(Don't report the other guy, he needs points and I'll give you the answer)

The rock displaces 1800cm cubed of water -> The volume of it is 1800cm3

To calculate the volume of a right rectangular prism, we take width x length x height.

=> 10 x 12 x height = 1800

So, the height of the rock is 1800 : 120 = 15.

Gnesinka [82]

The given example is inductive reasoning.

<h3>What is inductive reasoning?</h3>

The method of arriving at a conclusion based on a series of observations is known as inductive reasoning. It is not a valid method of proof in and of itself.

We have the information that. Janelle got invited to a shopping spree with a friend and is supposed to meet her at the mall at 4:00 p.m. when she has gone to the mall in the past,

she has noticed that it takes about two hours for her to travel to the mall. she has also noticed that it takes her 30 minutes to get ready before leaving her apartment. she concludes that she needs to start getting ready at 0:30 p.m.

The given information is giving us the series of the data like we are having a sequence of the timing at what time what she did so we have a series of observations here.

Therefore the given example is inductive reasoning.

stiks02 [169]

Answer:

The next time Mahnoor visits the restaurant, there is:

--31 % chance for country music

--47% chance of rock & roll

--22% chance of blues

Completed question;

Mahnoor randomly selects times to walk into a local restaurant and observe the type of music being played. She found that the restaurant was playing country 11 times, rock & roll 17 times, and blues 8 times. Use the observed frequencies to create a probability model for the type of music the restaurant is playing the next time Mahnoor walks in.

Step-by-step explanation:

Given;

The number of times they were playing each type of music;

Country = 11 times

Roll = 17 times

Blues = 8 times

Total visits of Mahnoor = 11+17+8 = 36

Developing a frequency table and probability model for the type of music the restaurant is playing the next time Mahnoor walks in.

Probability = number of favourable outcomes ÷ total number of outcomes.

Music played  |  Frequency  |  Probability

country            |  11                 |  11/36 = .31 or 31%

rock & roll        |  17                |  17/36 = .47 or 47%

blues                |  8                 |  8/36 = .22 or 22%

Is there a relationship between the area and the perimeter of a rectangle?
Luden [163]
The are is A=W*L
The perimeter is P=2L+2W
So there is some form of relationship.
A/W=L and P-2W=2L
A/W=L and (P-2W)/2=L
A/W=(P-2W)/2
2A/W=P-2W
2A=PW-2W^2
If you line them up according to the quadratic formula you can have 
2W^2-PW+2A=0 where W is the variable equivalent to X in normal circumstances and P and A are set values.  There is always a relationship between two numbers, or at least you can almost always create your own relationship.  This may seem rather complicated but this is a complicated question and I applaud you for asking something of this sort.

If tan x =8/15 and 0°&lt;x&lt;90°,find the value of cos x​
Shtirlitz [24]

9514 1404 393

Answer:

  15/17

Step-by-step explanation:

cos(arctan(8/15)) = 15/17

__

You could assume the ratio values 8 and 15 represent the opposite and adjacent sides of a right triangle. Then the hypotenuse is ...

  h = √(8² +15²) = √289 = 17

The cosine is the ratio of the adjacent side to the hypotenuse, so is ...

  cos(x) = 15/17
