Vertex is (-2, 0)
y-intercept is 4.
Step-by-step explanation:
to find the function translated 2 units left, we just need to substitute the 'x' in the equation by 'x+2':
f(x) = (x+2)^2 = x2 + 4x + 4
Then, to find the vertex, we can use the formula:
x_v = -b / 2a
x_v = -4 / 2 = -2
Now, finding the y_vertex, we have:
f(x_v) = (-2)^2 + 4*(-2) + 4 = 0
So the vertex is (-2, 0)
To find the y-intercept, we make x = 0 and then find f(x):
f(0) = 0 + 0 + 4 = 4
So the y-intercept is 4.
Ответ:
Given that 44% of all Americans approve of the job the President is doing. The most recent Gallup poll had a sample size of 1400.
Thus, p = 44% = 0.44 and n = 1400.
Mean of a sample distribution of proportions is given by
Part B:
The standard deviation of a sample distribution of proportions is given by:
Part C:
The normal distribution is given by N(mean, standard deviation).
Given from part A, that the mean of the distribution is 616, and from part B, that the standard deviation of the distribution is 18.57. The normal approximation of the distribution is given by N(616, 18.57).
A normally distributed distribution with a mean of 616 and a standard deviation of 18.57.
Part D:
The probability that the Gallup poll will come up with a probability within three percentage points of the true 44% is given by:
The standardization of the sample distribution of proportions is given by:
