The teacher asked 4 students to measure 4 different objects. The table shown represents their measurements. Which student had the largest percent error?

Answers

Answer 1

Answer:

Answer:

Student #4

Step-by-step explanation:

The formula for percentage error is given below. We will use this formula for all the four students and figure out whose error is the most.

Percentage Error = $|(MeasuredValue-ActualValue)/(ActualValue)|*100$

For student 1:

% Error = $|(49-50)/(50)|*100\n=|-0.02|*100\n=(0.02)(100)\n=2$

For student 2:

% Error = $|(25.5-25)/(25)|*100\n=|0.02|*100\n=(0.02)(100)\n=2$

For student 3:

% Error = $|(7.5-8)/(8)|*100\n=|-0.0625|*100\n=(0.0625)(100)\n=6.25$

For student 4:

% Error = $|(2.1-1.6)/(1.6)|*100\n=|0.3125|*100\n=(0.3125)(100)\n=31.25$

Clearly, 31.25% error of student #4 is the highest.

Answer 2

Answer: the correct answer is student four because it was off the most

Math Answers .if you take a test with 1 0questions and got 7 of them right,what decimal part would that be? what decimal part did you get wrong?? explain

Answers

right decimal percentage: If i take a test with 10 question and i got 7 of then right the decimal would be 0.7 in percent it would be 70%. That i your answer. (this is how much you got right.)

wrong decimal percentage: the wrong decimal percentage would be 0.3 because divide 7 by 10 and you get 0.7 and out of 10 would be 0.3, there is your answer.

I got .7 or .70 correct. Because 7/10=.70. I got .3 or .30 wrong because .70 is 70 out of 100. 100-70=30

What is the greatest common factor of 9 and 11

Answers

ANSWER:

The Greatest common factor (G.C.D) of 9 and 11 is 1

SOLUTION:

Greatest common factor (G.C.D) is the highest number which is factor for both the given numbers.

Here the numbers are 9 and 11.

We can find the Greatest common factor (G.C.D) of 9 and 11 using prime factorization method.

In prime factorization method, each number is written as the multiple of their prime factors, after that, on comparison we can find the Greatest common factor (G.C.D).

The prime factorization of 9 = $3 * 3 * 1=1 * 3^(2)$

The prime factorization of 11 = $11 * 1 = 1 * 11$

We can observe that, greatest common factor for both 9 and 11 is 1.

Hence Greatest common factor (G.C.D) of 9 and 11 is 1

The GCF of 9 and 11 is 1

First ten nonzero multiples of 2, 5, 6, 11, 20, 60

Answers

That depends on where you start, and in which direction you proceed.

If you start at zero and proceed in the positive direction, then you
encounter them as follows:

First ten non-zero multiples of 2 :
2, 4, 6, 8, 10, 12, 14, 16, 18, 20

First ten non-zero multiples of 5 :
5, 10, 15, 20, 25, 30, 35, 40, 45, 50

First ten non-zero multiples of 6 :
6, 12, 18, 24, 30, 36, 42, 48, 54, 60

First ten non-zero multiples of 11 :
11, 22, 33, 44, 55, 66, 77, 88, 99, 110

First ten non-zero multiples of 20 :
20, 40, 60, 80, 100, 120, 140, 160, 180, 200

First ten non-zero multiples of 60 :
60, 120, 180, 240, 300, 360, 420, 480, 540, 600

The correct answers are:

2, 4, 5, 8, 10, 12, 14, 16, 18, 20

60, 120, 180, 240, 300, 360, 420, 480, 540, 600

Explanation:

When finding the first non-zero multiples of a number, we count up by that number. For the twos, we keep adding 2 until we get the first ten terms. We follow a similar process for 5, adding 5 each time until we get the first ten terms.
