There are a lot of questions and work here, I can help you get started in the right direction.
On the left, you have the heights for Soil A. On the right, you have the height for Soil B. Looking at the overlap, there are a lot of heights in the 60's and 70's for both.
To calculate the mean, add up all the values and divide by the total.
For the MAD, you have to subtract each value from the mean. Then, take the absolute value of it. Finally, find the mean of those values.
The one with the higher MAD is more variable.
Answer:
1: equivalent
2: equivalent
3: not equivalent
Step-by-step explanation:
for 1 & 2, you just switch the terms, but for 3, the 6z is not negative in the first expression, but it is in the second.
Answer:
530.66
Step-by-step explanation:
The way we find the area of the circle we use the radius of the circle for this one it's 13cm squared * pi or 3.14
For this circle we do 3.14 * 13^2
First we have to square 13: 13^2 = 169
Then we multiply 169 by 3.14: 3.14 * 169 = 530.66
Then we do to the nearest hundredth which is the same as the previous answer: 530.66
(-5,9) because -6—1=-6+1 which equals -5 and 7—2=7+2 which equals 9
The answer is A, positive. As you can see all the dots are all moving upwards.
