Add all the numbers: 18 + 14 + 8 + 22 + 25 + 8 = 95 And divide by how many numbers are in the set (there are 6) 95 / 6 = 15.8333333333333... Rounding to the nearest tenth gives you 15.8 15.8 is the correct answer.
Um, okay, that's what I said basically.
NOTE: If this is a short answer question (where you type in your answer), please do not use this as this type of work is usually not accepted for a good grade. Take the distance in miles and divide it by the time in hours: 17.25 / 1.5 = 11.5 23 / 2 = 11.5
Can you describe the table of Kevin's speeds and rides?
What does the histogram look like? You can describe it using words.
Maybe try describing what the source data looks like? Is it a set of numbers? Or is it something else?
Well, at least the website improved the Bot's answering style and profile picture, and the mathematical part as well. I do want to clarify that while Bot's answer is correct, its explanation is wrong. You see, a proportional relationship is identified by a

Uh, this can be calculated on a calculator, but -26 is correct.
This answer has been human-verified as correct. Thanks for asking!
Despite Social Studies/History not being my strongest subject, I do believe the robot is correct.
Adjacent angles are *sometimes* congruent.
It's actually A
Sorry about that, the website's automated answering system needs improvement...
The air is thinner Hope this helps!
Robot (a.k.a [blank name]) is wrong yet again. We'll call "your" lunch "L" and "your friend's" lunch "f" Make 2 equations: L + f = 19 L - f = 3 Rewrite one of the equations (in this case, the second one) L - f = 3 L = 3 + f Substitute L for the first

Your answer is now human-verified to be correct. Thanks for asking!
Its A. k = 7 Just think about it, you take 6, divide it by 7, the multiply by 7. Dividing then multiplying by the same number results in cancellation of the operation. In other words, you end up with 6.
Sorry, about that, the website's automated answering robot is a bit, well, weird. The answer is 130
At the top of the board, the diver has PE = mgh At the bottom, he has KE = (1/2)*m*v^2 = mgh It takes a 1500 N force 5 meters to decelerate a 50 kg mass traveling at v So, you can find the initial velocity Which also means you can find the KE Make KE equal
Just plug in the variable: 4/5 * 5/8 Then cross-simplify and simplify again: 4/5 * 5/8 = 4/1 * 1/8 = 1/1 * 1/2 = 1 * 1/2 The Identity Property of Multiplication states that a number multiplied by 1 equals itself so 1 * 1/2 = 1/2 Your answer is B. 1/2
Okay, I am assuming that the numberS are 412, 466, and 208 and not a single number of 412 million+ (a car is not the expensive) Mean: 362 Median: 412 Mode: No mode Range (if needed): 258

Um what are the possible choices???
It SHOULD be B. though Not sure, but it sounds more reasonable than the automated message.
Okay, let's break this down: There is a ratio of 2:3 in the box. Convert the ratio to a fraction (simply because you can). 2/3 = x/y (just assuming variables) x + y = 200 Doing mental math tells me that 80 + 120 = 200 and 2/3 = 80/120 Okay, now 80/2 = 40
Find the GCF, or greatest common factor of the denominators (2, 3, and 4) and convert the fractions accordingly. After the conversion, we have: 6/12 + 4/12 + 3/12 = 13/12 = 1 1/12 = 1.0833333... Depending on the answer you need, you can choose any of the

Its actually: C. It drove down the cost of industrial cloth. This question I have good knowledge of ;) But correct me if I'm wrong, and my greatest apologies if I am wrong.
Add 4 to both sides to get 24 = 6x
The answer you received is now human-verified to be correct. Thanks for asking!
You're welcome, and have a great rest of the day, (hopefully you can get your question correct) :)
Y'know, "nullification" (which is often repeated through the letter) means unfair law. I'm not sure but, it might be C Again I am not sure, so please take this into your own consideration.
The answer you received is now human-verified to be correct. Thanks for asking!
Actually, robot is wrong again... It wasn't noted the starting temperature so let's assume it is 20 C Then, Initial diameter of the rod D1 = 4 mm Final diameter of the rod D2 = 3.993 (at least) Initial Temperature of the rod T1 = 20 C Final Temperature of
Any chance you can copy and paste the excerpt?
Unless we know what "b" is, the expression 32b-20 cannot be simplified anymore.
It is way lower: To find the mass of water at a given temperature and relative humidity, you have to know the mass of water vapor in a cubic meter of air when the air is saturated at the temperature. First calculate the volume of the room in m3. Multiply
Great explanation Laurialla! You see,scientists predict the weather based on certain patterns in the weather, though there are some unknown factors that scientists have not confirmed yet. Thus, predicting the weather is probable, not definite.
I know this is not the subject I major in, but may I ask what letter does the question refer to?
36 points that is (55 + 35)/5 * 2 = 36 Robot wrong again...
What are the statements???
Small Intestine (not the stomach, I know, that is a common misconception)
Revision: the variable I used was "x" but I meant to use "d" Sorry for the confusion
Use a proportion, with the map scale as one fraction, and the other fraction having the unknown quantity (which is the actual distance). We will represent the unknown quantity using the variable "d" but you can use "x" as well. Proportion: 1/20 = 3.5/x
Seriously, any questions (relating to STEM)
