Answer:
t(3u)
Step-by-step explanation:
First we have to triple (x3) u, which is what gets us 3u. Then we multiply that result by t.
This gives us: t(3u)
Remember, this problem is asking for you to write an expression, not and equation. That is why there is not an equal sign included in the answer.
X-5) = 2(x-1)
3x-15 = 2x - 2
x - 15 = -2
x = 13
If you type in both the coordinates it’ll give you the answer on google. That’s how I did this.
Answer:
d. The population standard deviation is known.
Step-by-step explanation:
T-distribution or Z-distribution, which to use?
If we have the population standard deviation is known, we use the z-distribution.
Otherwise, if we only have the standard deviation for the sample, we use the t-distribution.
Which of the following is not appropriate to use the t-confidence interval for
When the population standard deviation is known, so letter d.
Answer:
(final - initial/initial ) * 100
66 - 55/55 * 100
11/55 * 100
100/5
= 20 percent
