Suppose that X is a random variable with probability function x 0 1 2 3 4 5 P(x) 0.00032 0.0064 0.0512 0.2048 0.4096 0.32768 and that the random variable Y = 9X2 − 36X + 4. (a) What is the range of Y ? (b) Calculate P{Y = 4}. (c) Calculate P{Y = 0}.

Answers

(a) For each value of X we have:

X=0\quad\Rightarrow\quad Y=4\n\nX=1\quad\Rightarrow\quad Y=-23\n\nX=2\quad\Rightarrow\quad Y=-32\n\nX=3\quad\Rightarrow\quad Y=-23\n\nX=4\quad\Rightarrow\quad Y=4\n\nX=5\quad\Rightarrow\quad Y=49

so the range of Y = {-32, -23, 4, 49}

(b)

P\{Y=4\}=P\{X=0\}+P\{X=4\}=0.00032+0.4096=\boxed{0.40992}

(c)

Y cannot equal 0, so

P\{Y=0\}=0

The 3rd degree Taylor polynomial for cos(x) centered at a = π 2 is given by, cos(x) = − (x − π/2) + 1/6 (x − π/2)3 + R3(x). Using this, estimate cos(86°) correct to five decimal places.

Answers

Answer:

The cosine of 86º is approximately 0.06976.

Step-by-step explanation:

The third degree Taylor polynomial for the cosine function centered at a = (\pi)/(2) is:

\cos x \approx -\left(x-(\pi)/(2) \right)+(1)/(6)\cdot \left(x-(\pi)/(2) \right)^(3)

The value of 86º in radians is:

86^(\circ) = (86^(\circ))/(180^(\circ))* \pi

86^(\circ) = (43)/(90)\pi\,rad

Then, the cosine of 86º is:

\cos 86^(\circ) \approx -\left((43)/(90)\pi-(\pi)/(2)\right)+(1)/(6)\cdot \left((43)/(90)\pi-(\pi)/(2)\right)^(3)

\cos 86^(\circ) \approx 0.06976

The cosine of 86º is approximately 0.06976.

Final answer:

We estimate the cosine of 86 degrees by first converting 86 degrees to radians (approximately 1.50098) and substituting this into the Taylor polynomial. The result is -0.08716

Explanation:

To calculate the cosine of 86 degrees using the Taylor polynomial, we first have to convert the degrees to radians, as the Taylor polynomial is based on the radian definition. The conversion yields approximately 1.50098 radians.

Then, we substitute this value into the Taylor polynomial. We ignore R3(x) as it represents the remainder and tends to zero as x approaches π/2. So, cos(86°) ≈ - (1.50098 - π/2) + 1/6 * (1.50098 - π/2)³. Computing this gives us an estimate of cos(86°) = -0.08716 to five decimal places.

Answers

Assuming that this particular type of question is a system of equations one. More specifically linear equations, you would simply substitute one of the equations into the other one. Then upon doing so, plug in the x and y coordinates for the point into the x and y variables of the equation and then see if it is a solution, by checking if the left hand side of the equation equals that of the right hand side of the equation.
