Answer:
5/4
Step-by-step explanation:
The probability that a randomly selected person at a show has seen the band play live before is 30%. A "superfan" is defined as someone who has seen the band play live at least 10 times. The probability that a person at a show is a "superfan" is 20%. Two people are selected at random. What is the probability that both people have both seen the band perform live before, and are superfans?
Answer:
0.09 and 0.04
Step-by-step explanation:
The probability that a randomly-selected person at a show has seen the band play live before is 30%=0.30
The probability that a person at a show is a "superfan" is 20%=0.20
Two people are selected at random.
The probability that both people have both seen the band perform live before = The probability that the first person has seen the band live before and the second person also has seen the band live before.
=0.30 x 0.30
=0.09
Similarly, the probability that both are "superfans" = The probability that the first person is a superfan and the probability that the second person is a superfan.
=0.20 x 0.20
=0.04
Hence, the probability that both people have both seen the band perform live before, and are "superfans" are 0.09 and 0.04 respectively.
Solve for the values of x:
(2x-1)(x+4) = 0
Step-by-step explanation:
x = -4, 1/2 is the value of x
The values of x that satisfy the equation (2x - 1)(x + 4) = 0 are
x = 1/2 and x = -4.
Here, we have,
To solve for the values of x in the equation (2x - 1)(x + 4) = 0, we can use the zero-product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be zero.
So, we set each factor equal to zero and solve for x:
2x - 1 = 0
Adding 1 to both sides:
2x = 1
Dividing both sides by 2:
x = 1/2
x + 4 = 0
Subtracting 4 from both sides:
x = -4
Therefore, the values of x that satisfy the equation (2x - 1)(x + 4) = 0 are x = 1/2 and x = -4.

How many solutions y=5x-4 y=5x-5
Answer:
No solution
Step-by-step explanation:
Any equations with the same slope are parallel, or will never intersect.
In a slope-intercept equation, this would mean the 'm' values are the same.
y = mx + b
Two equations:
y = 5x - 4
y = 5x - 5
Since the two equations given have the same slope, they will never intercept and therefore have no solution.

Answer:
37 degrees
Step-by-step explanation:
All insides of triangles = 180 degrees, so...
67 degrees + 76 degrees + (x + 48) degrees = 180
67 + 76 + (x + 48) = 180
143 + x + 48 = 180
191 + x = 180
x = -11
x + 48
-11 + 48

I need to know the missing angles
Answer:
71
Step-by-step explanation: 2x=142
x=71
Answer:
the missing angles are 71
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
142° is an exterior angle of the triangle, thus
x + x = 142
2x = 142 ( divide both sides by 2 )
x = 71

9. ∠DEF and ∠FEG are complementary. m∠DEF = (3x − 4)°, and m∠FEG = (5x + 6)°.
Find the measures of both angles.
Answer:
29°61°Step-by-step explanation:
Complementary angles are two angles that add up to be 90 degrees.
We can write an equation and solve for x.
(3x - 4) + (5x + 6) = 90
~Combine like terms
8x + 2 = 90
~Subtract 2 to both sides
8x = 88
~Divide 8 to both sides
x = 11
Angle DEF:
3x − 4
3(11) - 4
33 - 4
29°
Angle FEG:
5x + 6
5(11) + 6
55 + 6
61°
Check:
29 + 61 = 90°
