Answer:
The answer is A.
Step-by-step explanation:
The sample space is all possible outcomes.
The sample space of the experiment is given by set C = { HR , HG , HB , TR , TG , TB }
What is Set Theory Formula?The set formula is given in general as n(A∪B) = n(A) + n(B) - n(A⋂B), where A and B are two sets and n(A∪B) shows the number of elements present in either A or B and n(A⋂B) shows the number of elements present in both A and B.
Given data ,
Let the first experiment be represented as set A
where the tossing of coins has 2 outcomes
A = { Heads ( H ) , Tails ( T ) }
Let the second experiment be represented as set B
where the number of balls = 3
B = { Red ( R ) , Green ( G ) , Blue ( B ) }
Now , You toss a coin and randomly pick a ball
The sample space contains a heads or tails of the coin accompanied by the color of the ball
The total number of elements = 3 x 2 = 6 elements
So , the sample space is given by set C = { HR , HG , HB , TR , TG , TB }
Hence , the set is C = { HR , HG , HB , TR , TG , TB }

What is the solution to the equation 6y –2(y + 1) = 3(y – 2) + 6?
y = –10
y = –2
y = 2
y = 6
Answer:
y = 2
Step-by-step explanation:
6y - 2(y + 1) = 3(y - 2) + 6
6y - 2y - 2 = 3y - 6 + 6
6y - 2y - 2 = 3y
4y - 2 = 3y
4y - 2 + 2 = 3y + 2
4y = 3y + 2
4y - 3y = 3y - 3y + 2
y = 2
What is the value for X?
Answer:
5
Step-by-step explanation:
6x + 4 + 73 + 73 = 180
6x + 150 = 180
6x = 30
x = 5
Those little marks on AB and BC denote congruence. That makes the triangle isoceles. That means the base angles are equal. Both 73.
Triangle Sum Theory states all angles of a triangle add to 180.

Suppose a normal distribution has a mean of 48 abd a standard deviation of 5. What is the probability that a data value is between 48 and 52?
Answer:
P(48<x<52) = 0.2881
Step-by-step explanation:
P(48<x<52) = normalcdf(lower,upper,µ,σ) = normalcdf(48,52,48,5) ≈ 0.2881
Therefore, the probability that a data value is between 48 and 52 is 0.2881, or about a 28.81% chance of occurrence.
1. Find measure of angle GBC
A. 55°
B. 125°
C. 45°
D. 60°
(Show work)
Answer:
A. 55°
Step-by-step explanation:
So the line goes through two angles, 125° and 55°
Lets check, does the angle look larger than 90°
Remember, 90° mean the line is perpendicular, or goes straight up.
I see that it is not. The angle that is less than 90° (55°) is correct.

The graph of y=f(x) is the solid black graph below. Which function represents the dotted graph?
Answer:
y = f(x-2) + 1
Step-by-step explanation:
The original functions looks like f(x) = |x|
For the new function the vertex has shifted -2 left (x) and up +1 (y)
So
y = f(x-2) + 1
Given m
|| n, find the value of x.
m
n
126°
(8x+6)
Answer:
6
Step-by-step explanation:
since m is parallel to n, they both also have the same angles at the intersection with the crossing line.
the total angle on one side of a line is simply a half circle = 180 degrees (the angle of flipping over from laying flat in one direction of the line to laying flat in the other direction of the line).
so, the two angles of m with the intersecting line are
126 degrees and
(8x + 6) degrees.
and their sun must be 180.
126 + (8x+6) = 180
132 + 8x = 180
8x = 48
x = 6

D'andre was trying to make a rectangular frame that had a width of 24 inches and a length of 70 inches. He wanted to ensure his shape contained right angles, so he measured the diagonal and found that it was 74 inches long. Did D'andre construct a rectangle? Why or why not?
Answer:
yes
the sum of the squares of the width and length is equal to the square of the diagonal
Step-by-step explanation:
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
24^2 + 70^ = 576 + 4900 = 5476
square root = 74
The mean of ten numbers is 58. If one of the numbers is 40,
what is the mean of the other nine?
60
if the mean of ten numbers is 58 then the total would be 580 and when you subtract 40 from 580 you get 540 and then divide 540 by 9 for the new mean of 60

The equation is 15*w*14 = 2730
We simply multiply length, width and height to get the volume of the rectangular block.
That equation becomes 210w = 2730 because 15*14 = 210
From here, we divide both sides by 210
You should end up with w = 13
As a check, 15*w*14 = 15*13*14 = 2730 which confirms we have the correct replacement for w.

Organize from least to greatest
Answer:
y=31x/15 < y=27x/13 < y=15x/7 < y=13x/6 < y=11x/5 < y=21x/9 (=7x/3) < y=19x/8
Step-by-step explanation:
since all equations base on a linear, simple expression of x, we can simply compare the fractions.
in general, the bigger the number at the bottom, the smaller the individual fraction. that is our first indicator.
we then notice that many fractions represent the value of 2 plus one fraction.
31/15 = 2 1/15
27/13 = 2 1/13
15/7 = 2 1/7
13/6 = 2 1/6
11/5 = 2 1/5
the only exceptions are 21/9 and 19/8
but 21/9 is actually 7/3 = 2 1/3
and fits therefore into the list above.
that leaves 19/8 = 2 3/8.
the list above can be sorted based on the single fraction at the end (remember, the bigger the number at the bottom, the smaller the value). so, from least to greatest :
2 1/15 (31/15)
2 1/13 (27/13)
2 1/7 (15/7)
2 1/6 (13/6)
2 1/5 (11/5)
2 1/3 (7/3 = 21/9)
where did now 2 3/8 fit in ?
well, 3/8 is almost 1/2 (so, relatively big), and we start our comparison with the biggest number in the list so far :
1/3 (from 2 1/3).
what is bigger - 1/3 or 3/8 ?
let's find the smallest number that can be divided by 3 and by 8. that would be 24. so now we bring both fractions to the same base of 24.
1/3 = 8/24
3/8 = 9/24
=> 3/8 > 1/3
and therefore, 19/8 is the largest value and at the end of the list.
