Find the value of the variable(s). If your answer is not an integer, leave it in simplest radical form.

Georgia [21]

Answer:

D

Step-by-step explanation:

First, let's find x.

We know that one of the angles is 30. The side opposite to than angle is 11, and x is the adjacent side to it. Therefore, we can use the trig function tangent.

Recall that:

$\tan(x)=opp/adj\\$

Plug in 30 for the angle, 11 for the opposite, and x for the adjacent. Solve for x by cross-multiplying:

$\tan(30)=11/x\\x\tan(30)=11\\x=11/\tan(30)$

From the unit circle, recall that tan(30) is equal to one over the square root of 3. Thus:

$x=11/(1/\sqrt3)\\x=11\cdot\sqrt3\\x=11\sqrt3$

Now, we can use the Pythagorean Theorem to find y. y is the hypotenuse. Thus:

$c^2=a^2+b^2\\c^2=(11\sqrt3)^2+11^2\\c^2=121(3)+121\\c^2=4(121)\\c^2\sqrt{4(121}=2(11)=22$

Answer:

True

Step-by-step explanation:

A parallelogram always has two pairs of opposite parallel sides with four right angles. Furthermore any polygon with 2 opposite pairs of parallel sides would be considered a parallelogram.

Answer:

The probability that the first subject to be a universal blood donor is the seventh person selected is 0.0511

Step-by-step explanation:

Let's start defining the random variable X.

X : ''The first success is on the xth trial''

X can be modeled as a geometric random variable with the following probability function :

$P(X=x)=p(1-p)^{x-1}$
