weqwewe [10]3 years ago
6 0

Answer:

2=k^1/x

3=k^1/y

12=k^1/z.......we get...

(atq)------k^1/x=k^1/y=k^1/z

(*a^m=b^m......b=a)

~1/x=1/y=1/z

1/z=1/y+1/x×2

(12=3+2×2)

1/z=1/y+2/x.....proved

What is the opposite of the number 14​
lidiya [134]

Answer:

The opposite of 14 is -14.

Step-by-step explanation:

Opposites are numbers with the same distance from 0 but one is to the right of 0 and the other is to the left of 0.

The opposite of 0 is itself,0.

So the opposite of 5 is -5 since both 5 and -5 have the same distance from 0 and one is to the left and one is to the right of 0.

The opposite of 14 is -14 since both have the same distance from 0 and one is to the right and one is to the left of 0.

You can also think of this question as what can I add to 14 that will give me 0.

The answer is -14 since -14+14=0.

Another word for opposites is additive inverses.  When you add additive inverses you get 0.

Another example: What is the opposite of -16?  

The answer is 16 since 16+(-16)=0.

A value to describe the steepness of a strainght line
marta [7]
That depends if the line is vertical or horizontal. If the line is vertical, the slope (steepness) of the line is undefined (this is because the x values across the entire line are the same). If the line is horizontal, the slope of the line is 0 (this is because the y values will always subtract to equal 0 when you use the form y1 - y2/x1 - x2 to find slope).

Hope this helps.

In a normal curve, roughly what percent of all cases fall within plus or minus two standard deviations
Rainbow [258]

Answer:

We know that the total area under the normal curve is 100%. According to the empirical rule of Normal distribution:

Approximately, 68% of data lies within \pm1 standard deviations of mean.

Approximately, 95% of data lies within \pm2 standard deviations of mean.

Approximately, 99.7% of data lies with \pm3 standard deviations of mean,

Therefore, in a normal curve, roughly 95% of all cases fall within plus or minus two standard deviations.
