Step-by-step explanation:
As 300 tickets are sold , the probability of being a winner is = 
The prize value is $64 or 
= 0.213
The cost of ticket you paid = $4
Hence, the expected value of one ticket = 0.213-4 = -3.787 or rounding off we get -3.79
Answer: Amounts
Step-by-step explanation:
Time series analysis are the method which are used by researchers to analyze the time series data so as to get the features of the data and to also derive meaningful statistics.
A linear trend equation is used to represent time series values when the data are changing by equal amounts.
Answer:
D.
Step-by-step explanation:
We can see from our graph that triangle CED is similar to triangle CBA. Side length BA corresponds to ED and Side length AC corresponds to DC.
Since we know that corresponding sides of two similar triangle are in the same proportion. To find value of x we will set proportion of the corresponding sides of our given triangles equal.
Upon cross multiplying our given equation we will get,

Upon distributing 7 we will get,




Therefore, x equals 8.57 and option D is the correct choice.
Answer:
<u>Therefore, the value of x is 5.</u>
Step-by-step explanation:
We can match each equation to find the solutions.



Now, we need solve this quadratic equation.

<u>Therefore, the value of x is 5.</u>
