Prove that the difference of two odd integers is even. give a justification at each step.
crimeas [40]
Let a, b be two odd integers. Then both can be written as

a=2k-1, k is an integer
b=2m-1, m is an integer

So,

a-b=2k-1-(2m-1)=2k-2m-2=2(k-m-1)

Since, k and m and 1 are all integers, then (k-m-1) is also an integer. Hence, 2(k-m-1) is an even integer.

Thus, a-b is even.

Suppose that the probability density function ofthe length of computer cables is f (x) = 0.1 from 1200 to1210 millimeters.a. Det
Ann [662]

Notice that f(x)=0.1 for 1200\le x\le1210 implies that f(x)=0 elsewhere, since

\displaystyle\int_{1200}^{1210}f(x)\,\mathrm dx=1

where X=x is a random variable representing cable lengths according to the PDF f(x).

a. By definition of expectation, the mean is

E[X]=\displaystyle\int_{-\infty}^\infty x\,f(x)\,\mathrm dx=0.1\int_{1200}^{1210}x\,\mathrm dx=1205

The variance is

\operatorname{Var}[X]=E[(X-E[X])^2]=E[X^2]-E[X]^2

where

E[X^2]=\displaystyle\int_{-\infty}^\infty x^2\,f(x)\,\mathrm dx=0.1\int_{1200}^{1210}x^2\,\mathrm dx=\frac{4,356,100}3

so that the variance is \frac{25}3, making the standard deviation \frac5{\sqrt3}.

b. The proportion of cables within specs is

P(1195

Solve the system of equations.
Anna35 [415]

Answer:

The answer is supposed to be (2,-3), but for some reason I don't see it as one of the choices.

(Please don't get mad or report this answer, the work is below, so you may see for yourself.)

Step-by-step explanation:

Since y equals both -6x + 9 and -3x + 3, we will simply write them into one equation:

-6x + 9 = -3x + 3

Next we will solve for x by isolating it:

So, first subtract 3 on both sides to get -6x + 6 = -3x. Next add 6x on both sides to get 6 = 3x. Then finally divide by 3 on both sides to get 2 = x or you can flip it to be x = 2.

Now that we know what x is, we can plug it back into one of the original equations. In this case we'll plug it into y = -3x + 3:

y = -3(2) + 3

-3 × 2 = -6 and -6 + 3 = -3

So: y = -3

Now we can plug each into an ordered pair (x,y), and your answer is (2,-3).

As always, don't forget to check your work (It's correct btw, I already checked) and I hope this helps you :)
