while flying through rain clouds to write an expression for the total fuel consumption during R minutes:

64R

Similarly, the total fuel consumption during C minutes while flying through clear skies is:

FC

The total fuel consumption during both C and R minutes can be expressed as:

FC + 64R

We know that the total fuel consumption must be less than the initial amount of fuel, which is T. Therefore, we can write:

FC + 64R < T

Substituting FC = F * C, we get:

F * C + 64R < T

We can rearrange this inequality to solve for T:

T > F * C + 64R

Now we can use the inequality 7C + 8R < 1125 to solve for F and T.

Let's assume the airplane has enough fuel to fly for 1 hour (60 minutes) in clear skies and no rain clouds. Then C = 60 and R = 0. Substituting these values into the inequality, we get:

56(60) + 64(0) < 9000

3360 < 9000

This is true, so our assumption is valid.

Using the assumption that the airplane has enough fuel to fly for 1 hour in clear skies, we can solve for F and T:

T > F * C + 64R

T > F * 60 + 64(0)

T > 60F

Since we assumed the airplane has enough fuel to fly for 1 hour in clear skies, T must be greater than the amount of fuel consumed during that time:

T > F * 60

Combining these two inequalities, we get:

60F < T < 60F + 3360

Now we can choose any value of F between 0 and 64 that satisfies the inequality, and choose a value of T that is greater than 3360 + 60F. For example, we can choose:

F = 30 (assuming a fuel consumption rate of 30 gallons per minute in clear skies)

T = 4000 gallons (initial amount of fuel)

Substituting these values into the inequality, we get:

56C + 64R < 9000

56(60) + 64R < 9000

3360 + 64R < 9000

64R < 5640

R < 88.125

Therefore, the airplane can fly for 88.125 minutes (or approximately 1 hour and 28 minutes) through rain clouds before consuming all of its fuel, if it is flying at a rate of 64 gallons per minute. And if the airplane consumes fuel at a rate of 30 gallons per minute while flying through clear skies, it has 4000 gallons of fuel before takeoff

The measure of angle K is 47.2° ( nearest tenth)

The Cosine Rule says that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.

From the rule;

c² = a²+b²+2abcosC

to find K we must find angle J

22² = 15²+15²+ 2× 15 × 15cos J

484 = 225+225+ 450cosJ

484 = 450+450cos J

450cos C = 484-450

450cos C = 34

cos J = 34/450

cos J = 0.075

J = cos^-1( 0.075)

J = 85.7°

The sum of angle in a triangle is 180°

x+x + 85.7 = 180

2x = 180-85.7

2x = 94.3

x = 94.3/2 = 47.2(nearest tenth)

To complete her journey Ann needs to run for (120/3) = 40 minutes in order to travel at an average speed of 5 km/h.

We can start by using the formula:

average speed = total distance ÷ total time

Let's first calculate the total distance Ann covers:

distance walked = speed x time = 4 km/h x (8 km / 4 km/h) = 8 km

distance run = speed x time

Let's call the time Ann runs for "t". Then:

distance run = 8 km/h x (t/60) h = (8t/60) km

Total distance = distance walked + distance run = 8 km + (8t/60) km = (480 + 8t) / 60 km

Now, let's find the total time:

total time = time walked + time run

time walked = distance ÷ speed = 8 km ÷ 4 km/h = 2 h

time run = t/60 h

total time = 2 h + t/60 h = (120 + t)/60 h

Now we can substitute the values we have found into the formula for average speed:

5 km/h = [(480 + 8t)/60 km] ÷ [(120 + t)/60 h]

Simplifying the right-hand side, we get:

5 km/h = (480 + 8t) / (120 + t)

Multiplying both sides by (120 + t), we get:

600 + 5t = 480 + 8t

Subtracting 480 and 5t from both sides, we get:

120 = 3t

Therefore, Ann has to run for (120/3) = 40 minutes to have an average speed of 5 km/h over her complete journey.

According to given information, Joanna bought 6 notebooks and 8 pencils with total cost $20.94, which is answer choice A.

What is cost?

cost refers to the amount of money required to purchase or produce a particular item or service.

Let's assume that Joanna bought x notebooks and y pencils. We know that she bought a total of 14 items, so:

x + y = 14

We also know that the total cost of her purchase was $20.94, so:

2.05x + 1.08y = 20.94

We can use the first equation to solve for x:

x + y = 14

x = 14 - y

Substitute this expression for x in the second equation:

2.05x + 1.08y = 20.94

2.05(14 - y) + 1.08y = 20.94

28.7 - 2.05y + 1.08y = 20.94

-0.97y = -7.76

y = 8

Substitute this value of y back into the equation x + y = 14:

x + 8 = 14

x = 6

The answer is option b. confidence coefficient.

To explain this, let's start by defining interval estimation. Interval estimation is a statistical method used to estimate an unknown population parameter (such as the population mean or proportion) by constructing a range of values, called a confidence interval, that contains the true value of the parameter with a certain level of confidence.

The level of confidence refers to the percentage of times that the interval estimation procedure will generate an interval that contains the actual value of the population parameter being estimated. For example, a 95% confidence level means that if we were to repeat the interval estimation procedure many times, we can expect to obtain a confidence interval that contains the true population parameter 95% of the time.

The confidence coefficient, on the other hand, is the probability that a particular confidence interval actually contains the true value of the population parameter. It is the complement of the significance level, which is the probability of making a Type I error (rejecting a true null hypothesis). For example, if we have a 95% confidence level, then the confidence coefficient is 0.95, and the significance level is 0.05.

Therefore, the confidence coefficient represents the probability that the interval estimation procedure will generate an interval that contains the actual value of the population parameter being estimated. It is a measure of how confident we are that the estimated interval contains the true population parameter.

In conclusion, the confidence coefficient is a crucial concept in interval estimation that reflects the probability of obtaining a confidence interval that includes the true population parameter. It provides a measure of the reliability and accuracy of the interval estimation procedure and helps researchers interpret the results of their analyses.

Answer:

First, we can calculate the discount from the sale. The sweater costs $65.99, and with a 40% discount, the price is reduced by:

$65.99 x 0.40 = $26.40

So the sale price of the sweater is:

$65.99 - $26.40 = $39.59

Next, we can apply Carson's $10 coupon to the sale price:

$39.59 - $10 = $29.59

Therefore, Carson pays $29.59 for the sweater after the discounts.

To calculate the total discount that Carson receives, we can first find the amount of the 40% discount on the sweater, which is:

40% of $65.99 = 0.4 x $65.99 = $26.40

Then, we can add the additional $10 coupon discount to get the total discount:

$26.40 + $10 = $36.40

Therefore, the total discount that Carson receives on the sweater is $36.40.

To find the final price that Carson pays after the discounts, we can subtract the total discount from the original price:

$65.99 - $36.40 = $29.59

Therefore, Carson pays $29.59 for the sweater after the discounts.

Let's start by using the formula for the total labor cost:

Total labor cost = Fixed cost + (Number of employees x Cost per employee)

We know that the fixed cost is $32,782.00, and the cost per employee is $31,009.00. Let's represent the number of employees with the variable "x". So we have:

$3,133,682.00 = $32,782.00 + (x * $31,009.00)

Simplifying the equation:

$3,133,682.00 - $32,782.00 = x * $31,009.00

$3,100,900.00 = x * $31,009.00

x = $3,100,900.00 / $31,009.00

x ≈ 100

Therefore, the company intends to employ approximately 100 people next year.

First, we need to find the volume of one brick by multiplying its three dimensions:

Volume of one brick = 7.25 in x 21.25 in x 3.25 in = 526.0156 cubic inches

Next, we can find the weight of one brick by multiplying its volume by its weight per cubic inch:

Weight of one brick = 526.0156 cubic inches x 0.06 ounces/cubic inch = 31.56094 ounces

The total weight of 1800 bricks can be found by multiplying the weight of one brick by 1800:

Total weight of 1800 bricks = 31.56094 ounces/brick x 1800 bricks = 56,809.6928 ounces

Finally, we can find the cost of the bricks by multiplying their total weight by the cost per ounce:

Decreasing the circumference of a tire by 20% would increase the number of rotations required to travel a given distance.

What is Circumference ?

Circumference is the distance around the outside of a circle or a curved object. It is the measurement of the boundary line or the perimeter of the circular object. The circumference of a circle is calculated using the formula C = 2πr, where "C" is the circumference, "r" is the radius of the circle, and "π" (pi) is a mathematical constant approximately equal to 3.14159.

The number of rotations of a tire depends on its circumference, which is the distance around the outside of the tire. If the circumference of a tire decreased by 20%, it means that the distance around the outside of the tire would be 20% less than it was before. This would cause the tire to cover less ground in each rotation, which would result in an increase in the number of rotations needed to travel a given distance. Specifically, the number of rotations would increase by 20% for the same distance traveled, as the tire would need to rotate more times to cover the same distance due to the reduced circumference.

Therefore, decreasing the circumference of a tire by 20% would increase the number of rotations required to travel a given distance.

The length 53.1°, 90°, and 39.9°,vertical length: 3/5 ,length of vertical: 4/5 1 hypotenuse.

Angle is a geometric concept that describes the relative difference between two straight lines or planes that meet at a common point. It is measured in degrees, radians or grads, and is often represented by the symbol θ. An angle can be acute, right, obtuse, straight, reflex, or full. Angles can be used to measure the size of a triangle, to calculate the area of a figure, and to determine the position of a point in a coordinate system.

We possess that

Angle = 53.1°

Vertical length = 3/5 (this is the adjacent cathetus)

Vertical length equals 4/5 (this is the opposite cathetus)

We can use it to check this.

tg(angle) = adjacent/opposite:

tg(53.1) = 1.33

and

(4/5)/(3/5) = 4/3 = 1.33

This makes sense, then.

Using the relationship, we can now identify the hypotenuse:

Sin(angle) = the antipode or hypotenuse

sin(53.1) = (4/5)/H

H = (4/5)/sin(53.1) = 1

Hence, there is always a 90° angle in a triangle or rectangle.

We may get the final angle using the fact that the sum of a triangle rectangle's three interior angles is always 180 degrees.

A + 53.1° + 90° = 180°

A = 90° - 53.1° = 36.9°

bucket has 2 objects. The 85 is required number of students to that atleast one Year and 21 students in same year and same major.

The required number of elements in set A and set B as per given elements of A, B , and A ∪ B is equal to |A ∩ B| = 3.

Number of elements in set A,  |A| = 97

Number of elements in set B, |B|  = 16

Total number of elements in set A or set B,  |A ∪ B| = 110

Use the formula for the size of the union of two sets,

|A ∪ B| = |A| + |B| - |A ∩ B|

where |A| represents the number of elements in set A,

|B| represents the number of elements in set B,

And |A ∩ B| represents the number of elements in the intersection of sets A and B.

Rearrange the formula to solve for |A ∩ B|,

|A ∩ B| = |A| + |B| - |A ∪ B|

⇒|A ∩ B| = 97 + 16 - 110

⇒|A ∩ B| = 3

Therefore, the number of elements in sets A and B have 3 elements in common.
