Answer:
C. 6.736
Step-by-step explanation:
The unmarked angle is 180-80-40 = 60 degrees. Given the angles of the triangle and one side length there is enough information to use the Law of Sines to solve the triangle--eliminating choice D.
The angle opposite x is larger than the angle opposite 5, so <em>x will be larger than 5</em>. That leaves only answer choice C: 6.736.
___
If you want to actually use the law of sines to determine x, you know that ...
x / sin(60°) = 5 / sin(40°)
x = 5·sin(60°)/sin(40°) . . . . . . multiply by sin(60°)
x ≈ 6.736
So we’re looking how many combinations we can make by selecting 5 items in a group of 17.
So we use n C r.
Where I the number of combinations of n objects taken r at a time.
So, 17 C 5
17! / (17-5)! 5! = 6188
(I hope this is correct)
Answer:
well there is 60% girls
Step-by-step explanation:
40% are boys out of 100%
So what you have to do is find out what added by 40 is 100 which is 60 so it's
40% boys to 60% girls
Answer:
The answer is 62
Step-by-step explanation:
First, you add 8 and 12 which is 20
Then, you add 20 and 18 which is 38
After that, you add 38 and 8 which is 46
Lastly, you add 46 and 16 which will equal to the total of 62

Answer:
Mode = 7
Median = 6
Mean = 5.2
Range = 7
Step-by-step explanation:
Mode:
The most repeated number is 7 (thrice).
Median:
First, arrange them in order.
1, 2, 3, 4, 5, 7, 7, 7, 8, 8
The two middle numbers are 5 and 7. Find their average.
(5 + 7)/2 = 6
Mean:
(3+7+2+4+7+5+7+1+8+8)/10 = 5.2
Range:
Largest number - smallest number
8 - 1 = 7
Hope this helps!
