Hi the number 0.0149856 hope that helps
Answer:
Step-by-step explanation:
given are two vectors
a) A+B = sum of twovectors = simply adding corrsponding compnents
=
Magnitude of the above vector =
Direction is making an angle of arc tan (-3) with x axis
b) A-B = Difference
=
Magnitude of difference vector =
Direction is making an angle of arctan (1/2) with positive x axis.
(angle = arctan (jcomponent/icomponent)
Answer:
Step-by-step explanation:
ΔADC and ΔDBC are similar (AAA)
Therefore the cooresponging sides are in proportion:
Substitute:
<em>cross multiply</em>
Answer:
x = 12 and x = -4
Step-by-step explanation:
abs (x-4) = 8
When we have absolute value equations, we get two solutions, one positive and one negative
x-4 = 8 and x-4 = -8
Add 4 to both sides
x-4+4 = 8+4 x-4+4=-8+4
x = 12 and x = -4
Answer:
14.81% probability an individual large-cap domestic stock fund had a three-year return of at least 19%
Step-by-step explanation:
Problems of normally distributed samples are 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 is the probability an individual large-cap domestic stock fund had a three-year return of at least 19%
This is 1 subtracted by the pvalue of Z when X = 0.19. So
has a pvalue of 0.8519
1 - 0.8519 = 0.1481
14.81% probability an individual large-cap domestic stock fund had a three-year return of at least 19%
