Answer:
His actual score is 15
Step-by-step explanation:
Here, we are interested in calculating Wayne’s actual score on the ACT
when we say the scores have being standardized, it means the score was reported in terms of the z-score and not the initial raw scores.
Now, mathematically, for the scores to have a negative z-score, it means it is actually below the mean.
The formula for the z-score or standard score is given below;
z-score = (x - mean)/SD
where in this case, x = ? which is the score we are looking for , z-score = -0.5 , mean score = 18 and standard deviation of the scores = 6
So, substituting these values into the z-score equation, we have;
-0.5 = (x-18)/6
x-18 = 6(-0.5)
x -18 = -3
x = -3 + 18
x = 15
It would be 56 degrees since it's a vertical angle and to get the obtuse angles you just subtract 180 from 56 and there's your answer. Hope this helped! (':
Answer:
-3
Step-by-step explanation:
3 times 6 is 18
3 times -2x is -6x
put -6x on the other side and divide 18 by -6x and you get -3
The ratio of 114 hours to 13 days is 19:52.
<h3>How to calculate the ratio?</h3>
It should be noted that ratio is simply used to show the comparison between two things that are illustrated.
In this case, we want to calculate the ratio of 114 hours to 13 days. It should be noted that 24 hours make one day. Therefore, 13 days will be:
= 13 × 24 = 312 hours.
The ratio of 114 hours to 13 days will be:
= 114 / 312
= 19 / 52
The ratio is 19:52.
