Answer: 1.460
Step-by-step explanation:
Given : Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college.
Let 
represents the population mean .
Then, the set of hypothesis will be:-
We assume that this is normal distribution.
Sample size : n = 10, which is a small sample (n<30) ,s o we use t-test.
Sample mean : 
Standard deviation : 
The test statistic for population mean for small sample is given by :-
Hence , the value of test statistic = 1.460
Answer:
-4, -2, 0, 2
Step-by-step explanation:
the expression for the integers are; x, x +2, x + 4, x + 6
4x + 12 = -4
4x = -16
x = - 4
your integers are; -4, -2, 0, 2
if you add those your answer will be -4
Answer:
No solution
Step-by-step explanation:
To find the solution to 3x - 9 equals 3(x - 5), we would have to solve for x.
First set the two expressions equal to each other.
3x - 9 = 3(x - 5)
Now we can distribute the 3 on the right side.
3x - 9 = 3x - (3 * 5)
Simplify
3x - 9 = 3x - 15
Now lets try to get x alone on one side of the equality. Subtract 3x from both sides to cancel out of 3x on the right side.
3x - 9 - 3x = 3x - 15 - 3x
-9 = -15
And as you may have realized, -9 does not equal -15.
Why did the x disappear? Why did we end up with -9 = -15 which is clearly a false statement? This is because the the lines y = 3x - 9 and y = 3(x - 15) are parallel. Thus, they will never intersect and the equality 3x - 9 = 3(x - 5) will have no solution.
So there is no solution.
I hope you find my answer to be helpful. Let me know if you have any questions. Happy studying.
The answer is 46000
because 1 ton is 2000 pounds and I did 2000 * 23

We can't really do this without seeing 28, but I can give you an educated guess. The best way for me to proceed is to solve c.
The conjecture is that x = a + b. You should always find that to be true. C is the clincher.
Here's how you do that.
x + c = 180o That's true because all straight lines have 180o. If two angles make up the straight line that means that they are always equal to 180o So x + c = 180o
Now we move to the next step. All triangles also have 180o. That means that a + b + c = 180o
So we have two conditions that equal 180o. Equalities can be equated to one another.
a + b + c = x + c Subtract c from both sides.
a + b = x.
Study what has happened. Put in mathese, the two remote interior angles equal the exterior angle, which is what you are trying to prove.
Summary
a cannot be solved without 28
b you should say that the two remote angles (a and b) will always total x
c The proof is provided for you.
