Step-by-step explanation:
In a given amount of time, Jamie drove four times as far as Rhonda. Altogether they drove 125 miles. Find the number of miles driven by each.
Answer:
25
Step-by-step explanation:
Theres a ratio of 1:4
Where Jamie has driven 4 times as much as Rhonda
meaning that you can plug in values, 1:4=125
the 4 represents Jamie since she drove farther than rhonda
Rhonda drove 25 miles, and Jamie drove 100 miles
25(4)+25=124

Which trig ratio would you use to solve for the missing angle measure? 5 A) Cos! 26 26 B Cos-1 5 C) Sin 26 Sin? 26 5
Answer: Choice A) [tex]\cos^{-1} \frac{5}{26}[/tex]
You could also write [tex]\cos^{-1} \left(\frac{5}{26}\right)[/tex] which is the same as writing [tex]\arccos\left(\frac{5}{26}\right)[/tex]
Arccos stands for "arccosine", which is effectively the same as inverse sine. The notation [tex]\cos^{-1}[/tex] means inverse cosine.
We use the cosine rule because
cos(angle) = adjacent/hypotenuse.
isolating the angle leads to
angle = arccos(adjacent/hypotenuse)
We can think of arccosine as an operation to undo the cosine function. It's similar to how division is the opposite of multiplication.

If you buy a burger and fries at your favorite fast food restaurant:___________
A. then GDP will be higher, but consumption spending will be unchanged.
B. then both GDP and consumption spending will be higher.
C. then neither GDP nor consumption will be affected because you would have eaten at home had you not bought the meal at the restaurant.
D. then GDP will be unchanged, but consumption spending will be higher.
Answer:
A. then GDP will be higher, but consumption spending will be unchanged.
Step-by-step explanation:
GDP is the monetary value of all the finished goods and services produced within a country in a specific time period by the country's citizens and foreigners.
It is primarily used to assess the health of a country's economy and it is calculated by adding the following figures together:
personal consumption private investment government spending; and exports
The burger and fries are services provided by the restaurant, which added value to the economy by increasing the GDP.
However, the consumption spending will not be affected because you would have eaten at home had you not bought the meal at the restaurant.
Therefore, the correct option is A " then GDP will be higher, but consumption spending will be unchanged".

How many joules of gravitational potential energy are stored in an object that has a mass of 8.5 kilograms and is held 2 meters above the surface of earth?
Answer:
I believe the answer is 166.6 Joules or (if rounding to the nearest whole number) 167 Joules.
Step-by-step explanation:
Here is the formula to find the gravitational potential energy of an object:
U = m * g * h (potential energy equals mass times gravitational acceleration * the height)
The mass is 8.5 kilograms, the height is 2 meters, and Earth's gravitational acceleration is always, no matter the other values or earthly situations, 9.8 m/s.
Now we solve:
8.5 * 9.8 * 2 = 166.6 which is rounded to 167 Joules.

The following data are the daily number of minutes of smartphone use for a random sample of 8 students at your institution: 117, 156, 89, 72, 116, 125, 101, 100.
(a) Test the null hypothesis according to which the true mean is 100 min against the alternative that it is different than 100. Use a significance level of 5% (state the null and the alternative hypothesis, the test statistic and the conclusion). (10 points)
(b) Compute a 95% confidence interval for the true mean number of minutes per day a student uses his or her smartphone. Is your finding consistent with your answer in (a) (Explain why or why not)?
Step-by-step explanation:
Number of students = 8
Mean of sample = 876/8
= 109.5
We solve for standard deviation using formula:
S = √(Xi -barX)/n-1
S = 25.3264
A.
H0: u = 100
H1: u not equal to 100
T test = barX - u/s/√n
t = 109.5-100/(25.3264/√8)
= 9.5/8.9542
= 1.0609
Df = 8-1 = 7
P value = 0.953141 at 5% significance level. P-value > 0.05 so we fail to reject H0
Conclusion: insufficient evidence that mean = 100
B.
95% = bar x +-t*s/√n
t = 2.365 at 95% and df = 7
109.5 +- 2.365(25.3264/√8)
= 109.5 +- 2.365(8.9542)
= 109.5-21.1768, 109.5+21.1768
= (88.3232, 130.6768)
In conclusion true mean is in the confidence interval, so it is consistent.

A researcher studies differences in career goals between boys and girls in middle school. All of the students in the seventh grade schools in a particular county answer a list of questions. What type of study is this?
A. Experiment
B. Sample Survey
C. Observational Study
D. Random Trial
Explanation:
When asking/answering questions like this, a survey is involved. It could be multiple choice or fill in the blank. Multiple choice may be the best way because it's easier to compare data results when you have only a few options. It also gives the computer an easier time too.
We aren't conducting an experiment since the researcher is not directly affecting the people, and instead letting them answer the questions without intervention. Also, note how we don't have two groups of treatment vs control. This is another indication we don't have an experiment.
An observational study is not being done here either. Yes the researcher is observing the survey results, but s/he is not making notes on the individuals before the survey is conducted (ie before the questions are asked). An example of an observational study is having the researcher make a tally of students' hair color. The researcher simply looks at each student, marks the correct tally, and doesn't need to ask the student a question. So you can see that the interactive question/answer portion is not present in an observational study.
The phrasing "random trial" is not a study type. When you hear "random trial" in the news, maybe for a new drug being developed, the news report is implying heavily that an experimental study had been done. This is true with all drug trials. One group is the treatment group that gets the actual drug, while the control group gets a fake drug. The control group thinks they get the actual drug, which is important because if they knew it was fake, then it would invalidate the study. I recommend researching the placebo affect for more information. The two group's results are then computed to see if the drug did in fact cause a change in the subjects or not. You would see this if there's a significant difference between the treatment and control group. Anyway, the "random trial" is not a study type but rather an aspect of an experimental study. It's possible your teacher put this in here to throw off students.
