Schach [20]

Answer:

The original Slope is y=-1/3x-2

The perpendicular slope would be y=3x+b

Step-by-step explanation:

Original Slope:

You already have the y-interecpet, (0,-2), and you know two points (0,-2) and (-6,0), so you can find the slope with (y1-y2)/(x1-x2) so in this case, it would be (0-(-2))/(-6-0)= -1/3 and you can find y=1/3x-2.

Perpendicular Slope:

The slope of any perpendicular line would be the reciprocal of the original. So the reciprocal of -1/3 is 3. The b can be any real number because no matter the y-intercept the slope would still be perpendicular

Answer:

See explaination.

Step-by-step explanation:

Sampling distribution can be defined as a probability distribution of a statistic which is gotten through a large number of samples usually drawn from a specific population.

The sampling distribution of a given population can be described as the distribution of frequencies of a range of different outcomes that could possibly occur for a statistic of a population.

Please refer to attachment for a step by step technique to prove How many candy bars must you have in order to be sure the sampling distribution of x is normal.

3x power of 2+ 5x+2=0<br><br>what does x equal
In-s [12.5K]
Let's solve your equation step-by-step.
2+5x+2=0
Step 1: Simplify both sides of the equation.
2+5x+2=0
(5x)+(2+2)=0(Combine Like Terms)
5x+4=0
5x+4=0
Step 2: Subtract 4 from both sides.
5x+4−4=0−4
5x=−4
Step 3: Divide both sides by 5.
