Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college. You survey 10
neonofarm [45]

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 \mu represents the population mean .

Then, the set of hypothesis will be:-

H_0: \mu=15

H_a:\mu\neq15

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 : \overliene{x}=16.2\ lbs

Standard deviation : \sigma=2.6

The test statistic for population mean for small sample is given by :-

t=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

t=\dfrac{16.2-15}{\dfrac{2.6}{\sqrt{10}}}=1.45951276623\approx1.460

Hence , the value of test statistic = 1.460

The sum of 4 consecutive even integers is -4. What are the integers?
Lina20 [59]

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

What is the answer to 3x - 9 equals 3 (x-5)​
viktelen [127]

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.

I need help on c and d please
Dennis_Churaev [7]

A

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.
