Answer: The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive (i.e., they cannot occur simultaneously).
Step-by-step explanation: All we have to do is multiply the events together to get the total number of outcomes. Using our example above, notice that flipping a coin has two possible results, and rolling a die has six possible outcomes. If we multiply them together, we get the total number of outcomes for the sample space: 2 x 6 = 12!
Answer: A: Flipping a Flair, two-sided coin

Which is an equation of a direct proportion?
The correct answer is y = -2x.
Direct proportion can also be known as Direct variation. When the ratio of two quantities equals constant, we call it Direct Proportion. Direct Proportion is denoted by [tex]\alpha[/tex] .
Let us consider two quantities a and b, then the direct proportion between a and b can be expressed as,
a [tex]\alpha[/tex] b
=> [tex]a/b = k[/tex] ( where k is constant)
=> [tex]a = kb[/tex] [tex]--- >[/tex] 1
Substitute a=x and b=y in 1, and then we get
[tex]x = ky[/tex]
Therefore, the general form of an equation which satisfies direct proportion is x = ky.
[tex]y=1/2x-2, y=-2x+3,y=4/x[/tex] are not in the form of [tex]x = ky[/tex].
So, The equation of direct proportion is y = -2x.

. If Ashley pays $6, what was the original price?
Answer:
$8
Was the original price.
Step-by-step explanation:

Draw a right-angled isosceles triangle and write its measures.
Answer:
45 ∘,45 ∘ ,90 ∘
Step-by-step explanation:
Since, the angle is right angled isosceles triangle. One of the angles will be 90 ∘
. let the other two angles be x
Thus, sum of angles = 180
90+x+x=180
2x=90
x = 45 ∘
The measure of each angle is: 45 ∘ ,45 ∘ ,90 ∘

Prisha: 6 meters & 3 seconds
Step-by-step explanation:
Marc: If Marc travels 8 meters in 4 seconds it means that he has a speed of 2m/s
Prisha: If Prisha travels 6 meters in 3 seconds it means that she has a speed of 2m/s
To find speed we simply have to divide distance by time

The table shows a proportional relationship between x and y.
x 12 18 30
y 4 6 10
Describe the graph of the proportional relationship, in words.
A line beginning at point (12, 4) and continuing through the point (10, 30).
A line beginning at point (12, 4) and continuing through the point (6, 18).
A line beginning at point (0, 0) and continuing through the point (30, 10).
A line beginning at point (0, 0) and continuing through the point (4, 12).
A line beginning at point (0,0) and continuing to (30,10)
A proportional relationship will always go through the origin so you can eliminate the first two. In the last one the second coordinate is (4,12) which is wrong because the x is 12 and the y is 4. So that is how you know the 3rd option is correct :)

Write 5 ratio equivalent to 9:13?
Answer:
18:2627:3936:5245:6554:78Step-by-step explanation:
Given ratio,
→ 9:13
The 5 equivalent ratios are,
→ (9 × 2):(13 × 2) = 18:26
→ (9 × 3):(13 × 3) = 27:39
→ (9 × 4):(13 × 4) = 36:52
→ (9 × 5):(13 × 5) = 45:65
→ (9 × 6):(13 × 6) = 54:78
Hence, these are the ratios.

If x and y are in direct proportion and y is 80 when x is 10, find y when xx is 15.
Answer:
y = 120
Step-by-step explanation:
If x = y, they can be written as a fraction to show their proportionality as [tex]\frac{10}{80}[/tex]. This is equal to [tex]\frac{1}{8}[/tex], so when x = 1, y = 8. To find when y is equal to x when x = 15, just multiply y by 15. 15(8) = 120, so y = 120 when x = 15.
Answer:
120
Step-by-step explanation:
set up a proportion: 80/10=y/15
solve: 80*15=10y
1200=10y
y=120
