Answer:

The boy is faster

Step-by-step explanation

formula from minutes per second to km/h

  X x 3600/1000

 4.4 x 3600/1000=15.84 km/h is slower than 16 km/h

Find the limit, if it exists, or type dne if it does not exist.
Phantasy [73]
\displaystyle\lim_{(x,y)\to(0,0)}\frac{\left(x+23y)^2}{x^2+529y^2}

Suppose we choose a path along the x-axis, so that y=0:

\displaystyle\lim_{x\to0}\frac{x^2}{x^2}=\lim_{x\to0}1=1

On the other hand, let's consider an arbitrary line through the origin, y=kx:

\displaystyle\lim_{x\to0}\frac{(x+23kx)^2}{x^2+529(kx)^2}=\lim_{x\to0}\frac{(23k+1)^2x^2}{(529k^2+1)x^2}=\lim_{x\to0}\frac{(23k+1)^2}{529k^2+1}=\dfrac{(23k+1)^2}{529k^2+1}

The value of the limit then depends on k, which means the limit is not the same across all possible paths toward the origin, and so the limit does not exist.

Find the t-value such that the area in the right tail is 0.005 with 28 degrees of freedom.
klasskru [66]

Answer:

t = 3.673900

Step-by-step explanation:

Given

df = 28 -- degree of freedom

Area = 0.005

Required

Determine the t-value

The given parameters can be illustrated as follows:

P(T > t) = \alpha

Where

\alpha = 0.005

So, we have:

P(T>t) = 0.005

To solve further, we make use of the attached the student's t distribution table.

From the attached table,

The t-value is given at the row with df = 28 and \alpha = 0.005 is 3.673900

Hence, t = 3.673900

Answer:

<h2>16.26</h2>

Step-by-step explanation:

Pythagorean Theorem | a^2 + b^2 = c^2

1) Plug in a & b

<h2>11^2 + 12^2 = c^2</h2>

2) Rewrite

<h2>c = \sqrt{11^2 + 12^2}</h2>

3) Solve

<h2>c = 16.2788206</h2>

4) Round
