Since the two trapezoids are similar, you could solve by doing a proportion: 12/20=X/25

Which expression can be used to find the slope of a line containing the points (–3, 2) and (7, –1)?
ArbitrLikvidat [17]

When 2 points are given, you would use the point slope formula.  y-yo = m(x-xo). You may also use a different formula.  P1 (x , y) and P2 (z , h)

then slope of line = ( h - y)/ (z - x)

so, apply this formula here also

slope of line = (-1-2)/(7- {-3})

                       (-3)/(10)

Where yo = either of the 2 point y coordinates

          xo = either of the 2 point x coordinates (paired with the above point)

          m = the slope

In this case,  m = (-1-2)/(7+3) = -3/10

Using point 1,

                            y-2 = (-3/10)(x+3) = (-3/10)x -9/10 or        y = (-3/10)x + 11/10

How would you "remove the discontinuity" of f? In other words, how would you define f(5) in order to make f continuous at 5? f(x
satela [25.4K]

Given f(x) = [(x^2 -2x -15)/x-5], notice it is a rational function

But the numerator x^2 -2x -15 could be factored, which yields

(x – 5)(x + 3)

Therefore f(x) = (x – 5)(x + 3)/ (x-5)

Cancelling x-5, f(x)  = x + 3

In this way, the f(x) is continuous at any point, and is basically a line.

Suppose we are making predictions of the dependent variable y for specific values of the independent variable x using a simple l
e-lub [12.9K]

Answer:

width (C.I) ∠ width (P.I)

Step-by-step explanation:

In statistics, a confidence interval (C.I) is known as an interval estimate which is computed using the observed data that might contain the actual value of an unknown parameter. The confidence level is commonly used for estimation before examining the actual data. On the other hand, the prediction interval (P.I) is a range of values that calculate the value of a new observation by considering the existing model developed using the actual data. Therefore, the true statement is:

width (C.I) ∠ width (P.I)
