Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (- 1, 1)
m = = = - 2
Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 → C
Answer: Margin of Error for the given CI is 0.08
Step-by-step explanation:
Given the data in the question;
it is a symmetric class interval hence, sample proportion p = (0.50 + 0.66) / 2
p = 1.16 / 2
sample proportion p = 0.58
Margin of Error E will be;
E = 1/2 × length of Confidence interval
Margin of Error E = 1/2 × ( 0.66 - 0.5)
Margin of Error E = 1/2 × 0.16
Margin of Error E = 0.08
Therefore; Margin of Error for the given CI is 0.08
Answer: 0.135
Step-by-step explanation:
if 54 % of internet users have a wireless connection then number of people that do nor have a wireless connection =46%.
Let A be the event that 54% of internet users have wireless connection.
Let B be the event that 25% of these users that have internet connection use twitter to share updates about themselves.
Hence, probability of A and B happening becomes:
P(AnB) = P(A) * P(B)
P(AnB) = 0.54 * 0.25
P(AnB) = 0.135
The sequence is + 1/4 on each number. So, 1/4, 1/2, 3/4, 1 1/4, etc.
