Find the x-intercept for the line represented by this equation. y=5x-2
1 answer:
Answer:
C
Step-by-step explanation:
The x- intercept is where the line crosses the x- axis. At this point on the x- axis the y- coordinate is zero.
To find the x- intercept let y = 0 in the equation and solve for x, that is
5x - 2 = 0 ( add 2 to both sides )
5x = 2 ( divide both sides by 5 )
x = ← x- intercept
coordinates of x- intercept are (, 0 ) → C

Answer:
The mean of the sampling distribution of p is 0.75 and the standard deviation is 0.0306.
Step-by-step explanation:
Central Limit Theorem:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
