A water station table at a marathon starts with 200 plastic cups on it. Every minute, 15 cups are taken from the table. How many minutes could have passed if there are fewer than 65 cups on the table?

Step-by-step explanation:

To simplify the expression -6(4v - x - 5), we distribute the -6 to each term inside the parentheses:

-6(4v - x - 5) = -6(4v) - (-6x) - (-6)(5)

Simplifying each term:

-6(4v) = -24v

-(-6x) = 6x

-(-6)(5) = 30

Therefore,

-6(4v - x - 5) = -24v + 6x - 30

So the simplified expression is -24v + 6x - 30.

Answer: (-3,-2)

Step-by-step explanation:

 The image of the point (2,−3) under a clockwise rotation of 90° (R_90) about the origin can be found by swapping the x and y-coordinates and changing the sign of the new x-coordinate.

So, the new x-coordinate will be -3 and the new y-coordinate will be -2.

Therefore, the image of the point (2,−3) under a clockwise rotation of 90° (R_90) about the origin is (-3,-2).

Answer:

Step-by-step explanation:

Let's call the weight of Karen's package "w" in pounds.

For the first courier, the cost is given by:

Cost = 20 + 2w

For the second courier, the cost is given by:

Cost = 12 + 3w

We know that these costs are equivalent, so we can set them equal to each other:

20 + 2w = 12 + 3w

Simplifying this equation, we get:

8 = w

So the weight of Karen's package is 8 pounds.

To find the cost, we can plug this weight into either of the equations above:

For the first courier:

Cost = 20 + 2(8) = 36

For the second courier:

Cost = 12 + 3(8) = 36

So it will cost Karen $36 to deliver her package, and the weight of the package is 8 pounds.

[tex]a^{2}[/tex] + [tex]7^{2}[/tex] = [tex]10^{2}[/tex]

[tex]a^{2}[/tex] + 49 = 100  Subtract 49 from both sides

[tex]a^{2}[/tex] + 49 - 49 = 100 - 49

[tex]a^{2}[/tex] = 51

Helping in the name of Jesus.

Answer: 14.28 cm

Step-by-step explanation:

So, 10 squared = 7 squared + X squared.

This can be simplified to: 100 = 49 + X squared.

Then, you subtract 49, and are left with 51 = X squared

Then, take the square root if 51, you get approx. 7.14 cm.
since this is an equilateral triangle, the answer will be the same for the second half of the base.
So, 7.14 x 2, 14.28 cm

the measurement of the fourth angle of the quadrilateral is 95 degrees.

To find the measurement of the fourth angle of a quadrilateral when the measures of three angles are given, we can use the fact that the sum of the measures of the angles in a quadrilateral is 360 degrees.

Let's denote the measure of the fourth angle as x. Then we can write an equation:

80 + 120 + 65 + x = 360

Simplifying this equation, we get:

x = 360 - 80 - 120 - 65 = 95

Therefore, the measurement of the fourth angle of the quadrilateral is 95 degrees.

Finding the limit of the function limx→0 ((sin( 1- cos4x))/(1 - cos4x)) = 1

The limit of a function is the value which the function tends to as the dependent variable tends to a particular value.

Since we require the limit limx→0 ((sin(1-cos4x))/(1-cos4x))

So, substituting x = 0 into the equation, we have

limx→0 ((sin(1-cos4x))/(1-cos4x)) = ((sin(1-cos4(0)))/(1-cos4(0)))

=  ((sin(1 - cos(0)))/(1 - cos(0)))

=  ((sin(1 - 1))/(1 - 1))

= sin0/0

= 0/0

Since we have an indeterminate form, we use L'hopital's rule which states that if limx→0 f(x) = limx→0 g(x) = 0,

Then limx→0 f(x)/g(x) = limx→0 f'(x)/g'(x)

So, limx→0 ((sin( 1- cos4x))/(1 - cos4x)) = limx→0 d((sin(1-cos4x))/dx/d(1-cos4x))/dx

Let 1 - cos4x = u and 4x = v

1 - cosv = u

=  limx→0 d((sin(1 - cos4x))/dx/d(1 - cos4x))/dx

=  limx→0 d((sinu)/dx/du/dx

=  limx→0 d((sinu)/du × du/dv × dv/dx ×/du/dv × dv/dx

Now du/dv = sinv and dv/dx = 4 and d

So,

limx→0 d((sinu)/du × du/dv × dv/dx ×/du/dv × dv/dx =  limx→0 d((sinu)/du × sinv × 4 ×/sinv × 4

=  limx→0 cosu × sinv × 4 ×/sinv × 4

=  limx→0 cos(1 - cos4x) × sin4x × 4 ×/sin4x × 4

= cos(1 - cos4(0)) × sin4(0) × 4 /sin(4(0) × 4

= cos(1 - cos0) × sin(0) × 4 /sin(0) × 4

= cos(1 - 1) × 0 × 4 /0 × 4

= cos(0) × 0 × 4 /0 × 4

=  1 × 0 × 4 /0 × 4

= 0/0

Since   limx→0 f'(x)/g(x) = 0/0, we differentiate again.

So

limx→0 cos(1 - cos4x) × sin4x × 4 /sin4x × 4  =  limx→0 dcos(1 - cos4x) × sin4x × 4/dx/dsin4x × 4/dx

Let 1 - cos4x = u and 4x = v

1 - cosv = u

limx→0 [d((cosu)/du × du/dv × dv/dx × sinv + cosu dsinv/dv × dv/dx]/du/dv × dv/dx =  limx→0 d((sinu)/du × sinv × 4 ×/sinv × 4

=  limx→0 -sinu × sinv × sinv × 4 + 16cosvcosu /cosv × 4 × 4

=  limx→0 [-4sin(1 - cos4x) × sin²4x + 16cos4xcos(1 - cos4x)]/16cos4x

=  [-4sin(1 - cos4(0)) × sin²4(0) + 16cos4(0)cos(1 - cos4(0))]/16cos4(0)

=  [-4sin(1 - cos(0)) × sin²(0) + 16cos(0)cos(1 - cos(0))]/16cos(0)

=  [-4sin(1 - 1)) × (0) + 16(1)cos(1 - 1)]/16cos(0)

=  [-4sin(0)) × (0) + 16(1)cos(0)]/4cos(0)

=  [-4(0) × (0) + 16(1)(1)]/16(1)

= (0 + 16)/16

= 16/16

Answer:

First, we need to standardize the values using the formula:

z = (x - mu) / sigma

where x is the value, mu is the mean, and sigma is the standard deviation.

For $450: z = (450 - 400) / 50 = 1

For $550: z = (550 - 400) / 50 = 3

Using the 68-95-99.7 rule, we know that approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.

Since we are interested in the probability of a worker making between $450 and $550, we need to find the area under the normal curve between z = 1 and z = 3.

Using a standard normal table or calculator, we can find that the area under the curve between z = 1 and z = 3 is approximately 0.1359.

Therefore, the probability that a worker selected at random makes between $450 and $550 is 13.59% (rounded to two decimal places).

1. Data is approx bell-shaped and symmetric

2. Median is between 150 to 175

A histogram is a graphical representation of a frequency distribution of a set of continuous data. It is used to display the shape of the data and to show how frequently certain values occur within a given range or interval.

In a histogram, the x-axis represents the range or interval of the data, and the y-axis represents the frequency of occurrence of values within each interval.

The data is divided into a set of bins or intervals, and the height of each bar on the histogram represents the number of data points that fall within that particular bin. The bars of the histogram are typically drawn adjacent to each other, with no gaps between them, to emphasize the continuity of the data.

Therefore, from the histogram used to represent the given data, it can be seen that the data is symmetric and also the median has the values between 150 to 175

Given the function

f(x) = 5x√(x + 1)

Factor out 5

So, we have

f(x) = 5[x√(x + 1)]

The derivative is then calculated using the following chain rule

f'(x) = 5[du/dx * dy/du]

When differentiated, we have

f'(x) = 5[√(x + 1) + x/2[√(x + 1)]]

This gives

f'(x) = 5[3x + 2/2[√(x + 1)]]

So, we have

f'(x) = [15x + 10]/[2√(x + 1)]

Substitute -2/3 for x

f'(-2/3) = [15(-2/3) + 10]/[2√((-2/3) + 1)]

The equation that can be solved to predict the number of times Harris will spin a sum less than 10 is B) 12/500 = x/15

Harris should expect to spin a sum of 10 or greater 240 times.

It should be noted that to predict the number of times Harris will spin a sum less than 10, we need to find the probability of getting a sum less than 10 and multiply it by the total number of experiments (500).

The possible sums that can be obtained are: 5, 6, 7, 8, 9, 10, 11, and 12. The probability of getting a sum less than 10 is the sum of the probabilities of getting each of these outcomes, which is:

P(sum less than 10) = P(1 and 4, 1 and 5, 2 and 4, 2 and 5, 3 and 4, 3 and 5)

= 6/15 * 2/5

= 4/25

Multiplying this probability by the total number of experiments (500), we get:

Number of times Harris will spin a sum less than 10 = (4/25) * 500 = 80

Therefore, the correct equation to predict the number of times Harris will spin a sum less than 10 is: 12/500 = x/15

Part B: Based on the information, the possible outcomes that give a sum of 10 or greater are: 10, 11, and 12. The probability of getting a sum of 10 or greater is the sum of the probabilities of getting each of these outcomes, which is:

P(sum of 10 or greater) = P(1 and 9, 2 and 8, 3 and 7, 4 and 6, 5 and 5, 6 and 4, 7 and 3, 8 and 2, 9 and 1, 8 and 3, 7 and 4, 6 and 5)

= 12/15 * 3/5

= 36/75

= 12/25

Multiplying this probability by the total number of experiments (500), we get:

Number of times Harris should expect to spin a sum of 10 or greater = (12/25) * 500 = 240

Therefore, Harris should expect to spin a sum of 10 or greater 240 times.

Answer: the slower bus travels at 55 miles per hour and the faster bus travels at 73 miles per hour.

Step-by-step explanation:

768 = 6x + 6(x + 18)

Simplifying this equation, we can distribute the 6 on the right-hand side:

768 = 6x + 6x + 108

Combining like terms, we get:

768 = 12x + 108

Subtracting 108 from both sides:

660 = 12x

Dividing both sides by 12:

x = 55

So the slower bus is traveling at 55 miles per hour. To find the speed of the faster bus, we can add 18:

x + 18 = 55 + 18 = 73

Answer: one is 55 and the other is 73

Step-by-step explanation:

lets say x is for the slower bus. for every hour the become x+x+18

In light of this, the cylinder's total surface area falls between approximately 1017.9 cm²and 1357.2 cm².

A cylinder's total surface area is equal to the sum of all of its faces' surface areas. The cylinder's total surface area—the sum of its curved and circular areas—has a radius of "r" and a height of "h." The entire surface area of the cylinder is calculated as follows:

Total Surface Area of Cylinder = 2r (h + r) square units.

The three-dimensional shape of a cylinder is made up of two parallel circular bases connected by a curved surface. It is seen as a prism since its base is a circular. It is frequently used as a container and can either be solid or hollow 13.

The following formula can be used to get a cylinder's total surface area:

A = 2πr² + 2πrh

where r is the cylinder's base's radius, h is the cylinder's height, and is a mathematical constant roughly equal to 3.14159.

Yet, we can locate a variety of potential surface areas using the provided information. With the assumption that the radius is equal to the feedback's half (9 cm), we can
