Answer:
485.24 miles per hour
Step-by-step explanation:
The required average speed of the flight is 485.25 miles per hour.
Given that,
Key west, Florida to Seattle, Washington is 3,518 miles. If it takes 7 hours and 15 minutes to fly there, what is the average speed is to be determined?
The average of the values is the ratio of the total sum of values to the number of values.
What is speed?Speed is defined as when an object is subjected to move, the distance covered by the object in a certain time interval is the speed of that object.
Total distance to fly = 3,518 miles
Total time = 7 hours 15 minutes = 7 + 15/60
= 7.25 hour
Speed = distance / time
= 3, 518 / 7.25
= 485.25 miles / hours,
Thus, the required average speed of the flight is 485.25 miles per hour.

In a survey, 205 people indicated they prefer cats, 160 indicated they prefer dots, and 40 indicated they don’t enjoy either pet. Find the probability that if a person is chosen at random, they prefer cats
Answer: probability = 0.506
Step-by-step explanation:
The data we have is:
Total people: 205 + 160 + 40 = 405
prefer cats: 205
prefer dogs: 160
neither: 40
The probability that a person chosen at random prefers cats is equal to the number of people that prefer cats divided the total number of people:

Stats A simple random sample of FICO scores is listed below. The mean FICO score is reported to be 678. Assuming that the standard deviation of all FICO scores is known to be 58.3, use a 0.01 significance level to test the claim that these sample FICO scores come from a population with a mean equal to 678. DATA: 714, 751, 664, 789, 818 , 779, 698, 836, 753, 834, 693, 802.
Step-by-step explanation:
The sample mean is:
(714+751+664+789+818+779+698+836+753+834+693+802) / 12
≈ 760.9
At 0.01 significance level and 11 degrees of freedom, the critical value is t = 3.106.
The standard error is 58.3 / √12 = 16.8.
The confidence interval is:
760.9 ± 3.106 × 16.8
(708.6, 813.2)
678 is outside of the confidence interval, so we can conclude with 99% confidence that the sample does not come from a population with a mean of 678.
To test the claim that the sample FICO scores come from a population with a mean equal to 678, we can use a one-sample t-test.
What is t-test?A t-test is a statistical test used to determine if there is a significant difference between the means of two groups.
It is often used when the sample size is small or when the population standard deviation is unknown.
To test the claim that the sample FICO scores come from a population with a mean equal to 678, we can use a one-sample t-test.
First, we need to calculate the t-value using the following formula:
t = (x - μ) / (s / sqrt(n))
We are given that x = 678, μ = 678, s = 58.3, and n = 12. Substituting these values into the formula, we get:
t = (678 - 678) / (58.3 / sqrt(12))
t = 0
Next, we need to find the critical t-value using a t-distribution table or calculator with 11 degrees of freedom (df = n - 1) and a 0.01 significance level. The critical t-value is 3.106.
Since the calculated t-value of 0 is less than the critical t-value of 3.106, we fail to reject the null hypothesis that the sample FICO scores come from a population with a mean equal to 678.
Thus, in other words, there is not enough evidence to support the claim that the sample FICO scores have a different mean than the population mean of 678.

Answer:
A. The mean mileage per gallon is _____ 28.99__
A. The median mileage per gallon is _____27.905_____
B. The mode does not exist.
Step-by-step explanation:
Mean= Sum of values/ No of Values
Mean = 24.2 + 22.2+ 37.8+ 22.7 + 35.4 +31.61/ 6
Mean = 173.91/6= 28.985 ≅ 28.99
The median is the middle value of an ordered data which divides the data into two equal halves. For an even data the median is the average of n/2 and n+1/2 value where n is the number of values.
Rearranging the above data
22.2 , 22.7 , 24.2 , 31.61 , 35.4, 37.8
Third and fourth values are =24.2 + 31.61 = 55.81
Average of third and fourth values is = 55.81/2= 27.905
Mode is the values which is occurs repeatedly.
In this data there is no mode.

Complete Question
Based on past experience, it is predicted that 31% of registered voters in Oklahoma will vote in the next primary. The 31% would be considered an example of:
A) Qualitative data
B) Descriptive statistics
C) A sample
D) Inferential statistics
Solution
Taking the options one at a time.
- Qualitative data is a dataset where the members of the dataset are grouped or represented according to some categorical condition or property. It is also called categorical data. It is normally non-numerical in nature. This is obviously not the correct answer.
- Descriptive Statistics are brief or summary statistics that summarize a given data set. Descriptive statistics are broken down into measures of central tendency and measures of dispersion or variability (the spread of the distribution about the mean). The 31% is a prediction using past datasets, it isn't a descriptive statistic to summarize all that is in the current dataset.
- A sample is a dataset that consists of variables picked from the population distribution. It is a smaller set of variables usually extracted from the population. This is also not the answer.
Inferential Statistics uses results from the past datasets or dataset using some other condition to obtain a predicted statistic for a current dataset or the dataset given current conditions.
From the question, the results from the old dataset (based on past experiences), is used to predict some statistic (percentage of registered voters in Oklahoma who will vote in the next primary). It is evident that this is the answer; 31% prediction for registered voters in Oklahoma will vote in the next primary, was made using past experience. Inferential Statistic.

Step-by-step explanation:
Probability and odds:
Suppose we have a probability p.
The odds are of: 10p to 10

If a hypothesis is not rejected at the 0.10 level of significance, it: a. may be rejected at the 0.05 level. b. must be rejected at the 0.025 level. c. must be rejected at the 0.05 level. d. will not be rejected at the 0.05 level.
Answer:
Option D - Will not be rejected at the 0.05 level.
Step-by-step explanation:
The significance level, which is denoted as "α", is a measure of the strength of the evidence that must be present in a sample before we can reject the null hypothesis and conclude that the effect is statistically significant. Now, this significance level must be determined before conducting an experiment.
Now, in the context of this question, the significance level is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 means a 5% risk of concluding that a difference exists when there is no actual difference. Now, lower significance levels will indicate that we require stronger evidence before we can reject the null hypothesis.
Thus, if we don't reject at α = 0.1,we obviously will not reject at higher values.
Thus, looking at the options, we will not reject at 0.05 significance level.

The sample space for the event of rolling two dice is presented below
[tex](1,1), (2,1), (3,1), (4,1), (5,1), (6,1)\\(1,2), (2,2), (3,2), (4,2), (5,2), (6,2)\\(1,3), (2,3), (3,3), (4,3), (5,3), (6,3)\\(1,4), (2,4), (3,4), (4,4), (5,4), (6,4)\\(1,5), (2,5), (3,5), (4,5), (5,5), (6,5)\\(1,6), (2,6), (3,6), (4,6), (5,6), (6,6)[/tex]
Total number of outcomes =36
The event of rolling a 5 or a 6 are:
[tex](5,1), (6,1)\\ (5,2), (6,2)\\( (5,3), (6,3)\\ (5,4), (6,4)\\(1,5), (2,5), (3,5), (4,5), (5,5), (6,5)\\(1,6), (2,6), (3,6), (4,6), (5,6), (6,6)[/tex]
Number of outcomes =20
Therefore:
P(rolling a 5 or a 6) [tex]=\dfrac{20}{36}[/tex]
The probability distribution of this event is given as follows.
[tex]\left|\begin{array}{c|c|c}$Amount Won(x)&-\$1&\$2\\&\\P(x)&\dfrac{16}{36}&\dfrac{20}{36}\end{array}\right|[/tex]
First, we determine the expected Value of this event.
Expected Value
[tex]=(-\$1\times \frac{16}{36})+ (\$2\times \frac{20}{36})\\=\$0.67[/tex]
Therefore, if the game is played 100 times,
Expected Profit =$0.67 X 100 =$67
If you play the game 100 times, you can expect to win $67.
(b)
Probability of Winning [tex]=\dfrac{20}{36}[/tex]
If the game is played 100 times
Number of times expected to win
[tex]=\dfrac{20}{36} \times 100\\=56$ times[/tex]
Therefore, number of times expected to loose
= 100-56
=44 times
Find the length and width of a rectangle that has the given perimeter and a maximum area. Perimeter: 116 meters
Answer:
Length = 29 m

Answer: A positive correlation
Step-by-step explanation:
Correlation tells the relation between two variables.
A positive correlation exists when two variables are proportional to each other.A negative correlation exists when two variables are inversely proportional to each other.As we know that the amount of weight you gain depends upon the number of calories you eat.
That means the amount of weight is directly proportional to the number of calories you eat ( if not burn by exercise).
That means there is a positive correlation.
