-0.5°C every hour

Step-by-step explanation:as the temperature of the bottom of the mountain changed at 1/5 the rate of temperatures change on the top of the mountain, so, the hourly rate of temperature change at the bottom of the mountain is=

-2.5×(1/5)

=-0.5

Answer:

a. yes

b = 0.0563

c. 0.1460

d. 0.7560

Step-by-step explanation:

a. Yes. n = 10 identical trials with two possible outcomes on each with p = 0.25.

b. p(x= 0) = 10!/(0!*10!)* .250* .7510= 1 * 1 * 0.0563 = 0.0563.

c. p(x= 4) = 10!/(4!*6!)* .254* .756= 210 * .0039 * 0.1780 = 0.1460

d. p(x= 1) = 10!/(1!*9!)* .251* .759= 10 * .25 * 0.0751 = 0.1877

p(x≥ 2) =1 - p(x< 2) = 1 – (0.0563 + 0.1877) =0 .7560

Find the standard form of the equation of the parabola with the given characteristic(s) and vertex at the origin

SpyIntel [72]

The standard form of the equation of the parabola with the given characteristic(s) and vertex at the origin and directrix is y² = 16x.

<h3>What is the parabola?</h3>

It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.

Given that the parabola's vertex is located at the origin and that the directrix is at x = -4, the focus is at (4,0).

Then the equation can be written as

$\rm \sqrt{(x-4)^2 +(y-0)^2} = \sqrt{(x+4)^2 + (y-y)^2}\\\\\sqrt{(x-4)^2 +(y-0)^2} = \sqrt{(x+4)^2}$

On squaring both sides, we have

$\begin{aligned} (x-4)^2 +(y-0)^2 &= (x+4)^2 \\\\x^2 + 16 - 8x +y^2 &= x^2 + 16 + 8x\\\\y^2 &= 16x \end{aligned}$

More about the parabola link is given below.
