Answer:
log base 6 of the cube root of 6 matches with 1/3
-3 log 5 of 25 matches with -6
log base 2 of the 4th root of 8 matches with 3/4
log base 3 of 1/81 matches with -4
Answer:
5 1/4
Step-by-step explanation:
For y= -2x + 8 i think y is -2x + 8 and x is 4 - y/2
Answer:
(1). 450 degree and 90 degree.
(2). - 270 degree and - 990 degree.
Step-by-step explanation:
So, we are given the the following data or parameters in this question or problem; A = -630 degree, and we are to look for the next two positive and two negative angles that are coterminal with the given quadrantal angle.
For the positive(+ve) angles we have that;
- 630 degree + 1080 degree = 450 degree; and - 630 degree + 720 degree= 90 degree.
For the negative(-ve) angles we have that;
- 630 degree + 360 degree= - 270 degree and - 630 degree - 360 degree = - 990 degree.
Answer:
Mean of the binomial distribution μ= 6
Variance of the binomial distribution λ² = 4.2
Step-by-step explanation:
<u>Explanation:-</u>
The probability a Gallup poll showed that 30% of Americans are satisfied with the way things are going in the United States.
p = 30% = 0.3
q =1-p = 1- 0.3 =0.7
a sample of 20 Americans is selected as part of a study of the state of the nation
size of the sample 'n' =20
we will use binomial distribution
<u>mean</u>:-
Mean of Americans who are satisfied with the way things are going in the United States (μ) = np
μ= 20 X 0.3
μ= 6
<u>Variance</u>:-
Variance of Americans who are satisfied with the way things are going in the United States λ² = n p q = 20 X(0.3)(0.7)
λ² = 4.2
