Factor the following polynomial completely.<br> -x2 y2 + x4 + 4y 2

Which expressions are equivalent to the one below? Check all that apply. log7 1• log5 25

ELEN [110]

Answer:

D

Step-by-step explanation:

Use logarithms properties:

$\log_a1=0\\ \\\log_aa=1\\ \\\log_ab^k=k\log_ab$

Now,

$\log_71=0\\ \\\log_525=\log_55^2=2\log_55=2\cdot 1=2$

and

$\log_71\cdot \log_525=0\cdot 2=0$

Hence, correct option is option D.

Louis started a table showing a multiplication patterns complete the table describe a pattern you see in the products

kvasek [131]

One pattern that you can see in a multiplication table is the perfect square numbers. It runs from the top left hand corner directly through the middle to the bottom right hand corner. A perfect square is a number that is multiplied by itself. The perfect square numbers are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144. They keep going forever on but those are the main ones from 1x1 to 12x12.

Answer: <u>Last option</u>

$Z_ {13} = 0.5,\ Z_ {17} = 2.5$

Step-by-step explanation:

The z-scores give us information about how many standard deviations from the mean the data are. This difference can be negative, if the data are n deviations to the left of the mean, or it can be positive if the data are n deviations to the right of the mean.

To calculate the Z scores, we calculate the difference between the value of the data and the mean and then divide this difference by the standard deviation.

so

$Z = \frac{x- \mu}{\sigma}$ .
