Answer:
Step-by-step explanation:
The real part does not have i as a multiplier. It is 23.3.
The imaginary part* is the coefficient of i: 44.
_____
* There is some disagreement as to whether the imaginary part includes i or not. One source says the imaginary part is the part that has i as a factor (44i). Another source says the imaginary part is the real number that multiplies i (44). Above, we have used the latter definition. Please consult your curriculum materials for the definition you should use.
The answer for 338 to the nearest ten is 340
I'm going to do the calculus way because it's easier
max height,
take derititive of the equation
h'(t)=-9.8t+6
find what value of t makes it equal to 0
t=6/9.8
if we inputed it for t we get
h(6/9.8)=2.43673...
2.43673...>2.4 so we don't need to change anything
10q - 30 = 10 · q - 10 · 3 = 10(q - 3)
we need to find the probability that if an individual passenger is randomly selected, their weight will be greater than 166 lb.
Assume that weights of passengers are normally distributed with a mean of 177 lb and a standard deviation of 41.4 lb.
Mean = 177
standard deviation = 41.4
We find z-score using given mean and standard deviation
z = 
=
= -0.265700
Probability (z>-0.26570) = 1 - 0.3974 (use normal distribution table)
= 0.6026
P(weight will be greater than 166 lb) = 0.6026
