Solve for x please help

Fed [463]

Answer:

x = 5

Step-by-step explanation:

By remote exterior angle theorem:

$(6 + 25x) \degree = (18x - 3)\degree + 44\degree \\ 6 + 25x = 18x - 3 + 44 \\ 25x - 18x = 41 - 6 \\ 7x = 35 \\ x = \frac{35}{7} \\ \huge \red{ \boxed{ x = 5}}$

May anyone help me i have no idea

shtirl [24]

Answer:

No. GCF = 2

$2(x^2 - 5x + 10)$

$2(x^2 - 5x + 10)$ $(\dfrac{-5}{2})^2=(-2.5)^2 =6.25$

$2[x^2 - 5x+6.25-6.25 + 10]$

$2[(x^2 - 5x+6.25)-6.25 + 10]$

$2[(x - 2.5)^2-6.25+ 10]$

$2[(x - 2.5)^2+3.75]$

$2(x - 2.5)^2+7.5$

The mean score on a driving exam for a group of driver's education students is 84 points, with a standard deviation of 4 points.

Anastasy [175]

Using Chebyshev's Theorem, it is found that:

At least 75% of the exam scores fall between 76 and 92.

---------------------------

Chebyshev's Theorem states that the percentage of measures within k standard deviations of the mean is of at least $100(1 - \frac{1}{k^{2}})$ .

With k = 2, that is, within 2 standard deviations of the mean:

$P = 100(1 - \frac{1}{2^{2}})$

$P = 100(1 - \frac{1}{4})$

$P = 100(\frac{3}{4})$

$P = 75$

At least 75% of the measures are within 2 standard deviations of the mean.

84 - 2(4) = 76

84 + 2(4) = 92

Thus, at least 75% of scores between 76 and 92.
