Answer:
0.150,0.595
Step-by-step explanation:
Given that at a self-service gas station, 40% of customers pump regular gas, 35% pump midgrade, and 25% pump premium gas. Of those who pump regular, 30% pay at least $30. Of those who pump midgrade, 50% pay at least $30. And of those who pump premium, 60% pay at least $30.
Regular gas Midgrade Premium gas Total
Percent 40 35 25 100
atleast 30 30% 50% 60%
a) The probability that the next customer pumps premium gas and pays at least $30
=
b) the probability that the next customer pays at least $30
= P(regular and pays atleast 30%)+P(premium and pays atleast 30%)+P(midgrade and pays atleast 30%)
=
Answer:
So since we have 2^-2 We can do 1/2^2 = 0.25
So if you have y^-x = 1/y^x
First of all we know the
Absolute Value Function that is:
This is called the
Parent Function <em>of the Absolute Value Function.</em>
From the equation:
The term:
means that the the Parent Function is <em>shifted</em>
two units <em>to the left</em>.
On the other hand, the term:
means that the function
is <em>shifted</em>
three units <em>downward. </em>So the result is the graph shown below
Answer:
24 times
Step-by-step explanation:
P(5 or 6) = 2/6
2/6 = x/72
cross-multiply:
6x = 144
x = 24
Answer:
Hi there!
The correct answer is: There is a moderately strong, negative, nonlinear between two variables. There is one outlier around (3,40)
Step-by-step explanation:
The association in a scatter plot should always include a description of the <u>form</u>, <u>direction</u>, and <u>strength</u> of the association.
Form: Is the association linear or nonlinear?
Direction: Is the association positive or negative?
Strength: Does the association appear to be strong, moderately strong, or weak?
Outliers: Do there appear to be any data points that are unusually far away from the general pattern?
