Answer:
Θ = 157.7°
Step-by-step explanation:
Given
cosΘ = - 0.925
Since cosΘ < 0 then Θ is in the second or third quadrant.
Since 0° ≤ Θ ≤ 180° then Θ is in the second quadrant. thus
Θ = 
(- 0.925) = 157.7° ← angle in second quadrant
0.33 is rational 12 = Whole , real , irrational
Answer:
The correct option is C.
Step-by-step explanation:
Consider the provided information.
Four conditions of a binomial experiment:
There should be fixed number of trials
Each trial is independent with respect to the others
The maximum possible outcomes are two
The probability of each outcome remains constant.
Now, observe the provided options:
Option A and B are not possible as they doesn't satisfy the conditions of binomial experiment which is there must be fixed number of trials.
Now observe the option C which state that there must be fixed number of trials, it satisfy the condition of a binomial experiment.
Therefore, the correct option is C.
mu = 1100 = population mean
sigma = 275 = population standard deviation
x = 1400 = raw score
z = z score
z = (x-mu)/sigma
z = (1400-1100)/(275)
z = 300/275
z = 1.0909090909091 approximately
z = 1.09
Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).
The positive z score is due to Paula's raw score being above the mean.
Is there a picture so I can help
