    [tex]P=2+4+2+1+4+5=18cm[/tex]

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:

2,500,000

Step-by-step explanation:

To write 2.5 million, you can write it as 2,500,000. This is because one million is equal to 1,000,000. So, 2.5 million is equal to 2,500,000.

Answer:

2500000 <--- in numbers

Two million and five hundred thousand OR Two and a half million

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).

Step-by-step explanation:

The predicted likelihood that Nestor will win at least six of the upcoming races is therefore 90.1%, which is closest to the correct response of -1%.

The likelihood or chance that a specific occurrence or outcome will occur is quantified by probability. It is represented by a number between 0 and 1, with 0 denoting an impossibility and 1 denoting a certainty. For instance, there are two equally likely outcomes (heads or tails), but only one of them is heads, hence the probability of flipping a fair coin and obtaining heads is 0.5 or 50%. By dividing the number of favorable outcomes by the total number of possible outcomes, one can calculate probability.

given

We can see that Nestor won a medal in 6 out of the 10 trials by counting the number of victories.

We can use the binomial distribution with parameters n=10 (number of trials) and p=0.79 to calculate the likelihood that this will occur (probability of success).

The following calculation can be used to determine the likelihood of at least 6 successes in 10 trials:

P(X>=6) = 1 - P(X<=5)

Using a calculator for the binomial distribution, we obtain:

P(X>=6) = 90.1%

The predicted likelihood that Nestor will win at least six of the upcoming races is therefore 90.1%, which is closest to the correct response of -1%.

Apprοximately 31 mοving bοxes οn the flοοr οf the stοrage unit, given the dimensiοns οf the bοxes and the aisle.

In mathematics and geοmetry, dimensiοns refer tο the number οf cοοrdinates needed tο specify the lοcatiοn οf a pοint οr οbject in space.

Tο calculate the number οf mοving bοxes that can fit οn the flοοr οf the stοrage unit, we need tο first calculate the usable flοοr space by subtracting the width οf the aisle frοm the tοtal width οf the stοrage unit.

The usable floor space can be calculated as follows:

Usable floor space = 10 ft - 3 ft (aisle) = 7 ft

Next, we need to calculate how many boxes can fit in a row along the length and width of the usable floor space.

Along the length of the floor space, we can fit:

Number of boxes along length = 10 ft / 18 in = 20/3 boxes

Similarly, along the width of the floor space, we can fit:

Number of boxes along width = 7 ft / 18 in = 14/3 boxes

Since we can only stack the boxes one layer high, the total number of boxes that can fit on the floor of the storage unit can be calculated by multiplying the number of boxes along the length by the number of boxes along the width:

Total number of boxes = (20/3) x (14/3) = 280/9 ≈ 31

Therefore, we can fit approximately 31 moving boxes on the floor of the storage unit, given the dimensions of the boxes and the aisle.

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

The radius of the circle is 36 centimeters.

A circle's circumference may be divided up into its arcs. Two endpoints and the curve connecting them serve as its definition. The size of the central angle that subtends an arc determines its length. The formula L = r, where L is the length of the arc, r is the radius of the circle, and is the measurement of the central angle in radians, yields the length of an arc in radians. Arcs of circles are utilised in geometry and trigonometry as well as in many other contexts, including creating circular objects and calculating angles.

The length of an arc of a circle is given by the formula:

L = rθ

Given, length of the arc is 32π centimeters and central angle = 8/9π.

Substituting the value we have:

32π = r(8/9π)

r = (32π)/(8/9π)

r = 36

A function can be represented by a formula or a graph. The method y = 2x + 1 is an example of a conceptual model in which each value assigned to x yields a value of y.

Both Glass A and Glass B initially hold the same amount of liquid. Assume that the total amount of liquid that each glass can hold is equal to 6 units.

As a result, Glass A is initially filled with 3 units of liquid (1/2 of 6 units) and Glass B is initially filled with 2 units of liquid (1/3 of 6 units).

When the liquid from Glass B is poured into Glass A, the total amount of liquid in Glass A increases to 5 units (3 units + 2 units), and the glass is now completely filled.

Because BF and CE bisect each other at point D, we know that angles BDC and EDC are congruent, and angles BDF and CDE are also congruent, as they are vertical angles.

In mathematics, an angle is a geometric figure formed by two rays or line segments that share a common endpoint called the vertex. The rays or line segments are called the sides of the angle.

Angles are typically measured in degrees or radians, and they are denoted using the symbol ∠. The measure of an angle is the amount of rotation needed to bring one side of the angle into coincidence with the other. A full rotation is 360 degrees or 2π radians.

Angles can be classified into different types based on their measures and their relationships with other angles. Some common types of angles include:

Acute Angle: An angle whose measure is less than 90 degrees.

Right Angle: An angle whose measure is exactly 90 degrees.

Obtuse Angle: An angle whose measure is greater than 90 degrees but less than 180 degrees.

Because BF and CE bisect each other at point D, we know that angles BDC and EDC are congruent, and angles BDF and CDE are also congruent, as they are vertical angles.

By definition of angle bisectors, we know that CD=DE and BD=DF.

Thus, the triangle congruence principle SAS (side-angle-side) allows us to deduce that Triangle BCD is congruent to Triangle ECD, since they share side CD, angle BDC and angle EDC.

Therefore, BC=CE (corresponding sides of congruent triangles are equal) and CE=EF (because CE bisects segment BF).

Thus, BC=EF, and we have proven that BC is equal to EF

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

Step-by-step explanation:

distance = rate x time

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

and this is happening for 6 hours so its is 6(2x+18)=768

x=55

x+18=73
