Answer:
y = 6x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
y - 5 = 6(x + 1) ← distribute
y - 5 = 6x + 6 ( add 5 to both sides )
y = 6x + 11 ← in slope- intercept form
Answer:
-1 and -11 are x-intercepts, y-intercept = 11.
Step-by-step explanation:
given function: f(x) = x^2 + 12x + 11.
- x-intercepts: value of the function when f(x) is zero.
so, 0= x^2 + 12x + 11.
write 12x as 11x+x,
x^2 + x+11x + 11=0
common terms,
0 = (x + 1)(x+ 11)
- so, -1 and -11 are x-intercepts. because, when we substitute these as x values, the f(x) will be zero.
- y-intercept: value of the function f(x) when x=0 i.e, f(0).
so, y-intercept= 0+0+11 = 11.
Answer:
We are 95% confident that the true proportion of young adults in the population who skip breakfast is between .20 and .27.
Step-by-step explanation:
A 95% confidence interval for the proportion of young adults who skip breakfast is .20 to .27. Which of the following is a correct interpretation of this 95% confidence interval?
We take a sample, and infer for the entire population.
So the interpretation is that we are 95% sure that the true proportion of all young adults who skip breakfast is between 0.20 and 0.27.
So the correct answer is:
We are 95% confident that the true proportion of young adults in the population who skip breakfast is between .20 and .27.
