The diagonal of a TV is 30 inches long. Assuming that this diagonal forms a pair of 30-60-90 right triangles, what are the exact
Mama L [17]

Your answer is A: 15 inches by 15√3 inches.

We can use trigonometry to solve this. If we draw out one of the triangles we can label the 30 inch side as the hypotenuse, and then the other sides as the opposite and adjacent. Then we just have to find the lengths of these.

To find the opposite, we use the trigonometric ratio sinθ = opposite ÷ hypotenuse, and thus the opposite is sin(60) × 30 = 15√3

Automatically now we know the answer is A because that is the only option with 15√3 as a side, but you could also solve using cosθ = adjacent ÷ hypotenuse and get the other side.

I hope this helps!

Contestants on a game show spin a wheel with 242424 equally-sized segments. Most of those segments show different prize amounts,
ycow [4]

Using the principle of probability, the probability that the outcome of both spins does not land on "<em>bankrupt</em><em>"</em><em> </em>is 1/144

<u>Given</u><u> </u><u>the</u><u> </u><u>Parameters</u><u> </u><u>:</u>

  • Total Number of possible outcomes = 24
  • Number of outcomes labeled bankrupt = 2
  • Labels which aren't labeled bankrupt = 24 - 2 = 22

<u>Recall</u><u> </u><u>:</u>

  • P(A) = <em>required</em><em> </em><em>outcome</em><em> </em><em>/</em><em> </em><em>Total</em><em> </em><em>possible outcomes</em><em> </em>

<u>First</u><u> </u><u>spin</u><u> </u><u>:</u>

  • P(not bankrupt) = 2 / 24 = 1/12

<u>Second</u><u> </u><u>spin</u><u> </u><u>:</u>

  • P(not bankrupt) = 2/24 = 1/12

P(<em>neither</em><em> </em><em>lands</em><em> </em><em>on</em><em> </em><em>bankrupt</em><em>)</em><em> </em><em>=</em><em> </em>1/12 × 1/12 = 1/144

Therefore, the probability that neither lands on bankrupt is 1/144

Use the distance formula to calculate the length of the leg CD
Karo-lina-s [1.5K]

To calculate the distance between two points on the coordinate system you have to use the following formula:

d=\sqrt[]{(x_1-x_2)^2+(y_1-y_2)^2}

Where

d represents the distance between both points.

(x₁,y₁) are the coordinates of one of the points.

(x₂,y₂) are the coordinates of the second point.

To determine the length of CD, the first step is to determine the coordinates of both endpoints from the graph

C(2,-1)

D(-1,-2)

Replace the coordinates on the formula using C(2,-1) as (x₁,y₁) and D(-1,-2) as (x₂,y₂)

\begin{gathered} d_{CD}=\sqrt[]{(2-(-1))^2+((-1)-(-2))}^2 \\ d_{CD}=\sqrt[]{(2+1)^2+(-1+2)^2} \\ d_{CD}=\sqrt[]{3^2+1^2} \\ d_{CD}=\sqrt[]{9+1} \\ d_{CD}=\sqrt[]{10} \end{gathered}

The length of CD is √10 units ≈ 3.16 units

vitfil [10]

Answer:

a) P(2.9

And we can find this probability with the following difference:

P(-1

b) P(2.9

And we can find this probability with the following difference:

P(-3.5

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Part a

Let X the random variable that represent the diameters of a population 1, and for this case we know the distribution for X is given by:

X \sim N(3,0.1)  

Where \mu=2 and \sigma=0.1

We are interested on this probability

P(2.9

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(2.9

And we can find this probability with the following difference:

P(-1

Part b

X \sim N(3.04,0.04)  

P(2.9

And we can find this probability with the following difference:

P(-3.5
