Answer:
x = 8
Step-by-step explanation:
30x = (60)(40)
30x = 240 Multiply 60 and 40
x = 8 Divide 30 from both sides
Here is how to work the problems and write the expressions.
Subtract 6 from both sides ( subtract 6 form 6 to get 0 then subtract 6 form -4 to get 2) that’s the first step
range is 31.5, variance is 161.3 and standard deviation is 12.7 for a sample of top 10 annual TV personalities.
Step-by-step explanation:
- Average is mid-point is the mid-point of the data but can skew....
- On the Left or Right is there are higher or lower values.
- Range is difference between maximum and minimum value of data.
- Variance, measure of variability of data but squared or mean deviation.
- Standard deviation is the most important variability.
- It helps in finding out variability with 3 sigma deviations.
- Standard deviation is square root of variance and each sigma explains...
- The data lieing between or within the extreme values.
Your answer is going to be “ x>-3 OR x<-3”
