Answer:

To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. ... Divide the sum of the absolute values of the differences by the number of data values.

Sample Answer: First, find the mean of the data set by averaging. Next, find the absolute deviations for each data point. That is, find the distance each point is from the mean. Then find the mean of the absolute deviations.

Masja [62]

Answer:

(b) 0.251

Step-by-step explanation:

1. Standard deviation equation:

$SD=\sqrt{\frac{\sum\limits^N_i {(x_{i}-X)^{2} } }{N} }$

Where X is the mean of the data, and N the amount of data. Then, N=5

2. Estimate the Mean:

$X=\frac{0.750+0.750+0.200+0.600+0.200}{5}=\frac{2.5}{5}=0.5\\$

3. Caclulate Standard deviation:

$SD=\sqrt{\frac{{(0.750-0.500)^{2}+(0.750-0.500)^{2}+(0.200-0.500)^{2}+(0.600-0.500)^{2}+(0.200-0.500)^{2} } }{5} }$

$SD=\sqrt{\frac{0.315}{5} }=\sqrt{0.063}\\SD=0.251$

Tanzania [10]

Answer:

$\boxed{\bold{One \ Solution}}$

Step-by-step explanation:

<u>Solve equation to find answer(s)</u>

<u></u>

Combine: 6z - 3z = 3z

$\bold{3z-7=-2+3}$

Add: -2 + 3 = 1

$\bold{3z-7=1}$

Add 7 to both sides:

$\bold{3z-7+7=1+7}$

Simplify:

$\bold{3z=8}$

Divide both sides by 3:

$\bold{\frac{3z}{3}=\frac{8}{3}}$

Simplify:

$\bold{z=\frac{8}{3}}$

Can someone please help me with part b?

gogolik [260]

Answer:

x-intercept(s): (-2, 0), (6, 0)

y-intercept(s): (0, -6)

Step-by-step explanation:

An x-intercept represents the point(s) at which the parabola intersects the x axis. A parabola can have 0, 1, or 2 x-intercepts.

A y-intercept represents the point at which the parabola intersects the y axis. A parabola always has exactly 1 y-intercept.

Hope it helps :) and let me know if you're still confused.
