Answer:
The probability that exactly one of the selected adults says that he or she was too young to get tattoos is 0.4096.
Step-by-step explanation:
Let X denote the number of adults who says that he or she was too young to get tattoos.
The probability of selecting an adults who says that he or she was too young to get tattoos is, p = 0.20.
Five adults who regret getting tattoos are randomly selected.
The events of any of these five adults regretting getting tattoos is independent of each other.
The random variable X follow a Binomial distribution with parameters n = 5 and p = 0.20.
Compute the probability that exactly one of the selected adults says that he or she was too young to get tattoos as follows:
[tex]P(X=x)={5\choose x}(0.20)^{x}(1-0.20)^{5-x}\\\\P(X=1)={5\choose 1}(0.20)^{1}(0.80)^{5-1}\\\\[/tex]
[tex]=5\times 0.20\times 0.4096\\\\=0.4096[/tex]
Thus, the probability that exactly one of the selected adults says that he or she was too young to get tattoos is 0.4096.

Determine the slope of a line that passes through the points (-2,8) and (3,4)
Answer:
m= -4/5
Step-by-step explanation:
Use the slope formula to find the slope m .
Slope formula:
m=slope
(x_1, y_1) =coordinates of first point in the line
(x_2, y_2)=coordinates of second point in the line
m = (y2 -- y1) / (x2 -- x1).

if k-9=5(k-3)find k
Answer:
K = 3/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
k−9=5(k−3)
k+−9=(5)(k)+(5)(−3)(Distribute)
k+−9=5k+−15
k−9=5k−15
Step 2: Subtract 5k from both sides.
k−9−5k=5k−15−5k
−4k−9=−15
Step 3: Add 9 to both sides.
−4k−9+9=−15+9
−4k=−6
Step 4: Divide both sides by -4.
-4k/-4 = -6/-4
K = 3/2

Determine the domain on which the following function is increasing.
Answer:
(-∞, -2]
Step-by-step explanation:
Domain of a function is defined by the x-values (Input values) and y-values define It's range.
From the graph of a parabola,
Graph shows the increase in the value from x = -∞ to x = -2 then the values are decreased from x = -2 to ∞.
Therefore, domain in which the function is increasing : (-∞ , -2]

Answer:
34
Step-by-step explanation:
ABD = 79
ABD = DBC + CBA
79 = (8x - 3) + (5x + 4)
combine like terms
79 = 13x + 1
goal is to isolate variable
subtract 1 from both sides
78 = 13x
divide both sides by 13
6 = x
plug x value into expression given for DBC

Find the midpoint between the pair of points using the Midpoint
Formula. *
(7,-2) and (-4, 2)
Given parameters:
Coordinates = (7,-2) and (-4, 2)
The formula for the coordinate of the mid point is;
[tex]x_{m}, y_{m}[/tex] = ( [tex]\frac{x_{1} + x_{2} }{2} , \frac{y_{1} + y_{2} }{2}[/tex] )
where;
[tex]x_{m}, y_{m}[/tex] are the coordinates of the mid points
x₁ = 7 y₁ = -2
x₂ = -4 y₂ = 2
Input the parameters and solve;
[tex]x_{m}, y_{m} = \frac{7 + (-4)}{2} , \frac{-2 + 2}{2}[/tex]
[tex]x_{m}, y_{m}[/tex] = [tex]\frac{3}{2} , 0[/tex]
So the mid point is at [tex]\frac{3}{2} , 0[/tex]
solve for m p=mnq, whats the answer
Easy buddy...
[tex]p = m \times n \times q[/tex]
Divided the sides of the equation by n
[tex] \frac{p}{n} = m \times q \\ [/tex]
Divided the sides of the equation by q
[tex] \frac{p}{n \times q} = m \\ [/tex]
So
[tex]m = \frac{p}{nq} \\ [/tex]
