What is probaility?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event
The expected value of any discrete variable X is calculate as:
E(X)=X1*P(X1)+X2*P(X3)+...+X3*P(X3)
Where X1, X2, ..., X3 are the values that the variable can take and P(X1), P(X2), ..., P(X3) are their probabilities.
In this case the variable X is the dollars that can win, so:
X1=$2,000
X2=$300
x3=$20
X4=$0
Then the probabilities can be calculate as:
[tex]P(X_1)=\dfrac{1}{600}\\\\\\P(X_2}=\dfrac{3}{600}\\\\\\P(X_3)=\dfrac{15}{600}\\\\\\P(X_4)=\dfrac{581}{600}[/tex]
Replacing the variables and probabilities on the equation of expected value we get:
[tex]E(X)=(2000\times \dfrac{1}{600})+(300\times \dfrac{3}{600})+(20\times \dfrac{15}{600})+(0\times \dfrac{581}{600})[/tex]
E(X)=$4
Additionally, the student bought a ticket by $5, so the expected profit can be calculate as:
Expected Profit = Expected Earnings - Cost = $4 - $5 = $-1
Finally, the expected value of the profit is $-1

large of a sample size is required=165
what is z value in statistics?The Z-value is a test statistic for Z-tests that measures the difference between an observed statistic and its hypothesized population parameter in units of the standard deviation
Using the formula:
large of a sample size is required=(Z∝[tex]I_{2}[/tex]/E)²* P(1-P)
According to the given data
E= margin of error= 5%=0.05
96% confident that your estimate is within 5% of the true population proportion,
Therefore, level of significance
∝=1-0.96
=0.04.
Z value for the 96% confident is 2.05, therefore, Z∝I2=2.05
Therefore, large of a sample size is required=(2.05/0.05)²* (0.11)(1-0.11)
=1681*0.0979

QUADRATIC FORMULA
11. The current World Record for the Track event Shot Put is 23.37 meters - meaning the Shot landed
23.37 meters from where it was launched (DO NOT USE THIS VALUE FOR THE EQUATION).
The path of the Shot thrown by an athlete during a track meet can be modeled by the Quadratic Equation
h(t) = -0.09c2 + 2t + 1.67 where he represents its height in meters and m represents the horizontal
distance in meters. How far did the Shot land from where it was thrown? Substitute 0 for h in your Equation
in order to find the horizontal distance from where this Shot was lauchedlaunched.
Answers
Answer:
23.028 meters
Step-by-step explanation:
We presume your quadratic equation is intended to be ...
h(m) = -0.09m² +2m +1.67
where h(m) is the height in meters, and m is the horizontal distance in meters. You want to find the positive value of m when h = 0.
__
The quadratic formula tells you the solution to ...
ax² +bx +c = 0
In your equation, a = -0.09, b = 2, c = 1.67, and the variable is m. The solutions given by the formula are ...
[tex]m=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-2\pm\sqrt{2^2-4(-0.09)(1.67)}}{2(-0.09)}\\\\=\dfrac{2\pm\sqrt{4+0.6012}}{0.18}\approx\{-0.806,23.028\}[/tex]
The shot landed about 23.028 meters from where it was thrown.
_____
Additional comment
The shot was launched at an angle of about 63.4° from the horizontal. Had a shallower angle been used with the same launch speed (about 16.5 m/s), the shot would have traveled farther. At about 45°, the distance might have been in excess of 29 meters.
