Your answer is false the upper quartile is the median as in middle number not mode.
period = 2, Amplitude = 2
AMPLITUDE
---------------------------------
f(t) = sin(t) , this function has an amplitude of 1 , because its y values goes one unit up, and one unit down from the x axis. to increase this to an amplitude of 2, we get f(t) = 2. sin(t). This means the graph is twice as tall as our original function f(t) = 1.sin(t).
PERIOD
----------------------------
the period has a formula: w = 2pi / |B | . The normal period for a sinewave
f(t) = sin(t) = 2 pi.
So in our new function f(t) = 2 sin (t) [ amplitude is now multiplied by 2], the period (as stated in the question) is 2, that is 2 pi (remember the formula for period stated 2pi) divided by b, which is now 2. Which means 2pi is now divided by 2 or multiplied by 1/2. 2pi /2 = pi or 1/2 x 2pi = pi. so as you increase the period in the equation, the sinewave becomes shorter.
ANSWER
------------------------------
So the function is actually f(t) = 2.sin(2t).
Answer:
5 hours
Step-by-step explanation:
$39 + $5.8*t < $73.80
To solve it, collect the constant terms on the right side:
5.8*t < $73.80 - $39 = $34.08
t < $34.08 divided by 5.8 = 5 hours.
Idk if this is correct, I had a question like this on a test and this is what I did. So plz don't be mad if it's wrong.
Answer:
z-score = 1.667
Step-by-step explanation:
The provided information are:
Population mean = 50
Population standard deviation = 6
Score (X) = 60
The formula to calculate the <em>z</em>-score is:
The z- score can be calculated as:
Hence, the z-score is 1.667.
