Answer:

The lowest ccommon denominator (or LCD) of 1/3 and 2/5 is 15.

Step-by-step explanation:

The lowest multiple of 3 and 5 is 3*5 = 15.

In terms with the LCD, 1/3 now equals 5/15; and 2/5 now equals 6/15.

Hope this helps :)

The ordered pair (1,81), (2,100), (3,121), 5,169).. represent a function. What is a rule that represent this function?

zloy xaker [14]

A rule that represents this function is y = (x + 8)².

The rule looks like √y = (x + 8)

Now square both sides

y = (x + 8)²

y = x² + 16x + 64

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]
