1. Think of two things that you can measure. Give one that requires high precision, or a low level of uncertainty. Give another that can have lower precision, or a higher level of uncertainty.
2. Explain why you made your choices. Why does one measurement need to be more precise than the other
1. We can measure the following two things:
(i) a person's height
(ii) the velocity required to reach Mars.
2. Everything involving a rocket launch needs to be extremely precise; otherwise, it could result in tragedy. However, anything involving a person's height won't result in disaster.
This can be solved using the concept of precision and uncertainty concept.
What is precision and uncertainty?The accuracy of a material or substance is the distance or degree to which two or more measurements are near to one another. Every time a measurement is performed, a new result is obtained that falls within the uncertainty interval that surrounds the measured value.
1. We don't need to be very precise because we can measure a person's height with a modest degree of accuracy. The person hearing would get a notion of their height if we said, "That individual is roughly 5 feet tall."
On the other hand, if we estimate the rocket speed to Mars incorrectly, it would lead to tragedy in the future, hence we require great precision. In order to ensure that we strike the necessary objective in space, we apply intricate mathematics.
2. Like we stated in problem 1, everything involving space travel needs extreme accuracy. The spaceship might crash and calamity could ensue if our estimates are incorrect. Engineers utilized the incorrect settings in the one instance where anything went wrong, causing the Mars lander to smash into the planet rather than securely land there.
Due to the enormous expense of these space exploration missions, it is imperative to obtain as many exact and accurate values as possible. Now, details like a person's height don't necessarily need to be accurate because we can just guesstimate a person's height depending on who we're speaking to.

Answer:
56
Step-by-step explanation:
8C5 = 56
Answer:
8C5 = 56
Step-by-step explanation:
The formula for nCk is ...
nCk = n!/(k!(n-k)!)
Then the value of 8C5 is ...
8!/(5!(8-5)!) = 8·7·6/(3·2·1) = 8·7
8C5 = 56

The larger of the denominator factorials will cancel most of the factors of the numerator. The remaining denominator factors can be factored from the remaining numerator values to simplify the problem of doing the math by hand. Most graphing calculators and all spreadsheets can compute this function for you.

The sum of 75 and 45 is divided by 5 and the difference of quotient and 10 is multiplied by 2. (Ans: 28) (Hint:- Make mathematical expressions, then simplify) (Please solve my question)
Answer:
28
Step-by-step explanation:
(((75+45) ÷5) - 10 )2 -> first add 75 and 45
((120 ÷ 5) - 10)2 -> Divide 120 by 5
(24 - 10)2 -> Subtract 24 by 10
(14)2 - > 28

Teresa works as a tutor for 7 an hour and as a waitress for 12 an hour. This month, she worked a combined total of 97 hours at her two jobs.
Let 't' be the number of hours Teresa worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month.
Answer:
12t + 7(96 - t) = 12t + 672 - 7t = 5t + 672
Step-by-step explanation:
96-t number of hours as a waitress
Let t number of hours as a tutor
12t + 7(96 - t) = 12t + 672 - 7t = 5t + 672

Diagram not drawn to scale
80°
A straight line joining the midpoints of two of its sides is drawn.
Answer:
130 degrees
Step-by-step explanation:
The right top triangle is isosceles, so the supplementary angle of angle α is (180 - 80)/2 = 50 degrees.
Therefore, α = 180 - 50 = 130 degrees.
Three workers are digging a ditch. They take turns working, and every one of them works for as long as it would take the other two to dig half of the ditch. They finished digging the ditch working in this manner. How many times faster would the three workers have finished digging the ditch if they had all been working at the same time?
The work would be finished 2.25 times faster if they had been doing the work at the same time.
Rate of doing workAssumption;
Provided each one of the workers works for an hour which is equivalent to the time it takes to finish half of the ditch.In essence, the total time required to finish the ditch by 2 workers is; 2 hours.
Hence, for 3 workers working simultaneously, the time required is 1hour 20 minutes. = 80 minutesHowever, since they took 1 hour turns on the job, it follows that; The total time used is;
Total time = 3 × 1hr = 3 hours = 180 hoursHence they could have finished the work in;
R = 180/80 times faster = 2.25 times faster.Read more on rate of work;

Answer:
20 years
Step-by-step explanation:
when the boy is 8 and half his sisters age his sister is 16
four years later the boy will be twelve, so if his sister was 16 four years later she will be 20
Answer:
20 years old
Step-by-step explanation:
Let n represent the age of the boy's sister then...
[tex]8=\frac{1}{2}n[/tex]
Multiply both sides by 2
[tex]n=16[/tex]
When the boy is 12, it will be 4 years from when he is 8 therefore...

in order for students to have a club at school they need a minimum of 26 students. If there are 19
students signed up for the club, how many more students does the club need?
What are the solutions? Select the correct choice below and fill in the answer box to complete your
choice
Answer:
7 more students.Basic subtraction:
needed students: minimum required students - students signed up
needed students: 26 - 19
needed students: 7 students, the club needs.
Solution:
We know that the inequality form is x ≥ 26. If we subtract the number of students required by the number of students joined, we will obtain the required students to start the club.
=> Required students - Students joined = Students remained to join=> 26 - 19 = Students remained to join=> 7 studentsHence, the club needs 7 more students to have a club.

Talks 1hr month 9
Talks 1 1/2 hrs 10 and. 11th month

Line plots are used to express variables using markers
The total phone call for eight months is [tex]10\frac 34[/tex] hours
How to determine the total phone callsFrom the line plot, we have the following summation
[tex]Total = 1hr + 1\frac 12 hr * 2 + \frac 34 hr[/tex]
When the total hours of phone call for the 8th month is added, the summation equation becomes
[tex]Total = 1hr + 1\frac 12 hr * 2+ \frac 34 hr + 6 hr[/tex]
Add the expressions
[tex]Total = 10\frac 34[/tex]
Hence, the total phone call for eight months is [tex]10\frac 34[/tex] hours
