Answer:

Step-by-step explanation:

(-4,2) ; (4,-5)

$Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-5-2}{4-[-4]}\\\\=\frac{-7}{4+4}\\\\=\frac{-7}{8}$

m = -7/8 ; (-4,2)

equation: y - y1 = m(x - x1)

$y-2=\frac{-7}{8}(x-[-4])\\\\y-2=\frac{-7}{8}(x+4)\\\\y-2=\frac{-7}{8}x +\frac{-7}{8}*4\\\\y=\frac{-7}{8}x-\frac{7}{2}+2\\\\y=\frac{-7}{8}x-\frac{7}{2}+\frac{4}{2}\\\\y=\frac{-7}{8}x-\frac{3}{2}\\$

Give a real world example of a sample that was used to make a prediction about a population

olchik [2.2K]

Answer:

Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.

Find the value of x.

miskamm [114]

Answer:

Step-by-step explanation:

Since we have two secants,

Use this theorem,

When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.

In other words,

$x + 18 = \frac{130 - 4x + 22}{2}$

$2x + 36 = 130 - 4x + 22$

$2x + 36 = 108- 4x$

$6x + 36 = 108$

$6x = 72$

$x = 12$

B is our answer
