URGENT!!! Which is a y-intercept of the graphed function?

dexar [7]

The y-intercept is where the graph goes through the y-axis (the vertical line in the center). It goes through at y=-9, so the coordinates would be (0,-9), since it is (x,y).

Does anyone know this one?

butalik [34]

Answer:

Step-by-step explanation:

For the lines to be parallel, then the 2 given angles are alternate and congruent, thus

15x - 46 = 9x + 8 ( subtract 9x from both sides )

6x - 46 = 8 ( add 46 to both sides )

6x = 54 ( divide both sides by 6 )

x = 9 → C

Suppose that distribution of the daily calcium intake of Americans is left skewed with a mean of 800 mg and a standard deviation

babymother [125]

Answer:

Explained below.

Step-by-step explanation:

According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normal.

Then, the mean of the sampling distribution of sample means is given by,

$\mu_{\bar x}=\mu$

And the standard deviation of the sampling distribution of sample means is given by,

$\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}$

So, if the sample of daily calcium intake of Americans collected is more than 30, then the sampling distribution of $\bar X$ will be approximately normal.
