Answer:

855764 won

Step-by-step explanation:

Given that:

Total budget = 2,192,896

Mexpsena

Extended travel pass = 85,210

Plane tickets = 725,726

Food = 203,396

Hostel room = 322,800

Given the expenses highlighted above,

Amount left :

Total budget - Expenditure

2,192,896 won - (85,210 + 725,726 + 203,396 + 322,800) won

(2,192,896 - 1337132) won

= 855764 won

Answer:

got it right on test

Answer: y=-x+7

Step-by-step explanation:

Answer:

Your given points: (9,-2)and (1,6)

x1=9

y1=-2

x2=1

y2=6

Step-by-step explanation:

To find slope take the points you got from graph and put it into the equation y2-y1/x2-x1

6-(-2)/1-9=6+2/1-9=8/-8=-1

SLOPE IS m=-1

Then take that slope u got and plug into this equation to find equation of the line

y-y1=m(x-x1)

y-(-2)=-1(x-9)

y+2=-x+9

-2. -2

Answer:

greater risk of a Type I error and a lower risk of a Type II error

Step-by-step explanation:

Remember, in statistics, alpha (or the significance level) α,  refers to the probability of rejecting the null hypothesis when it is true.

Hence, setting alpha at 0.05 (or 5%) instead of 0.01 (or 1%) implies that the researcher is increasing how far away the statistics data needs to be from the null hypothesis value before they can decide to reject the null hypothesis. In other words, a probability of 5% is greater than 1%, resulting in a greater risk of a Type I error and a lower risk of a Type II error.

Answer:

The value is  [tex]P( X > 80 ) = 0.58901[/tex]

Step-by-step explanation:

From the question we are told that

    The sample size is  n  =  24

    The mean is  [tex]\mu = 82[/tex]  

    The standard deviation is  [tex]\sigma = 8.9[/tex]

Generally the  probability that a randomly chosen student earned a B or higher on the test (score of 80 or higher )  is mathematically represented as

         [tex]P( X > 80 ) = P( \frac{ X - \mu }{\sigma } > \frac{ 80 - 82 }{ 8.9 } )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

 =>  [tex]P( X > 80 ) = P(Z > -0.225 )[/tex]

From the z table  the area under the normal curve to the right  corresponding to    -0.225  is  

     [tex]P(Z > -0.225 ) = 0.58901[/tex]

=>   [tex]P( X > 80 ) = 0.58901[/tex]

Answer:

The value of the sample proportion for the given sample is 0.7

Step-by-step explanation:

Given;

total number of students selected (sample) = 50

number of students that responded they do not read the textbook = 35

The value of the sample proportion for students that do not read their statistics textbook in the given sample is calculated as;

sample proportion = 35 / 50

sample proportion = 0.7

Therefore, the value of the sample proportion for the given sample is 0.7

Answer:

y - 6 = -8(x - 6)

Step-by-step explanation:

point-slope form is y-y₁=m(x-x₁)

we have slope=-8 and also this point (6,6) so

y - 6 = -8(x - 6)

Answer:

dy/dt = 1.02 m/s

Step-by-step explanation:

First of all, let the distance of the dock above the bow of the boat be represented by x.

Also, let the distance of the boat from the dock be represented by y.

Let z represent the length of the rope.

Now, we can use pythagoras theorem to find a relationship between x, y and z since they form a right angle triangle where the vertical part is the dock, the base represents the water and the hypotenuse represents the rope.

Thus;

x² + y² = z²

Using implicit differentiation, we have;

2x(dx/dt) + 2y(dy/dt) = 2z(dz/dt)

We are given that the dock is 1 meter above the bow. Thus, x = 1

Also, the height is not changing and so dx/dt = 0

We are told the dock is 5 feet away from the boat. Thus, y = 5

dy/dt is is the speed we are looking for which is the rate at which the boat is approaching the dock.

We are not given the value of z but we can find it by using pythagoras theorem since we know the dock is 1 meter above the bow and the boat is 5 m away.

Thus;

z = √(1² + 5²)

z = √26

We are told the rope is being pulled in at the rate of 1 m/s. Thus; dz/dt = 1

Plugging all relevant values into the differentiation equation above gives;

2(1)(0) + 2(5)(dy/dt) = 2(√26)(1)

10(dy/dt) = 2√26

Divide both sides by 10 to get:

dy/dt = (√26)/5

dy/dt = 1.02 m/s

Answer:

The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

Step-by-step explanation:

By definition of rectangular prism, we get the respective formulas for the volumes of the community swimming pool and the wadling pool, respectively:

Community swimming pool

[tex]V_{c} = l\cdot w\cdot h[/tex] (1)

Wading pool

[tex]V_{w} = \left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w[/tex] (2)

Where:

[tex]l[/tex] - Length of the swimming pool, measured in feet.

[tex]h[/tex] - Depth of the swimming pool, measured in feet.

[tex]w[/tex] - Width of the swimming pool, measured in feet.

[tex]V_{c}[/tex] - Volume of the community swimming pool, measured in cubic feet.

[tex]V_{w}[/tex] - Volume of the wading swimming pool, measured in cubic feet.

The ratio of the volume of the community swimming pool to the volume of the wadling pool is:

[tex]\frac{V_{c}}{V_{w}} = \frac{l\cdot w \cdot h}{\left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w}[/tex] (3)

[tex]\frac{V_{c}}{V_{w}} = \frac{1}{\frac{1}{4} }[/tex]

[tex]\frac{V_{c}}{V_{w}} = 4[/tex]

The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

Answer:

$321.30

Step-by-step explanation:

Area = Length x width.

Area of room = 15 x 24 = 360 square feet.

Now multiply the square feet by the cost:

360 x 5 = $1800

It will cost $1,800

Answer:

9

Step-by-step explanation:

If the mark up is 75% then the price of a necklace is 56.7

the least they want to profit is 500

so the answer should be at least 9, because the price is over 55, which would be 550 if multiplied by 10

Answer:

51.3333

Step-by-step explanation:

Multiply your speed in miles per hour by 5,280. This is the number of feet in a mile. The result is your speed in feet per hour. For example, 60 miles per hour times 5,280 feet per mile is 316,800 feet per hour.

Answer:

$118.706 or rounded to $118.71

Step-by-step explanation:

Since it is on sale, find the discount price. $139 * 0.8 = 111.20

I used 0.8 because you got 20% off so it is only 80% of original price or 0.8 of original price.

Then 111.20 * (1.0675) = $118.706 or rounded to $118.71.

Tax is 6.75% or 0.0675. It is on top of the discount price, so use 1.0675.

Alternatively you can find 0.0675 * 111.20 and add that to 111.20 and still get the same answer.
