<em>5 to the 2nd power times 5 to the 2nd power is equivalent to 625</em>

<h2>Explanation:</h2>

In this case, we have the following statement:

<em>5 to the 2nd power times 5 to the 2nd power. </em>In a mathematical language:

5^2\times 5^2

From product rules, we know that:

a^n \cdot a^m=a^{n+m}

Applying this rule to our problem:

5^2\times 5^2=5^{2+2}=5^4=625

<em>5 to the 2nd power times 5 to the 2nd power is equivalent to 625</em>

Two hikers, Charles and Maria, begin at the same location and travel in perpendicular directions. Charles travels due north at a
attashe74 [19]

Answer:

d(L)/dt   = 9,43 miles per hour

Step-by-step explanation:

As Charles and Maria travel in perpendicular directions, these directions could be considered as two legs ( x and y ) of a right triangle and distance (L)  between them as the hypotenuse, therefore, according to Pythagoras theorem

L²  = x² + y²

And as all ( L , x , and y ) are function of time, we apply differentiation in both sides of the equation to get

2* L d(L)/dt   =  2*x*d(x)/dt  + 2*y*d(y)/dt      (1)

In equation (1) we know:

d(x)/dt  =  8 miles/per hour     ( Maria )

d(y)/dt  =  5  miles /per hour   (Charles)

In 3 hours time   Maria has travel  3*8  = 24 miles

And  Charles   5*3  = 15 miles

Then at that time L is equal to

L  = √ 24² +  15²    ⇒  L  =  √ 576 + 225   ⇒ L = √801     ⇒ L =28,30 miles

Then plugging these values  in equation (1)

2* L d(L)/dt   =  2*x*d(x)/dt  + 2*y*d(y)/dt

2* 28.30 * d(L)/dt  = 2*24*8  + 2* 15*5

56.6 *d(L)/dt   =  384  +  150

d(L)/dt   = 534/56,6

d(L)/dt   = 9,43 miles per hour

The total scores on the Medical College Admission Test (MCAT) in 2013 follow a Normal distribution with mean 25.3 and standard d
Elden [556K]
In a normal distribution, the median is the same as the mean (25.3). The first quartile is the value of Q_1 such that

\mathbb P(X

You have

\mathbb P(X

For the standard normal distribution, the first quartile is about z\approx-0.6745, and by symmetry the third quartile would be z\approx0.6745. In terms of the MCAT score distribution, these values are

\dfrac{Q_1-25.3}{6.5}=-0.6745\implies Q_1\approx20.9
\dfrac{Q_3-25.3}{6.5}=0.6745\implies Q_3\approx29.7

The interquartile range (IQR) is just the difference between the two quartiles, so the IQR is about 8.8.

The central 80% of the scores have z-scores \pm z such that

\mathbb P(-z

That leaves 10% on either side of this range, which means

\underbrace{\mathbb P(-z

You have

\mathbb P(Z

Converting to MCAT scores,

-1.2816=\dfrac{x_{\text{low}}-25.3}{6.5}\implies x_{\text{low}}\approx17.0
1.2816=\dfrac{x_{\text{high}}-25.3}{6.5}\implies x_{\text{high}}\approx33.6

So the interval that contains the central 80% is (17.0,33.6) (give or take).

Answer I’ll give u brain thingy
Zanzabum

Answer:

It means that for every 1 unit of time, the equation shows an increase of 8.38 units of distance.

Step-by-step explanation:

Slope is \frac{rise}{run}. Any number that does not have a denominator technically has a denominator of 1. Therefore, your slope is actually \frac{8.38}{1}. That means you have a rise, or the vertical progression, of 8.38 while your run, or your horizontal progression, is 1. For every unit your line travels horizontally, it travels 8.38 units vertically. I hope this makes sense.
