Answer: 980 tickets

Step-by-step explanation:

A band sold out a concert that has 4,200 seats. A random sample of 120 ticket buyers was surveyed, and 28 buyers were found to have made their purchase on the first day the tickets were being sold. This means (28/120) = 7/30 of the 120 ticket were purchased on the first day.

To get the number of first day tickets purchased when 4,200 tickets are likely to have been purchased will be the fraction gotten multiplied by 4200. This will be:

= 7/30 × 4200

= 29400/30

= 980 tickets

Answer: x > 5

Step-by-step explanation: To solve for x in this inequality, your goal is the same as it would be if you were solving an equation, to get x by itself on one side.

Since 8 is being subtracted from x, add

8 to both sides of the inequality.

On the left the -8 +8 cancels out

and on the right, -3 + 8 is 5.

So we have x > 5.

Question 1: The hours that will pass between two consecutive times, when the water is at its maximum height is π hours

Question 2: Sin of the angle is -0.8

Step-by-step explanation:

Question 1: Here we have h(t) = 4·cos(t) + 10

The maximum water level can be found by differentiating h(t) and equating the result to zero as follows;

[tex]\frac{\mathrm{d} h(t)}{\mathrm{d} t} = \frac{\mathrm{d} \left (4cos(t) + 10 \right )}{\mathrm{d} t} = 0[/tex]

[tex]\frac{\mathrm{d} h(t)}{\mathrm{d} t} = - 4 \times sin(t) = 0[/tex]

∴ sin(t) = 0

t = 0, π, 2π

Therefore, the hours that will pass between two consecutive times, when the water is at its maximum height = π hours.

Question 2:

B = (3, -4)

Equation of circle = x² + y² = 25

Here we have

Distance moved along x coordinate = 3

Distance moved along y coordinate = -4

Therefore, we have;

[tex]Tan \theta = \frac{Distance \ moved \ along \ y \ coordinate}{Distance \ moved \ along \ x \ coordinate} = \frac{-4}{3}[/tex]

[tex]\therefore \theta = Tan^{-1}(\frac{-4}{3}) = -53.13^{\circ}[/tex]

Sinθ = sin(-53.13) = -0.799≈ -0.8.

Answer:

75

Step-by-step explanation:

Given:

mAB =105

The minor arc given mAB is 105. Subtract that from 360 to get the measure of the major arc mACB

<=> mACB = 360 - 105 = 255

As we know, the measure of an angle formed by two tangents intersesting outside the circle can be found by one haft of the difference between the mearsure of two intercepted arcs

=> the measure of ∠P is:

= (mACB - mAB)/ 2

= (255 - 105)/2

= 75

Answer:

The ocean influences weather and climate by storing solar radiation, distributing heat and moisture around the globe, and driving weather systems.

One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.

Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.

The ocean impacts Earth's four major systems in several ways. Here are some examples:

Geosphere: The ocean is closely connected to the geosphere, as it plays a significant role in shaping the Earth's surface. Waves and currents erode coastlines and move sediment around, while underwater volcanic activity can create new landmasses and alter ocean chemistry.

Atmosphere: The ocean is an important component of the Earth's climate system, with ocean currents and temperatures influencing weather patterns and regulating the Earth's temperature. The ocean also absorbs carbon dioxide from the atmosphere, which helps to mitigate the effects of climate change.

Biosphere: The ocean supports a vast array of life, from microscopic plankton to massive whales. Marine ecosystems are interconnected with terrestrial ecosystems, with many species relying on the ocean for food and habitat.

Hydrosphere: The ocean is the largest component of the Earth's hydrosphere, and plays a critical role in the water cycle. Ocean currents and evaporation drive the movement of water around the planet, while the ocean stores vast amounts of water that can be released into the atmosphere through evaporation.

As for how the ocean keeps west coast cities cool during the summer, this is due to a phenomenon called coastal upwelling. As warm air rises over the land, it creates a low-pressure zone that draws in cool, moist air from the ocean.

This cool air can then be pushed inland by the sea breeze, providing relief from the summer heat. Additionally, the cold water that is brought to the surface during upwelling helps to cool the air near the coast.

the approximate percentage of light bulb replacement requests numbering between 40 and 47 is 34% .

Step-by-step explanation:

Step 1: Sketch the curve.

The probability that 40<X<47 is equal to the blue area under the curve.

Step 2:

Since μ=40 and σ=7 we have:

P ( 40<X<47 ) = P ( 40−40 < X−μ < 47−40 )=P ( 40−40/7< X−μ/σ < 47−40/7)

Since Z = x−μ/σ , 40−40/7 = 0 and 47−40/7 = 1 we have:

P ( 40<X<47 )=P ( 0<Z<1 )

Step 3: Use the standard normal table to conclude that:

P ( 0<Z<1 )=0.3413

Percentage = 0.3413(100)=34.13%

Therefore , the approximate percentage of light bulb replacement requests numbering between 40 and 47 is 34% .

Answer:

The equation x = y-8

The equation  (y-8) y = 240

The first number x = 12 and second number y =20

Step-by-step explanation:

Explanation:-

Step(l):-

Let 'x' be the first number and 'y' be the second number

Given the product of two numbers is 240

Given  data        x y = 240 …(l)

Given data the first number is 8 less than the second number.

                       x = y-8...(ll)

Substitute (ll) in equation (l) , we get

                           (y-8) y = 240

                           [tex]y^{2} -8y -240 =0[/tex]

                            [tex]y^{2} -20y+12y -240 =0[/tex]

                           [tex]y(y -20)+12(y -20) =0[/tex]

                           [tex](y +12)(y -20) =0[/tex]

                          y = -12 and y = 20

              Y= -12 is not satisfied

              we can choose y = 20

Step(ll):-

Given data x =y-8

  substitute value y = 20 in x = y -8

                                             x = 20-8 = 12

Final answer:-

The first number x = 12 and second number y =20

Final answer:

To calculate the total cost of two pairs of shoes priced at $19.99 each with a buy one get one 20% off deal, first find the discount amount for the second pair, then add this discounted price to the full price of the first pair, resulting in a total of $35.98.

Explanation:

The question asks how much you will pay in total if you buy two pairs of shoes priced at $19.99 each, with a sale of buy one get one 20% off.

First, calculate the discount on the second pair. 20% of $19.99 is $3.998, which rounds to $4.00 when applying standard mathematical rounding.

Therefore, the second pair of shoes would cost $19.99 - $4.00 = $15.99. Now, add the price of the first pair of shoes to the discounted price of the second pair to get the total: $19.99 + $15.99 = $35.98.

Answer:

7 cups of soda

Step-by-step explanation:

If we call the number of cups you buy by "x", we have that the price for the refillable cup P1 is:

P1 = 6 + 0.79*x

And the price for the other option is:

P2 = 1.69*x

To find how many sodas do you need to buy to make it work buying the refillable cup, you just need to equate the two prices and find the value of x:

P1 = P2

6 + 0.79*x = 1.69*x

0.9*x = 6

x = 6/0.9 = 6.6667 cups

So, you need to buy at least 7 cups of soda to make the refillable cup worth it.

Answer:

x^6-9 = x^-3 = 1/x^2

Step-by-step explanation:

Hi! I'm happy to help!

To solve this, we need to simplify this expression as much as possible. We see that in the exponent, we have the expression 6-9, which we can substitute for -3.

[tex]x^{6-9}[/tex]

[tex]x^{-3}[/tex]

To further simplify, we need to find out what [tex]x^{-3}[/tex] is. Whenever using a negative exponent, follow this equation.

[tex]x^{-y}[/tex]=[tex]\frac{1}{x^{y} }[/tex]

Using this, we can turn [tex]x^{-3}[/tex], into [tex]\frac{1}{x^{3}}[/tex]. Since we do no know what x is, we cannot simplify any further.

To sum it up, [tex]\frac{1}{x^{3}}[/tex] is an equivalent expression for [tex]x^{6-9}[/tex].

Answer:

The correct answer is 9 m per [tex]second^{2}[/tex]

Step-by-step explanation:

Force is defined by mass of an object times it's acceleration.

Let the mass of the object be m kilograms.

When a force of 30 N acts on a certain object the acceleration of the object is 5 m per [tex]second^{2}[/tex]

∴ 30 = m × 5

⇒ m = 6.

If the force is changed to 54 N, let the acceleration of the object be x  m per [tex]second^{2}[/tex].

∴ 54 = m × x

⇒ x = [tex]\frac{54}{6}[/tex] = 9

Thus when the force is 54 N, the acceleration of the object is 9 m per [tex]second^{2}[/tex].
