Answer:
19448 ways
70572902400 ways
Step-by-step explanation:
(a)
To arrange 17 books on a shelf from a possible we use the combination formula :
nCr = n! ÷ (n-r)!r!
17C10 = 17! ÷ 7! 10!
17C10 = 19448 ways
To arrange the books in alphabetical order :
2)
In question, 2, the order of arrangement matters ; hence, we use permutation ;
nPr = n! ÷ (n-r)!
17P10 = 17! ÷ (17 - 10)! = 17! ÷ 7!
17P10 = 70572902400
Hi! So for the first one, the answer is D. I can't see the numbers to estimate where the data begins, but for the males the minimum is about 100 i think, while the max is about 240, leaving a range for the males data of about 140, while the women have a range of about 60 (150-90), so there is greater variability in the males data.
For number 8 A, position 3 has the heaviest overall players due to the median being further to the right/higher, and it looks like 4 has the lightest. For B, it seems as if number 4 has outliers due to the two single dots away from their plot, indicating they don't fit within the average data for their position.
Distance=rate times time
rate=xmiles per hour
time=y hours
total distance=distance1+distance2
distance1=45mph times 2=90mi
distance2=30mph times 3=90mi
total distance=90mi+90mi=180mi
total is 180mi
The percentage by which the cost is increasing will be 75%.
<h3>What is the percentage?</h3>
The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The percentage of the 8th graders who want to go to the water slides is found from;
In the year 2000, a house was valued at $60 000.
In 2010, the same house was valued at $80 000.
The percentage value is found as;
Hence the percentage by which the cost is increasing will be 75%.
