4 *3 = 12
12 * 20 = 240
240 / 2 = 120 units^3
answer is C
Answer:
Step-by-step explanation:
Hello!
The variable of interest is
X: mark obtained in an aptitude test by a candidate.
This variable has a mean μ= 128.5 and standard deviation σ= 8.2
You have the data of three scores extracted from the pool of aptitude tests taken.
148, 102, 152
The average is calculated as X[bar]= Σx/n= (148+102+152)/3= 134
An outlier is an observation that is significantly distant from the rest of the data set. They usually represent experimental errors (such as a measurement) or atypical observations. Some statistical measurements, such as the sample mean, are severely affected by this type of values and their presence tends to cause misleading results on a statistical analysis.
Using the mean and the standard deviation, an outlier is any value that is three standard deviations away from the mean: μ±3σ
Using the population values you can calculate the limits that classify an observed value as outlier:
μ±3σ
128.5±3*8.2
(103.9; 153.1)
This means that any value below 103.9 and above 153.1 can be considered an outlier.
For this example, there is only one outlier, that this the extracted score 102
I hope this helps!
D/dx ( cos (4x)) = - sin (4x) · d/dx ( 4x) = - 4 sin (4x)
Answer:
The value of y is 44.
Step-by-step explanation:
From your equation expressed the equation is probably 56 = y - 12
56 = y - 12 Add 12 to both sides to isolate the variable
44 = y
You must isolate the variable in order to solve equations with variables.
Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <u><em>ONLY</em></u> one side of the equation.
