Answer

-2v+8 (1+2v)=-90 then V = -7

Step-by-step explanation:

-2v + 8 x (1 + 2v) = -90

-2v + 8 + 16v = -90

14v + 8 = -90

14v = -98  

V = -98/14

V= -7

Hope this helps ;)

Both sets of values have an average of 13. Is Set A's standard deviation smaller, larger, or about the same as Set B's? (Note: T
Softa [21]

Answer:

  Set A's standard deviation is larger than Set B's

Step-by-step explanation:

Standard deviation is a measure of variation. One way to judge the value of standard deviation is by looking at the range of the data. In general, a dataset with a smaller range will have a smaller standard deviation.

The range of data Set A is 25-1 = 24.

The range of data Set B is 18-8 = 10.

Set A's range is larger, so we expect its standard deviation to be larger.

__

The standard deviation is the root of the mean of the squares of the differences from the mean. In Set A, the differences are ±12, ±11, ±10. In Set B, the differences are ±5, ±3, ±1. We don't actually need to compute the RMS difference to see that it is larger for Set A.

Set A's standard deviation is larger than Set B's.

A sweater that regularly sold for $52 id now on sale at 30% off. what is the sale price?
pochemuha

Since the sweater is now 30% off, that means it is selling for 70% of it's original price ( 100% - 30% = 70%).


Multiply the original price by 70%:


52 x 0.70 = 36.40


The sale price is $36.40
