Answer:

e=3

Step-by-step explanation:

7(2e-1)-11=6+6e\\14e-7-11=6e+6\\14e-18=6e+6\\8e-18=6\\8e=24\\e=3

That is just one way to get to the answer, but basically just use pemdas, multiplying the parentheses and combining like terms. ;)

According to chebyshev's theorem, at least what percent of the observations lie within plus and minus 1.75 standard deviations o
Alborosie
Chebyshev's theorem in statistics states that for many probability distributions, no more than 1/k² of measured values will be k standard deviations away from the mean.

Because the area under the probability distribution curve is equal to 1, Chebyshev's theorem means that the shaded area shown in the figure is equal to 1 - 1/k².

When k = 1.75, the shaded area is
1 - 1/1.75² = 0.7635 = 67.35%

Therefore the percent of the area within +/- 1.75 standard deviations from the mean is
67.35/2 = 33.7%, which is at least 33% of the observations.

Answer:
According to the Chebyshev theorem, at least 33% of the observations lie within +/- standard deviations from the mean.

What does mean absolute deviation (MAD) measure? Explain how to find the MAD for a set of data.
BigorU [14]
Mean Absolute Deviation is a quantity of measurement that gives you an idea how far, on average, are the data points deviating from the mean. Its equation is

MAD = ∑|x - μ| /  N, where

x is a single data point
μ is the mean of the data set
N is the total number of data points

Suppose, a data set consist of the following: 4, 7, 5, 9, 6, 7, 7, 4. Let's solve first for the mean:

μ = (4+7+5+9+6+7+7+4)/8 = 6.125

Then, the MAD is equal to:

MAD = (|4 - 6.125| + |7 - 6.125| +|5 - 6.125| +|9 - 6.125| +|6 - 6.125| +|7 - 6.125| +|7 - 6.125| +|4 - 6.125|) ÷ 8
MAD = 11/8
MAD = 1.375

Through (2, -1), perp. to y = -2x-3
kramer

9514 1404 393

Answer:

  y = 1/2x -2

Step-by-step explanation:

The given equation is in slope-intercept form, so you recognize its slope is -2. The perpendicular line will have a slope that is the opposite reciprocal of that, so is -1/-2 = 1/2.

The y-intercept can be found from ...

  b = y -mx . . . . . for line of slope m through point (x, y)

  b = -1 -(1/2)(2) = -1 -1 = -2

Then the slope-intercept equation of the perpendicular line is ...

  y = 1/2x -2

Answer:

x = 68

Step-by-step explanation:

If you look at the triangle properly, it is a isosceles triangle where two legs are equal to each other.

The answer for x will be:

56 + 56 + x =180

112 + x = 180

x = 68
