Answer:
For this case the probability of getting a head is p=0.61
And the experiment is "The coin is tossed until the first time that a head turns up"
And we define the variable T="The record the number of tosses/trials up to and including the first head"
So then the best distribution is the Geometric distribution given by:

Step-by-step explanation:
Previous concepts
The geometric distribution represents "the number of failures before you get a success in a series of Bernoulli trials. This discrete probability distribution is represented by the probability density function:"
Let X the random variable that measures the number os trials until the first success, we know that X follows this distribution:
Solution to the problem
For this case the probability of getting a head is p=0.61
And the experiment is "The coin is tossed until the first time that a head turns up"
And we define the variable T="The record the number of tosses/trials up to and including the first head"
So then the best distribution is the Geometric distribution given by:

Answer:
y = 2x² - 10
Step-by-step explanation:
We must find a pattern in the numbers. Set out the numbers in a table (Columns 1 and 2 in the table).
<u>x</u> <u> y</u> <u>y/2</u> <u>y/2 + 5
</u>
2 -2 -1 4
3 8 4 9
4 22 11 16
5 40 20 25
It looks like all y-values are multiples of 2.
Let's divide them by 2 (Column 3).
The numbers don't increase evenly. We may have a quadratic function.
If we add 5 to each quotient, we get a set of values equal to x² (Column 4).
y/2 + 5 = x²
y + 10 = 2x²
y = 2x² - 10
The function is y = 2x² - 10.
We have been given that a person places $6340 in an investment account earning an annual rate of 8.4%, compounded continuously. We are asked to find amount of money in the account after 2 years.
We will use continuous compounding formula to solve our given problem as:
, where
A = Final amount after t years,
P = Principal initially invested,
e = base of a natural logarithm,
r = Rate of interest in decimal form.
Upon substituting our given values in above formula, we will get:
Upon rounding to nearest cent, we will get:
Therefore, an amount of $7499.82 will be in account after 2 years.
The Gestalt principle of proximity states that objects and shapes form groups if they are close to one another. The shapes, sizes, and objects do not matter in this case even when there are visible differences. The law shows that smaller elements come together in a composition.
