Answer:
x = 0
, y = 7/6
Step-by-step explanation:
Solve the following system:
{18 y - 12 x = 21
6 x - 9 = -9
In the second equation, look to solve for x:
{18 y - 12 x = 21
6 x - 9 = -9
Add 9 to both sides:
{18 y - 12 x = 21
6 x = 0
Divide both sides by 6:
{18 y - 12 x = 21
x = 0
Substitute x = 0 into the first equation:
{18 y = 21
x = 0
In the first equation, look to solve for y:
{18 y = 21
x = 0
Divide both sides by 18:
{y = 7/6
x = 0
Collect results in alphabetical order:
Answer: {x = 0
, y = 7/6
Two similarities between constructing a perpendicular line through a point on a line and constructing a perpendicular through a point off a line are;
- 1. Arcs are drawn to cross the given line twice on either side relative to the point
- 2. The perpendicular line is drawn using a straight edge by connecting the small arcs formed using the arcs from step 1, to the point on the line or off the line
Description:
1. One of the first steps is to place the compass on the point and from
point, draw arcs to intersect or cross the given line at two points.
2. The compass is placed at each of the intersection point in step 1 and
(opened a little wider when constructing from a point on the line) arcs are
drawn on one (the other side of the point off the line) side of the line with
the same opening (radius) of the compass to intersect each other.
3. From the point of intersection of the arcs in step 2, a line is drawn with a
straight edge passing through the given point.

Answer:
The 99% confidence interval for the mean peak power after training is [299.4, 330.6]
![299.4\leq\mu\leq 330.6](https://tex.z-dn.net/?f=299.4%5Cleq%5Cmu%5Cleq%20330.6)
Step-by-step explanation:
We have to construct a 99% confidence interval for the mean.
A sample of n=7 males is taken. We know the sample mean = 315 watts and the sample standard deviation = 16 watts.
For a 99% confidence interval, the value of z is z=2.58.
We can calculate the confidence interval as:
![M-z\sigma/\sqrt{n}\leq\mu\leq M+z\sigma/\sqrt{n}\\\\315-2.58*16/\sqrt{7}\leq\mu\leq 315+2.58*16/\sqrt{7}\\\\315-15.6\leq \mu\leq 315+15.6\\\\299.4\leq\mu\leq 330.6](https://tex.z-dn.net/?f=M-z%5Csigma%2F%5Csqrt%7Bn%7D%5Cleq%5Cmu%5Cleq%20M%2Bz%5Csigma%2F%5Csqrt%7Bn%7D%5C%5C%5C%5C315-2.58%2A16%2F%5Csqrt%7B7%7D%5Cleq%5Cmu%5Cleq%20315%2B2.58%2A16%2F%5Csqrt%7B7%7D%5C%5C%5C%5C315-15.6%5Cleq%20%5Cmu%5Cleq%20315%2B15.6%5C%5C%5C%5C299.4%5Cleq%5Cmu%5Cleq%20330.6)
