Which figures demonstrate a translation?

tensa zangetsu [6.8K]

The two bottom graphs demonstrate translations.

<h3>Which figures demonstrate a translation?</h3>

We will have a translation only if:

The size of the figure does not change (like in option 1, which we can discard).
If the "direction" of the figure does not change, like in option 2, where you can see that there is a reflection.

The images where the figures are only moved a little bit are the ones that demonstrate just a translation, and these are the two lower ones.

Find the slope of the graphed line

Anna [14]

Answer:

Step-by-step explanation:

Pick two points on the line

(0,-5) and (1,-1)

We can find the slope using

m = (y2-y1)/(x2-x1)

= ( -1 - -5)/(1 - 0)

(-1+5)/(1-0)

Suppose that the travel time from your home to your office is normallydistributed with mean 40 minutes and standard deviation 7

Alex73 [517]

Answer:

The latest time that you should leave home is 12:08 PM

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 40, \sigma = 7$

If you want tobe 95 percent certain that you will not be late for an office appointment at 1 P.M.,what is the latest time that you should leave home?

How many minutes is the 95th percentile of travel time?

it is X when Z has a pvalue of 0.95. So it is X when Z = 1.645. So

$Z = \frac{X - \mu}{\sigma}$

$1.645 = \frac{X - 40}{7}$

$X - 40 = 7*1.645$

$X = 51.6$

Rouding up, the 95th percentile for travel time is 52 minutes.

52 minutes before 1PM is 12:08 PM.

The latest time that you should leave home is 12:08 PM
