Answer:
You expect to lose money 2.28% of the time.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What percentage of the time do you expect to lose money?
This is the pvalue of Z when X = 0. So
has a pvalue of 0.0228.
So you expect to lose money 2.28% of the time.
Answer:360 degrees in a circle divide by 4 is 90
Step-by-step explanation: there are 360 degrees in a circle so divide that by 4 and you get 90
Answer:
35

The entire angle is 70 degrees. If it is an angle Bi (which means two) sector, then divide it by two, which becomes 35 degrees.
Answer:
A) yellow = 4.5
B) pink = 8
C) orange =9
Step-by-step explanation:
A) yellow = 12-2-1-4.5=4.5

Answer:
6x-18
Step-by-step explanation:
(2x-6)+4(x-3)
you distribute the 4 by multiplying it with the variables within the parenthesis.
(2x-6)+(4x-3)
you can loose the parenthesis and group common factors together.
2x+4x-6-3
add
<u>6x-18</u>
