Why is the image of a figure after a translation is congruent to its preimage

zaharov [31]

"Translation" means "move it to a different place".

When you buy a hula-hoop or a frisbee and take it home from the store,
its shape doesn't change. And when you leave home in the morning and
move yourself to school, your shape and size don't change.

Translation does not change the shape or the size of a figure. All of its
sides and angles are still the same as they were in the original location.
Wherever it may go, it's still congruent to the picture of it that you took
before it moved.

In a finance class, the final grade is based on three tests. Historically, the instructor tells the class that the joint probabi

Greeley [361]

Answer:

0.5556 or 55.56%

Step-by-step explanation:

If the probability of getting an A in both tests, P(B), is 0.5, and the probability of getting an A in the first test, P(F), is 0.9, then the probability of getting an A on the second test, P(S) is:

$P(B) = P(F)*P(S)\\0.5=0.9* P(S)\\P(S) = 0.5556=55.56\%$

Given that a student has scored an A on the first test, the probability that the student will score an A on the second test is 0.5556 or 55.56%

The profits of life insurance companies A and B are normally distributed with the same mean. The variance of company B's profit

Lerok [7]

Answer:

23.58-th

Step-by-step explanation:

The standard deviation of company B's profit is:

$\sigma_B=\sqrt{2.25}\sigma_A$

Let X be the profit correspondent to the 14th percentile of company A's profit.

The z-score for 14th percentile of a normal distribution is roughly -1.08.

The z-scores for X in companies A and B are:

$-1.08 = \frac{X-\mu}{\sigma_a} \\z_B = \frac{X-\mu}{\sqrt{2.25}*\sigma_a}\\z_B=\frac{-1.08}{\sqrt{2.25}}\\z_B = -0.72$

The z-score for X in company B's profit distribution is -0.72, which corresponds to the 23.58-th percentile.
