Answer:
1) 4/35
2) 11/14
3) 5/6
Step-by-step explanation:
First find the number of selections possible.

There are 210 possible selections. Now we can determine the possibility for each group. For the first probability, since we only want one member from each committee, you would create a fraction by (group members in total / group member being extracted). For this instance, since its only one, we will do whole numbers. Multiply each other.

The probability for each member to get selected from each kind is :
or can be simplified to
.
The probability of (I assume) at least one administrator is slightly different. Separate our two selections, the other three and the administrator. Find the number of selections possible for the other three... 4+3+2 = 9 others.
Find the probability for both a administrator included and three others.


The probability for an administrator and the other three is 165/210 or 11/14.
For the last one, you will figure out what the probability is for no director and use that % to substract from 100.
4+2+1 = 7
Get selections possible.

Get probability of no director.

Substract 1/6 from 100%
1 - 1/6 = 5/6
The probability of having at least one director is 5/6.
Answer:
$35
Step-by-step explanation:
If Fred has 227 total and ends up with 17, do 227-17 to determine how much he spent. ($210). If he bought 6 books, then divide $210 by 6.
Hence, each book was $35
Answer:
Hi!
The correct answer is d) 1 over 15 minus 1 over x equals x over 35.
Step-by-step explanation:
We know the amount of time that Byron can fill a drying rack with dishes: 15 minutes.
We know the amount of time that Byron can fill a drying rack with dishes while Emmitt is taking dishes out of the drying rack: 35 minutes.
We don't know the amount of time that Emmitt can take dishes out of the drying rack: x minutes.
So, if Byron is filling the drying rack in 15 minutes and Emmitt is taking out the dishes at x minutes, it takes 35 minutes to fill the drying rack.
<em>// multiply by 105x both sides.</em>
<em>// simplifly</em>
<em> //substract 3x and add 105 in both sides</em>
<em>// solve</em>
<em>//</em> <em>divide by 4 in both sides</em>
<em>// solve</em>

It makes sense that Byron fills the rack faster than Emmitt empties the rack.
Answer:
option B
Step-by-step explanation:
The symmetric distribution have close or approximate values of median and mean. In the given scenario mean is 48.5 and median is 33. We can see that the both values significantly differs. Also, given mean is greater than median(48.5>33) . Thus, the distribution is positively skewed and not symmetrical.
Hence, the distribution is skewed because mean and median significantly differ from each other.
Answer:
0.4
Step-by-step explanation:
If we count up all of the colored squares, we will get 28. And if we count the non-colored squares we will get 72.
Now, we take 28 and we divide it by 72. This will get us 0.3888888. That number rounded up is 0.4.
Hope this helps and if it does, don't be afraid to give my answer a "Thanks" and maybe a Brainliest if it's correct?
