<h3>Answer: SSS</h3>

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

Explanation:

The left slanted side of the smaller triangle is 2 units long. The left slanted side of the larger triangle is 2+2 = 4 units long. The jump from small to large is "times 2".

The same applies when focusing on the right slanted sides for each triangle.

The horizontal pieces also have this same rule applied when going from 4 to 8.

Therefore, the larger triangle's sides are twice as long compared to the smaller triangle's sides.

This is another way of saying that the ratio large/small is equal to 2, and why the SSS similarity theorem works here.

The length of time it takes to find a parking space at 9 A.M. follows a normal distribution with a mean of 5 minutes and a stand

erastovalidia [21]

Answer:

$z=0.524$

And if we solve for a we got

$a=5 +0.524*2=6.048 \approx 6.05 min$

Step-by-step explanation:

Let X the random variable that represent the lenght time it takes to find a parking space at 9AM of a population, and for this case we know the distribution for X is given by:

$X \sim N(5,2)$

Where $\mu=5$ and $\sigma=2$

For this part we want to find a value a, such that we satisfy this condition:

$P(X>a)=0.3$ (a)

$P(X$ (b)

As we can see on the figure attached the z value that satisfy the condition with 0.7 of the area on the left and 0.3 of the area on the right it's z=0.524

If we use condition (b) from previous we have this:

$P(X$
