How does the multiplicity of a zero determine the behavior of the graph at that zero?

grin007 [14]

If the graph crosses the x-axis and appears almost linear at the intercept, it is a single zero. If the graph touches the x-axis and bounces off of the axis, it is a zero with even multiplicity. If the graph crosses the x-axis at a zero, it is a zero with odd multiplicity. The sum of the multiplicities is the degree

Line ab contains the points a(-2,3) and b(4,5). Line ab has a slope that is

gayaneshka [121]

Given two points $A = (A_x, A_y),\ B = (B_x,B_y)$ , the slope of the line passing through the two points is

$m = \dfrac{A_y-B_y}{A_x-B_x}$

So, in your case, you have

$m = \dfrac{3-5}{-2-4} = \dfrac{-2}{-6} = \dfrac{1}{3}$

A line passes through (10,5) and (13,-4). Write the equation of the line in standard form.

nexus9112 [7]

Using two point form
y-5/-4-5=x-10/13-10
rearrange to get 3x+y-35=0

Answer:

The margin of error that corresponds to a 95% confidence interval is 4.96.

Step-by-step explanation:

We have the standard error(which is the same as the standard deviation of the sample), so we use the students t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. There are 6 days, so

df = 6 - 1 = 5

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 35 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.95}{2} = 0.975([tex]t_{0.975}$ ). So we have T = 2.5706

The margin of error is:

M = T*s = 2.5706*1.93 = 4.96

The margin of error that corresponds to a 95% confidence interval is 4.96.
