Answer:
0.11% probability that you must ask 20 people to find one person without a social networking site
Step-by-step explanation:
We have these following probabilities:
75% probability that a millenial has a profile in a social netwok site.
25% probability that a millenial does not have a profile in a social network site.
What is the probability that you must ask 20 people to find one person without a social networking site?
The first 19 people have a social network site, each with a 75% probability.
The 20th person does not have a profile, with a 25% probability.
So
![P = (0.75)^{19}*0.25 = 0.0011](https://tex.z-dn.net/?f=P%20%3D%20%280.75%29%5E%7B19%7D%2A0.25%20%3D%200.0011)
0.11% probability that you must ask 20 people to find one person without a social networking site
Answer:
The equation of this line would be y = -1/2x + 1
Step-by-step explanation:
In order to find this equation we must first find the slope of the original line. To do this, we need to solve the original equation for y.
2x + 4y = 16
4y = -2x + 16
y = -1/2x + 4
The original slope (the coefficient of x) is -1/2, which means the new slope will also be -1/2 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line.
y - y1 = m(x - x1)
y - 2 = -1/2(x + 2)
y - 2 = -1/2x - 1
y = -1/2x + 1

Answer:
$2942.27
Step-by-step explanation:
Given the circumference of a circle, we can get the radius which will then help us get the area and finally estimate the cost of tiling.
C=2πr
Where C is circumference and r is radius
Making r the subject of the formula then
r=C/2π
Substituting 157 ft for C then
r=157/2π=24.9873260654276 ft
Area, A is given by A=πr²
A=π*(24.9873260654276)²=1961.50509613606
Rounded off, the area is 1961.51 ft²
Given the cost per unit square foot as $1.5 then the overall cost will be
$1.5*1961.51=$2,942.265
Rounded off as $2942.27
