The Chebyshev Theorem guarantees that we will find at least 75% of the people with wages between $9.25 and $14.25.

<h3>What does Chebyshev’s Theorem state?</h3>

When the distribution is not normal, Chebyshev's Theorem is used. It states that:

  • At least 75% of the measures are within 2 standard deviations of the mean.
  • At least 89% of the measures are within 3 standard deviations of the mean.
  • An in general terms, the percentage of measures within k standard deviations of the mean is given by 100(1 - \frac{1}{k^{2}}).

The Chebyshev Theorem guarantees that we will find at least 75% of the people with wages within 2 standard deviations of the mean, hence the bounds are:

  • 11.75 - 2 x 1.25 = $9.25.
  • 11.75 + 2 x 1.25 = $14.25.

PIT_PIT [208]

Answer:

p(t) = 0 for t = 1

p(t) = 1 for t = 1/8 = 8^-1

Step-by-step explanation:

the graph you will have to do yourself.

just go there and type in

-  log_{8}(x)

well, don't type "log" in letters.

you start by typing the "-" sign, and then you need to look up the functions by clicking on the "funcs" button and look for the log functions .

pick the

log_{a}

option. and then simply enter 8 as the first parameter in the {} brackets and x as the second in the () brackets.

and then you see.

any logarithm is 0 for x (or t) = 1.

because any a⁰ = 1.

and the logarithm gives you that exponent of the base number that leads to the given x value.

in other words : a logarithm is the inverse function of an exponential function.

the exponential function is

y = a^x

and the logarithm then determines

x =  log_{a}(y)

that is all.

and

-  log_{8}(x)  = 1

means that the logarithm itself delivered -1.

and 8^-1 = 1/8

so, p(t) = 1 for t = 1/8

PLEASEEEE HELPPPPP!!!
Taya2010 [7]

(1, 3.5 ) and (3, 3.5 )

the endpoints of the midsegment are at the midpoints of DE and DF

using the midpoint formula with D(0, 7), E(2, 0), F(6, 0)

midpoint of DE = [\frac{1}{2}(0 + 2),\frac{1}{2}(7 + 0)] = (1, 3.5)

midpoint of DF = [\frac{1}{2}(0 + 6),\frac{1}{2}(7 + 0)] = (3, 3.5)
