A binomial probability experiment is conducted with the given parameters. Compute the probability of x successes in the n independent trials of the experiment.
nequals=7
pequals=0.65 xequals=6
(Do not round until the final answer. Then round to four decimal places as needed.)
The probability of 6 successes in 7 independent trials with a probability of success 0.65 is 0.3052.
Using the binomial probability formula, the probability of x successes in n independent trials with a probability of success p can be calculated as:
P(x) = (n choose x) * p^x * (1-p)^(n-x)
where "n choose x" represents the number of ways to choose x items from a set of n items, and is calculated as:
(n choose x) = n! / (x! * (n-x)!)
So, for the given parameters nequals=7, pequals=0.65, xequals=6, we have:
P(6) = (7 choose 6) * 0.65^6 * (1-0.65)^(7-6)
= 7 * 0.65^6 * 0.35^1
= 0.3052
Therefore, the probability of 6 successes in 7 independent trials with a probability of success 0.65 is 0.3052.

A random sample of 130 students is chosen from a population of 4,500 students. The mean IQ in the sample is 120, with a standard deviation of 5. Using a margin of error of 1.13%, what is the 99% confidence interval for the students' mean IQ score?
Answer:
\(120-2.614\frac{5}{\sqrt{130}}=118.85\)
\(120+2.614\frac{5}{\sqrt{130}}=121.15\)
Step-by-step explanation:
Information given
\(\bar X= 120\) represent the sample mean
\(\mu\) population mean (variable of interest)
s=5 represent the sample standard deviation
n=130 represent the sample size
For this case we can't set a margin of error just with a % since they not specify 1.13% respect to something for this case we can omit this value
Confidence interval
The confidence interval for the mean is given by the following formula:
\(\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}\) (1)
The degrees of freedom are given by:
\(df=n-1=130-1=129\)
The Confidence level is 0.99 or 99%, the significance would be \(\alpha=0.01\) and \(\alpha/2 =0.005\), and the critical value would be \(t_{\alpha/2}=2.614\)
And replacing we got:
\(120-2.614\frac{5}{\sqrt{130}}=118.85\)
\(120+2.614\frac{5}{\sqrt{130}}=121.15\)

the direction of air currents in the Northern and Southern Hemispheres
The option that describes the Coriolis effect is D. the direction of air currents in the Northern and Southern Hemispheres.
What is the Coriolis effect?The effect of the Earth's rotation on weather patterns and ocean currents is known as the Coriolis effect. Storms swirl clockwise in the Southern Hemisphere and counterclockwise in the Northern Hemisphere due to the Coriolis effect. Circulating air is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere as the Earth rotates on its axis. The Coriolis effect refers to this deflection.
The rotation of the Earth causes the Coriolis effect. Moving objects in the Northern Hemisphere tend to curve to the right of their intended paths; moving objects in the Southern Hemisphere tend to curve to the left of their intended paths. The Coriolis effect causes moving objects to accelerate or decelerate.
Therefore, based on the information given, it should be noted that the correct option is D.

Savannah buys a bag of cookies that contains 8 chocolate chip cookies, 9 peanut butter cookies, 7 sugar cookies and 6 oatmeal cookies. What is the probability that Savannah randomly selects a sugar cookie from the bag, eats it, then randomly selects a chocolate chip cookie? Express you answer as a reduced fraction.
total cookies first to find ratio values
8 + 9 + 7 + 6 = 30 total
first ratio is sugar cookie to total
7 / 30 chances
after eating the sugar cookie, the total reduces to 29
second ratio is the new total
8 / 29 chances.
potential bonus??
the odds of this happening in this exact order is both odds multiplied.
so (7/30) × (6/29) = 7 / 145 chances she completes this in the exact order stated.
A family buys 5 airline tickets online. The family buys travel insurance that costs $18 per ticket. The total cost is $885. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket.
Answer:
One ticket is $153
Step-by-step explanation:
x = The price of a ticket
855=5x+18(5)
855=5x+90
765=5x
153=x
Answer:
x = $159
Step-by-step explanation:
5 tickets are bought, the price of them is unknown?
1 ticket per $18 travel insurance
5 tickets = 18 × 5
insurance per 5 tickets = $90
the equation:
let X represent the number of tickets.
5x + 90 = 885. the total cost of insurance and tickets = 885
we solve the equation.
5x=885 - 90
5x= 795. divide by 5 into both sides.
x= $159. which is the price of one ticket.

at a certain university in the u.s., all phone numbers are 7-digits long and start with either 824 or 825. 1) how many different phone numbers are possible?
There are 20,000 different phone numbers possible that is 7-digits long and start with either 824 or 825.
Fundamental Principle of Counting, also called the counting rule, is the method to count how many ways multiple independent events can occur.
Based on the given information, all phone numbers are 7-digits long and starts with either 824 or 825. Hence, the four last digits will be the combination of numbers from 0 to 9.
Thus, by Fundamental Principle of Counting, the number of possible outcomes is 20,000.
= (number of phone numbers starting with 824) + (number of phone numbers starting with 825)
= (10 x 10 x 10 x 10) + (10 x 10 x 10 x 10)

We want to determine whether or not there is a significant difference between the average salaries of the employees at the two companies. Compute the test statistic. b. Compute the p-value; and at a=.05, test the hypotheses. c. Which company, if either, appears to have the higher salary? Provide a 95% confidence interval for the difference between the population mean salary of employees for the two companies.
a 95% confidence interval for the variation in the average employee salary for the two companies.
a. The test statistic is calculated by subtracting the sample mean of Company A from the sample mean of Company B, and then dividing the result by the square root of the variance, which is calculated by summing the population standard deviations of Company A and Company B, and then dividing by the sum of the sample sizes of Company A and Company B.
Test statistic = (48 - 43) / √(12^2 + 10^2) / (72 + 50) = 0.766
b. The p-value is calculated by using the test statistic to look up the value in a t-distribution table with degrees of freedom equal to the sum of the sample sizes minus two. The p-value is 0.239.
At a=.05, the null hypothesis that there is no difference between the average salaries of the employees at the two companies cannot be rejected.
c. Company A appears to have the higher salary. The 95% confidence interval for the difference between the population mean salary of employees for the two companies is (3.073, 5.927).

What would be the complexity of the size() method for the linked implementation of a list, if there were no count variable?
If there were no count variable, the complexity of the size() method for the linked implementation of a list would be O(n).
How complicated is the size?
By evaluating the impacts of size rise and decrease, the link between size and complexity is examined. Size increase necessitates an increase in complexity, whereas size drop permits, and occasionally necessitates, a decrease in complexity.Since the linked list's length cannot be stored in a count variable, we must traverse the list from head to tail to get its size.
To obtain the size for n nodes, we will traverse all n nodes. As a result, the time complexity is O (n).

The new credit card balance on her credit card is $219 if no interest is added on balance.
What Is a Credit Card Balance?The total sum of money owing by a cardholder to their credit card company is known as their credit card balance. Balances fluctuate depending on when and how they are used; they rise when purchases are made and fall when payments are made by cardholders. Any sum that is left over at the end of the billing cycle is added to the bill for the following month and is subject to interest. The balances on a person's credit cards play a significant role in determining their credit score. Future lenders will evaluate them to assess the risk (and price) of extending further credit to their clients.
