Answer:
$28
Step-by-step explanation:
Given:
data = [22,30,35,25,25,20,27]
For eight night, the new list is:
new_data = [22,30,35,25,25,20,27,x]
Mean = 26.50
Mean Formula:
Therefore:
Multiply both sides by 8:
Solve for x:
Subtract 184 both sides:
Therefore, she will earn $28 in eighth night
The attachment below is the result of combining all eighth data as we get 26.5 through python language with numpy package.
Answer:
<h2>6cis120°</h2>Step-by-step explanation:
The general form of a complex number z = x+iy
If x = rcos and y = rsin
where r is the modulus of the complex number and is the argument, z in polar form is represented as:
z = rcos+ rsin
z = r(cos+ isin
)
z = rcis
Given the complex number z=−3+3√3i
r =
since the argument is negative and tan is negative in the 2nd and 4th quadrant,
In the second quadrant, theta = 180- 60 = 120°
On substituting r and theta, the complex number in polar form is expressed as 6cis120°
