Which of the following prefixes is best for measuring large quantities like the mass of a person?milli
kilo
deci
deca

Answers

Kilo, for kilogram is the best to use for easuring the mass of a person. 1 Kilogram (Kg) = 1000 grams. For example, I have 60 kilograms (132.27 pounds).

Mili is used for very small quantities (Mili = 1/1000 grams). Deci = 1/10 grams and deca 10 kilograms = 10.000 grams. Good luck !

The metric unit for weight is kilo.

you want to determine how many students consider math to be their favorite subject. you randomly survey 75 students. 33 students consider math their favorite subject and 42 do not. you conclude 40% of students at your school consider math to be their favorite subject. Is that valid?

Answers

No, is not valid.
33 is 44% of 75
33 ÷ 75 = 0.44
0.44 = 44%

A radar gun measured the speed of a baseball at 103 miles per hour. If the baseball was actually going 102.8 miles per hour, what was the percent error in this measurement?

Answers

Answer:

The percent error in this measurement is 0.194%.

Step-by-step explanation:

Given : A radar gun measured the speed of a baseball at 103 miles per hour. If the baseball was actually going 102.8 miles per hour.

To find : What was the percent error in this measurement?

Solution :

The actual speed is 103 miles per hour.

The estimated speed is 102.8 miles per hour.

The percentage is given by,

$\text{Percentage}=\frac{\text{Actual-Estimated}}{\text{Actual}}* 100$

$\text{Percentage}=(103-102.8)/(102.8)* 100$

$\text{Percentage}=(0.2)/(102.8)* 100$

$\text{Percentage}=0.194\%$

Therefore, the percent error in this measurement is 0.194%.

Answer:

0.924

Step-by-step explanation:

Hope this helps you and have a great day

Maria and Jeff collect data on the number of cars that pass through an intersection every Monday morning for 2 months. They record the findings as 78, 158, 63, 71, 56, 67, 75, and 64. They each use different methods to summarize the typical number of cars that pass through the intersection at the specified time and compare their findings. Jeff says that, on average, 79 cars pass through the intersection each Monday morning. Maria disagrees and says that the mean should not be used and uses the median instead to describe the typical number of cars that passes through the intersection on any given Monday morning.A) What is the median value of the data?

Answers

56, 63, 64, 67, 71, 75, 78, 79, 158 (putting numbers in least to greatest makes this easier) so what you would do to find the median is remove the first and last number until you have one number remaining.
Therefore the answer should be 71

How do you find the volume of a cylinder?? Step by step by step

Answers

1). Recall the formula for the volume of a cylinder:

Volume = (pi) x (radius of the round end)² x (length or height) .

2). Gather together the number you'll use for pi, the radius of the
cylinder's round end, and its length or height. Make sure that the
radius of the round end and the length or height are in the same units.
If they're not, then convert something so that they are.

3). Write each number into its place in the formula.

4). Perform the indicated operations. The final number is the
volume of your cylinder.

the formula is $\pi r^2h$ r= radius
h= height
you square the radius and then multiply by the $\pi$ and then the height
