Answer:

Step-by-step explanation:

$\dfrac{z}{2}=6\qquad\text{multiply both sides by 2}\\\\2\!\!\!\!\diagup\cdot\dfrac{z}{2\!\!\!\!\diagup}=2\cdot6\qquad\text{cancel 2}\\\\z=12$

Find the measure of each marked angle. Assume the lines are parallel.<br> (2x - 30)° = <br> (x+3)° =

Ket [755]

Answer:

Measure of each angle = 36°

Step-by-step explanation:

$(2x - 30) \degree = (x + 3) \degree \\ (alternate \: \angle \: s) \\ \\ 2x - 30 = x + 3 \\ \\ 2x - x = 30 + 3 \\ \\ x = 33 \\ \\ (2x - 30) \degree \\ = (2 \times 33 - 30)\degree \\ = (66 - 30)\degree \\ = 36 \degree \\ \\ (x + 3) \degree \\ = (33 + 3) \degree \\ = 36\degree$

6. Suppose that a fair coin is tossed 2 times, and the result of each toss (H or T) is recorded.

nekit [7.7K]

Answer:

a) $S= {HH, HT, TH, TT}$

b) $P(X=0) = (2C0) (0.5)^0 (1-0.5)^{2-0}= 0.25$

$P(X=1) = (2C1) (0.5)^1 (1-0.5)^{2-1}= 0.5$

$P(X=2) = (2C2) (0.5)^2 (1-0.5)^{2-2}= 0.25$

And we have the following table:

X | 0 | 1 | 2

P(X) | 0.25 | 0.5 | 0.25

Step-by-step explanation:

Let's define first some notation

H= represent a head for the coin tossed

T= represent tails for the coin tossed

We are going to toss a coin 2 times so then the size of the sample size is $2^2 = 4$

a. What is the sample space for this chance experiment?

The sampling space on this case is given by:

$S= {HH, HT, TH, TT}$

b. For this chance experiment, give the probability distribution for the random variable of the total number of heads observed.

The possible values for the number of heads are X=0,1,2. If we assume a fair coin then the probability of obtain heads is the same probability of obtain tails and we can find the distribution like this:

$P(X=0) = (2C0) (0.5)^0 (1-0.5)^{2-0}= 0.25$

$P(X=1) = (2C1) (0.5)^1 (1-0.5)^{2-1}= 0.5$

$P(X=2) = (2C2) (0.5)^2 (1-0.5)^{2-2}= 0.25$

And we have the following table:

X | 0 | 1 | 2

P(X) | 0.25 | 0.5 | 0.25

Domain and range of y=0.025x^2

aalyn [17]

Since it's not a domain restricted function anywhere, the domain of this function is (-∞, ∞). Because the x is squared, you will <em>never </em>get a negative answer, and therefore, the range is either (0, ∞) or {x: x > 0}. Hope this helps you out!
