How much money is pictured below?

The volume of a cube is 512 m3.

Given,

The one-face area is nothing but the area of a square since it is a cube.

So,  (a2) = 64 m2.

Then, a = 8m

Hence, the side of the cube is 8 m.

Formula to calculate the volume of the cube :

The volume of the cube = a3

Volume = (8)3

Volume = 512m3

Therefore, the volume of the cube is 512m3.

Answer: 4400

Step-by-step explanation:

The scholarship covers $14,700 / 3 =

14700/3=4900

4900 of Janice's tuition.

After the scholarship, Janice still needs to pay $14,700 - $4900 = 9800 for tuition.

Janice has saved $1000, so she needs to come up with an additional $9800 - $1000 = 8800 for tuition.

Janice and her parents will each pay $8800 / 2 = 4400

Answer:

number from last year - number of decrease

Step-by-step explanation:

The numbers are missing from the problem, but this is what you need to do.

Start with the number of fish in the pond last year.

Subtract the number of decrease.

By solving a little system of equations we will see that the percentage is 66.67%

We know that the regular hourly rate is $30 per hour, and that is the 100% in our case.

So we can write the relation:

$30 = 100%.

We know that when she is on training, she will earn $20, and this is a percentage X that we don't know yet, now we can write the relation:

$20 = X

So we have two equations:

$20 = X

$30 = 100%.

If we take the quotient between these two we will get:

$20/$30 = X/100%

If we multiply both sides by 100% (so we solve the equation for X) we will get:

($20/$30)*100% = X

66.67% = X

So she will get a 66.67% of the regular hourly rate.

The confidence interval approach is the correct method by which to determine sample size. True

Confidence Interval:

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test.

In statistics, confidence is another word for probability. If you create a confidence interval, for instance, with a 95% level of confidence, you can be sure that 95 out of 100 times, the estimate will fall between the upper and lower values indicated by the confidence interval.

Your desired confidence level is usually one minus the alpha (α) value you used in your statistical test:

                    Confidence level = 1 − α

The mid-point of the sides of this quadrilateral are the vertices of a parallelogram.

You should know that in every parallelogram, the opposite sides are equal and parallel.

The given vertices are (2,4), (5,8), (9,5) and (6,1).

Let the vertices be A,B,C,D And the midpoints of the sides be M, N, O, P

Coordinates of A  (2+5)/2 , (4+8)/2 = (3.5 , 6)

Coordinates of B  (5+9)/2 , (8+5)/2 = (7,6.5)

Coordinates of C  (9+6)/2 , (5+1)/2 = (7.5, 3)

Coordinates of D  (6+2)/2 , (1+4)/2 = (4 , 2.5)

The distance between the vertices is denoted by the formula

distance = [tex]\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2} }[/tex]

AB= √(3.5-7)²+(3-6.5)² = √12.5 = 3.5

BC= √(7-7.5)²+(6.5.3)² = √6.5 = 2.5

CD= √(7.5-4)²+(3-2.5)² = √12.5 = 3.5

DA= √(4-3.5)²+(2.5-6)² = √6.5 = 2.5

Answer:

DF=FE

Step-by-step explanation:

first to make it easier we can find the angles to each side

the sum of all angles of a triangle equal 180 degrees so to find x we set all the angles equal to 180

(3x+5)+(4x-15)+(2x+10)=180

9x+0=180

/9.     /9

x=20

now we can find each angle

3(20)+5

60+5

D=65 degrees

4(20)-15

80-15

E= 65 degrees

2(20)+10

40+10

F=50 degrees

Angle D and E are the only angles equal to each other so answer C and d ARE INCORRECT

Since there are 2 of the same angles this is an isosceles triangle

the 2 of the same angles are the base so the side going up are connecting to the top angle F so the sides will be DF and FE and these are equal

What does the math term "probability" mean?

The simple definition of probability is the likelihood that something will occur.

                   We can discuss the probabilities of various outcomes to determine how likely they are whenever we are uncertain about the result of an event. Statistics describes the examination of events subject to probability.

Probability of getting a six on rolling a dice = 1/3

Here ,

n = 4 , p = 1/3

So, For P(X <= 1) = P(X = 0) + P(x = 1)

4C0 * (1/6)^0 * (1 - 1/3)^(4-0) + 4C1 * (1/3)^1 * (1-1/3)^(4-1)

By completing a complete revolution on the soda can-like profile about the y-axis to generates a cylinder-like solid that is the result of the combination of three cones and a cylinder.

In this problem we find a representation of a soda can-like profile, whose complete revolution generates a cylinder-like solid. This solid is the result of the combination of three truncated cones (lower trucated cone, middle cone, upper cone) and a cylinder (right cylinder). There are two axes for the rotation, a horizontal axis (x-axis) and a vertical axis (y-axis).

The first axis, that is, the horizontal axis, is along the base of the can-like profile and the second axis, that is, the vertical axis, is along a side of the can-like profile. The solid of revolution is generated by rotating around the y-axis.
