Answer:
ALISSA
Step-by-step explanation:
Given the following scores :
NICO:
Score (x) = 81.6
Mean (m) = 72.6
Standard deviation (sd) = 15
EMILIO:
Score (x) = 225.3
Mean (m) = 205
Standard deviation (sd) = 29
ALISSA:
Score (x) = 8.08
Mean (m) = 7.2
Standard deviation (sd) = 0.4
STANDARDIZING THE DIFFERENT APTITUDE TEST SCORES:
OBTAINING THE ZSCORES :
Zscore = (x - mean) / standard deviation
NICO:
Zscore = (81.6 - 72.6) / 15
Zscore = 0.6
EMILIO:
Zscore = (225.3 - 205) / 29
Zscore = 0.7
ALISSA:
Zscore = (8.08 - 7.2) / 0.4
Zscore = 2.2
From the result of the Zscore, the best fit for the position is ALISSA
Step-by-step explanation:
surface area if pyramid=area of base+combined area of lateral faces.
area of base=8×8=64
combined area if lateral faces=area of one triangle:area=base×height
=8×12=96
Total surface area=64+96
=160m square
Yes it’s true
The answer comes out as 31,311
So 1,878,66 is divisible by 6 Is TRUE
Hope this helps *smiles*
Answer:
£600
Step-by-step explanation:
Katie gives 1/3 of the money to her sister.
1/3 of 1200 is 400, because 1200 divided by 3 is 400. So she gives 400 to her sister, which means she has 1200-400= 800 left.
When she gives 1/4 of the remaining to her brother, that means that we need to figure out how much 1/4 of 800 is. 800 divided by 4 is 200. So Katie gives 200 to her brother.
800 that she has remaining minus the 200 she gives to her brother leaves her with 800-200 = 600
B + 3/2*b + b + 45 + 2b - 90 + 90 = 540
Or, 4b + 3b/2 + 45 = 540
Or, (8b+3b)/2 = 495
Or, 11b = 990
Or, b = 90
Now,
b+45 = 135
3/2*b = 135
2b - 90 = 90
