Answer:
Table C
Step-by-step explanation:
Given
Table A to D
Required
Which shows a proportional relationship
To do this, we make use of:
Where k is the constant of proportionality.
In table (A)
x = 2, y = 4
x = 4, y = 9
Both values of k are different. Hence, no proportional relationship
In table (B)
x = 3, y = 4
x = 9, y = 16
Both values of k are different. Hence, no proportional relationship
In table (C):
x = 4, y = 12
x = 5, y = 15
x = 6, y = 18
This shows a proportional relationship because all values of k are the same for this table
The answer is D
Have you ever heard of rise over run rise/run
Y/x. Well in this case the run is One with a rise of four
Answer:
60 degrees.
Step-by-step explanation:
We use trigonometry of a right angled triangle:
Adjacent side = 20 ft, Hypotenuse = 40 ft.
cos x = adjacent / hypotenuse = 20/40 = 1/2
x = 60 degrees.
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
