I believe it’s letter c if it’s saying 2/4 and reduce down to 1/2
Step-by-step explanation:
√a = 1√a so we can solve them easily:
b) 3√7 -√7= 3√7 - 1√7 =( 3-1)√7= 2√7
d) 5√6 - 2√6+√6= (5-2+1)√6 = 4√6
g) √2+2√2= 3√2
j) √5+5√5 - 3√5 = 3√5
k) 2√3 + √3 - 5√3= -2√3
I) 5√11 + 7√11 - √11 = 11√11
12 girls out of 19, how many out of 76
12 - x
19 - 76
Cross product:
19x= 1152
/19. /19
x= ~61
There are (around) 61 girls
Answer:
3 games
Step-by-step explanation:
Here, the same amount of money was spent at different golf clubs. The amount spent at Man vista golfing is (3 + 7.5g). The amount spent at Pinz golfing is (12 + 4.5g)
We equate both to yield the following:
(3+7.5g) = (12+4.5g)
7.5g - 4.5g = 12 -3
3g = 9
g = 9/3
g = 3
18,38,38,40,44,44,44,46,48....
the mean with the outlier (18) included is : 360/9 = 40
38,38,40,44,44,44,46,48
the mean with the outlier (18) excluded is : (360 - 18) / 9 = 342/9 = 38
so when the outlier is removed, the mean is 2 points less
