You need two pieces and 1 has to be 2x longer than the other
set x as the smaller piece (easier to always go with the smaller value as x)
the other piece is 2x (double in size)
your equations would be 3x=240>>> x= 60
so smaller piece/ x= 60
bigger piece/ 2x= 120
Answer:
The mean of X is 122.5 and the standard deviation is 7.9.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe that the overall state of moral values is poor, or they do not believe this. The probability of an adult believing this is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem, we have that:
So
The mean of X is 122.5 and the standard deviation is 7.9.
Answer:
Below
Step-by-step explanation:
You can use it if you added a hight.
When you a hight you are creating a right triangle. If not you cannot use directly
Answer:
-2/3 is the y intercept
Step-by-step explanation:
So to find the y-intercept you must first put this in Slope-intercept form, I believe the form it is in right now is called standard form.
To get it into slope intercept form, we have to isolate y:
subtract 2x from both sides:
-3y = -2x + 2
Divide both sides by -3:
y = (2/3)x - 2/3
Now that we have slope-intercept form, we can find the y-intercept. We know slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. In this case the y-intercept is -2/3.
Hope this helps!
