Answer:
The answer is 10. Hope this helps!
It would be: 8 - (1 1/4 + 2 3/8)
8 - (5/4 + 19/8)
8-29/8
64-29/8
35/8 inches OR 4.375 is your answer
Answer:
A = 82.82
B = 72.53
C = 61.58
D = 53.55
Step-by-step explanation:
First, determine the percentile at which the cutoff grade in each letter grade interval falls on and find the equivalent z-score:
A: (100-10) = 90-th percentile
z-score = 1.282
B: (100-10-30) = 60-th percentile
z-score = 0.253
C : (100-10-30-40) = 20-th percentile
z-score = -0.842
D: (100-10-30-40-15) = 5-th percentile
z-score = −1.645
The value 'X' for each cutoff can be found by applying the z-score equation:
Where μ is the mean and SD is the standard deviation
Therefore, the cutoffs are:
That outlier will appear as a single blip of data, but it will be far
away from the central part of the histogram. It will not be that visible
if there is a lot of data, since 1 outlying data point will just show a
very low height compared to the central data near the mean/median/mode,
where there will be higher frequencies and higher bars of data.
If these are the choices:
<span>A.The outlier will appear as a tall bar near one side of the distribution.
B.The outlier will appear as a bar far from all of the other bars with a height that corresponds to a frequency of 1.
C.Since a histogram shows frequencies, not individual data values, the
outlier will not appear. Instead, the outlier increases the frequency
for its class by 1.
D.The outlier will appear as the tallest bar near the center of the distribution.
</span>
Then the most accurate answer will be B, since it's just a single value with a bar corresponding to a frequency of 1.
Answer:
1/2
Step-by-step explanation:
● 1/4 + 4(1/2 - 3/4 )^2
To make it easier convert the fractions to decimal numbers.
● 1/4 = 0.25
● 1/2 = 0.5
● 3/4 = 0.75
So the expression will be:
● 0.25 + 4(0.5 - 0.75)^2
Calculte first 0.5-0.75 (0.5-0.75= -0.25)
● 0.25 + 4 × (-0.25)^2
-0.25^2 is the same as 0.25^2
● 0.25 + 4 × (0.25)^2
0.25^2 is 0.0625
● 0.25 + 4×0.0625
Multiplication has the priority (4 ×0.0625) wich is 0.25
● 0.25 + 0.25
● 0.5
0.5 is 1/2
So the answer 1/2
