For this, you want to find the Factors, the Common ones and then the Greatest of those.
*Always list factor in pairs so that none are missed/left out

First, Factors of 32
1, 32
2, 16
4, 8

Now, Factors of 81
1, 81
3, 27
9

The next step is to highlight/circle the common factors

1,

As there is only one common factor, that is the greatest.
The GCF is 1

A candy store grab bag contains 10 pieces of sour candy, 12 pieces of chocolate candy, and 6 pieces of sweet candy. If you selec
harkovskaia [24]

Step-by-step explanation:

so we're making two draws *with* replacement (this is important)

step 1: for the first draw, it wants the probability of getting a sour candy. to calculate this:

(# of sour candy) / (total # of candy)

step 2: for the second draw, it wants the probability of *not* getting a sour candy. to calculate this, you can calculate 1 - (the probability form part 1).

step 3: to find the probability of both events happening together, simply multiply the probabilities from part 1 and 2 together

side note: for step 2, you can only do this because the candy is being replaced. if there were no replacement, you'd have to re-calculate (# of non-sour candies) / (total after the first candy is drawn)

If two measurements are very close to each other, then they are ____..
erik [133]

The <em>correct answer</em> is:


B) precise


Explanation:


Precision can be broken down into two pieces:

<em>Repeatability </em>- The variation observed when the same person measures the same thing repeatedly with the same device.

<em>Reproducibility</em>: The variation observed when different people measure the same thing using the same device.


If two measurements are very close to each other, this gives repeatability. If the measurements were made by different people, this gives reproducibility.


<em>Accuracy</em>, however, describes the difference between the measurement and the thing's actual value. This would not involve getting the same result repeatedly; it would be getting the <em>correct</em> value.
