In a group of people, some are in favor of a tax increase on rich people to reduce the federal deficit and others are against it
1 answer:
Answer:
There will be 8 possible outcomes.
Step-by-step explanation:
(Assume that there is no other outcome such as "no opinion" and "do not know.")
3 persons are selected at random from this group and their opinions in favor or against raising such taxes are noted.
So, the number of possible outcomes are =
YYY, YYN, YNY, NYY, YNN, NNY, NYN, NNN
Y = Yes and N = No
Therefore, there will be 8 possible outcomes.

Answer:
Part a)
Part b) The total cost is
Part c) see the explanation
Step-by-step explanation:
Part a) Write a linear equation to represent this situation
Define the variables
Let
x ----> the number of hours
y ----> the total cost in dollars
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or the unit rate
b is the y-intercept or initial value (value of y when the value of x is equal to zero)
In this problem we have that
The unit rate or slope is equal to
The y-intercept or initial value is equal to
substitute
Part b) Use the equation to find the total cost to rent skis from 8:30 am to 3:00 pm
Remember that
3:00 pm=15:00
so
from 8:30 am to 3:00 pm, the total hours is equal to
15:00 -8:30=6:30=6.5 h
For x=6.5 h
substitute in the linear equation and solve for y
Part c) What does your answer mean in context of the problem?
we have that
y=220.25
That means -----> The total cost to rent skis for 6.5 hours is equal to $220.25
Given :
A circle is inscribed in a square with a side length of 144.
So, radius of circle, r = 144/2 = 72 units.
To Find :
The probability that the point is inside the circle.
Solution :
Area of circle,
Area of square,
Now, probability is given by :
Therefore, the probability that the point is inside the circle is 0.785 .
