Which problem will have the greater quotient, 376.0 divided by 92 OR 376 divided by 93.01? Explain how you know logically
xxTIMURxx [149]
1. 376.0 / 92 = ?

2. 376 / 93.01 = ? 

So the question asks us which quotient will be greater. In plain English it is asking which of the two, ?, will be greater. Seeing how the question is asking for a logical answer we are not going to actually solve the problem. Instead we will use logic. 

First let's do some examples, and explain more in-depth how division works.

A. 6/3 = 2
B. 6/2 = 3

In this case, B is greater than A.

Greater than being any number that is larger than another on a scale reading from left to right, so if you were to count out all the way to the number the one that comes first is lower in value than the one that comes second.

Division works like this: Say we have a full delicious pie. We want to divide it up into 12 pieces so all our friends can have some. What we're doing is simply finding a value that if multiplied by 12 would equal our 1 pie. If you instead divided it by 24 you would have even SMALLER pieces of pie. 

A. 5/2
B. 5/3

You might not be able to answer this one, but say our pie is equal to 5. For A. imagine we take a pie and cut it in half. Now for B. imagine a pie and cut it into 3 equal sized pieces. Which one will have the bigger individual pieces? A. will!

Keep in mind that the individual size of the piece would be the quotient (the quotient just means the answer to a division problem).
 
Now to quickly dismiss the 376.0, When you add 0's to the DECIMAL you do not change the value.
If you did then, 0.0 wouldn't still be 0. Or 1.0 wouldn't still be 1. The .0 is just a place holder and signifies nothing. Don't get this confused with adding a zero to the end of a number, because that does change the value (except in the case of 0). 1 with an extra zero becomes 10, and so on. 

So let's tackle this problem!
A. 376.0 / 92
B. 376 / 93.01

In the end the .0 is meaningless so it's the same as this: 
A. 376 / 92
B. 376 / 93.01

All we are looking for is the dividend that is smaller. (A dividend being what is dividing a number. In the case of 4/2 the dividend is 2. 5/2, the dividend is 2. 6/3, the dividend is 3. So in other words the dividend is the number after the division symbol, or in this case the slash (they are the same)).

So let's see, which is smaller? 92, or 93.01.
Whichever is smaller is going to have a bigger slice of pie than the other one. So, 92. Is our answer.

Note that this reasoning worked, because the numerator (376) is the same on both division problems. If they differed we wouldn't be able to use the same logic (at least as easily as we did in this problem!).

Which of the following is a correct interpretation of the expression -7- (-11)?
Brilliant_brown [7]

Answer:

B. Start at -7 on the number line and move 11 to the right.

Step-by-step explanation:

<u>Given:</u>

  • - 7 - (-11) expression

We can add or remove only positive numbers on the number line to get it  correct, so we need to open the parenthesis. When evaluated we get:

-7- (-11) = - 7 + 11 = 4

<u>Correct interpretation of of this expression is:</u>

  • Start at -7 and add 11, thus move 11 points to the right, to get 4 as final point.

<u>Correct choice is:</u>

  • B. Start at -7 on the number line and move 11 to the right.

Could you please help me with this problem?
NeTakaya

First Question:

Number of trapezoids - 6

Perimeter - 72

3 + 3 + 3 + 6 = <u>15</u>

3 + 3 + 3 + 3 + 6 + 6 = <u>24</u>

3 + 3 + 6 + 3 + 3 + 6 + 3 + 6 = <u>33</u>

15 + 24 + 33 = <u>72</u>

Second Question:

Number of cubes - 6

Surface area - 24 (probably 480 since it said <em>area</em>)

first cube - 6 ones

second cube - 8 ones

Third cube - 10 ones

you could do 6 + 8 + 10 = 24 or add up all the ones (1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1) and you will still get 24

(It said <em>area</em>, and area means to multiply so maybe its 6 x 8 x 10 = 480 and not 6 + 8 + 10)

Anyways have a good day/night :) I might be wrong, but I hope I helped at least a little

For a given IQ test, an individual is considered a genius if their score falls more than three standard deviations from the mean
ki77a [65]

Answer:

P(Z>3) = 1-P(Z

So then the probability that an individual present and IQ higher than 3 deviation from the mean is 0.00135

And if we find the number of individuals that can be considered as genius we got: 0.00135*1500=2.025

And we can say that the answer is a.2

Step-by-step explanation:

1) 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".  

2) Solution to the problem

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

X \sim N(\mu=?,\sigma=?)  

We are interested on this probability

P(X>X+3\mu)

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}

And we can find the following probablity:

P(Z>3) = 1-P(Z

So then the probability that an individual present and IQ higher than 3 deviation from the mean is 0.00135

And if we find the number of individuals that can be considered as genius we got: 0.00135*1500=2.025

And we can say that the answer is a/2.0
