Answer:
- <u>4</u>
- <u>30 students</u>
- <u>8.1</u>
Step-by-step explanation:
Range of data :
- Maximum value - Minimum value
- 10 - 6
- <u>4</u>
Students in the group :
- Sum of frequencies
- 5 + 4 + 7 + 10 + 4
- 9 + 7 + 10 + 4
- 16 + 10 + 4
- 26 + 4
- <u>30 students</u>
Mean mark :
- 6(5) + 7(4) + 8(7) + 9(10) + 10(4) / 30
- 30 + 28 + 56 + 90 + 40
- 160 + 84 / 30
- 244/30
- <u>8.1</u>
Answer:
To find the absolute value of a number Find the distance from number to zero on a number line . The absolute value of a number is always Positive or zero .
Step-by-step explanation:
By taking a look at 1.64, you can already tell the 1 will be the whole number in the fraction. So let's focus on .64.
0.64 is in the hundredths place value, so the denominator will be 100. The unsimplified fraction would be 1 64/100.
To put this in simplest form we must divide 64 and 100. Let's start off with 2.
64/2 = 32
100/2 = 50
Let's continue until we can not divide by 2 anymore.
32/2=16
50/2 = 25
We can no longer divide by 2, howver there is not other number we can divide by both 16 and 25 evenly.
The answer in simplest form is 1 16/25

Defining variables
let n1 be the first number
n2 be the 2nd number
add them together, you get 218
n1+n2 =218
n1 is 47 less than n2
n1=n2-47
do some substitution
n2-47 +n2 = 218
solve for n2
then use n2 to figure out n1
