Answer:

<h2>25 months</h2>

Step-by-step explanation:

Using the formula for calculating the standard error of the mean to get the standard deviation. The standard error of the mean is expressed as;

SE = S/√n where;

S is the standard deviation

n is the sample size

Given SE = 25 months and n = 1, on substituting this parameters into the formula, we will have;

25 = S/√1

25 = S/1

cross multiply

S = 25*1

S = 25 months

<em>Hence the standard deviation based on the sample is 25 months</em>

Answer:

n \geq  -\frac{-29}{28}

Step-by-step explanation:

-3(1 - 7n) \geq  -32 - 8n\\-3 + 21n \geq  -32 -8n\\

       +8n               +8n

-3 + 28n \geq  -32\\+3                      +3\\28n  \geq  -29\\/28              /28\\n \geq \frac{-29}{28}

Use the graph of the function to find f(-2)
lesya692 [45]

Answer:

Answer D:  f(-2) = 2

Step-by-step explanation:

To evaluate f(-2) we need to find what is the y-value that the graph shows for the x-value "-2".

To find such, we look for the value x = -2 on the horizontal (x) axis (located two units to the left of the origin of coordinates (0,0)), and from there, we investigate at what y-value (value on the vertical y-axis) a line that follows the vertical grid passing through x = -2, intercepts the graph of the function.

That is pictured with a red dot in the attached image. Notice that the y-value at which such intersection occurs is y = 2.

Therefore f(-2) = 2
