Answer:

lines a and b are parallel. The slopes are -1/3

None of the lines are perpendicular to each other.

Step-by-step explanation:

To figure out if any of the lines are parallel or perpendicular to each other, you have to find the slopes of each line. To find the slope look at the graph find the rise over run for all of the lines:

line a: This line goes down one every time it goes over 3, which can be represented by -1/3

line b: This lines goes down one every time it goes over 3, which can also be written as -1/3

line c: This line goes up 5 every time it goes over 2, which makes the slope 5/2

When two lines are parallel, they have the same slope. Line a and line b have the same slope, so they are parallel.

When two lines are perpendicular, their slopes are negative reciprocals of each other. Since none of the slopes are a negative reciprocal of another slope, we have no perpendicular lines.

Hope this helps :)

Hatshy [7]

Answer:

The 99% confidence interval for the mean peak power after training is [299.4, 330.6]

299.4\leq\mu\leq 330.6

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

The 99% confidence interval for the mean peak power after training is [299.4, 330.6]

Which number line correctly shows 4. 5 + 2. 5? A number line going from 0 to 4. 5 in increments of 0. 5. An arrow goes from 0 to
sesenic [268]

So none of the options is actually correct from the given operation of:

4.5 + 2.5

This actually would be represented with a line that goes from 0 to 4.5, and then from 4.5 to 7.

The number line should start at 0 and then move to the first number (because of the commutative property of the sum, it can move to any one of the two numbers).

Once there, it moves accordingly to the other number.

So it moves first from 0 to 4.5, then the second number is 2.5, then it moves another 2.5 units to the right until the:

4.5 + 2.5 = 7

Concluding, <u><em>it moves from 0 to 4.5, then from 4.5 to 7.</em></u>

Notice that none of the options represent this, this may be because the sign of one of the two numbers is incorrect or something like that.

For example, if we had the operation:

4.5 - 2.5

Then the line starts at 0 and then goes to 4.5, then moves left 2.5 units to 4.5 - 2.5 = 2

In this case, the correct option should be:

<u><em>"An arrow goes from 0 to 4. 5 and then backwards from 4. 5 to 2."</em></u>
