Answer:
a- Slope-intercept form (y = 
+ 
) ::=> 1
b- Slope of Line = m = 
: From Equation 1
Step-by-step explanation:
a- We have following equation:
7x + 6y = 5
Here if we re-arrange for y:
6y = 5 -7x :: Compare it with y = mx + b
y = +
b-Compare y = mx + b and y = +
m= -7/6 and Slope of lines parallel to the given line is shown in the equation
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
Answer:
16/77 or about 21%
Step-by-step explanation:
P(G,B) = 8/22 x 12/21 = 16/77 (simplified)
Answer:
x = - 6
Step-by-step explanation:
Equation
1/3 * (-9x +12) = 22 Multiply both sides by 3
Solution
3 * 1/3(-9x + 12) = 22*3
- 9x + 12 = 66 Subtract 12 from both sides.
-9x = 66 - 12 Combine
-9x = 54 Divide by -9
x = 54/-9
x = - 6
Answer:
(3×6) -1+4
18+3
