A method I use is to write them down... several times like handwriting
Answer:
Step-by-step explanation:
Distribute the -5 to x and -1
-5x+5=2x+15
Subtract 5 from 15
-5x= 2x +10
Subtract 2x away from -5x
7x= 10
Divide
X= - 1.428571429
Answer:
-0.2+7k
Step-by-step explanation:
Rearrange the equation so that it is 1.8-2+7k
1.8-2=-0.2
You can't add 7k because it doesn't have a common variable
-0.2+7k
2.5 feet is half of 5 feet meaning we know that 2.5 feet is gonna be equal to half of two inches. So we need the answer that gives us one. 2/2.5 = 0.8 and 0.8/5 = 0.4. This means the answer is not A as it is too small. 5/2.5 = 2 and 2/2 = 1 meaning that it must be b. Therefore it cannot be c cause its already b.
Answer:
Answer: D : Median, because there is 1 outlier that affects the center
Step-by-step explanation:
Mean and median terms are use to measure the central tendency in a data set.
Mean is the best measure of center if there is no outlier present in the data otherwise median is the best measure of center if there is outlier present because outliers effects the means value of a data but not the median value.
In the third period, there is an outlier present as 8 that affects the center, then the best measure of center for third period must be Median.
