Two fair dice are rolled 4 times and the sum of the numbers that come up are recorded. Find the probability of these events. A) the sun is 5 on each of the four rolls. B) the sun is 5 exactly three times in the four rolls.

Answer:

x = 2

y = 0

Step-by-step explanation:

We can solve using substitution, substitute y in the first equation with the second equation:

-(-6x + 12) + 3x = 6

Distribute the negative sign:

6x - 12 + 3x = 6

Combine like terms:

9x - 12 = 6

Isolate the variable and solve for x by adding 12 in both sides:

9x = 18

x = 2

Substitute 2 with x in any equation to find the value of y:

-y + 3(2) = 6

-y + 6 = 6

Subtract 6 in both sides to isolate the variable:

-y = 0

0/-1 = 0

y = 0

Our answer would be x = 2 and y = 0

Answer:

(2,0)

Step-by-step explanation:

I'm going to use substitution since one of the variables in one of the equation is already solved for.

-y+3x=6

y=-6x+12

I'm going to replace the first y with the second y which is (-6x+12).

This gives me:

-(-6x+12)+3x=6

Distribute:

6x-12+3x=6

Combine like terms:

9x-12=6

Add 12 on both sides:

9x=18

Divide both sides by 9:

x=2

If x=2 and y=-6x+12, then y=-6(2)+12=-12+12=0.

The solution (the intersection) is (2,0).

Answer:

a) 3

b) 364

Step-by-step explanation:

A geometric sequence in explicit form is [tex]a_n=a_1 \cdot r^{n-1}[/tex] where [tex]a_1[/tex] is the first term and [tex]r[/tex] is the common ratio.

We are given:

[tex]a_5=9 \cdot a_3[/tex]

[tex]a_6+a_7=972[/tex].

What is a) r?

What is b) the sum of the first 6 terms?

So I'm going to use my first equation and use my explicit form to find those terms in terms of r:

[tex]a_1 \cdot r^4=9 \cdot a_1 \cdot r^{2}[/tex]

Divide both sides by [tex]a_1r^2[/tex]:

[tex]r^2=9[/tex]

[tex]r=\sqrt{9}[/tex]

[tex]r=3[/tex].

So part a is 3.

Now for part b).

We want to find [tex]a_1+a_2+a_3+a_4+a_5+a_6[/tex].

So far we have:

[tex]a_1=a_1[/tex]

[tex]a_2=3a_1[/tex]

[tex]a_3=3^2a_1[/tex]

[tex]a_4=3^3a_1[/tex]

[tex]a_5=3^4a_1[/tex]

[tex]a_6=3^5a_1[/tex].

We also haven't used:

[tex]a_6+a_7=972[/tex].

I'm going to find these terms in terms of r (r=3).

[tex]3^5a_1+3^6a_1=972[/tex]

[tex]243a_1+729a_1=972[/tex]

You have like terms to add:

[tex]972a_1=972[/tex]

Divide both sides by 972:

[tex]a_1=1[/tex]

The first term is 1 and the common ratio is 3.

The terms we wrote can be simplify using a substitution for the first term as 1:

[tex]a_1=a_1=1[/tex]

[tex]a_2=3a_1=3(1)=3[/tex]

[tex]a_3=3^2a_1=9(1)=9[/tex]

[tex]a_4=3^3a_1=27(1)=27[/tex]

[tex]a_5=3^4a_1=81(1)=81[/tex]

[tex]a_6=3^5a_1=243(1)=243[/tex].

Now we just need to find the sum of those six terms:

1+3+9+27+81+243=364.

=20.0

Step-by-step explanation:

We can first find the angle B using the sine rule as follows:

a/Sin A=b/Sin B

9/Sin 15=12/ Sin B

Sin B= (12 Sin 15)/9

=0.345

B=Sin⁻¹ 0.345

=20.18°

We then find C by using the summation of the interior angles of a triangle.

C=180-(20.18+15)

=144.82

Finding the length of c:

a/Sin A= c/ Sin C

9/Sin 15=c/Sin 144.82

c=(9 Sin 144.82)Sin 15

=20.0

Answer:

20.0 unit ( approx )

Step-by-step explanation:

Here,

ABC is a triangle in which,

m∠A=15°, a=9, and b=12,

By the law of sine,

[tex]\frac{sin A}{a}=\frac{sin B}{b}=\frac{sin C}{c}----(1)[/tex]

[tex]\frac{sin A}{a}=\frac{sin B}{b}[/tex]

[tex]\implies sin B=\frac{b sin A}{a}[/tex]

By substituting the values,

[tex]\implies sin B=\frac{12\times sin 15^{\circ}}{9}\approx 0.3451[/tex]

[tex]\implies B \approx 20.19^{\circ}[/tex]

Now, by the property of triangle,

m∠A + m∠B+ m∠C = 180°

⇒ m∠C = 180° - 15° - 20.19° = 144.81°,

By the equation (1),

[tex]c=\frac{b sin C}{sin B}=\frac{12\times sin 144.81^{\circ}}{sin 20.19^{\circ}}=20.0370532419\approx 20.0[/tex]

[tex]y=3x-4[/tex]

Interchange x and y as shown below

[tex]x=3y-4[/tex]

Solve the equation for y

[tex]x+4=3y\\\\y=\frac{x+4}{3}[/tex]

Therefore, the inverse of f(x) is given by

[tex]f^{-1}(x)=\frac{x+4}{3}[/tex]

C is the correct option.

The answer is:

Center: (-4,-4)

Radius: 2 units.

To solve the problem, using the given formula of a circle, we need to find its standard equation form which is equal to:

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

Where:

"h" and "k" are the coordinates of the center of the circle and "r" is its radius.

So, we need to complete the square for both variable "x" and "y".

The given equation is:

[tex]x^{2}+y^{2}+8x+8y+28=0[/tex]

So, solving we have:

[tex]x^{2}+y^{2}+8x+8y=-28[/tex]

[tex](x^2+8x+(\frac{8}{2})^{2})+(y^2+8y+(\frac{8}{2})^{2})=-28+((\frac{8}{2})^{2})++(\frac{8}{2})^{2})\\\\(x^2+8x+16 )+(y^2+8y+16)=-28+16+16\\\\(x^2+4)+(y^2+4)=4[/tex]

[tex](x^2-(-4))+(y^2-(-4))=4[/tex]

Now, we have that:

[tex]h=-4\\k=-4\\r=\sqrt{4}=2[/tex]

So,

Center: (-4,-4)

Radius: 2 units.

Have a nice day!

Note: I have attached a picture for better understanding.

The radius of the circle is 2 units.

To find the radius of the circle with equation x²+y²+8x+8y+28=0, we need to rearrange the equation into the standard form (x-h)²+(y-k)²=r², where (h,k) is the center of the circle and r is the radius. By completing the square, we can rewrite the equation as (x+4)²+(y+4)²=4.

Comparing this with the standard form, we can see that the center of the circle is (-4,-4) and the radius is √4 = 2. Therefore, the radius of the circle is 2 units.

Answer:

y=x

Step-by-step explanation:

We want a line parallel to y =x+42

The slope of y =x+42 is 1

Parallel lines have the same slope

We have the slope m=1 and a point (2,2)

We can use point slope form to write a line

y-y1 = m(x-x1)

y-2 = 1(x-2) point slope form

Changing to slope intercept form

y-2 = x-2

Add 2 to each side

y-2+2 = x-2+2

y=x

The line parallel to y = x + 42 travels through (2,2) can be represented by the equation y = x. This conclusion is based on the principles of line equations in a two-dimensional space, with slopes determining the parallelism of lines.

The subject of the question pertains to the formula of a line in a two-dimensional space. Specifically, you're asked to find a line that passes through the point (2,2) and is parallel to the line described by the equation y = x + 42.

In a standard equation of a line, y = mx + b, 'm' represents the slope of the line and 'b' indicates the y-intercept. Two lines are parallel if they have the same slope. Bearing this in mind, as the line y = x + 42 has a slope of 1 (since 1 is the coefficient of 'x'), the required line would also possess a slope of 1.

Substituting the point coordinates (2,2) into the equation y = mx + b (replacing 'm' with 1), gives us 2 = 2 + b. Solving for 'b', we find that it equals zero. Hence, the equation of a line parallel to y = x + 42 passing through the point (2,2) is y = x.

Answer:

The price decreased by 16 1/3%, or approximately 16.3%

Step-by-step explanation:

Use the formula for percent change. If the answer is negative, it is a percent decrease. if the answer is positive, it is a percent increase.

percent change = (new price - old price)/(old price) * 100%

In this case, use:

new price = 50

old price = 60

percent change = (new price - old price)/(old price) * 100%

percent change = (50 - 60)/60 * 100%

percent change = -10/60 * 100%

percent change = -1/6 * 100%

percent change = -100/6% = -50/3% = -16 1/3%

The price decreased by 16 1/3%, or approximately 16.3%

Absolute value means the distance between a number and 0.

Examples:

The absolute value of -7 is 7.

The absolute value of 5 is 5.

Key Concepts:

The absolute value sign is |x|, where x is any real number.

The absolute value removes any negative sign in front of a number.

Absolute value is an important math concept to understand. To represent the absolute value of a number, we use a vertical bar on either side of the number. Absolute value means "distance from zero" on a number line. Let's try an example to understand how absolute value works.

What is the absolute value of 4 and -4?

To find the absolute value of 4, we know that 4 is 4 units from zero on a number line. Therefore, the absolute value of 4 is 4.

For the absolute value of -4, we know that -4 is also 4 units from zero on the number line. Therefore, the absolute value of -4 is also 4.

Another way that I like to think about absolute value is no matter what number you have inside the absolute value, the result will always be positive. In other words, the absolute value of any number is the positive version of that number.

Answer:

Both of those are functions.

Step-by-step explanation:

Any upward or downward parabola is a function because they pass the vertical line test.

[tex]x=\pm \sqrt{1-y}{/tex]

Square both sides:

[tex]x^2=1-y[/tex]

Subtract 1 on both sides:

[tex]x^2-1=-y[/tex]

Multiply both sides by -1:

[tex]-x^2+1=y[/tex]

So this is a another parabola and it is faced down.  So this is also a function.

[tex]y=ax^2+bx+c[/tex] wit [tex]a \neq 0[/tex] willl always be a parabola.  

If [tex]a>0[/tex] then it is open up.

Answer:

C

Step-by-step explanation:

Parallel and opposite sides of a parallelogram are equal. Hence, we can say:

and

2y-10 = y +10

Solving first one, we get:

x + 30 = 2x - 10

30+10 = x

x = 40

Also

2y - 10 = y + 10

y = 10 + 10

y = 20

Now, z = x - y, so

z = 40 - 20 = 20

Answer C is right.

Since [tex]80\°<90\°[/tex], the angle provided in the first option is one of the other angles.

 Let's check the second option:

[tex]20\°+20\°+x=180\°\\x=140\°[/tex]

Since [tex]140\°>90\°[/tex], the angle provided in the second option is not one of the other angles.

[tex]0.0\overline{3}=\dfrac{1}{30}\\0.\overline{03}=\dfrac{1}{33}\\\\\dfrac{0.0\overline{3}}{0.\overline{03}}=\dfrac{\dfrac{1}{30}}{\dfrac{1}{33}}=\dfrac{1}{30}\cdot33=\dfrac{11}{10}=1\dfrac{1}{10}[/tex]

Answer:

q = -2

Step-by-step explanation:

-2x²-8x = 10 (divide both sides by -2)

x² + 4x = -5 (Apply completing the square method)

x² + 4x + (4/2)²= -5 + (4/2)²

x² + 4x + 2²= -5 + 2²    (reduce left hand side using a²+2ab+b² =  (a+b)² )

(x+2)² = -5 +4

(x+2)² = -1

(x+2)² + 1 = 0   (multiply both sides by -2)

(-2)(x+2)² + 1 (-2) = 0

-2[x - (-2)]² + (-2) = 0  ---> compare this with -2(x-p)² + q = 0

We can see that p = 2 and q = -2

The value of 'q' in the rearranged form of the given quadratic equation -2(x-p)²+q = 0 is -6. This is obtained by completing the square and comparing the equations.

Given the quadratic equation -2x² -8x = 10, it's rearranged to the form -2(x-p)²+q = 0. The objective is to find the value of 'q'.

To achieve this, you first need to rewrite the given equation -2x² -8x - 10 = 0 in the form -2(x-h)²+k = 0. This is called completing the square. The 'h' value here is equal to -b/2a, where 'b' is the coefficient of 'x' and 'a' is the coefficient of x². In this equation, a is -2 and b is -8 so h=(-(-8)/(2×(-2))=8/4=2.

Substituting h into the equation, you have -2(x-2)²+k=0. Now expand and simplify to get -2x²+8x-4+k=0. Comparing this with the original equation -2x² -8x -10 = 0, you can see that 'k' is equal to -10+4=-6, which is the 'q' value in the form -2(x-p)²+q = 0. So, the value of 'q' is -6.
