The owner of a computer repair shop has determined that their daily revenue has mean​ $7200 and standard deviation​ $1200. The daily revenue totals for the next 30 days will be monitored. What is the probability that the mean daily revenue for the next 30 days will exceed​ $7000? Round to four decimal places.

Answer:

Step-by-step explanation:

This translates immediately into n/7 = 9.  We can isolate (find) n by multiplying both sides of this equation by 7, obtaining n = 63.

Or we could guess and check:  if the quotient is 9, we could round that up to 10, obtaining n/7 = 10, or n = approximately 70.

Answer:

Sample Answer: Quotient means the result of division. To use guess and check to solve, you would divide different numbers by 7 until you get 9. The result is 63 ÷ 7 = 9. The quotient of sixty-three and seven is nine.

Step-by-step explanation:

My Answer: Guess and check means you guess different numbers until you get the correct answer. For example, let’s start with the number 60. You will get a decimal if you do that problem, so that’s no the answer. Then you keep guessing. The correct answer is 63. 63 divided by 7 is 9.

Answer:

13 sq cm.

Step-by-step explanation:

To find the area of this irregular figure, we will need to find the areas of a rectangle and triangle within this figure.

To find the area of the rectangle, we can simply do:

1 × 4= 4  sq cm.

Now, this is where it gets a little trickier. To find the area of the triangle, we will first need to determine the base and height.

We can see from the diagram that to find the base, we need to subtract:

7-4= 3 cm. This is the base of ONLY the triangle.

To find the height, we will need to do:

5+1= 6 cm. This is the total height of the entirety of the triangle.

We can now use the Triangle Area formula: [tex]\frac{1}{2}[/tex](bh), to calculate the area of the triangle.

[tex]\frac{1}{2}[/tex] (6*3)= 9 sq cm.

Finally, add the areas of the rectangle and triangle together, giving you:

9+4= 13 sq cm.

Answer: A. 724

Step-by-step explanation:

Answer:

height = 6 cm

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius and h the height )

Here V = 100.48 and r = 4, thus

[tex]\frac{1}{3}[/tex]π × 4²h = 100.48

Multiply both sides by 3 to clear the fraction

3.14 × 16h = 301.44 ( divide both sides by 3.14 × 16 )

h = [tex]\frac{301,44}{3.14(16)}[/tex] = 6 cm

Answer: 821.9 cube meters

Step-by-step explanation:

Hi, to answer this question we have to calculate both rectangular prisms volume:

Volume: Length x width x height

Replacing with the values given:

Large solid volume = 12.4 x 7.8 x9 =870.48 cubic meters

Small solid volume = 3 x 1.8 x 9 =48.6 cubic meters

Next, we have to subtract the smaller solid's volume to the large solid’s volume .

870.48-48.6 = 821.88 = 821.9 cubic meters

At the time that it is kicked, the ball is on the ground, that is, it's height is 0 feet.

Step-by-step explanation:

The height of the ball after t seconds is given by the following equation:

[tex]h(t) = -2t^{2} + 10t[/tex]

What is the height of the ball at the time it is kicked?

The ball is kicked at t = 0.

So we have to find h(0)

[tex]h(0) = -2*0^{2} + 10*0 = 0[/tex]

At the time that it is kicked, the ball is on the ground, that is, it's height is 0 feet.

Please consider the graph.

We have been given that graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.  We are asked to choose the weights, which are within 2 standard deviations of the mean.

We can see from our graph that mean of the weights is 9.5 and standard deviation in 0.5.

The data point that would be below two standard deviation is: [tex]9.5-2\times 0.5[/tex] that is [tex]9.5-1=8.5[/tex].

The data point that would be above two standard deviation is: [tex]9.5+2\times 0.5[/tex] that is [tex]9.5+1=10.5[/tex].

Now we need to check the data points that lie within 8.5 and 10.5.

Upon looking at our given choices, we can see that 8.9, 9.5 and 10.4 pounds lie within 2 standard deviation of the mean.

Therefore, 8.9 lbs, 9.5 lbs and 10.4 lbs are correct choices.

Answer:

a) 59.87%

Step-by-step explanation:

Given that the mean temperature (μ) = 23.5°C and the standard deviation (σ) is 2 °C.

The z score is used in statistics to measure number of standard deviation by which the raw score is above or below the mean value, It is calculated using the equation:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

The average temperature of the City of Van Nuys is 23 degrees. The z score is

[tex]z=\frac{x-\mu}{\sigma}=\frac{23-23,5}{2} =-0.25[/tex]

P(x > 23) = P(z > -0.25) = 1 - P(z < -0.25) = 1 - 0.4013 = 0.5987 = 59.87%

Step-by-step explanation:

The distance formula can be used for this.

  d = √((x2 -x1)² +(y2 -y1)²) = √((12 -0)² +(1 -10)²) = √(144 +81) = √225

  d = 15

_____

Alternate solution

You may recognize that the slope of the line is -3/4, suggesting that this is some multiple of a 3-4-5 right triangle. That multiple is 9/3 = 12/4 = 3, so the hypotenuse of the triangle is 5×3 = 15 units.

Final answer:

The distance between the points (0,10) and (12,1) is 15 units.

Explanation:

The distance between the points (0,10) and (12,1) can be found using the distance formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Substituting the given coordinates, the calculation becomes:

d = sqrt((12 - 0)^2 + (1 - 10)^2)

d = sqrt(12^2 + (-9)^2)

d = sqrt(144 + 81)

d = sqrt(225)

d = 15

Therefore, the distance between the two points is 15 units.

Answer:

Final answer:

The volume of the larger cylinder is 36 cm².

Explanation:

To find the volume of the larger cylinder, we need to compare the surface areas of the two cylinders. Let's assume that the surface area and volume of the smaller cylinder are represented by SA1 and V1 respectively, and the surface area and volume of the larger cylinder are represented by SA2 and V2 respectively.

Since the cylinders are similar, their surface areas and volumes are proportional. Therefore, we can set up the following ratio: SA1 / SA2 = V1 / V2. Plugging in the given values, we get: 24 / 54 = 16 / V2. Solving for V2, we find that the volume of the larger cylinder is 36 cm².

-12x2 + 6x

12x - 6

Option A and E are the correct answer

The only expression equivalent to 12x - 6 is 6(2x-1). Hence first option is correct.

The question asks which expressions are equivalent to 12x - 6. Let's evaluate each given option:

6(2x-1): Distributing the 6 gives 12x - 6, which is equivalent to the original expression.

-6(2x+1): Distributing the -6 gives -12x - 6, which is not equivalent to the original expression.

-6(2x-1): Distributing the -6 gives -12x + 6, which is not equivalent to the original expression.

-6x(2x-1): This expression cannot be simplified to the form of a single term in x and a constant; thus, it's not equivalent.

6x(2-1): Simplifying inside the parentheses first gives 6x, which is not equivalent to the original expression.

Therefore, the only expression equivalent to 12x - 6 is 6(2x-1).

Answer:

7.1 lbs / ft^3

Step-by-step explanation:

In this question, we are asked to calculate the density of the sphere in the diagram.

Firstly, to calculate the density , we apply a mathematical formula.

Mathematically, density = mass/volume

We have the mass already from the question but we will need to calculate what the volume is.

Mathematically, the volume of a sphere = 4/3 * pi * r^3

From the diagram, we can see that the radius of the sphere is 3 ft. Plugging this into the equation of the volume of a sphere, we have;

4/3 * 22/7 * 3^3

= 4/3 * 22/7 * 27

= 113.143 ft^3

Now, we substitute the volume into the density equation;

Recall, density = mass/volume

From the question, our mass is 800 lbs and from calculations, volume is 113.143 ft^3

Density = 800 lbs/ 113.143 ft^3 = 7.07 lbs/ ft^3 which is approximately 7.1 lbs/ ft^3

Answer: P(landing on orange)=1 - [2/3 + 1/12 + 1/12]

so =1/6

The probability of landing on orange is 1/6.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.

The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Probability Formula = f/n

where,

f is the number of times an event occurs

n is the total number of trials

It is given that

The probability of landing on red is 2/3, on green 1/12, on blue is 1/12.

The probability of happening a event is P , then Probability of not happening is 1-P

the probability of landing on orange

= 1- { (2/3) +(1/12)+(1/12)}

=1/6

Therefore the probability of landing on orange is 1/6.
