The probability of rolling exactly  one six = 0.04

what is probability ?

Probability is a branch of mathematics that deals with the occurrence from of a random event . the value is expressed from zero to one .Probability has been introduced in mathematics  to predict how likely events are to happen .

So , acc the question "exactly one six " means  that one roll so that probability must be doubled the probability of " not six " is 4/5 . the probability of a 6 on the roll and not on the second is 1/5 x 4/5 =4/ 25 .

The six could come on the second roll so thst probability must be doubled .

the overall probability of exactly one six 8/25 or 0.32

completing toatl probability -no sixes =4/25 x 4/25 =16/25 =0.04

two sixes =1/5x 1/5 =1/25= 0.04

Hence , the probability of rolling exactly one six = 0.04

How to determine the area of the composite figure

The formula for determining the area of a rectangle is expressed as;

Area = lw

Where;

l is the length of the rectanglew is the width of the rectangle

From the figure shown, we have two rectangles

Area of the bigger rectangle;

Length = 9

Width = 6

Now, substitute the value

Area = 9(6)

Multiply through

Area = 54 square units

Area of the smaller rectangle

Length = 9 - 7 = 2

Width = 9 - 6 = 3

Substitute the values

Area = 2(3)

Multiply through

Area = 6square units

The formula for area of a triangle is expressed as;

Area = 1/2 base× height

Base = 9 - 6 = 3

Height = 9 - 2 = 3

Substitute the value

Area = 1/ 2 ×2(3)

Area = 6/ 3

Area = 2

What is the value of z in the system shown below?
x+y+z=6
x + 2y = 5
2x+z = 5

Answers

Answer:  z = 3

========================================================

Explanation:

I'll use the substitution method to solve this system of equations.

Solve the third equation for z

2x+z = 5

z = 5-2x

Then solve the second equation for y

x+2y = 5

2y = 5-x

y = (5-x)/2

y = -0.5x+2.5

Plug each of these into the first equation so we can solve for x.

x+y+z = 6

x+(-0.5x+2.5)+(5-2x) = 6

-1.5x+7.5 = 6

-1.5x = 6-7.5

-1.5x = -1.5

x = (-1.5)/(-1.5)

x = 1

Let's use this to find y and z

y = -0.5x+2.5 = -0.5*1+2.5 = 2

z = 5-2x = 5-2*1 = 3

Therefore,

x = 1

y = 2

z = 3

Or we can write it like this:  (x,y,z) = (1,2,3)

-------------------

Check:

Plug these values into equation 1 and simplify

x+y+z = 6

1+2+3 = 6

6 = 6

We get the same thing on both sides.

This confirms equation 1.

Repeat for equation 2.

x+2y = 5

1+2*2 = 5

1+4 = 5

5 = 5

This confirms equation 2.

Lastly, plug those values into equation 3

2x+z = 5

2*1+3 = 5

2+3 = 5

5 = 5

Equation 3 is confirmed.

All three equations are true when (x,y,z) = (1,2,3). The solution is fully confirmed.

How to calculate the length?

It should be noted that the perimeter of a rectangle is illustrated as:

= 2(length + width)

In this case, the width is given as 7/2 = 3.5 feet.

It should be noted that the perimeter is given as 20 feet.

Therefore, the length will be:

2(length + width) = 30

2(length + 3.5) = 20

2Length + 7 = 20

2L = 20 - 7

2L = 13

L = 13/2

L = 6.5

Therefore, the length is 6.5 feet.

Write the equation of the line that goes through the point (3,-3) and has a slope of -5/3 (in slope intercept form).

Answers

The equation of the line that goes through the point (3,-3) and has a slope of -5/3 is y=(-5x+6)/3.

What is a slope?

In mathematics, line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent a slope; reason for this is unclear, although it is first used in English by O'Brien in 1844, who wrote the equation for a straight line as "y = mx + b," and by Todhunter in 1888, who wrote it as "y = mx + c."

The ratio of "vertical change" to "horizontal change" between (any) two unique points on a line is used to compute slope. The ratio can also be written as quotient ("rise over run"), which produces same number for every two distinct points on the same line. A declining line has negative "rise." The line might be useful, as determined by road surveyor, or it might appear in a diagram that represents a road or a roof as a description or a design.

The slope's absolute value serves as a gauge for  line's steepness, incline, or grade. A steeper line is indicated by slope with a higher absolute value. A line can be drawn with one of four directions: upward, downward, horizontal, or vertical.

if we let y = mx + b, where m is the slope and b is the intercept, and y - y1 = m (x - x1), then:

3(y + 3) = - 5 (X - (-3))

3y + 9 = - 5 X + 15

3y = -5 X + 6

y=(-5x+6)/3

Check:

When x = 3, y should equal - 3, so:

Y = (- 5 (3) + 6)/3 = -3

Also, we can prove that if the alternate exterior angles are congruent, then the lines they lie on are parallel lines, using the converse of the alternate exterior angles theorem.

Thus, we are given that angle 2 = angle 6. Angles 2 and 6 lie on lines d and e. Since they are equal to each other, they are congruent angles. Therefore, lines d and e are parallel lines based on the converse of the alternate exterior angles theorem.
