Answer:

$(3x+14)+(8x-21)=180°$

Step-by-step explanation:

Angles with measures $3x+14$ and $8x-21$ (or pmore precisely, vertical angle to angle 8x-21) are supplementary (add up to 180°).

Converse to same-side interior angles theorem states that If two same-side interior angles are supplementary, then l║p.

So, to prove that lines l and p are parallel, you have to show that angles $3x+14$ and $8x-21$ are supplementary.

Thus,

$(3x+14)+(8x-21)=180°$

We have n = 100 many random variables xi 's, where the xi 's are independent and identically distributed bernoulli random variab

Alex777 [14]

Recall that for a random variable $X$ following a Bernoulli distribution $\mathrm{Ber}(p)$ , we have the moment-generating function (MGF)

$M_X(t)=(1-p+pe^t)$

and also recall that the MGF of a sum of i.i.d. random variables is the product of the MGFs of each distribution:

$M_{X_1+\cdots+X_n}(t)=M_{X_1}(t)\times\cdots\times M_{X_n}(t)$

So for a sum of Bernoulli-distributed i.i.d. random variables $X_i$ , we have

$M_{\sum\limits_{i=1}^nX_i}(t)=\displaystyle\prod_{i=1}^n(1-p+pe^t)=(1-p+pe^t)^n$

which is the MGF of the binomial distribution $\mathcal B(n,p)$ . (Indeed, the Bernoulli distribution is identical to the binomial distribution when $n=1$ .)

A base ball diamond is square.The distance from home plate to first base is 90 feet.what is the distance from home plate to seco

Elena-2011 [213]

Because it is square, the distance from home to first base is the same as first base to second base.

Home to First is one side of a right triangle, first to second is the second side of the right triangle and then home to second base would be the hypotenuse of a right triangle.

Using the Pythagorean Theorem we can solve for the hypotenuse:

Let C = the hypotenuse:

90^2 + 90^2 = c^2

8100 + 8100 = c^2

16200 = c^2

c = √16200

c = 127.279 feet, round to 127 feet.

What is the domain of the function on the graph

sergey [27]

Answer:

<h3>Domain [-3 , ∞ ]</h3>

Step-by-step explanation:

Domain is the set of all inputs for which the given function is defined.

graphically it represents the shadow of the graph taken on the x axis from above and below the x axis

Here is the shadow will be formed from -3 till +∞, hence we have our domain as [-3 , ∞ ]
