Please help me answer these 2 questions

1 answer:

4 0

The first one is not a question. Rather it is the parameters in which the second question exists.

2.

49.85%

This is because the likelihood of a point being within 2 SDs of the mean is 99.7%. This leaves .15 above and .15 below that curve. Given that we are looking from the mean (50%) and the upper limit with the exception of that .15, we would get the answer above.

Stolb23 [73]

Answer:

v=a+ 2e1= [3 1 1 1] $x^{T}$ .

Step-by-step explanation:

Let a = $^{}$ $\left[\begin{array}{ccc}\\1&1&1\\\end{array}\right] ^{T}$ and we know that $\alpha$ =±║α║₂= 2.

As we have gone over in class, the formula for v is v= a- $\alpha$ e1

with the sign of chosen to avoid subtraction. This gives v=a+ 2e1= [3 1 1 1] $x^{T}$ .

Question:

Determine the Householder transformation that annihilates all but the first entry of the vector[1 1 1 1]>Specifically, if

$I-2vv^{T}/v^{T}v\left[\begin{array}{ccc}1\\1\\1\\1\end{array}\right]$ == $\left[\begin{array}{ccc}\alpha \\0\\0\\0\end{array}\right]$

what are the values of α and v?

Answer:

temperature is decreasing as time passes
x-axis
hot drink temperature (°C)

Step-by-step explanation:

1. Each value of temperature is lower than the one previous, so we can say the temperature is decreasing. We also notice that the rate of decrease is getting smaller, possibly because the temperature is approaching a horizontal asymptote.

2. The horizontal axis, where temperature is plotted, is conventionally called the x-axis.

3. The label on the vertical axis is "temperature" and the graph title is "cooling a hot drink ...", so we presume the dependent variable is the temperature of a hot drink.

Lines AD and BC are parallel.

allochka39001 [22]

*see attachment for the missing figure

Answer:

Angle ADE = 45°

Angle DAE = 30°

Angle DEA = 105°

Step-by-step explanation:

Since lines AD and BC are parallel, therefore:

Given that angle Angle CBE = 45°,

Angle ADE = Angle CBE (alternate interior angles are congruent)

Angle ADE = 45° (Substitution)

Angle DAE = Angle ACB (Alternate Interior Angles are congruent)

Angle ACB = 180 - 150 (angles on a straight line theorem)

Angle ACB = 30°

Since angle DAE = angle ACB, therefore:

Angle DAE = 30°

Angle DEA = 180 - (angle ADE + angle DAE) (Sum of angles in a triangle)

Angle DEA = 180 - (45 + 30) (Substitution)

Angle DEA = 180 - 75

Angle DEA = 105°
