What is the experimental probability of rolling the given result?
a.
0.88
c.
0.56
b.
0.34
d.
0.44
Answers
==========================================================
Explanation:
Add up all the frequencies that correspond to outcomes that are more than 3
So we'll add up the last three frequencies (since they correspond to outcomes of 4, 5 and 6 all of which are greater than 3) to get 20+30+38 = 88
We have 88 occurrences of rolling either a 4, a 5 or a 6. This is out of 200 rolls total.
The empirical (or experimental) probability of getting more than 3 on the die is 88/200 = 0.44

[tex]\textsf{C.} \quad C = \$10 + \$5h[/tex]
Step-by-step explanation:
Given information:
Admission fee to the Park = $10Fee for Sledding = $5 per hourGiven variables:
C = total cost (in dollars)h = time (in hours)The Park admission fee of $10 is independent of the fee charged per hour per sport. Therefore, it is represented by a constant in the equation.
The fee per hour of sledding is dependent on the number of hours spent. Therefore, it is represented by the cost of the specific sport multiplied by the given variable for time (h).
Therefore the equation that represents the cost of sledding per hour is:
C = $10 + $5h
[tex]\huge \boxed{\sf C}[/tex]
Each hour costs 5 dollars for sledding and an extra fee of 10 dollars.
[tex]\sf C = 5h + 10[/tex]
An equation contains variables and integers.
C and h are variables which means the value changes.
5 and 10 are integers.

Step-by-step explanation:
30 + 10 (x - 20) = 5
you cant add the numbers in the parenthesis so you add the first two numbers and distribute.

Determine the value for the trigonometric expression. Give an exact answer in degrees. Hint: Consider only the principal value of an inverse trigonometric function. Cos(Ta * n ^ - 1 - (sqrt(3))/3)
Answers
Answer:
√3/2
Step-by-step explanation:
We are to find the exact value of the expression below
Cos(Tan^- 1 - (sqrt(3))/3)
Evaluate the one in bracket first
Tan^-1√3/3 = 30°
Cos(Tan^- 1 (sqrt(3))/3) = Cos30°
Now find cos30°
cos30° = √3/2
Hence the value for the trigonometric expression is √3/2

Trey wants to take a European vacation in 3 years. He estimates the cost to be $10,000.
About how much must he save monthly in an account that pays 4% interest, compounded monthly, to have enough money for the vacation?
Answers
Answer:
Monthly deposit= $262.062
Step-by-step explanation:
Giving the following information:
Future value= $10,000
Number of periods= 12*3= 36 months
Interest rate= 0.04/12= 0.0033
To calculate the monthly deposit, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (10,000*0.0033) / [(1.0033^36) - 1]
A= $262.062

Addison made fancy orange costume decorations for each of the 9 dancers in her year-end dance performance. She cut 7 1/5 yards of ribbon into equal pieces to make the decorations. How long was each piece of ribbon?
Answers
Answer:
0.8 yards or 28.8 inches
Step-by-step explanation:
I always turn fractions into decimals because it is easier to figure it out and simpler.
So 1/5 would be 2/10 because you multiply the whole thing by 2 to make the denominator 10 so you can turn it into a decimal.
So the decimal is 0.2
You would divide 7.2 by 9 to get 0.8 yards which is 28.8 inches.

A trade school would like to measure the long-term success of its graduates after they leave the school, and emails a survey requesting information from graduates about their work experience. One question asks graduates if they are currently employed in the field they studied in school, while another asks them to share their annual salary. What type of bias is most likely to be present in the survey results?
This is response bias because some graduates may not provide accurate information.
This is question wording bias because many graduates may misunderstand the questions asked.
This is voluntary response bias because graduates may choose to be part of the sample.
This is nonresponse bias because many graduates may choose not to respond to the email survey.
Answers
Answer:c will be the answer YW!
Step-by-step explanation:
This is voluntary response bias because graduates may choose to be part of the sample that is most likely to be present in the survey results. Thus option C is correct.
What is a survey?A survey is a set of inquiries designed to elicit specified data from a certain population. Surveys can be carried out via the radio, by postal, online, at town squares, and even in shopping centers.
When elements are personality volunteers who are degree holders, volunteered response bias emerges. Voters determine whether or not they will participate in the sample once the research involved a group of people to do so.
Graduating students may select to be a part of the population that is the most likely to appear in the survey results, resulting in voluntary response bias. Therefore, option C is the correct option.

Answer:

Step-by-step explanation:
Given the equation for the Law of Cosines, we can rewrite the equation to solve for "c" directly:
[tex]c^2=a^2+b^2-2ab(cosC)\\c=\sqrt{a^2+b^2-2ab(cosC)}\\c=\sqrt{7^2+8^2-2(7)(8)(cos32)}\\c=\sqrt{49+64-2(56)(cos32)}\\c=\sqrt{113-112(cos32)}\\c=\sqrt{113-94.98138677}\\c=\sqrt{18.01861323}\\c=4.244833711\\c=4.2[/tex]
