When buying a candy bar, there is a 20% chance that it will also include a coupon for a second candy bar. A student
2 answers:
<h2>Answer:</h2>
- To estimate the probability that more than 2 out of 7 candy bars will include a coupon, the student must count the number of trials with more than two 1's. and divide by the number of trials.
- This gives an estimated probability of about 0.1875.
1 represent a candy bar with a coupon and numbers 2 through 5 represent a candy bar without a coupon.
Now we are asked to find the probability that, if she buys 7 candy bars, more than 2 will include a coupon.
Total number of outcomes=16
Number of favorable outcomes(i.e. the outcome which have more than 2 one) = 3
( Since the outcomes are: 2113415 4341112 1455141 )
Hence, the probability is the ratio of Number of favorable outcomes to the total number of outcomes.

Answer:
Both lines are equal (they are the same)
<em></em>
Step-by-step explanation:
Given
Required
What is true about graph of both lines
<em>Questions like this are better solved when there's option(s) to select from. However, some of the properties of line equation that I'll consider are to check if both lines are either parallel or perpendicular</em>
<em />
To do this,
The first thing to do is to calculate the slope of both lines
Add 8 to both sides
Divide both sided by 3
The slope of the line is the coefficient of x;
Solve for the y intercept; <em>Let x = 0</em>
Solve for the x intercept; <em>Let y = 0</em>
Subtract from both sides
Subtract both sides by
------------------------------------------------------------------------------------------------------
Divide both sides by 6
Simplify fractions to lowest term
The slope of the line is the coefficient of x;
Solve for the y intercept; <em>Let x = 0</em>
Solve for the x intercept; <em>Let y = 0</em>
Subtract from both sides
Subtract both sides by
-------------------------------------------------------------------------------------------------------
By comparing the slope, x intercept and y intercept of both lines;
It'll be observed that they have the same slope, x intercept and y intercept
<em>This implies that both lines are equal; in other words, they are the same.</em>
