Answer:
A
Step-by-step explanation:
6 friends
Mean - 10
Median - 9.5
Range - 14
3 friends watched 12, 13, and 18 movies.
Let's find the sum, this will help us find the total number of movies the other 3 friends watched.
12 + 13 + 18 = 43
The mean is all their movies added toether, divided by the number of friends.
m = number of movies the other friends watched.
(43 + m) / 6 = 10 Multiply each side by 6
43 + m = 10 * 6
43 + m = 60 Subtract 43 from each side
m = 60 - 43
m = 17
So we know the total movies the other friends watched is 3.
A. 4+6+7 = 17
B. 4+4+7 = 15
C. 5+8+9 = 22
D. 2+3+5 = 10
We know the answer is A.
We can check it by looking at the Median, the median is the middle number, if there are an even number of samples, you add the 2 middle numbers together and divide by 2.
4, 6, 7, 12, 13, 18
So 7+12 = 19
19/2 = 9.5
So we know for sure A is correct!
Answer:
x >8
Step-by-step explanation:
The correct answer is: "The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35."
Step-by-step explanation:
When numbers are considered, their position or place value matters a lot.
When a decimal number is written, moving left from the decimal point the place value increases ten times and while moving to the right the place value decreases 10 times.
Given two numbers are:
50.8 and 18.35
In order to compare the 5 in both numbers we have to find the place value of 55 in both numbers.
So,
<u>In 50.8:</u>
The place value of 5 in 50.8 is: 50
<u>In 18.35:</u>
The place value of 5 will be: 5/100
To compare the values, we will divide the larger place value by smaller place value

Hence,
The correct answer is: "The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35."
