What are the scale factor of ABC dilated to XYZ plz help
jekas [21]
<h3>Answer:  B) 2/3</h3>

====================================

Explanation:

The order is important for ABC and XYZ so we can see what letters pair up.

  • A pairs with X since they are the first letters
  • B pairs with Y since they are the second letters
  • C pairs with Z since they are the third letters

Based on that, we can see that AB pairs with XY as they are the first two letters of ABC and XYZ respectively.

Divide the length XY over AB and reduce

XY/AB = 10/15 = 2/3

We could also divide XZ over AC

XZ/AC = 14/21 = 2/3

and we get the same ratio

The miles-per-gallon rating of passenger cars is a normally distributed random variable with a mean of 33.8 mpg and a standard d
EleoNora [17]

Answer:

The probability that a randomly selected passenger car gets more than 37.3 mpg is 0.1587.

Step-by-step explanation:

Let the random variable <em>X</em> represent the miles-per-gallon rating of passenger cars.

It is provided that X\sim N(\mu=33.8,\ \sigma^{2}=3.5^{2}).

Compute the probability that a randomly selected passenger car gets more than 37.3 mpg as follows:

P(X>37.3)=P(\frac{X-\mu}{\sigma}>\frac{37.3-33.8}{3.5})

                   =P(Z>1)\\\\=1-P(Z

Thus, the probability that a randomly selected passenger car gets more than 37.3 mpg is 0.1587.

Convert the following using dimensional analysis:<br><br> 13.2 cm to ft &amp; in
spayn [35]
Multiply (13.2 cm) by (1 inch/2.54 cm). That gives you the whole length in inches. If it's more than 12, then take as many 12s away from it as you can, and call each of those '1 foot'. When you can't take 12 away any more, then what you have left is the inches.
