Answer:20 ^v^ Please follow me
Step-by-step explanation:
200/40=5
5+15=20
Because you can't divide 5 evenly
we will check each options
option-A:
For solving any equations , we always isolate variables on anyone side
For exp: x+7=1
so, this is TRUE
option-B:
For solving system of equations
For exp:
x-y=1
x+y=3
If we use addition , we could easily solve for x and y
so, this is TRUE
option-C:
We always solve problems using conventional method
we do not guess
so, this is FALSE
option-D:
We often reverse order of operation
For exp:
(x-2)^2-3=0
so, this is TRUE
option-E:
For linear equations , we always get one solution , infinite solutions or no solutions
so, this is FALSE
Answer:
The probability distribution is Normal continuous
Step-by-step explanation:
The basic idea is that velocity values have different noise level and an important thing regarding continuous probability distributions is that the probability of the random variable is equal to a specific outcome is 0
In other words, is practically impossible that one value of velocity could be the same as others.
It’s rational because the square root of 0.49 is 0.7
