the second one is C. AB/DC = WX/ZY

Probability that [tex]x^2+y^2+z^2\leq 1[/tex] is 0.523

Given that a point (x, y, z) is in space which is randomly selected as

[tex]-1\le x \le 1$,$-1\le y \le 1$,$-1\le z \le 1$[/tex]

These three equations represents a cube in space.

Length of each side of the cube = 1 - -1 = 2

Now  [tex]x^2+y^2+z^2\leq 1[/tex]  represents a sphere with center (0, 0, 0) and of radius less than or equal to 1.

So we can imagine that this sphere is inside the cube.

So the probability that   [tex]x^2+y^2+z^2\leq 1[/tex]  = Volume of the sphere/Volume of the cube

Volume of sphere with radius 1 = [tex]\frac{4}{3} \pi r^3=\frac{4}{3} \pi \times 1 = \frac{4}{3}\times 3.14 = 4.186[/tex] cubic unit

Volume of the cube of length 2 = [tex]2^3 = 8[/tex] cubic units

So the probability that  [tex]x^2+y^2+z^2\leq 1[/tex]  = 4.186/8 = 0.523

Answer:

Length of side 1 = 24 m

Length of side 2 = 120 m

Length of side 3 =  84 m

Step-by-step explanation:

The ratio of each side of triangle is: 2:10:7

Perimeter of triangle = 228 meters

We need to find the length of each side.

Let the common ratio be x

We can write the ratios as: 2x,10x and 7x

Length of side 1 = 2x

Length of side 2 = 10x

Length of side 3 = 7x

Using the formula: [tex]Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle\\[/tex]

Putting values and finding x:

[tex]Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle\\\\228=2x+10x+7x\\19x=228\\x=\frac{228}{19}\\x=12[/tex]

So, we get value of x=12

Now, finding length of each side by putting x=12:

Length of side 1 = 2x =2(12) = 24

Length of side 2 = 10x = 10(12) = 120

Length of side 3 = 7x = 7(12) = 84

So,

Length of side 1 = 24 m

Length of side 2 = 120 m

Length of side 3 =  84 m

Answer:

[tex]\frac{7}{3}-\frac{2}{3}+\sqrt{3}-3\sqrt{3}=\frac{5}{3}-2\sqrt{3}[/tex]    

Step-by-step explanation:

Given the expression

[tex]\frac{7}{3}\:-\:\frac{2}{3}\:+\:v^3\:-\:3v^3[/tex]

solving the expression

[tex]\frac{7}{3}\:-\:\frac{2}{3}\:+\:\sqrt{3}-3\sqrt{3}[/tex]

combine the fractions i.e [tex]\frac{7}{3}-\frac{2}{3}=\frac{5}{3}[/tex]

[tex]\frac{7}{3}\:-\:\frac{2}{3}\:+\:\sqrt{3}-3\sqrt{3}=\frac{5}{3}+\sqrt{3}-3\sqrt{3}[/tex]

add similar elements  i.e [tex]\sqrt{3}-3\sqrt{3}=-2\sqrt{3}[/tex]

                                 [tex]=\frac{5}{3}-2\sqrt{3}[/tex]      

Thus,

Answer:

Tomatoes = 11.5

Onions = 2

Step-by-step explanation:

Andre wants to purchase some onions and tomatoes to make tomato soup. The recipe states that four times the number of tomatoes, , plus five times the number of onions, x, should produce 56 bowls of tomato soup. A different recipe states that two times the number of tomatoes used minus the number of onions used should produce 21 bowls of tomato soup. What is the resulting recipe for the number or tomatoes and onions used in the soup when Andre adds the two recipes together?

Let

Tomatoes = x

Onions = y

Recipe 1:

4x + 5y = 56

Recipe 2:

2x - y = 21

4x + 5y = 56 (1)

2x - y = 21 (2)

Multiply (2) by 5

4x + 5y = 56 (1)

10x - 5y = 105 (3)

Add

10x + 4x = 105 + 56

14x = 161

x = 161 / 14

= 11.5

Substitute x =11.5 into

2x - y = 21

2(11.5) - y = 21

23 - y = 21

-y = 21 - 23

-y = -2

y = 2

Tomatoes = 11.5

Onions = 2

Step-by-step explanation:

Itll only be considered a function when it passed the vertical line test.

The equation y=2x+1 is a linear function

The value of the logarithmic expression log(10³ x) is 3 + log(x).

The opposite of exponential functions is logarithmic functions. The exponential function y = aˣ has the inverse, [tex]x=a^{y}[/tex]. The exponential equation [tex]x=a^{y}[/tex] is defined as being identical to the logarithmic function y = logₐ x.

The properties of logarithm are:

Product rule: logₐ (mn) = logₐ m + logₐ n

Quotient rule: logₐ (m/n) = logₐ m – logₐ n

Power rule: logₐ (mn) = n( logₐ m )

Consider the logarithmic expression,

a = log ( 10³ x )

Using the property of logarithm:

logₐ ( mn ) = logₐ m + logₐ n

Then,

a = log( 10³ x )

a = log( 10³ × x)

a = log( 10³ ) + log( x )

By using the property of logarithm:

logₐ mⁿ = n(  logₐ m )

So,

a = 3( log 10 ) + log( x )

a = 3 + log ( x )

Therefore, log( 10³ x ) = 3 + log ( x ).

Step-by-step explanation:

15 seventh graders play in the jazz band as per the given ratio.

One quantity can be expressed as a fraction of other quantities using a ratio, which is a number. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given At Charles School, 1/5 of the 75 students in seventh-grade play in the jazz band.

In the form of a ratio

1/5 the students out of 75 play in the jazz band

Total students play in the jazz band = 75* 1/5

Total students play in the jazz band = 15

Therefore, The jazz band has 15 seventh graders playing according to the ratio.

The name of the ray shown would be: C. ray AG.

A ray can be defined as a part of a line which has a fixed starting point that is called an endpoint and extends to infinity towards the opposite direction of the fixed point, called the endpoint.

The first letter to use when naming a ray is the letter of the endpoint, which is the starting point of the ray, then use another letter that the ray passes through to infinity.  There would be only one arrow head facing the right, drawn on top of the letters used in naming the ray.

The image shows an endpoint of A, which marks the starting point. The line extends from G to infinity as well.

Therefore, the name of the ray shown would be: C. ray AG.

Step-by-step explanation:

Answer: in each group, there are 8 students.

Step-by-step explanation:

We have a total of 26 students.

If we separate them into 3 equal groups (suppose that each group has X students) and leave 2 students left, we will have the relation:

3*X + 2 = 26

This means that 3 times the number of students in each group, plus the two students leftover must be equal to the initial number of students.

Now we can solve this for X.

3*X + 2 = 26

3*X = 26 - 2 = 24

X = 24/3 = 8

X = 8

This means that in each group there are 8 students.

Step-by-step explanation:

If Tobias borrowed $20,000, and the annual interest rate is 9% of this per year, then we need to find 9% of 20,000.

20,000 x 0.09 = 1,800

Therefore, the yearly interest rate is $1,800. Now, we need to multiply this by 4.

1,800 x 4 = 7,200

Therefore, Tobias repayed a total of $7,200.
