Orlov [11]3 years ago

Answer:

The ratio for sin(X) is \frac{\sqrt{119} }{12}

The ratio for cos(X) is \frac{5}{12}

Step-by-step explanation:

- The ratio of the sine of a right triangle is:

sin(\alpha)=\frac{opposite-side}{hypotenuse}

Since we need the ratio for angle X, \alpha =X. From the picture we can infer that the opposite side of X is \sqrt{119}. The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:

sin(X)=\frac{\sqrt{119} }{12}

- The ratio of the cosine is:

cos(\alpha)=\frac{adjacent-side}{hypotenuse}

Similarly, \alpha =X, adjacent side = 5, and hypotenuse = 12, so

cos(X)=\frac{5}{12}

Answer:

Sin X =√119/12

Cs X = 5/12

Step-by-step explanation:

It is given a right angled triangle.

<u>Points to remember</u>

Sin θ = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

<u>To find the value of Sin X  </u>

Here X is an angle

Opposite side = √119

Hypotenuse = 12

Sin X = Opposite side/Hypotenuse = ZY/XY = √119/12

<u>To find the value of Cos X</u>

Adjacent side of X = 5

Cos X = Adjacent side/Hypotenuse = XZ/XY = 5/12

Below is the data of ages at the local amusement park on a certain day.
nignag [31]

Answer:

39

Step-by-step explanation:

To find the intervals you will need to find the lowest and highest numbers, in this case, it would be 1 and 35.  A general rule would be 5-7 intervals, I will use 5.

Here are the intervals with the number of people that were in each:

1-7 (9)

8-14 (14)

15-21 (8)

22-28 (3)

29-35 (5)

14+9+8+3+5=39

Wee-Mobile is offering a cell phone family plan for its users. The breakdown of the cost of the plan per month is given below.
Stells [14]

The total cost for a 6-month plan for n lines is represented by the equation:

Cost = 660n + 100

This equation is in the slope intercept form. The coefficient of n represents the slope here.

In the given scenario the slope can be interpreted as the total variable cost for one line for a period of 6 months.

The variable costs are associated with a line are:

1) Unlimited data cost ($40 per month). So for 6 months this cost will be $240

2) Unlimited Call cost ($10 per month). So for 6 months this cost will be $60

3) Unlimited Text Message Cost ($10 per month). For 6 months this cost will be $60.

4) Cost of Phone ($300 per line)

Adding these costs up we get: 240 + 60 + 60 + 300 = $660

Thus, 660 represents the total cost per line for unlimited data, calls, text message and one phone for 6 months. Therefore, option A gives the correct answer.

A box is with a square base and open top is to be constructed and a total volume of 720 cubic inches is required. The cost of ma
katen-ka-za [31]

Answer:

  total cost = 8x^2 +17280/x

Step-by-step explanation:

Let x represent the base length. Then the area of the base is x^2, and the height is h = 720/x^2.

The area of the four sides is ...

  (4x)(h) = (4x)(720/x^2) = 2880/x

The cost of the base is ...

  base cost = 8x^2

And the cost of the sides is ...

  side cost = 6(2880)/x = 17280/x

The total cost of the box is ...

  total cost = base cost + side cost

  total cost = 8x^2 +17280/x

_____

<em>Comment on the cost function</em>

You will find this function has a minimum at x=∛1080 ≈ 10.260 in. The total cost is about $2526.35, and the box is 2/3 times as tall as wide. That aspect ratio makes any pair of opposite sides cost the same as the base, the generic solution to a cost optimization problem of this sort.

The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of at the freezing poin
tatyana61 [14]

Answer:

The 96^{th} percentile is 1.751                                    

Step-by-step explanation:

The following information is missing in the question:

Mean,

\mu = 0^\circ C

Standard Deviation,

\sigma = 1^\circ C

We are given that the distribution of distribution of errors is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.96

P( X < x) = P( z < \displaystyle\frac{x - 0}{1})=0.96  

Calculation the value from standard normal z table, we have,  

\displaystyle\frac{x}{1} = 1.751\\\\x = 1.751

P_{96} = 1.751

1.751 degree Celsius is the thermometer reading corresponding to 96^{th} percentile.
