Answer:

<h2>2.1 times the MAD</h2>

Step-by-step explanation:

Data Set A has a mean of 67  

Data Set B has a mean of 92.

The MAD of each data set is 12

Express the difference in the measures of center as a multiple of the measure of variation.

We find the difference of mean and divide by MAD

<h3><u>Data set B-Data set A</u></h3><h3>           MAD</h3><h3 /><h3><u>92-67</u></h3><h3>   12</h3><h3> = 2.0833</h3>

<h3>So, the difference in the means is about 2.1 times the MAD</h3>

5 Show different ways to make 492,623.
timama [110]

Step-by-step explanation:

Start by writing 492,623 in standard form

4 hundred thousands + 9 ten thousands + 2 thousands + 6 hundreds + 2 tens + 3 ones

We can write this in other ways by moving a digit to the next smaller place value.  For example, we move the 4 one place to the right to get 49 ten thousands:

49 ten thousands + 2 thousands + 6 hundreds + 2 tens + 3 ones

Then, we can move the 49 ten thousands to the right to get 492 thousands, and we can move 6 hundreds to the right to get 62 tens.

492 thousands + 62 tens + 3 ones

Or, we can do this:

4926 hundreds + 23 ones

Let c be the curve of intersection of the parabolic cylinder x2 = 2y, and the surface 3z = xy. find the exact length of c from t
Mandarinka [93]
Parameterize the intersection by setting x(t)=t, so that

x^2=2y\iff y=\dfrac{x^2}2\implies y(t)=\dfrac{t^2}2
3z=xy\iff z=\dfrac{xy}3\implies z(t)=\dfrac{t^3}6

The length of the path C is then given by the line integral along C,

\displaystyle\int_C\mathrm dS

where \mathrm dS=\sqrt{\left(\dfrac{\mathrm dx}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dy}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dz}{\mathrm dt}\right)^2}\,\mathrm dt. We have

\dfrac{\mathrm dx}{\mathrm dt}=1
\dfrac{\mathrm dy}{\mathrm dt}=t
\dfrac{\mathrm dz}{\mathrm dt}=\dfrac{t^2}2

and so the line integral is

\displaystyle\int_{t=0}^{t=2}\sqrt{1^2+t^2+\dfrac{t^4}4}\,\mathrm dt

This result is fortuitous, since we can write

1+t^2+\dfrac{t^4}4=\dfrac14(t^4+4t^2+4)=\dfrac{(t^2+2)^2}4=\left(\dfrac{t^2+2}2\right)^2

and so the integral reduces to

\displaystyle\int_{t=0}^{t=2}\frac{t^2+2}2\,\mathrm dt=\dfrac{10}3

Let an integer be chosen at random from the integers 1 to 30 inclusive. Find the probability that the integer chosen is not even
mylen [45]
Well since the pattern is odd, even, odd, even you are just as likley to pull on odd (<span>not evenly divisible by 2) numebr as an even number, so the option is C.

A race car driver is doing a time trial of a new car on a straight track. The car's distance from the timekeeper is represented
Fittoniya [83]

Answer:

The distance at which the timekeeper is the race car at the start is 50 feet.

Step-by-step explanation:

You know that the car's distance from the timekeeper is represented by

y=293*x +50

where x is time in seconds and y is distance in feet from the timekeeper's position.

You want to determine how far the timekeeper is from the race car at the start. That is, the distance the timekeeper is from the car when the time is equal to zero.  This indicates that x = 0. Replacing x by that value in the expression of the distance of the car from the timekeeper as a function of time and solving:

y=293*0 +50

you get:

y=50

<u><em>The distance at which the timekeeper is the race car at the start is 50 feet.</em></u>
