f(x) = -10
set the equation equal to -10 and solve for x:
-10 = -x-1
Add 1 to both sides:
-9 = -x
Divide both sides by -1:
x = 9
Answer:
the null hypothesis would be: p = 70%/0.7
The alternative hypothesis would be: p < 0.7
Step-by-step explanation:
The null hypothesis is most of the time always the default statement while the alternative hypothesis is tested against the null and is its opposite.
In this case study the null hypothesis would be: the proportion of men who own cats is 70%: p = 0.7
The alternative hypothesis would be: the proportion of men who own cats is smaller than 70% : p < 0.7
Step-by-step explanation:
let d+e=2 be equation 1
let d-e=4 be equation 2
lets make d the subject in equa 1
d = 2-e equation 3
put equation 3 in 2
2-e=4
e=2-4
e=-2
put e=-2 in equa 1
d-2=2
d=4
e is -2 and d is 4

Answer:
C. 
Step-by-step explanation:
The rectangular form of a complex number is represented by the following formula:
(1)
Where each coefficient can be determined as function of the polar components:
(2)
(3)
Where:
- Magnitude of the complex number, dimensionless.
- Direction of the complex number, measured in radians.
If we know that 
and 
, then the rectangular form of the number is:
The rectangular form of 
is . The correct answer is C.
