The answer is 5. 
You add all the numbers together then divide by the amount of number there are.
4+2+2+2+5+15=30 
30/6=5

The mean is found by dividing the sum of all terms by the number of terms present in the set.

Set up the equation:

\frac{2 + 2 + 2 + 4 +5 + 15}{6} = \frac{30}{6} = 5

The mean of this sequence is 5.

What is the equation of the polynomial function?
dolphi86 [110]

Answer:

f(x) = (1/2)(x-2)^2(x+1)(x+2)

Step-by-step explanation:

You can determine this by looking at the zeroes of the graph. For any zero that goes through the x-axis, the power of that zero is odd. For any zero that that "bounces" from the x-axis, the power of that zero is even.

Starting from left to right, we can see that the first zero, -2, goes through the x-axis. That means (x+2) is raised to an odd power. The second zero, -1, also goes through, so (x+1) is raised to an odd power. The last zero, 2, bounces off the x-axis, so (x-2) is raised to an even power. The only functions that satisfy this criteria are function 1 and 2.

However, we are not done yet. We need to figure out which multiplier value (1/2, 1/4) is correct. To do this, we plug in 0 for x, since we know that the y-intercept is 4. When we plug in 0, we see that f(0) = 4 for the first function. Therefore, the first function is the answer.

210=157-w<br><br> solve for w
cestrela7 [59]
W=367 because 210+157 is 367 so 367 minus 157 would be 210 so I think w=367. The equation is just written backwards
