If the probability of winning a slot machine is 5% and you are going to play 500 pulls. Using a normal approximation. What’s the probability that you win less than 40?
Answers
Answer:
0.9986 = 99.86% probability that you win less than 40
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Normal probability distribution
Problems of normally distributed distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].
The probability of winning a slot machine is 5% and you are going to play 500 pulls.
This means that [tex]p = 0.05, n = 500[/tex]
Mean and Standard deviation:
[tex]\mu = E(X) = np = 500*0.05 = 25[/tex]
[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{500*0.05*0.95} = 4.8734[/tex]
What’s the probability that you win less than 40?
Using continuity correction, this is P(X < 40 - 0.5) = P(X < 39.5), which is the pvalue of Z when X = 39.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{39.5 - 25}{4.8734}[/tex]
[tex]Z = 2.98[/tex]
[tex]Z = 2.98[/tex] has a pvalue of 0.9986
0.9986 = 99.86% probability that you win less than 40

When solving a system of equations algebraically, which statement results in no solution?
Answers
Answer:
all of these
0 does not equal 1
4 does not equal 7
2 does not equal -2
-3 does not equal 3
All of the given equations have no solution.
What are system of equations in mathematics?A system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables. They are of the form -
ax + by + c = 0
dx + ey + f = 0
We have the given system of linear equations that has no solutions.
For no solutions, the final equation should be of the form -
α = β
where [α] and [β] are constant integers.
So all the equations result in no solution.
Therefore, all of the given equations have no solution.

Ivy deposited some money into a savings account that earns 1%
annual simple interest. At the end of 5 years, she earned $32.50 in
interest. How much money did she put into the account initially?
Round to the nearest dollar.
Answers
Answer:
Ivy initially put $ 650 in the account.
Step-by-step explanation:
Given that Ivy deposited some money into a savings account that earns 1% annual simple interest, and at the end of 5 years, she earned $ 32.50 in interest, to determine how much money did she put into the account initially, the following calculation must be performed:
32.50 / 5 = 6.5
1 = 6.5
100 = X
100 x 6.5 = X
650 = X
Therefore, Ivy initially put $ 650 in the account.

The explanation is that the the supplementary angle to 80 is 100 since a straight line has an angle of 180, now the 100 degree angle is congruent to the angle x + 25 which means that x + 25 is equal to 100 so x is 75
so its X + 25 = 100
X = 100 - 25
X = 75

full before the five month deferment ends, the finance charge with an APR of 19.8% is applied each month going
back to the first month. How much would it cost Jackson in finance charges if he misses the 5-month deadline?
Answers
Answer:
If Jackson misses the 5-month deadline, it will cost him $429 in finance charges.
Step-by-step explanation:
Since Jackson purchased $ 5,200 worth of electronic equipment from BetterBuy on their deferred payment plan, and the plan allows the customer to make no down payment and no payment at all for five months, while if the entire amount is paid in full before the five month deferment ends, the finance charge with an APR of 19.8% is applied each month going back to the first month, to determine how much would it cost Jackson in finance charges if he misses the 5-month deadline the following calculation should be performed:
5,200 x (1 + (0.198 / 12 x 5)) = X
5,200 x (1 + (0.0165 x 5)) = X
5,200 x (1 + 0.0825) = X
5,200 x 1.0825 = X
5.629 = X
5,629 - 5,200 = 429
Therefore, if Jackson misses the 5-month deadline, it will cost him $429 in finance charges.
Gordon is trying to save up $2000 for a new saxophone he makes 12.50 per hour at his job at the coffee shop but he needs to set aside half of his hourly wage to pay his regular bills How many 40-hour weeks will he need to work before he can afford the saxophone?
A. 320 Weeks
B. 40 Weeks
C. 8 Weeks
D. 6.25 Weeks
Answers
Answer:
he will need to work 8 40-hour weeks.
Explanation:
since gordon has to set aside half of his wage to pay his bills, he can only save $12.50 ÷ 2 = $6.25 for the saxophone.
we can find how much money gordon saves from a 40-hour week by multiplying this by 40: $6.25 × 40 = $250.
now, divide the total amount of money he has to save by the amount he saves each week: $2000 ÷ $250 = 8.
he will need to work 8 40-hour weeks before he can afford the saxophone.
