two fair dice are rolled. the score is the difference between the two dice. some of the possible scores are shown in the table.
c) which score has a probability of occurring 1/18

Answers

Answer:

Step-by-step explanation:

a). From the table attached,

   Number in 1st column and 1st row = 1 - 1 = 0

   Number in 1st column and 6th row = 6 - 1 = 5

   Number in 2nd column and 4th row = 4 - 2 = 2

   Number in 5th column and 2nd row = 5 - 2 = 3

   Number in 6th column and 5th row = 6 - 5 = 1

b). Probability of scoring 1 = [tex]\frac{\text{Preferred outcome}}{\text{Total outcomes}}[/tex]

   Preferred outcomes of getting = 10

   Total outcomes = 36

   Probability of scoring 1 = [tex]\frac{10}{36}[/tex]

                                          = [tex]\frac{5}{18}[/tex]

c). Probability of occurring a score = [tex]\frac{1}{18}[/tex]

                                                         = [tex]\frac{1\times 2}{18\times 2}[/tex]

                                                         = [tex]\frac{2}{36}[/tex]

                                                         = [tex]\frac{\text{Preferred outcome}}{\text{Total outcomes}}[/tex]

   Since, 5 is a number which has occurred twice

   Score that has a probability of occurring of [tex]\frac{1}{18}[/tex] is 5.

QUICK! how do i do this i need the x and y this is the Systems of equations with substitution

Answers

Answer:

x=1/15 y = -4 1/3

Step-by-step explanation:

First combine like terms.

-3y = 13

y= -13/3

y= -4 1/3

Substitute for y in next equation

-4 1/3 = 5x - 4

5x = 4 1/3 - 4

5x = 4 1/3 - 4

5x = 1/3

x = 1/3 divided by 5

Since fractions can't be divided, multiply by the inverse

x = 1/3 times 1/5 = 1/15

If an item has an original price of $80 and has been discounted 20%, what is the sale price?

Answers

Answer:

$64

Step-by-step explanation:

Since 20% is 0.20 and a whole is 1.00, to discount the price, we have to subtract the whole value by the discount value 1.00-0.20=0.80

Then we have to find 80% of 80

80%=0.80

0.80*80=64

The sale price is $64

Answers

Answer:

(1,1) and (7,5) => Slope: 2/3

(1,1) and (5,7) => Slope: 3/2

(2,5) and (-1,2) => Slope:1

(2,5) and (-7,-4) => Slope:1

Step-by-step explanation:

The slope of a line is denoted by m and is given as:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Calculating the slope one by one for each pair.

(1,1) and (7,5):

Let m1 be the slope of this line

Here

(x1,y1) = (1,1)

(x2,y2) = (7,5)

Putting values in formula

[tex]m_1 = \frac{5-1}{7-1}\\= \frac{4}{6}\\=\frac{2}{3}[/tex]

(1,1) and (5,7):

Let m2 be the slope of this line

Here

(x1,y1) = (1,1)

(x2,y2) = (5,7)

Putting values in formula

[tex]m_2 = \frac{7-1}{5-1}\\m_2=\frac{6}{4} = \frac{3}{2}[/tex]

(2,5) and (-1,2):

Let m3 be the slope of this line

Here

(x1,y1) = (2,5)

(x2,y2) = (-1,2)

Putting values in formula

[tex]m_3 = \frac{2-5}{-1-2}\\m_3 = \frac{-3}{-3} = 1[/tex]

(2,5) and (-7,-4):

Let m4 be the slope of this line

Here

(x1,y1) = (2,5)

(x2,y2) = (-7,-4)

Putting values in formula

[tex]m_4 = \frac{-4-5}{-7-2}\\m_4 = \frac{-9}{-9} = 1[/tex]

Hence,

The points and their respective slopes are as follows:

(1,1) and (7,5) => Slope: 2/3

(1,1) and (5,7) => Slope: 3/2

(2,5) and (-1,2) => Slope:1

(2,5) and (-7,-4) => Slope:1

Which statement is correctly written as a conditional statement?

A) Any four-sided shape is a quadrilateral.
B) A shape has four sides when it is a quadrilateral.
C) If a shape has four sides, then it is a quadrilateral.
D) A shape has four sides, or it is a quadrilateral.

Answers

Answer:

C

Step-by-step explanation:

If a shape has four sides, then it is a quadrilateral.

If a shape has four sides, then it is a quadrilateral so option (C) will be correct.

What is quadrilatereal?

A quadrilateral is a geometrical 2d shape in which there are four sides and each side is connected and makes a close polygon.

In other meaning, a quadrilateral is a kind of polygon in which four sides for example rectangle, square, and parallelogram are quadrilateral.

a quadrilateral is a four-sided polygon, having four edges and four corners

A parallelogram is a basic quadrilateral with two sets of parallel sides.

The confronting or opposing sides and the opposing angles of a parallelogram are of equal length.

A quadrilateral is a quadrilateral because it has four sides not because it is quadrilateral so it has four sides.

For example, 4 sides are equal so the square is not due to the square all lines will same.

Hence If a shape has four sides, then it is a quadrilateral.

Find the slope of a line with the given points

Answers

Answer:

C) 0

Step-by-step explanation:

Hi there!

We are given these two points: (11, -10), and (-16, -10)

We want to find the slope of these two points
The formula for the slope (m) calculated from two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have 2 points, but let's label their values to avoid any confusion.

[tex]x_1=11\\y_1=-10\\x_2=-16\\y_2=-10[/tex]
Now substitute these points into the formula (remember: the formula has SUBTRACTION)

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-10--10}{-16-11}[/tex]

simplify

m=[tex]\frac{-10+10}{-16-11}[/tex]

m=[tex]\frac{0}{-27}[/tex]

divide

m=0

The answer is 0, which is option C.

Hope this helps!
